The Survivor, gaining her name after she stopped an assassination attempt, was born into High Gallifreyan society, treated like a princess, but gave it up to marry the Doctor and run through time and space with him.
After they were seperated during the Time War, her eighth incarnation died at the edge of Gallifrey's destruction and regenerated into an infant. She left a note to the Doctor to turn her into a human and hide her on Earth. There, in 1986 London, a nurse on her first day accidentally switched her with another baby girl. She was taken in by Pete and Jacqueline Tyler and christened Rose Marion Tyler.
Nineteen years later, Rose is blissfully unaware of her Time Lady lineage, which is known only in her dreams, until that day in the basement of the department store when the Doctor grabs her hand and whispers, "Run."
With the TARDIS seemingly calling to her, she joins up with the Doctor and begins to solve the mystery of her past... but it seems to be a locket that had been with her since she was born that could solve it for her.
Is the Survivor alive or dead? Who knows?
EEEEEEEEEE! I'm so excited for this one too! This has been in my head of a while and I have so many ideas for this series, along with some new characters. And even if Rose is staying after Doomsday, I'll let you know it won't be any less emotional.
