Some version of earth, but not mine. None of this stuff exists where I'm from. We have demons and monsters and all, sure. But this gem stuff is totally new for me. And I saw some giant talking turtles show up here? And a kid I talked to basically comes from a sci fi genre setting.

So as for where it is in the world, who knows? Even a guess based off the local town's population's looks and accents is useless cuz I'd just be applying the standards of my earth to this earth.

To be honest I've spent most of my time hanging out in here hoping the G.F.G. there will finally reveal something useful. Town has given me nothing.
