I guess so. Historically, it was pretty popular among adventurers because it used to sort of randomly get new places to explore, so it was like an eternal source of treasures, or something. Nowadays we mostly just find the scraps of other worlds. It's hard to describe.

Hmm? I'd say around the same time? I suppose technically it's not the first time I've found myself on a whole new world, but the last time that happened was so long ago I barely remember it anyway.
