          One of the oldest and most powerful  corporeal races in existence, the Time Lords would be a fascinating species  even if they were not The Doctor’s own race, being one of the first races to  ever evolve sentience in the universe as it currently exists. Initially ruled  by the near-mystical seer known as the Pythia in the distant past of their home  planet, Gallifrey, the Time Lords were first formed when Rassilon rose up  against the Pythia and drove her away so that the Time Lords could progress  beyond the superstition of the old, although the Pythia’s curse of sterility  forced them to focus for a time on finding alternative methods of reproduction  rather than explore their interest in time travel.

                | 
             
           
            Having escaped the curse with the  aid of genetic looms that would ‘weave’ new Gallifreyians into existence,  Rassilon, accompanied by his associates Omega and the mysterious ‘Other’ - a  being whose true name and origins have been lost to history, said to have been  more powerful than Rassilon and Omega combined -, set out to provide their  people with the means of travelling in time by harnessing a black hole as a  power source. Using Omega’s research, they were able to turn a star supernova  and trap the resulting black hole for themselves, but the incident resulted in  Omega falling through the black hole into a realm of anti-matter ("The
    Three Doctors") - implied by later rumours to have been caused by Rassilon  sabotaging Omega’s equipment so that he wouldn’t have to share power  ("Omega") -, leaving Rassilon and the Other to establish a new  Gallifrey.  
           
            Although Rassilon was involved in  the creation of several Time Lord engineering miracles, including the Eye of  Harmony - the system responsible for containing the black hole Omega had  created - and the Matrix - a virtual telepathic network containing the memories  of all deceased Time Lords -, he was also said to be responsible for the  creation of some of their more questionable discoveries, such as the Timescoop,  a device that drew other races out of their proper places in time so that the  Time Lords could force them to compete against each other for their amusements  ("The
    Five Doctors"). During this time, the Time Lords’ early  experiments in time travel unleashed pure evil into the universe when they  opened a dimensional rift that allowed the first vampires to enter the  universe, prompting the Time Lords to wage war against the vampires, each one  individually capable of draining the life-force from an entire planet. Although  the Time Lords, led by Rassilon, defeated the original vampires using massive  bow-ships to pierce their hearts, the resulting war was so long and bloody that  the Time Lords were left sickened with violence ("State
    of Decay"),  ending the Death Zone and other sick entertainments. The Time Lords briefly  returned to war during the Millennium War of the future, Rassilon leading them  into the final battle of the races of the universe against insane supercomputer  the Mad Mind of Bophemeral, but their role in this conflict was forgotten when  the Six Guardians used the Key to Time to erase the universe’s memory of the  Millennium War to spare them from having to remember the terror of the vast  conflict ("The 
      Quantum Archangel").

                  | 
             
           
            As time went on, however,  Rassilon became increasingly corrupted by his power, weaving his own Web of  Time to maintain the causality of the universe the way he perceived it should  be, going so far as to banish the race known as the Divergence - revealed to  have been the race that would have evolved to surpass the Time Lords if nature  had taken its course - into the universe of anti-time, a continuous, unchanging  Now, in order to prevent his people being replaced. He was also responsible for  locking away magic and related powers from the rest of the universe in order to  impose order and rationality on it, with some sources even suggesting that he  deliberately influenced the subsequent evolution of all life in the universe so  that it would follow a pattern to create races similar in appearance to the  Time Lords (Although other sources suggest that the Time Lords’ evolution  simply influenced the universe’s morphic field to shape future evolution on a  path that had already been ‘proven’ to work rather than it being the result of  deliberate action). As Rassilon became increasingly corrupt - to the point that  he led a war against another race of vampires that simply fed on  genetically-engineered crops rather than other sentient beings simply because  he saw them as being too different to live -, the Other committed suicide by  throwing himself into the genetic Looms in protest of Rassilon’s new policies,  with his granddaughter - the last natural birth on Gallifrey - leaving the  planet shortly afterwards under undisclosed circumstances to escape being  prosecuted by others. Despite this, Rassilon continued his experiments in his  foundry, developing a series of biogenic molecules that would grant the Time  Lords the power of regeneration, as well as the creation of the Matrix, a vast  computer network where the mental imprints of deceased Time Lords would be  stored, Rassilon uploading his own consciousness into the Matrix at the moment  of his death so that he could maintain full existence within the Matrix.

                  | 
             
           
            From this point onwards,  Time Lord society ‘progressed’ in a relatively stable manner, cutting  themselves off from the rest of the universe as they established their position  as the lords of Time, preventing unauthorised time-travel while ensuring that  the timelines remained as they should, only watching the events taking place  around them and never interfering. To this end, their time machines - the  TARDISes, dimensionally transcendental machines that were bigger inside than  outside - were all equipped with fully-functional chameleon circuits, ensuring  that travelling Time Lords would be able to visit locations in history and  observe from the safety of the TARDIS interior without anyone knowing that they  were there. Although they occasionally attempted to interfere to ‘improve’  history, they abandoned this policy after their actions often made things  worse, such as essentially splitting the planet Minyos in half in a nuclear war  when the Minyans abused the advanced technology the Time Lords gave them  (Underworld"), teaching the people of Klist how to reverse evolution  with tragic results, and sending the inhabitants of the starlit ring of  Plastrodos 14 utterly mad ("The Quantum Archangel") (Although they  were able to protect a tribe of Celts from Roman invaders by using Time Lord  technology to send the tribe into the dream world of Avalon, powered by the  dreaming mind of King Constantine ("The 
      Shadows of Avalon")). By the  time that The Doctor was born, Time Lords focused on passively observing the  universe around them, with the Celestial Intervention Agency - a small, secret  group who monitored the Web of Time to ensure that other races did not attempt  to alter history for their own purposes - the only race who actively interfered  in the rest of the universe, and most of their experience was theoretical  rather than practical. Although some Time Lords would retire from life on  Gallifrey to settle down on other worlds - such as Azmael, former coordinator  of the Matrix, becoming ruler of the planet Jaconda ("The
    Twin Dilemma"), or Rummas becoming the head of the Library of Carsus, the greatest  repository of knowledge in existence ("Spiral
        Scratch") -, in general  they avoided interference, their existence becoming legend more than fact as  they merely observed the affairs of the universe rather than taking action.

