When I was a little girl, I had an imaginary friend. Her name was Amelia Pond. And when I grew up, I stole a TARDIS and ran away. I never ran away from things, I ran towards them. The universe was always creating and destroying, scattering and pulling together, so it was very possible that my Amelia Pond was out there, somewhere, waiting for an imaginary friend.

Turns out, I was too late.

She already had her imaginary friend, my old friend, the Doctor.

I remember when me and him were young, taken to stare into the Untempered Scism.

The Doctor ran.

I was captivated by it's beauty, inspired by it.

When the Time War came, I was one of the chief strategists. I was allowed to steal fallen Time Lord's remaining regenerations for my own, and because of this, I could live forever and ever, wallowing in my own self pity.

I helped the Doctor kill the Time Lords. I helped him set off the Moment, and then we each took our own TARDIS and ran far, far away.

When I went looking for Amelia, I had one specific goal: make her childhood awesome.

Unfortunately for me and my TARDIS, I had just regenerated and she reset herself. Type forty TARDIS, just breaking her in, and crashed into a hospital while a raggedy man battled with Prisoner Zero.

And it is here that we begin our story.
