For a millennia, a thousand years, he's been my pilot, my friend, my companion. Through time, through space, even other dimensions, we've been together. We'd survived - for so long we survived. The Last Great Time War was finally ended, finally won, by an old rogue and his even older ship. The Daleks are gone, the last one exterminated by my pilot's own hand, at the end of himself.
Can a ship cry? Can a ship actually FEEL? I don't know about the former, but the answer to the second question is a definitive YES. Every centimetre of my expansive interior, out to the wooden panel of my wooden police box exterior, aches. I'm dying, I know it. Without the Doctor, my pilot, I'm lost.
The Doctor, last of the great Time Lords, last member of Gallifrey, is gone... The people who created me, so long ago - two thousand some years past - are completely extinct. And I'm the last of my kind, for now. The Time Lords created us, the TARDISes, living ships capable of traversing through space and time, to oversee the stability of the Universe. It takes centuries for a TARDIS to grow from the tiny Coral we start as. Few species other than the long-lived Gallifreyans have the life span to grow us, so of the few of my kind that existed after the War, only I am complete.
I know of one other, that MAY, in time, come to completion. My, for want of a better word, daughter. A piece of Coral taken from me, is being grown by a true immortal, a man who cannot die. Perhaps, after I Fade, she will complete and carry on.
I don't want to Fade, to die. But what can I do? I lost my pilot; and with him, my purpose. Back before the War, and the extinction of my Creators, I could gather the energy I needed to survive from the Eye of Harmony. But it's gone now destroyed with those who mastered it. And now, my pilot - who leant me the energy I needed after - he's gone, too. For a time, I can derive my energy from the Universe itself; but without a pilot, I don't know how long even that will last.
Even now, my systems are failing; slowly to be sure, but it's happening. I can feel myself slipping away, to join my pilot and his people in oblivion.
