Okay, so I'm not exactly immortal, but to a race as short-lived as the humans, it's practically the same thing. What I AM is genetically altered; altered by time itself with the help of a rather clever sentient machine.
It all started with a man called the Doctor. He saved my life, and with one word altered my destiny forever. "Run", I can still hear him saying that to me, taking my hand and running with me out of that shop. Then watching it explode. But the Doctor, he's not human, he looks like one, but he's not. He's a Time Lord, the last of his race actually. A being that could travel through time and space in his living ship: the TARDIS.
We had quite a few adventures, saving people, planets, even the galaxy a couple of times, until we were captured.
We were caught by the Doctor's most hated enemy, the Daleks. The Doctor tricked me into going home, knowing that I would never voluntarily leave him. He wanted to save my life, not that it actually worked. I couldn't leave him there to die alone at the hands of an enemy he lost his entire planet to. I opened the heart of the TARDIS and looked into the Time Vortex. The vortex entered my mind, and that's when it all began to change.
