Prologue-

"You know me, you've known me, and you will know me. I am known by many names, by many different faces. Once I was an old, white-haired Scotsman; another time I was a childish bow-tie wearing brown hair; another time I was a short-haired blonde female with a fam. Now I am a younger girl with black hair, fair skin and blue-gold eyes; I journey around with my TARDIS, that is Time and Relative Dimensions in Space.

I am the fifteenth regenerated form. I used to work for UNIT than Torchwood. My fourteenth regeneration got Chameleon Watch-locked; I only remembered who I was after regenerating.

Now that you know my past, let's get to my present."
