This universe has a civilization of humans! And some other things. It's not crowded in the way Edda is but it's not just the one planet either. The humans might be easiest to start with. They're on that planet over there, it's not Earth but it has very Earthlike conditions and bronze-age humans living in cities and villages dotted across two large continents. Depending on how thoroughly any prospective visitors look they might find other things before visiting.
"- well, I can see it..." This psion hasn't learned to do illusions, unfortunately. "It looks - new? I think maybe for best results here you want to get an Ainu in to see if they can call her original soul over. Wishing might do it too. I think I could make this more comfortable but I don't have the original material to work with."
"The original is what I'm missing. The pain is almost completely gone and I've proven to myself I can still be creative," Nod towards the painting, "But all my memories kind of seem like some stranger's memories right now. If you say - a god - might help me, you're more of an expert on this than me. Thank you."
"All this appearing and disappearing all the time, instead of walking places," she snorts. Turns back to her canvas and starts cleaning the brushes, since her guide is probably taking her to yet another place soon.
She smiles lopsidedly. "Just me at first, so I'm the only one who gets burned if it wishes badly?"
"I wouldn't mind if it might make things worse. Someone has to be the first into the fire. I'm getting a second chance. Why shouldn't everyone else, yeah?"
She finishes tidying the art stuff.
Sai Ding sends another message, and another person comes in to witness Sai Ding explaining the parameters of Mîr wishing (that it leans on your emotions, that you only get one, that this makes it impossible to become a magic rock which requires a separate screening process, etcetera) so they'll take up a minimum of Gem's time.
"-Being a magic rock sounds ridiculously awesome, though, stars, magic costumes and all," she says after receiving a bit more explanation on that. "I'm not actively miserable right now, I'm more just - couldn't go home like this - what is the screening process?"
"- it's kind of time consuming and I was assuming you were in more of a hurry," says Sai Ding. "I don't actually know what the process is, it's a Mîr thing more than a Vanda Nossëo thing - do you know -" she asks the witness.
"I haven't taken the prep course yet," says the witness, shaking his head. "It's not supposed to be super hard to get if you aren't inclined to commit crimes or blatantly ignore safety instructions though."
"I'm in a hurry for them, the people awaiting my return. The artist's return from the dead is- It's a story, right? Half the people paying in to bring me back were probably doing it to be part of that story, the city uniting to return one of its beloved. But staying away to pass a magic empress's test and make a wish and gain magic power is an even better one. They'll name a new festival after me. Or her."
"Well, if you want to enroll in the prep course I can sign you up," says the witness. "Name, Samara Glory - world, I think the working title for it is Spirit but does the computer system - cool, that gets me the ID number - do you require a scholarship for the course or will you be paying your tuition fees -"
"Hah, sorry for the confusion, Sai Ding, right? But the narrative is important, I'd feel terrible if I just up and never went back, or I'd be fine to wander off somewhere with basic income right now. Uh, I haven't exactly got a lot of money on me." She smiles and shrugs. "Betcha someone back home will pay a bunch for this once I've put a few more hours into it, though," she indicates the painting. "Maybe offer a loan against future work too."
"I haven't got any other places to be if someone will take a message back to Sunsea City that I'm on a quest."
