Prologue:
I am the Doctor. I'm a one thousand year old time lord from Gallifrey, the planet that time forgot and I'm about to die. Again. After absorbing the energy of the time vortex to save the many occupants of Earth, I stumble towards my almighty ship; the TARDIS. The doors are locked, but only for a few pain filled moments. I collapse onto the door to my home, to my sanctuary, and I reach into my pocket. I pull out a small, glowing key on a piece of string that would fit into a Yale lock. The inside of me is burning. Slowly, and ever more painfully. Every cell in my body is dying, being burnt out of existence without the slightest sign of remorse.
I place the key into the lock, with a slightly glowing hand, and weakly turn it. Then, I force myself to push open the door to the world within the police box, my world within the police box. I turn, and see the world that would never be seen through this pair of eyes again. Not ever again. With a half-hearted heave, I make it through the door, closing it behind me, and pulling the lock so that it would not be able to be opened from the world outside. I place the key back into my pocket.
I stare at the console of my mighty machine. A corridor heads in one direction, and a distant stairway to the other. Almost keeling over, I slowly, but surely, stumble my way up the metal ramp that heads towards the main console of my TARDIS; the safest part of my whole ship. I flick a switch, press a button, then pull a leaver, clutching my sides as I do. The groans and wheezes begin, and the lights in the centre of the TARDIS spring into life. From outside, all that would be seen is the slowly evaporating silhouette of an old, blue police box.
As my machine rocks from one side to the other, I notice that my hands glow even brighter. I begin to step to another part of the console, and I pull a separate lever, and two buttons at the same time. As the TARDIS floats through time and space, my hands and face begin to glow even brighter, until my whole body is in even sharper and deeper agony. I take one step back from my TARDIS console.
A single tear falls from each of my eyes as the emotion builds even larger inside of me. I begin to look up into the air. Then, light bursts out from my hands. Both my hands are made to be stretched out to my sides. My face is pointing further upwards. I know what is happening to me, an old trick of my species, the Time Lords. I am regenerating! My hands crack, burn and change. My nose, eyes, mouth all appear to melt and form all new, all distinctive and all different features. I shriek in agony.
Then, it's all over. After it all ends, I find myself facing forwards. I have shrunk so my clothes are too big for me. Tripping over my now too long trousers, I accidentally fall onto the TARDIS console, hitting a few buttons in the process. An awful, gut wrenching noise rings throughout the console of the TARDIS. The once turquoise light emitting from its centre becomes a blood shot red.
"Oh no, I'm sorry, I'm so sorry. I didn't mean to do that!" I say to myself, running around the console, hitting buttons and pulling levers into sequence, trying to right my wrong.
"Come on old girl! Don't fail on me now!" I almost begged my grand machine. But it's no use. Before I know it's even happened, she falls and crash lands somewhere, yet I have no idea as to where or even when she has fallen to.
So, I'm the Doctor. I'm a one thousand year old time lord from the planet Gallifrey. I'm the person that has saved Earth from near destruction countless times before. And I'm about to tell you an adventure that brought such great joy, but equally, it brought such terrible sorrow.