                  | 
             
           
            This status quo continued  until, several centuries after the Other’s death, the Time Lord who would  become known as The Doctor was born into the House of Lungbarrow, one of the  oldest Houses on Gallifrey (Some sources suggest that he was the product of a  Time Lord father and human mother ("The
			 Room With No Doors" and  "The Gallifrey Chronicles"), but these are of questionable accuracy  at best). Although Quencessetianobayolocaturgrathadadeyyilungbarrowmas  - Quences for short -, the Kithriarch and head of the House of Lungbarrow, had  high hopes for the young Time Lord, he rejected most of the Kithriarch’s  ambitions, preferring to simply focus on acquiring his doctorate, to the point  where he asked to be called ‘Doctor’ rather than being referred to by his other  nicknames such as ‘Theta Sigma’, ‘Wormhole’ or ‘Snail’ (Receiving the last two  because of the anomaly of him possessing a belly-button despite the fact that  he was born from the Loom), with only his Cousin Innocet ever showing him any  real kindness. Although his attitude towards his studies was lax at best,  Quences continued to believe in the ‘prediction’ that The Doctor would be the  most influential Time Lord since Rassilon, despite The Doctor’s defiance of his  orders. Although The Doctor was prominent enough in his studies to be one of  the Deca - the ten greatest Time Lords of their year, including himself, Ushas,  Koschei, Magnus, Mortimus, Jelpax, Vansell, Drax, Rallon and Millennia -, the  Deca were shattered when The Doctor’s attempt to shake up the Time Lords by  confronting the ancient being known as The
      Toymaker resulted in Rallon being  taken as the Toymaker’s host, Millennia being trapped as a living doll, and The  Doctor being expelled and reduced to traffic duty ("Divided
         Loyalties"). He was able to reapply to the Academy after obtaining his  doctorate, but he never committed himself to his studies and only passed his  qualifying exams to become a Time Lord with 51% on the second attempt, with the  rest of the Deca breaking up even further over time (Particularly after Vansell  was revealed to be an Agency operative sent to spy on The Doctor). Increasingly  distanced from the rest of his Family, The Doctor was even Disowned and  replaced with a new Cousin, Owis, although his family still regarded Owis as a  grave disappointment, with Quences continuing to prefer The Doctor despite his  estrangement. Increasingly jealous of The Doctor, Glospin, another Cousin,  researched Lungbarrow’s Loom records and discovered evidence that suggested  that The Doctor wasn’t a true Cousin of the House of Lungbarrow, but as he and  The Doctor fought, Glospin revelling in the thought of The Doctor being  executed as a ‘Loom-jumper’ and thus ensuring Glospin’s birthright, the Hand of  Omega mysterious appeared, scarring Glospin’s arm and prompting him to flee  ("Lungbarrow").

            Disgusted at Glospin’s accusations and shaken at  the appearance of the Hand of Omega (As well as being haunted by  an old prophecy of a hybrid Time Lord who would rule Gallifrey’s ruins that he  had discovered in the Matrix as a child ("Heaven Sent/Hell Bent")), The Doctor departed Gallifrey in a Type 40  TARDIS acquired from a nearby dock - he had  briefly contemplated taking a Type 53, but found it too soulless compared to  the Type 40 -, only for the presence of the Hand of Omega on the ship caused  The Doctor to travel back into Gallifrey’s own past, neatly bypassing the  transduction barriers preventing Time Lords from making such a journey. Now  unable to return to Gallifrey even if he wanted to, The Doctor found and  adopted the Other’s granddaughter - who ‘recognised’ him as her grandfather  even as he somehow knew that her name was Susan - before departing Gallifrey  with her ("Lungbarrow"). Although the Time Lords went looking for The  Doctor - particularly since the entire house of Lungbarrow mysteriously  vanished on the same day as he left Gallifrey -, he made it difficult for them  to track him by designing his own controls for the TARDIS, sacrificing  precision control to prevent himself from forming a full mental link with the  ship that would have left a signal that the Time Lords could track ("The 
      Taking of Planet 5"), allowing The Doctor to remain on the run from other  Time Lords for several years at the cost of not being able to completely  control where he was going, with only the occasional encounter with fellow  renegades Mortimus - now calling himself  The Meddling
      Monk ("The 
      Time Meddler") - and Koschei - later to be known as The Master - ("The
			 Dark Path") to serve as contacts with his home. During his travels, The  Doctor found himself often accepting the company of various humans, beginning a  trend of travelling through time with others, as well as encountering several  alien races - including a rematch with the Toymaker ("The
    Celestial Toymaker") -, but the most crucial threat he would face were the Daleks ("The
    Daleks"), a race that would go on to have a particular impact  on the Time Lords as a whole, the Daleks developing time travel simply to find  The Doctor ("The 
      Chase"), tensions between The Doctor and the Daleks  escalating when The Doctor was able to trick the Daleks into engaging in civil  war ("The
    Evil of the Daleks"). 
           
            Although Susan eventually  left The Doctor to settle down on Earth after they defeated a Dalek invasion  ("The 
      Dalek Invasion of Earth") - The Doctor wanting to protect her  after he acted to deliberately change a history that he’d experienced  ("The
    Time Travellers") -, he was eventually caught by the Time Lords  when he was forced to contact them for aid after ending the War Games, an alien  experiment - aided by his old friend Magnus, now known as the War
                 Chief - where  human soldiers from various periods in history were taken out of time and  pitted against each other to create a conquering army, the Aliens’ time  machines having broken down and The Doctor unable to return the soldiers home  on his own ("The
    War Games"). Although the Time Lords were initially  prepared to execute The Doctor for his theft of the TARDIS and interference in  the affairs of the universe, the subsequent discovery of something interfering  in human history around the Napoleonic Wars - later revealed to be the  mysterious Players - prompted the Agency to arrange for The Doctor’s life to be  spared, offering to lower his sentence to exile on Earth - a world that the  Time Lords had noted was vulnerable to alien interference and would therefore  allow The Doctor to continue his fight against evil - if he would act as their  agent in a few important missions that they needed to carry out to preserve the  stability of history while maintaining their official policy of  non-interference ("World
    Game"). After going on various missions for  the Time Lords - one mission even resulting in him being captured and requiring  rescue by his sixth incarnation when the Sontarans sought to harness the power  of time travel ("The
    Two Doctors") -, The Doctor was sentenced to  regeneration and exiled to Earth, his memory of the TARDIS dematerialisation  codes lost and certain vital components damaged, forcing him to officially join  UNIT as a scientific advisor to defend Earth and gain access to the technology  needed to repair the TARDIS ("Spearhead
    From Space").

                  | 
             
           
            Even during his exile, the  Time Lords kept an eye on The Doctor, contacting him to warn him about The  Master’s arrival on Earth ("Terror
    of the Autons") and even  occasionally reactivating the TARDIS so that The Doctor could complete  additional missions for them, such as preventing The Master from acquiring an  ancient doomsday weapon ("Colony
        in Space") or ensuring that a  crucial galactic conference on the planet Peladon went smoothly ("The
    Curse of Peladon"). When Omega - still alive in the anti-matter universe  on the other side of the black hole - attempted to escape back into the real  universe by draining power from Gallifrey and forcing The Doctor to take his  place, the Time Lords were forced to break the First Law of Time and send the First Doctor and Second Doctor to aid the Third Doctor. Working together, the three Doctors  were able to defeat Omega by tricking him into bringing matter and anti-matter  together - he converted them into anti-matter when he drew them into his world,  but the Second Doctor’s recorder fell into the TARDIS forcefield generator and  remained matter, allowing them to use it as a weapon -, with the Time Lords  lifting the Third Doctor’s exile as thanks for his role in saving them  ("The Three Doctors").

