"Every world's a little different," Soda said, looking up. "I dunno what my world's one is like, if it has one, since, y'know, lockout and all that. If it doesn't, then the spirits drift in the Overworld until they find another reality to live in. Worlds that don't have an afterlife basically treat every death as a lockout. Worlds without a creator--because they left or they're spontaneous or whatever--work that way, I think.
"Cibus, I dunno. Looks like it's the celestial plane. Not sure why Pokemon like Sunny over in Treasure Town have access to it, but it's kinda a between thing the Overworld set up. Easy access to a lot of people if you just think to find 'em. And they're accessible, and still those people. Which is kinda weird, because Cibus seems pretty much independent from Overseers, like most worlds..." Soda paused, like that thought had him on a mental tangent. "...Oh right. Truffle's world is kinda fucked, since his operates on reincarnation. So anybody who dies there gets recycled into a new life with their past lives' memories sealed. Then there's Flesh, who was a spontaneous creation in an Ultra Pocket. They fall under that first category I mentioned.
"As for what the gloomy light dragon said, yeah. Some worlds have entities or gods that decide it's pretty nifty to make punishment dimensions. Or they're just entities that trap the dead. That's also fucked. Overseers, when they catch wind of something like that, they usually step in and put a stop to it. Process can take anywhere from days to eons, though, depending on shit like scope and divine cooperativeness." Soda tapped his claws. "I punched a devil once. That was pretty cool."
