At the base of a mountain, someone puts a letter and a small paper wrapped parcel into a mailbox.
"Toril. It's another plane of existence. I've been a professional lost person for years now, when I get lost, I get very lost."
"What does 'another plane of existence' even mean?"
"Uh. Shit, how do I explain the weird shit that doesn't make any sense in a way that makes sense. Um. Okay, so. You have this world, with all of its associated worldly things, like material objects and a coherent magic system and underlying sensible physics, and all of everything is sensibly arranged and self contained and follows one set of rules. Another plane is like - another place, possibly like this one or possibly not, but the rules there might be completely different from the rules here. Geography might change based on the time of day, people might be arranged differently. Or maybe not. There are ways to move between planes of existence, and I have done that. Multiple times. Was that a reasonably clear explanation?"
"Reasonably clear, yeah."
"I apologize on behalf of the multiverse. For the." He waves a hand, awkwardly. "For the weird shit."
"But in your case the weirdness of the multiverse will probably come in handy! ... Though now that I think of it I maybe don't want to set you up with an erinyes, I hesitate to help one get out of Hell without getting to know them pretty well. Devils are the types to sweetly agree to your face and then set your house on fire and eat your soul a year later in a perfectly legitimate and legal fashion. I bet there are other options, though."
"I would be kind of annoyed if you set me up with somebody who set my castle on fire and - ate my soul? I'm not even sure that's a thing but it sounds pretty annoying."
"From what I've heard it's not pleasant. I don't know if it would work on you, I'm not really an expert in soul related things and hesitate to make claims about another plane of existence. But yes. Ideally it would be something everyone could walk away happy from."
"What even is a soul?"
"It's... well, where I come from, it's sort of. The bit of someone that contains everything they are? What would be left if all of the non-essential parts of a person got stripped away, and all that was left was the central essence of the person and who they are. The part that's above someone's squishy breakable body. On my plane of existence, when someone dies, the soul goes to an afterlife if nothing else has any sort of claim on it. But again, I don't know how things work here, you might not apply."
"Yeah, we don't have anything like that, I would've noticed when I was building my immortality," he says.
"I think even if you don't naturally have a soul, you should still avoid signing any contracts with devils to hand one over. It's the sort of thing that would probably backfire horribly in some way. But I'm digressing a little."
"A little, yeah. Seems like useful advice, though."
"Thanks, I try. That time in Hell was not time wasted. Anyway. Can you see yourself being happy with someone that would be more than happy to be tortured...?"
"I'd be happy to be introduced. Can't promise I'd devote myself to them forever or anything."
"Sure. But I'd like to find a solution that works for everyone that doesn't involve, uh. People getting kidnapped and tortured."
"You might end up disappointed."
"I might," he agrees. "But I'll definitely be disappointed if I don't try."
"Eh, fair enough."
"So does your ideal situation look like this? With the kidnapping and the torture and the mountain that'll explode if you stop. Or are there things you wish you had in your life that your lifestyle might be inhibiting?"
"I'm not delighted about the mountain that'll explode if I stop. I've been working on it."
"Any way I can help with that? It seems like it'd help if you were under less pressure to torture people, at the very least."
"You probably can't do much for it, but I don't know a thing about your otherworldly magic so maybe there's something."
"I'm mostly not a master of otherworldly magic. Just a guy that's good at handling weird situations, finding things, and staying alive. What sorts of things would be helpful?"