            Although now officially a  free agent, The Doctor was occasionally called upon by the Time Lords to act as  their agent in exchange for the freedoms they allowed him, such as when they  sent him to avert or alter the creation of the Daleks ("Genesis 
      of the Daleks"); although The Doctor failed in his mission because he felt that  the moral consequences of such a victory would make him no better than the  Daleks, his actions did delay the Daleks by a thousand years (The resulting  distortion requiring the Time Lords to send The Doctor a new TARDIS to recover  his companions ("A
			 Device of Death") before they sent him on another  brief mission to prevent the Cybermen from destroying Voga, the planet of gold  ("Revenge 
      of the Cybermen")), with some fans speculating that the  Daleks’ later ‘dependence’ on Davros when circumstances required them to draw  on his independent mind is another sign of the Daleks having been weakened by  The Doctor’s interference. After another period of travelling independently -  although some speculate that the Time Lords were responsible for The Doctor’s  visit to the planet Karn in time to stop the reanimated brain of renegade Time  Lord Morbius ("The
    Brain of Morbius") -, The Doctor returned to  Gallifrey during the retirement of the current President of the Time Lords,  where he became involved in The Master’s plan to draw energy from the Eye of  Harmony to restore himself after the loss of his regenerations ("The
    Deadly Assassin"). During this adventure, The Doctor was indirectly  elected to the position of Lord President - submitting himself as a candidate  to give himself freedom to investigate the previous president’s death and  becoming the only candidate when he discovered that Goth, his ‘rival  candidate’, was working with The Master -, but he only officially assumed the  role when he briefly returned to Gallifrey to defeat an invasion of Gallifrey  that had been organised by the Vardans and the Sontarans ("The
    Invasion of Time"). Having pretended to be aiding the Vardans in order to stop a less  scrupulous Time Lord from helping them, The Doctor trapped the Vardan home  world in a time loop and used the forbidden De-Mat Gun to erase the Sontaran  leader from history, subsequently appointing his old friend and teacher Borusa to the position of President in his place before he departed, leaving his  companions Leela and K9 on Gallifrey after Leela fell in love with Andred, one  of the Chancellory Guards. 
           
            Although it would be some  time before The Doctor’s next return to Gallifrey, he was given an interesting  new connection to his people when The White Guardian of the universe sent him a  Time Lady to become his new companion in the form of Romanadvoratrelundar, who  would assist him and the new K9 in their search for the powerful Key to Time  ("The
    Ribos Operation"). Although initially confident in her academic  superiority over The Doctor, Romana came to admire his independent mind and  ability to think on the spot, inspiring her to regenerate into a new  incarnation that was able to get along with The Doctor more easily  ("Destiny
    of the Daleks") - although later evidence suggests that  Romana’s regeneration was influenced by various outside factors, such as her  transformation into the new sixth segment of the Key ("The
        Chaos Pool") and an attempt by the remnants of Gallifreyian dictator Pandora to  influence her psyche ("Gallifrey:
    Lies") -, her new incarnation  bonding with The Doctor to such an extent that Romana even expressed reluctance  to return to Gallifrey when the time came for the Time Lords to order her to  return ("Meglos"). As a result, when the TARDIS briefly accidentally  travelled into the pocket dimension of E-Space ("Full
    Circle") - defeating  the long-lost Great Vampire in the process ("State of Decay") -,  faced with a chance to return to their universe, Romana decided to remain in  E-Space to help the people that she and The Doctor had met in that universe,  concluding that it was best to be her own person ("Warriors'
    Gate").  Although the Time Lords were dissatisfied at The Doctor’s defiance of their  orders to return Romana to Gallifrey, they accepted his argument that Romana  chose to remain in E-space on her own, although their acceptance was most  likely aided by the fact that The Doctor had saved the universe from death by  entropy shortly after his return - although it cost him one of his lives -  ("Logopolis") and his later defeat of the returned Omega despite  Omega’s attempt to use The Doctor’s biodata to create a new body for himself  ("Arc
    of Infinity").

                  | 
             
           
            The Doctor was drawn back  into Time Lord politics when Borusa, his mind warped by the strain of the  Presidency and a recent regeneration, resolved to rule Gallifrey forever,  bringing together The Doctor’s first five incarnations to penetrate the  defences surrounding Rassilon’s tomb and claim his supposed secret of  immortality (Although the Fourth Doctor was trapped in a time loop due to the  equipment malfunctioning when Borusa tried to extract him). However, despite  The Doctors’ success, Borusa was defeated when the First Doctor realised that  the immortality promised was a trap set by Rassilon to remove dangerous Time  Lords, leaving their former teacher trapped as living stone ("The Five  Doctors"). With Borusa’s defeat, the Fifth Doctor was appointed to the  position of President after his past selves had returned to their proper place  in time, but he quickly rejected the offer in favour of returning to the TARDIS  and fleeing Gallifrey after appointing Chancellor Flavia as acting President  while he claimed to need a brief time away to sort out some loose ends,  satisfied that Flavia would make a good President who wouldn’t spend too much  time looking for him. While the Time Lords played an indirect role in The Doctor’s  life at this point, such as subtly directing the Sixth Doctor’s TARDIS into a  position where he could thwart the Cybermens’ attempt to change history by  crashing Hayley’s Comet into Earth in 1985 to prevent Mondas’s destruction  ("Attack
    of the Cybermen" and "The
    Tenth Planet") or  allowing the Sixth Doctor to rescue the Second when the younger Doctor was  captured during his period of ‘employment’ by the Celestial Intervention Agency  ("The Two Doctors" and "The 
      Eight Doctors"), in general  they appeared content to allow The Doctor to freely wander once again after  this point rather than try and lure him back to Gallifrey. During his travels,  the Fifth Doctor briefly visited Gallifrey in his recent past when he was  forced to recruit the Time Lords of that era to defeat Morbius’s plans of  galactic conquest - the Time Lords funding The Doctor’s attempt to raise an  army of alien races against Morbius’s own forces -, but he swiftly left the  Time Lords after the final battle as he recognised that the three Time Lords  who had been helping him had their own reasons for wanting him to stay  ("Warmonger").

