I push open the battered blue doors of my TARDIS into a different dimension. I activate the Vortex Loop, then the Dimensional Stabilisers, and finally the Vector Tracker. The control room shudders, but I'm used to this. I've been on this stupid planet for far too long now. I live to explore.
I am the Doctor.
The universe was so happy. Once upon a time, I used to have the pleasure of taking humans on as my companions and taking them to the furthest reaches of the universe. It was fun while it lasted, but then I realised, on that fateful day that Rose died, that humans don't live forever. I cannot return to my race, as they are dead too. Everything is gone eventually. Except me, and my constant companion. Death.
The TARDIS' ancient engines begin to fade away, and I arrive at my destination. My destination is unknown; I simply wanted to get away from Raxacoricofallapatorius as soon as possible. So I step outside the doors, right into a robot.
I can quickly tell that this is either a security or an assassination robot. It's a humanoid, and a little taller than me, made entirely of metal. It has a thin visor on the steel 'head' with a reddish glow pulsing out. Two long arms carry many different kinds of weapons, all pointing at me. I slowly put my hands up.
"State your name," the machine says in a surprisingly human voice.
"I'm the Doctor."
"You will come with me." As I step forwards, the machine's cold hand grasps mine and places a primitive handcuff on my wrist. It takes me through this long hallway. I've been in this sort of place before – control panels on the wall, mechanical lights on the ceiling, a glowing red walkway beneath, no form of decoration whatsoever. My guess is that it's some kind of 'home for metal'. The security guard and I reach a metal doorway. And that's when I strike.
