OOC: Notes on a Master
He did not create the Toclafane, they did it to themselves. And the Utopia signal was there already, perhaps a distress signal from long ago.
He's a ghost. He absorbed the energy of Gallifrey dying and became a sort of mark on the fabric of the universe.
He ate Rassilon, and what was left of Lucy.
He has in his pockets at any time an apple, some slices of ham, three fingers, a few cookies, a slice of cake, a dead rat and some tea bags.
Oh, and a laser screwdriver!
He and his Doctor will live long, die in each others' arms, and go to a Heaven with red grass together. In place of drums there will be the sound of wings, and every days will feel like an adventure.