            The Doctor’s time away from  the Time Lords of his present ended when he arrived on the planet Ravalox,  which he soon discovered was really Earth, having been taken from its proper  place in time and space and relocated to another part of the universe after the  Time Lords discovered that a group of thieves from Andromeda had set up a base  on Earth while stealing secrets from the Time Lord Matrix ("The
      Mysterious Planet"). In an attempt to conceal the theft and their failure, the  Celestial Intervention Agency had arranged for a puppet President, Niroc, to be  elected so that they had the authority to order Earth moved - the transition  creating a fireball that destroyed virtually all life on the planet’s surface  while the survivors, hidden underground when the fireball struck, socially  regressed -, subsequently putting The Doctor on trial for interfering in the  affairs of the universe so that he could be executed before he could reveal the  truth ("The Trial of a Time Lord"). This renegade High Council was so  desperate to ensure a conviction that they even violated multiple laws of time  to create the perfect prosecutor for the trial in the form of The
                 Valeyard, a  manifestation of The Doctor’s dark side created at the moment of the Twelfth Doctor’s regeneration (The exact methods used to create him were unspecified).  However, despite the Valeyard’s attempt to manipulate the evidence to portray  The Doctor as violent and unstable, seemingly betraying his companion Peri to  save himself ("Mindwarp") and committing genocide against the  artificially-created Vervoids ("Terror of the Vervoids"), their  actions were exposed when The Master sent vital witnesses to aid The Doctor in  defeating his dark side, as well as the Eighth Doctor rescuing his past self  from the Valeyard’s attempt to force a timeline where The Doctor was executed  ("The Eight Doctors"). While the Sixth Doctor defeated the Valeyard  and The Master in the Matrix, the Eighth Doctor arranged an inquiry into recent  events on Gallifrey thanks to his role as ex-President of Gallifrey, exposing  the Agency’s schemes before convincing Rassilon to release Borusa -  simultaneously regressing Borusa back into a more stable incarnation - so that  his political skills could calm the other Time Lords and allow for a new High  Council to be established. 
           
            With the crisis on  Gallifrey resolved, The Doctor returned to his old role as a traveller in time  and space - albeit briefly contemplating exiling himself to one planet to  escape his future as the Valeyard before the Time Lords assigned him a new  mission ("Time
			 of Your Life") -, although from this point onwards  Gallifrey’s contact with his timeline, which had once been relatively linear, was  now increasingly erratic, with Gallifrey sometimes encountering an earlier or  later Doctor than the one that ‘should’ exist at this time. From Gallifrey’s  perspective, it would appear that, after the political crisis of The Doctor’s  trial had been resolved, Borusa returned to his imprisonment with Rassilon as  he did not feel that he deserved freedom yet, remaining trapped until a  renegade group of Time Lords, led by Goth’s younger brother, attempted to pit  the ancient vampire Agonal against Rassilon to force him to free Borusa  ("Blood
			 Harvest"). However, with the aid of the Seventh Doctor and  Romana - now returned from E-space after thwarting an attempt to resurrect the  Great Vampire -, Borusa and Rassilon defeated Agonal, Borusa being subsequently  allowed to pass on at last. Romana’s return to Gallifrey would result in a  crucial change in Time Lord policy, encouraging Gallifrey to open its  transduction barriers and share its secrets with the universe rather than hide  away from the rest of civilisation (Although they were still determined to  maintain a monopoly on time travel). Returning to Gallifreyian society, Romana  began a new political career that culminated in her becoming President, only  for her to be captured by the Daleks and held prisoner for twenty years until  she was rescued by the Sixth Doctor during a Dalek invasion of Gallifrey  ("The Apocalypse Element"). 
             Returned to power, Romana  continued her efforts to improve Gallifrey’s relationships with other worlds,  but this effort was nearly jeopardised when the Seventh Doctor finally returned  to his old House of Lungbarrow, buried underground for 673 years, leaving him  to confront his family - all of whom blamed The Doctor for Quences’ murder and  the House subsequently sinking underground - with only Chris Cwej for company  while Leela, Ace and Romana found themselves dealing with an Agency  investigation that sought to fill in the blanks of The Doctor’s past and  undermine Romana’s presidency. Despite the crisis forcing The Doctor’s  companions to enter his subconscious and confirm his identity as the Other,  they dismissed this as irrelevant as even The Doctor hadn’t remembered that  part of his past before then, with The Doctor reflecting that what he had been  in the past no longer mattered and all that was really important was his  current identity as The Doctor. With this personal mystery resolved, The Doctor  proceeded to expose Quences’ true killer as Glospin, who had acquired a sample  of The Doctor’s DNA and regenerated into the First Doctor’s double to kill  Quences before regenerating again to conceal his guilt and frame The Doctor,  subsequently allowing the House to be destroyed so that his surviving family  could begin to grow a new one, with Innocet taking over as the head of the  House. As Gallifrey opened its doors to outsiders for the first time in  centuries, The Doctor departed once again, leaving Chris on Gallifrey to sort  out his identity after so long with The Doctor ("Lungbarrow").  Although he had been assigned a mission to collect The Master’s remains from  Skaro, The Doctor initially spent some time travelling alone, during which a  particular crisis resulted in his new companion, Elizabeth
             Klein ("Colditz" and "A Thousand Tiny Wings") stealing the TARDIS  ("Survival
    of the Fittest") and using it to change history until The  Doctor undid her actions by erasing her from history ("The
        Architects of History"). This incident aside, in general the Time Lords seemed willing  to let The Doctor do what he wanted at this point, to the extent that The  Doctor briefly made a deal with Death to try and give The Master a chance at  peace before his own demise, although the plan still failed despite his best  efforts ("Master").

