"Gods aren't in the universes; they're outside the universes in the supernatural realm. Places we've heard about or read about in books--Gladsheim, Elysium, Hades, Pandemonium, Limbo, the Abyss, the Seven Heavens, the Nine Hells--these are all supernatural realms along the edge of the deep supernatural. The Architect says that you can't enter the deep supernatural and return, but several versers have been on the border supernatural at one time or another. Adams says that they were just in different worlds, where creatures with the power to travel interdimensionally at will pose as gods, but he's never been to one. Anyway, the point is, all the gods have the same ability to act in any universe. Some have a sort of ascendancy in some--like you might be in a world where Zeus and his cronies are in charge, but that doesn't mean that Odin and Thor can't answer prayers there, it just means that Zeus makes the ground rules. Gods have to abide by their own ground rules; what Zeus allows himself and his cronies to do, the other gods can do, too. How it got this way--well, if you meet the Architect, you can ask him his theory; I don't have one."
When you suggest that him killing you would be a good thing, he grins in a very disconcerting way. "You're afraid of that volcano, but not of me? I assure you, I am much more dangerous than that volcano.
"If you're worried about losing your things, don't. If I'm right, when this happens it will happen so fast that your things will all go with you. Anyway, there aren't very many things in the multiverse that are irreplaceable. You'd have a hard time finding more than a dozen copies of the Necronomicon--and indeed, I saw Aslan destroy one, so that's one less, durnedest thing, I'd tried ground zero at a nuclear blast and didn't singe the cover, and he tapped it with his front paw and it disintegrated to dust. I knew I was dealing with someone powerful at that moment. But I doubt you've got anything so unique as that. Maybe if you've got pictures of family or friends, or some object that is special not for what it is but because someone gave it to you, those would be things to protect. But you'll lose some things sometimes--you just won't lose them by dying. Contrary to the popular saying, you can take it with you.
"Have you ever used a sword? Have you ever used any weapon at all? You'll do best to work with what you know rather than start from scratch, but if you don't know anything, then I guess we start from scratch."
