Temple is good enough at body language (and basic politiness) to figure out that Nick doesn't want someone reading over their shoulder. He is busy casting with the invisible-ink spell. This one actually involves speaking in broken latin and making complicated gestures. The ink changes by the end of it.

Nick can't help but think they he only has Temple's word the ink will stay invisible. But mistrust is impolite, and he seems sensible enough.

"Right, I'll draw the diagrams and mark out a spot for you to complete the circle. Don't say 'yeah' or 'okay' in front of anyone you've summoned until you're done negotiating, they can take it as acceptance of a deal. For a big job like this most fairies will probably want something significant. Either a lot of food, a nice decoration, or some kind of electronics. But your laptop is unlikely to interest them, so the first two will have to be it."

"I will be careful. And I can get a literal truckload of food in less than a day."

"A literal truckload of food will probably do it."

"Perfect. Lets get started."

"You'll probably want a down payment on top of your literal truck for later, coffee, teas, cookies are old stand-bys. I'll go prepare the circle."

Temple gets the down payment, he lives alone but it is a sizeable quantity of assorted snacks and beverages. The summoning can begin.

There is a little spot marked out for Temple to draw in the invisible ink. "Remember, don't agree to anything until you're done negotiating. They won't be able to use their powers destructively until the deal to destroy things is in effect, I chose an elegantly minimal but still safe binding."

Temple nods solemnly and then he draws with the invisible ink.

And another fairy appears. This one is an asian-looking woman with incongruously blonde hair, dressed in what looks like leaves. It does seem well-made, just aesthetically odd. "Summoner." She glances at Nick and asks hopefully, "Big job?"

"Very big job, but simple. This world is flat and two miles thick, there is a part of it that is magically infected with a cursed city. I need to sink the infected parts."

Temple might be trying to get a reaction.

"...This isn't Earth?"

"Nope. I did some math and it'll take, mm, about 800 fairy-hours in total."

"Huh, this is new. Alright, I'm probably in. What're you paying, Summoner?"

"My name is Temple. Payment in food, I can get you a lot of it. And I'm open to other forms of payment including casting a spell."

"...You two had better not be having me on."

Temple raises his hands theatrically and a small cloud forms between them, tiny lighting sparks inside it.

"That could be a weather machine, I dunno tech... But whatever, I'll play along for one kilo of tea, good stuff, chai or something, per hour. Or a few kilos of other stuff. I prefer to work in no more than six hour shifts. Would you like me to begin immediately, summoner?"

"What do you think, Nick?"

"Okay, so. The job is to sink parts of the dead city for six hours starting when I show you the place, you get your food at the end. I'll show you the place then come back and help Temple summon more of us. What's your name?"

"Kara-xie. That would be acceptable. Summoner?"

"That is acceptable." Temple says writing down the terms.

So she steps out of the circle and asks Nick, "Where to?"

Nick flies out the front door and points her, and demonstrates a section of city-sinking, and comes back.

"Next one?"

While Nick was showing the dead city to the fairy, Temple retrieved a couple of large plates and filled them with water.

"Next."