  Having finally collected  The Master’s remains - only for The Master’s last attempt to save himself  resulting in The Doctor regenerating and Earth nearly being sucked into the Eye  of Harmony before The Doctor stopped him ("Doctor
    Who: The Movie") -,  the Eighth Doctor unintentionally attracted the Time Lords’ direct attention  during a visit to 1933, when he accidentally saved Charlotte ‘Charley’Pollard from the accident that was meant to have killed her in recorded history  ("Storm 
      Warning"), her survival causing an ever-increasing amount of  distortions in the web of time. These disruptions continued to escalate until  they created a rift into the universe of anti-time - the opposite of regular  time, comprising a void of unchanging Now -, which The Doctor was only just  able to seal by using the TARDIS ("Neverland"). Although The Doctor  was briefly contaminated by anti-time energies and corrupted into the  destructive Zagreus thanks to the machinations of Rassilon - whose personality  remained active within the Matrix - as he sought to destroy the Divergents, a  race that would have evolved to surpass the Time Lords before he trapped them  in the realm of anti-time, by using Zagreus as his assassin, Charley, Leela and  Romana were able to restore The Doctor’s personality to normal, although he  subsequently exiled himself to the universe of anti-time as he was still  infected by the anti-time energies ("Zagreus"). While The Doctor was  exiled in the anti-time universe, Romana and Leela faced their own challenges  on Gallifrey, ranging from corruption within as the Celestial Intervention  Agency acted against Romana - resulting in Leela and Andred divorcing when  Andred regenerated and faked his death to infiltrate the Agency - to a  declaration of civil war as Pandora, a Gallifreyian dictator from the distant  past, manifested in a new physical form based on Romana’s first incarnation.  Pandora was eventually destroyed, but the war resulted in the destruction of  the original K9, Leela being rendered blind by a grenade detonating ahead of  schedule, the death of Andred before he and Leela could reconcile, and the destruction  of the Matrix, to say nothing of a mind-altering virus being released by the  ‘Free Time’ organisation, a group that objected to Gallifrey’s monopoly on time  travel, that would corrupt the infected Time Lords to share their point of  view. Seeking a cure for the Free Time Virus, Romana, Leela and K9 began to  travel to various other Gallifreys in parallel universes - one world curing  Leela’s blindness through a transfusion of vampire blood -, eventually settling  in a world where Gallifrey had never acquired time travel, where they were able  to find a cure for the virus, although Romana required the aid of a plan  developed by a future version of herself to fully restore Gallifrey after they  returned to their original universe. 
 
  Even after the Free Time crisis  was resolved and their civilisation restored, the Time Lords continued to face  challenges, most notably in the form of the discovery of the Future War, a War  that Braxtiel had learned about that would pit the Time Lords against an  initially-unidentified Enemy. This war was so terrifying in scope that some  Time Lords from the time when this war had begun actually cut themselves out of  existence to become the mysterious Celestis, existing on the border of the  universe between reality and imagination. During his travels, the Eighth Doctor  - having eventually returned to the universe, - occasionally found himself  learning information about the Future War despite his efforts to avoid learning  such information. These discoveries included the knowledge that the Time Lords  of the future used advanced, sentient Type-103 TARDISes - as well as learning  that his thirteenth incarnation would apparently die for good in the first days  of the War - ("Alien 
      Bodies"), that the Time Lords of the future had  planted a doomsday weapon in Earth’s solar system that could annihilate  humanity and Time Lords alike if activated ("Interference:
         Book Two  - Hour  of the Geek"), and that the Time Lords would eventually become desperate  enough to release The Fendahl, the Thing That Eats Death ("Image
    of the Fendahl") from its time-looped prison to try and use it in the War  ("The 
      Taking of Planet 5"). Although The Doctor was content to just  travel as he always had - although he took action to interfere in the War when  he discovered evidence of future Time Lords attempting particularly devastating  plans, he always limited any knowledge he might receive about the conflict in  terms of who the Enemy were or how the War was progressing on a larger scale -,  the Time Lords of his present began to take steps to prepare for the War,  including the returned Romana regenerating into a third incarnation that was  more psychologically suited for the decisions she would have to make during the  War.

  Her attempts to prepare for the war  resulted in Romana coming into conflict with The Doctor when it was revealed  that his new companion Compassion was the ‘mother’ of the Type-103 TARDISes,  having mutated into the sentient Type-102 TARDIS due to a receiver that had  been implanted into her being linked to The Doctor’s TARDIS and processing the  signals from the ship as block transfer computations that altered her very  being ("The 
      Shadows of Avalon"). Refusing to allow Compassion to be  used as breeding stock, The Doctor fled from the Time Lords with her and Fitz Kreiner after the apparent destruction of his own TARDIS, fitting her with a Randomiser  to ensure that their travels would be as random as possible ("The 
      Fall of Yquatine"). However, despite The Doctor’s best efforts, the Time Lords  were still able to send various agents to some of the more likely locations  that The Doctor’s ship would visit, resulting in one agent acquiring the seed  code of Compassion’s Randomiser ("The 
      Banquo Legacy"), which they  were able to use to track Compassion’s next location, forcing Compassion to  flee to a ‘safe’ location in the form of the mysterious Edifice, a massive  object made of bone in the shape of a Gallifreyian flower of remembrance, a  symbol of death, that had appeared above Gallifrey. Trapped on his homeworld,  The Doctor learned that he had been infected by a Paradox biodata virus that  would turn him into an agent of Faction
                   Paradox when they had altered his  timeline and killed the Third Doctor ahead of schedule ("Interference:  Book Two - Hour of the Geek"), forcing him to help the Time Lords  investigate the Edifice in exchange for their help curing the virus. Exploring  the Edifice, The Doctor discovered that it was his presumed-destroyed original  TARDIS, which had taken the Paradox virus into itself to save him and fought to  remain intact even after its near-destruction, but the temporal ripples created  by the ship’s actions were not only drawing in the Enemy to mount their first  strike, but also gave the Faction the chance to summon the personification of  their god, Grandfather Paradox, into existence... the Grandfather manifesting  as the version of The Doctor who would result from The Doctor’s infection with  the virus. With no other way to avert the War as the Faction and the Enemy  attacked Gallifrey, The Doctor was forced to remove the Edifice’s dimensional  stabilisers and fire its ancient weapon systems, draining all the power holding  the Edifice together in one moment. Although this erased the timeline where The  Doctor regenerated on Dust as the Edifice lost the ability to contain both  realities, simultaneously erasing Faction Paradox from existence as their  founder ceased to have ever existed, the resulting energy release destroyed the  entirety of Kasterborus, eliminating all other Time Lords, The Doctor only  surviving thanks to Compassion saving him and the Edifice, now shrunk down to a  small box about an inch in size due to the loss of power ("The 
      Ancestor Cell"). Deciding to travel on her own with Gallifreyian technician Nivet  to maintain her systems, Compassion left The Doctor - now suffering from total  amnesia, attributed to the trauma of having to destroy his entire planet - on  Earth in 1889 ("The 
      Burning") before taking Fitz into 2001 to meet  him ("Escape 
      Velocity"), the TARDIS regenerating and repairing itself  over the subsequent century until it was restored to its original Police Box  shape, now relying on an independent power source as the amnesic Doctor resumed  his travels. 
 
