Four surviving elementals The four surviving elementals were the only four Time Lord s left after the destruction of Gallifrey and the end of the War . ( PROSE : " The Adventuress of Henrietta Street " , " Trading Futures " , " The Gallifrey Chronicles " ) They ruled all of time and space near the end of the universe as the Imperial Family . ( PROSE : " Father Time " , COMIC : " Miranda " ) Biology . Despite resembling ordinary people , the survivors had genetic privileges that set them apart from all other life in the universe . They were each born with two hearts , and Ferran believed that their blood was continually twisting and reforming . This birthright gave them great gifts . ( PROSE : " Father Time " ) However , living in a universe without Gallifrey had its consequences . The second heart of a Time Lord provided a link between them and their homeplanet , but with said homeplanet no longer existing , their second hearts became poison . The Doctor ' s second heart pushed him to the brink of death before he was cured when Sabbath removed the second heart and planted it within himself . ( PROSE : " The Adventuress of Henrietta Street " ) The Doctor was able to adapt to having only one heart . ( PROSE : " Hope " ) Chloe and Erasmus similarly had to remove their second hearts after they began to wither after the War . ( PROSE : " Timeless " ) The four . A great number of sources agree that the Eighth Doctor was one of the Time Lords to survive the War . ( PROSE : " The Adventuress of Henrietta Street " et al ) Due in large part to the fact that the Matrix was downloaded into his brain , ( PROSE : " The Gallifrey Chronicles " ) the Eighth Doctor had very few memories of his life before the end of the War . He and his damaged TARDIS were deposited on Earth in the late 19th century by Compassion . ( PROSE : " The Ancestor Cell " ) After living on the planet for over a century , the Doctor regained use of his TARDIS ( PROSE : " Escape Velocity " ) and travelled through time and space with Fitz Kreiner , Anji Kapoor , ( PROSE : " Earthworld " et al ) and later Trix MacMillan . ( PROSE : " Timeless " et al ) The Man with the Rosette was another one of the four elementals . He believed that since there were only four of his people remaining , he had to maintain " certain standards " . While once a bitter enemy of the Doctor , the Man with the Rosette remained amicable with the Doctor in the post - War universe . ( PROSE : " The Adventuress of Henrietta Street " ) Near the end of the universe , the Emperor - the greatest of the elementals - ruled the universe from the Needle , ( COMIC : " Miranda " ) which was itself another remnant of the Time Lords : Savar ' s TARDIS . ( PROSE : " The Infinity Doctors " ) The Emperor was the last of his kind , having outlived all of the other Time Lords . Shortly after the birth of his daughter , Miranda , the Emperor was assassinated . ( PROSE : " Father Time " ) When the Doctor saw himself in his vision of the four survivors , he was seated on an ornate throne and holding baby Miranda , suggesting that he was to become the Emperor . ( PROSE : " The Gallifrey Chronicles " ) The Onihr claimed to have learned the identities of all four surviving elementals . ( PROSE : " Trading Futures " ) Other possibilities . Iris Wildthyme encountered the Eighth Doctor at least twice in the post - War universe , once in her Jane Fonda incarnation ( PROSE : " Father Time " ) and once in her Brenda Soobie incarnation . After his encounter with Brenda , the Doctor proclaimed , " But this means . . . I am not alone ! " To which Fitz somewhat jokingly replied , " There is . . . another . " ( PROSE : " Mad Dogs and Englishmen " ) However , the Fonda Iris , ( PROSE : " The Blue Angel " , " Interference " ) the Brenda Soobie Iris , ( PROSE : " The Blue Angel " ) and even some of the later Irises ( PROSE : " Library Pictures " , " A Hundred Words from a Civil War " , " Michael Drake " ) had some involvement with the War , indicating that Iris was not a definite resident of the post - War universe . Iris also said several times that she was not a Time Lord , meaning she wouldn ' t qualify to be one of the four surviving elementals . ( PROSE : " The Blue Angel " , AUDIO : " The Elixir of Doom " et al ) Iris was once hunted down by Herr Drosselmeyr because she was one of the last of her kind . ( PROSE : " Another Clockwork Iris " ) Romana III lived on for many centuries after her final encounter with the Doctor . As an ancient woman , she parked her TARDIS in Janua Foris and told some of its natives the story of her encounter with Valdemar . After telling the story , Romana regenerated into a young , beautiful body with dark eyes and clear ebony skin . ( PROSE : " Tomb of Valdemar " ) After her father ' s assassination , Miranda was sent back in time to an earlier period of history , where she was adopted by the Eighth Doctor . As she grew up , Miranda exhibited many Time Lord attributes . ( PROSE : " Father Time " ) Miranda eventually returned to her father ' s era to become the new ruler of the universe . ( PROSE : " Father Time " , COMIC : " Miranda " ) She later died during the Eighth Doctor ' s encounter with the Council of Eight . ( PROSE : " Sometime Never . . . " ) The Doctor ' s vision of the four elementals included baby Miranda in his arms , suggesting that she was not one of the four . ( PROSE : " The Gallifrey Chronicles " ) Marnal was stuck on Earth as an amnesiac during the War , and he survived it in this way , unaware of his true nature . The Eighth Doctor identified him as the fifth survivor . ( PROSE : " The Gallifrey Chronicles " ) When she left Gallifrey after its destruction , Compassion carried with her the Gallifreyan technician Nivet . ( PROSE : " The Ancestor Cell " ) However , Compassion was significantly involved in the War even after Gallifrey ' s destruction , so her ( and Nivet ) were not definite residents of the post - War universe . ( PROSE : " The Book of the War " , " Of the City of the Saved . . . " , " Warring States " ) Chloe and Erasmus were also Time Lords who survived the destruction of Gallifrey in the War . They told the Eighth Doctor that they had met many other fellow survivors . ( PROSE : " Timeless " ) History . According to Prefect Ferran , after the War left most of space and time broken and dead , the Imperial Family subjugated the survivors for two thousand years . They grew corrupt with power , and millions of their subjects , who they viewed as lesser species , died from their neglect , cruelty , or sport . The Senate was powerless , and the Senators fought among themselves for scraps of power and wealth , but through secret meetings , they began to form alliances with each other , and a revolution began when the Emperor ' s forces murdered the insurrection leader in the street . After a short and brutal civil war , the Imperial Family was wiped out , with the exception of the Emperor ' s daughter , who escaped back in time and was adopted by the Eighth Doctor .
