If you need a tour guide, let me know. I've been to most places, enough to know that you'll probably need to sit down a bit when you get to Tomorrow. As to your questions, I would say . . . they've all got complicated answers. But there is something similar to magic where I come from, yes, and I'd be happy to tell you about my world if you tell me about yours first, just so I don't repeat myself.

. . . Or someone else.