  With the Time Lords now  gone from the universe, the magic that they once bound away has become easier  and more prevalent, such as The Doctor once facing a water spirit ("The 
      City of the Dead"), or a crisis involving werewolves, the Holy Grail, and  Morgraine le Fay ("Wolfsbane") (The last actually reaching into The  Doctor’s past, forcing the Fourth Doctor to deal with the after-effects of the  crisis while the Eighth dealt with the immediate threat). Although time travel  was also now more common than it had been - beginning with The Doctor  discovering a crack commando squad from the far future in a 1930s village  ("Eater 
      of Wasps") and progressing to include various other  time-active races -, the Time Lords’ knowledge had been so important that it  had become dispersed around the universe with their erasure, allowing various  groups to assume the Time Lords’ place in history to ensure that the worst of  the potential damage that they had once eliminated was dealt with ("The 
      Adventuress of Henrietta Street"), although some races such as The Onihr were also able to try and acquire remnants of Time Lord technology for their  own purposes ("Trading 
      Futures"). During an encounter with a group of  pan-dimensional beings representing the superstition that the Time Lords had  long suppressed which now sought to escape, The Doctor encountered a man who  claimed that there were only four ‘Elementals’ - beings like The Doctor and  himself - left in existence ("The Adventuress of Henrietta Street"). During  one particular trip to Earth, The Doctor had a brief encounter with Marnal - a  Time Lord agent who was exiled to Earth after his aggressive approach to  protecting Gallifrey turned a scavenger race of large flies into a dangerous  threat -, where he learned that he had erased his memory to transfer the  contents of the Time Lord Matrix into his subconscious, suggesting that he might  be able to restore Gallifrey in some way ("The Gallifrey  Chronicles"); the precise aftermath of these events is unclear, but it  would appear that The Doctor was able to restore Gallifrey and the Time Lords,  as well as his own memory. Following this restoration, The Doctor resumed his solo travels, but soon gained a new companion in the form of Lucie Miller, who was 'assigned' to him as part of a Time Lord 'witness protection program' ("Blood of the Daleks"). Even after this was proven to be a mistake as the Time Lords sent the wrong person, The Doctor and Lucie continued to travel together, facing threats such as the resurrected Morbius ("Sisters of the Flame/The Vengeance of Morbius"), but a chain of events led to The Doctor facing the return of his old foe the Meddling Monk. Bitter and jealous of The Doctor after he thwarted his foe's latest plans to 'improve' history, The Monk went so far as to assist the Daleks in their latest attempt to invade Earth, which led to the deaths of Lucie Miller, recent companion Tamsin Drew, and even Alex Campbell, The Doctor's great-grandson ("To the Death").
          Increasingly bitter after these losses, The Doctor attempted to take the TARDIS into the far future to find some hope, but was redirected by the Time Lord agent Straxus to investigate a temporal anomaly in the history of Molly O'Sullivan, a nurse in the First World War ("Dark Eyes: The Great War"). The Doctor learned that Molly's history had been manipulated by Kotris, a renegade Time Lord (in a bizarre twist, Straxus' own future self), who sought to use her as the power source of a weapon that could erase the Time Lords on behalf of the Daleks ("Dark Eyes: X and the Daleks"). This particular plan was defeated, but Molly and The Doctor were reunited when the reborn Master and the Dalek Time Strategist attempted to use her artron energy to take control of the powerful Eminence. After Molly sacrificed herself to stop the Eminence, The Doctor continued his travels with med-tech Liv Chenka, but soon found himself forced to hunt the Eleven, the latest incarnation of Time Lord criminal the Collective, who suffered from an illness known as regenerative dissonance that caused all of his past personalities to remain active in his mind after his regenerations ("Doom Coalition"). The Doctor and Liv made a new friend during their search in the form of librarian Helen Sinclair, but eventually learned that the Eleven's escape had been part of a complex plan by Padrac, an old friend of The Doctor's who had become convinced that Gallifrey could only survive if every other planet in the universe that might threaten them was destroyed.

   Despite the Eighth Doctor's success in restoring Gallifrey, his efforts proved to be for nothing when the Daleks launched a new assault on the universe, beginning a massive Time War between the Time Lords and the Daleks which resulted in both sides being regarded as monsters by the rest of the universe; the Time Lords were so desperate to achieve victory that they even resurrected The Master ("Utopia" and "The Sound of Drums/Last of the Time Lords") and Rassilon ("The End of Time") to serve as a warrior and a leader in the conflict respectively. Although The Doctor tried to stay out of the war at first, he often found himself drawn into various Time Lord plots, such as trying to protect a powerful Time Lord psychic who had turned himself human to try and escape the conflict ("One Life") or destroying a Time Lord weapons depot created by destroying the history of the homeworld of his new companion Bliss ("The Lords of Terror"). At one point the War was briefly ended when The Valeyard - reborn after an accident involving a genetic resequencing device and a transmat system and 'conscripted' into the conflict - was able to use a stolen Dalek weapon to erase the Daleks from existence ("The War Valeyard"), but the Dalek Time Strategist was able to escape into a parallel universe, manipulating an alternate version of Davros into helping the Strategist recreate the Dalek empire by merging aspects of various alternate Skaros into one reality ("Palindrome"). Eventually, after The Doctor failed to save a young woman from her crashing ship because she refused to be aided by a Time Lord - the woman going so far as to say there was now no difference between the Time Lords and the Daleks - his subsequent injuries and an encounter with the Sisterhood of Karn ("The Brain of Morbius" and "Sisters of the Flame") forced The Doctor to regenerate once again, accepting a potion from the Sisterhood that would ensue that his new incarnation would be a warrior capable of fighting in the Time War. As the War continued, a small faction of Time Lords became so sickened by the conflict that they actually sought peace with the Daleks, creating a zone of null time that they believed the Daleks would be 'content' to rule over, only for The Doctor to expose the Daleks' true plans of inserting engines into multiple planets in the null zone and firing the planets at Gallifrey's defensive barriers ("The Heart of the Battle").

