The rock that could not be lifted by human or genie continues hauling itself upward into the void, carrying a wooden sign saying "Don't make vague wishes!" in white paint.
Bit late for that.
Exfoliated reality sheds off dead outcomes, and you wake up in the park next to a large boulder and a very confused...is that the genie from earlier? She looks slightly more human, her skin and eyes and something about her facial structure resembling yours with a bluish tint.
You look down, and you seem slightly more genie, what with the bluish skin tint. You look up, and see the opening sequence of a show named "Impossibly Possible" is playing on a sky, slowly turning more blue from the black it was earlier. A flock of birds shaped like a tree is nailing a progress bar to the sky, shooing away glitches and the occasional confusing metaphysical construct expressed as tangibly surreal memes.
"So, uh." the woman of the lamp says. "You know how I said I wouldn't be able to grant vague wishes? That's what happens if I try to fill in the blanks myself but create a logic error. Logic breaks and rewrites reality until it can find the erratic parts of the magic and shed off the dead bits of possible interpretations. But it autocorrects pretty wide, and it looks like the bestfit decided to fuse humans and genies into something new instead of just say 'any means is dumb'. Look, we're all this weird new thing called 'jinn' now. They used to be made when people hybridized humans and genies as a type of witch. But now, basically everyone who was a normal human or normal genie is one. A lot of animals and magic objects are too, but it's not as global, mostly pets and stuff stemming from weird wishes. I checked all the phenomenal cosmic power department and I still have it, but now you can catch up instead of having it from birth or making a wish. Did you notice electricity is my son now? Like the whole thing's an elemental with more kids."
You stand up, then realize you can float into the air. Reality seems to be more dreamlike or as a bunch of changeable words, bending to your will as you conjure a bunch of gratuitous magical sparkles and random household objects. A few buggy hologram-style glitches are still embedded in the landscape, and sometimes something dramatically changes appearance, but the people treat this as an everyday occurrence, sigh, and wish the problem things into something else to fix it piece by piece. You abstractly sense an immensely powerful aura from the ex-genie, a ridiculous logical law that looked very patched-together from the rock, and so much more complicated underlying reality and text that you...
"A sitcom!?" you say, stretching your power toward the dome of the sky and witnessing the mostly-through musical number between the birds and the boundary of a conventional atmosphere with a spiritual concept of 'sky'. "We're in a sitcom!?"
"Hey, you broke logic, you pay the price." the ex-genie now-jinn of possible and impossible says, tactically ignoring the fact that technically she granted the dumb wishes instead of saying 'narrate better'. "So, we're gonna get in a fancy dramedy thing about magic people, but we've got to pick roles."
The rock is suddenly hovering next to you, holding a new sign that says "I call being the quirky next-door neighbor."
"The rock's magic now," the impossijinn comments as if that's totally normal, "just go along with it until someone rocks the boat and wishes things different. What do you wanna be? I'll probably live with you while you figure out your remaining wish and get used to all that constantly growing magical power thing."
You create a mirror next to you and look at your reflection, deciding you'll be...
