I walked away from the last Great Time War. I marked the passing of the Time Lords. I saw the birth of the universe and I watched as time ran out, moment by moment, until nothing remained — no time, no space, just me. I walked in universes where the laws of physics were devised by the mind of a mad man. And I’ve watched universes freeze, and creation burn — I have seen things you wouldn’t believe, and I have lost things you will never understand — and I know things. Secrets that must never be told. Knowledge that must never be spoken.