  While ostensibly fighting for the Time Lords, the incarnation that would become known as 'The War Doctor', while rejecting his past identity as The Doctor would never be capable of doing what had to be done, still held on to his morality when it counted, questioning some of the Time Lords' more desperate plans to ensure their superiority in the conflict, such as averting a plan to resurrect dead Time Lord soldiers or stop the acquisition of a weapon that could have theoretically erased the Daleks from history ("The Neverwhen"), although this was both because of his obvious moral objections and greater practical dangers. Despite this, the War Doctor also acted to protect Gallifrey when they were faced with particularly great threats, such as averting an attempt to disrupt the timeline of the Eye of Harmony ("War Doctor 3 - Eye of Harmony") or prevent Gallifrey being essentially consumed by the mysterious Enigma Dimension ("War Doctor 4 - The Enigma Dimension"). However, during his confrontation with the Enigma Dimension, the War Doctor actually proposed that the Enigma Dimension destroy both the Time Lords and the Daleks, concerned that his people had fallen so far that they would look for another enemy to fight if the Time War ended after so long as soldiers, even as the Enigma Dimension's impression of The Doctor through his companion Leela convinced them to spare both races instead. 
 
  Eventually, the War became so desperate that The Master actually fled in fear 
as he witness the scale of the Daleks' power, while Rassilon became increasingly fanatical as he sought to achieve victory, finally turning the War Doctor against him when his plan to destroy a Dalek fleet would have sacrificed countless millions of innocent people, as well as one of Rassilon's agents killing the War Doctor's temporary new companion Cinder ("Engines of War"). Although he was able to destroy the Dalek fleet and save the humans who would have died if Rassilon's plan had succeeded, this evidence of how far his people had fallen left the War Doctor resolved to end the war by any means necessary. As a result, after the fall of Arcadia, Gallifrey's second city, the War Doctor penetrated the Omega Vault - a vault holding the most dangerous weapons the Time Lords had ever encountered or created - and stole the last weapon left; the Moment, a galaxy-destroying weapon so complex that it developed sentience and a conscience, requiring the user to morally justify his use of it ("The Day of The Doctor"). Faced with the continued war between his people and the Daleks, the War Doctor chose to use the Moment, which decreed that The Doctor's punishment would be to survive the destruction so that he could live with what he had done.
  
  With the war having ended with the apparent complete destruction of both sides, The Doctor regenerated once more, so disgusted at what he had done as the 'War Doctor' that he refused to consider that version of himself 'The Doctor', regarding his current body as his ninth incarnation rather than his tenth as it should have been. Although he encountered some Dalek survivors - ranging from a lone Dalek ("Dalek") to the Dalek Emperor ("Bad Wolf/The Parting of the Ways") and the mysterious Cult of Skaro ("Army of Ghosts/Doomsday") -, The Doctor was nevertheless convinced that he was the last of the Time Lords ("The End of the World"). Although the Tenth Doctor discovered another surviving Time Lord who had survived by retreating to the end of the universe and turning himself human via the Chameleon Arch - a device that extracts the Time Lord essence and transfers into a watch, leaving them ordinary humans until the watch is re-opened -, the fact that it was The Master forced him into another desperate battle for the future of humanity as The Master successfully conquered Earth using a telepathic network to trick the human race into voting for him as Prime Minister before The Doctor was able to undo his conquest, culminating in The Master allowing himself to die after he was shot as it was the only way left for him to hurt The Doctor ("The Sound of Drums/Last of the Time Lords"). Despite his death, The Master's minions were able to restore him to life using a complicated ritual some years later, the process was interrupted at a crucial moment, resulting in The Master's new body burning through its energy at an accelerated rate. When access to alien healing technology allowed him to turn the rest of the world into other versions of himself, The Master used the opportunity to track a strange drumming that he had heard in his mind for centuries - now amplified as it was shared by his duplicates - back to its source, learning to his shock that it was from Gallifrey; in the last days of the Time War, in a desperate attempt to escape destruction, the Time Lords had sent the signal into the mind of The Master in the past in order to create an escape route from the Time Lock surrounding the war. Although the plan essentially worked, The Doctor revealed that Rassilon was unconcerned about the fact that coming back into the universe would unleash the horrors of the Time War upon creation and tear the vortex apart, Rassilon intending for the Time Lords to ascend to a level of pure consciousness and live on as the universe died to ensure their survival. Outraged at having being used as the President rejected him as a disease, The Master helped The Doctor break the link that had drawn Gallifrey back to the universe, sacrificing himself in a last, vengeful attack upon Rassilon as the Time Lords faded back into the Time War ("The End of Time").

   Following his regeneration,  the Eleventh Doctor appeared more comfortable in his role as Gallifrey’s last  survivor, having seen what his people would have done and thus allowing him to  reaffirm that he was right to stop them. Despite this, he still carried some  degree of guilt; when he received a telepathic cube message apparently sent by  a Time Lord hiding outside the universe, he immediately went looking for its  source in the hope that the surviving Time Lords would be able to forgive him  for what he had done (The cubes were revealed to be a trap set by the  planet-sized entity House, which sought to eat TARDISes) ("The Doctor's Wife").  Some time later, a new Time  Lord was briefly created when The Doctor’s companions Amy Pond and Rory Williams consummated  their marriage inside the TARDIS, exposure to the Vortex resulting in their  unborn child being infused with the genetic potential of the Time Lords, but  the child was abducted by the mysterious Silence, a religious order that sought  The Doctor’s death to prevent him from answering a question that would  supposedly end the universe. Although The Silence raised the child to become an  assassin against The Doctor, The Doctor’s encounters with her future self of  Professor River Song allowed him to convince the younger River to rebel against  the Silence, River poisoning The Doctor after they finally confronted each  other in her third incarnation (Her first apparently died of an illness while  still a child ("The Impossible Astronaut/Day
    of the Moon") and the  second grew up posing as her parents’ best friend ("Let's
        Kill Hitler")) only to sacrifice her remaining ten regenerations to save him  when her parents convinced him that he was worth it. 
 
