Here is a fairy. With proper fairy wings and all.

"Hello, summoner. What do you need moved today?"

Temple drops the piece of chalk he was using to draw.

"Dude, not funny, this is private property... And butterfly wings? Seriously?"

"...Um. Your circle summoned me? By all means, dismiss me if it was an accident. Happens to the best of us."

Temple looks at him quizzically.

"Okay, I was going to just kick you out, but since you are keeping up with the joke, please tell me how to make wings? It is a nice exchange for interrupting my rune work."

"It's a certain potion, I don't have one on me and I'm not sure it'll even work on non-daeva, let alone safely. And I'm pretty sure there's some deeper misunderstanding going on here. I've never heard of any sort of magic involving runes. I can move some things if you'd like proof."

"Are you from a distant part of Elsewhere?" His irritation quickly melts away, leaving only curiosity behind. "What is a daeva? What principles your schools of magic follow that don't use runes?"

"A daeva is a kind of person who can do magic. Our, school, as it is, is summoning. Humans summon daeva and make deals, a daeva's services in exchange for whatever. Your rune circle has apparently masqueraded as a summoning circle, so I got to visit a new universe. Lucky me."

Temple looks suspicilously at the rune circe bellow him.

"Lucky me. What kind of deals daevas make? Should I be worried for my immortal soul?"

"If you had summoned a maker, maybe, but I'm just a fairy. I usually ask for food, clothes, tools, that kind of thing. And this terrible circle isn't strong enough to hold me to a deal, anyway."

"In my defense, I wasn't trying to do anything even close to a summon, this is a protection spell. An awesome protection spell of my own design."

"Oh? Well, I suggest you modify it at least slightly before writing it out again. Unfortunately, this exact configuration of runes summons a random fairy. Lucky you, you got a friendly and professional one and not some random jerk."

"Really? At least few people are willing to combine reformed and traditional Hermetic-Parker runes in a... At least people aren't likely to try this spell design" Temple sighs, so much research lost, he raises a hand.

A tiny cloud condenses and starts raining, melting the chalk away.

"So what else can you tell me about your kind of magic?"

"If you rearranged a few things it might work, just saying... I don't want to lay out summoning for you until I'm positive you'll be really damn careful with it, evil daeva are hideously dangerous. Fairies move things with a maximum size of approximately 'large hill' and a maximum speed of 'the speed of light'. There's two more kinds, one changes things. Like stone to metal, or a broken bone to a fixed one, or the reverse of that. The last makes things, from acid to bombs to worse but also food and medicine if you can convince them."

"I couldn't, the magic requires that specific layout. Being careful is reasonable, are daeva likely to be jerks?"

"Nnnot really. All three kinds of daeva are just people, and it turns out that once in a while people are jerks. And when you can make just about anything you want, the only reason to take summons is for things you can't just make. Like souls, or sex, or if you're lucky new stories, or if you're very lucky, altruism."

"And is only one thing per... race? Species? Do you spend lifeforce or something else while using your powers?"

The small cloud stops and localized wind helps the water to drain away.

"Species. And no, we can do it at our maximum all day and not feel any different than if we didn't use it at all."

Temple stares at him, then he stares back towards the city beyond the deep chasm.

"Sink. I mean, we really need to have that thing sunk." He points towards the city.

The city is vast, made of stone buildings and goes all the way to the horizon taking over all that side of the deep and wide chasm that separate two sides.

On this side, there is a small rural-looking village surrounded by a tall agressively green forest, the sky and filled with an absurdity of stars.

On the other side there is the city and nothing else, no people, no sound, even the sky above is completely black and now that Nick is paying attention to it, he can definitely feel a sense of uneasy just by looking at it that can't be just his imagination.

"Uh huh. That looks like a city. People live in cities. I invite you to convince me this is wrong for that particular city and that it ought to be destroyed."

"Fair enough. No one lives there, that city is an horrible example of magic going wrong, it drains ambient lifeforce... it doesn't hurt to just stand there, but you can't heal, you can't sleep, nothing grows and the damn thing spreads like an infection and so far the only way to stop it is by cutting all the way through the bottom of the world."

"The... Bottom? This is a new thing for worlds to have, to me."

"Oh, yes. This world is basically a layer of rock, usually two miles thick. Atmosphere, gravity and light are done magically. The dead city subverts that magic into that."

"Sounds nasty, for sure. I hope you don't blame me if I check your claims by visiting. And do you mind telling me what else your magic can do?"

"Sure. It isn't that urgent actually, that was mostly my shocked reaction because having any kind of easy solution to the problem was... new." He sighs. "My magic is based on spending lifeforce, of which there are five sub-components. It can do moving, changing and creating things, not necessarily easy. It also can do healing, limited shapeshifting, teleportation, control over different kinds of energy, control over plants or animals... powers that influence the mind are rare but exist.. multiple kinds of protection and senses. Basically that."

"Are the effects permanent? Can you make a new kind of plant? Because if so, I want that as pay for removing the city-cancer."
