Elizabeth Harper

"I'm Lizzie Harper, also known as The Author and I'm a Time Lady from the planet Gallifrey in the constellation of Kasterborous, I am 902.... And I am in love with The Doctor,"

Before she was Lizzie Harper, she was The Author.
She used the Chameleon Arch to hide herself from the Daleks and the Time War, but she eventually finds her Doctor on planet earth.

(DISCLAIMER!! I don't own doctor who or the characters, I only own Lizzie and I read someone do something like this and got some inspiration)
