I don't know if I'm gonna name this universe - I don't know what to call it, other than mine, since it's sort of in-canon, after-canon. Hookworld? Nah.... (Although that does remind me a bit of "Spiceworld," so hmmmm...)

Thanks too for the generous praise - you've got me pegged on the Narnia reference, as I loved those books as a kid, and one of the things I love about the Buffyverse is the way it can incorporate pretty much any sci-fi or fantasy element, as long as you deploy it in a way that makes sense for the characters. A pocket dimension is just as acceptable as witchcraft and raising the dead, I figure...