  Although he remains the  last Time Lord left in the universe, the Doctor’s perception on Gallifrey’s  destruction was changed forever when he was brought into contact with his tenth  incarnation along with the War Doctor, the War Doctor having been sent into the  future by the Moment to see the men he would become if he made the choice to  destroy Gallifrey ("The Day of The Doctor"). Although the War Doctor  was briefly convinced that his actions were necessary to save billions more,  the future Doctors - inspired by the Eleventh’s companion Clara Oswald - were  able to help him think of another way, the three Doctors subsequently making  contact with Gallifrey High Command to reveal their plan to their fellow Time  Lords; by taking their TARDISes into the upper atmosphere and positioning  themselves at equidistant intervals around the globe, The Doctors would then  freeze Gallifrey and the Time Lords in a single moment in time held in a  parallel pocket universe. Although the Time Lords would be frozen in that  moment with no guarantee of return, the Eleventh Doctor pointed out that this  plan gave them hope that they didn’t have at the moment before he went into  action alongside all twelve of his other selves, the plan having been sent back  to the First Doctor so that he could subconsciously work out the necessary  calculations over the course of his many lives until the ‘Thirteenth’ Doctor  (Considered the Twelfth due to the War Doctor’s actions) could send the  instructions to his younger selves as they put the plan in motion. As the  Daleks increased their firepower, aware that something was happening without  knowing what it was, the Time Lord General gave his permission to attempt the  plan, the subsequent efforts triggering a massive explosion that could have  been either the Daleks destroying Gallifrey or the Daleks blowing themselves up  as they kept firing even after Gallifrey vanished. Although initially uncertain  if they had succeeded, the War Doctor noted that they had at least now failed  attempting to do the right thing rather than succeeding at doing the wrong  thing, the Eleventh Doctor’s subsequent encounter with the museum’s mysterious  Curator (A man resembling an aged version of his fourth incarnation) leaving  him with hope that the plan worked and Gallifrey was still out there somewhere,  prompting him to resolve to find his home one day.

  The Doctor almost  discovered Gallifrey’s location when he discovered the last of the cracks in  the universe ("The Eleventh Hour") created by the TARDIS exploding ("The Pandorica Opens/The
        Big Bang") after tracking a mysterious signal being  broadcast across the universe to the planet Trenzalore, realising that  Gallifrey was on the other side of the crack; the signal was the question  ‘Doctor Who?’, with the Time Lords needing The Doctor to confirm his identity  so that they would know that it was safe to return. However, the signal had  already been detected by various adversaries of The Doctor, including the  Daleks, who had laid siege to the planet and would begin the Time War all over  again if the Time Lords returned. After centuries of conflict - The Doctor  aided by the mysterious Silence that had initially sought his death to ensure  that the Time Lords couldn’t return before the Daleks nearly destroyed them -,  with The Doctor about to die of old age and on his last life as the Daleks’  final ship attacked, his companion Clara Oswald spoke through the crack as The  Doctor prepared to face the Daleks, informing the Time Lords on the other end  that The Doctor didn’t need to reveal his original name as ‘The Doctor’ was all the identity he  needed, subsequently challenging them to help The Doctor. Accepting Clara’s  advice, the Time Lords healed the crack after sending The Doctor enough energy  to start a new regeneration cycle, the energy expended by The Doctor as his  body reset itself proving so powerful that he destroyed the last Dalek ship  left standing with the regenerative energy he released before changing ("The Time of The Doctor").

          Although The Master somehow returned to the real universe - albeit in a female form called Missy - Gallifrey's exact location remained unknown; The Master claimed that it was back in its original coordinates, but when the Twelfth Doctor investigated those coordinates after The Master's apparent death, he found no trace of Gallifrey or his people, leaving him continuing his quest to recover his people with no way of knowing where they would be ("Dark Water/Death in Heaven"). Eventually, The Doctor was returned to Gallifrey after he was trapped in his own confession dial and admitted that he was the subject of the ancient prophecy of a hybrid who would rule Gallifrey, opening a portal back to the planet and learning that it was now located at the end of the universe for its own safety, the Time Lords having somehow escaped from the frozen time that he'd trapped them in ("Heaven Sent/Hell Bent"). Returning to his childhood barn and witnessing some of his old family, The Doctor was soon confronted by Rassilon's forces, but deliberately shunned any attempt to contact him about his return to Gallifrey until Rassilon came to confront him directly, The Doctor provoking him to depart Gallifrey as the other Time Lords sided with him. Although The Doctor temporarily took control of Gallifrey, when questioned about the prophecy of the hybrid, he instead chose to use his power to try and rescue his companion Clara from the moment of her own death despite the risks to the Web of Time, subsequently escaping Gallifrey once again in a different TARDIS as Clara informed the Time Lords that they were still hiding because they were hated by the universe. Despite The Doctor’s efforts to restore Clara’s life by taking her to the end of the end of the universe to 'outrun' the damage her survival might cause, he eventually erased his own memory of Clara in order to prevent them becoming the hybrid who would destroy everything as they pushed each other to greater extremes. However, despite Gallifrey's new secrecy, they have come under attack on two separate occasions, when Rassilon formed an alliance with the remaining Cybermen to try and remake the universe ("Supremacy of the Cybermen") and when The Doctor's old friend Faye suffered a psychological breakdown and tried to destroy the Time Lords before The Doctor was able to help Faye realise she was wrong ("The Clockwise War"). The Doctor was able to convince Rassilon and Faye to halt their attacks, even working with Rassilon to erase the Cybermens' latest actions from history, but these actions reinforced the Time Lords' need to stay secret in this new universe.

          Some time after The Doctor's regeneration into the first female incarnation, the Thirteenth Doctor learned that The Master had destroyed Gallifrey after learning some devastating secret about Gallifrey's history ("Spyfall"). Although The Master refused to share that secret at the time, The Doctor found further confusing details of Gallifrey's history when she encountered a woman in Gloucester who claimed to be another incarnation of The Doctor (despite the fact that neither the new Doctor or the Thirteenth Doctor recognised each other, making it apparently impossible for either of them to be the other's past self) and was confronted by a woman who claimed to be trying to capture the new Doctor on the orders of Gallifrey ("Fugitive of the Judoon"). Later, while trying to protect the last humans of the distant future from the remnants of the Cybermen empire, The Doctor found herself faced with a portal that apparently led straight to Gallifrey, with The Master the last apparent survivor on the planet. Forcing The Doctor to access secret files in the Matrix, The Master revealed that the Time Lords' ability to regenerate was based on analysis of a child who had emerged from a dimensional portal back in the distant past, apparently capable of perpetual regeneration… and The Master claimed that The Doctor was the child in question, with the Time Lords erasing his/her memory at varying stages while also forcing The Doctor to act as an agent on occasion. While The Doctor was able to determine that there were  memories hidden in her mind, she chose to accept them rather than fixate on  the fact that she had been deceived, informing The Master that she considered  herself to now be greater than she had been, using her new memories to overload  the area of the Matrix that The Master had tried to trap her in. The Master  attempted to use the dead bodies of the Time Lords he had previously killed to  form the basis of a new army of Time Lord/Cyberman 'hybrids' that would be  capable of regeneration, but one of The Doctor's allies was able to use a  'death particle' retrieved from the former Cyber-leader to destroy the  'Cyber-Masters' while The Doctor and her allies fled Gallifrey.
