Yep, for sure. I don't know if I truly "believe" in any of it but it's a fun "what if?" sort of thing. It's sort of an exercise in imagination and creativity, as well. I'm writing a roguelike with lore vaguely based on the idea of alternate planes/realms/etc, and while roguelikes aren't known for their heavy story it's still helped give me inspiration for coming up with the lore.
