Her search will be fruitless!

"I see no errors. Well done. My own efforts were sadly less successful. If there are differences in our histories, they are may be subtler than I can detect."

"Unfortunately I've never even heard a rumor to the effect that Shakespeare was a vampire or Da Vinci was a demon. I have heard that Bach was possessed?"

"I am only passingly familiar with his works, but it is worth exploring."

"I don't put a lot of stock in this because I think it's just someone who thinks it's insane that one dude could have had Bach's output, but yeah, could look into it."

"We may be out of luck finding something easily valuable, other than magic, which has its own hurdles. Fall back on the standard of long lists of obscure content producers."

"There are also books about magic, and local demons and stuff, which I imagine would not be duplicated. And the books about demons don't contain much practical information?"

"If they're amusing but useless, that should be safe. I am wary of spreading information about magic for approximately the same reasons you are about spreading summoning."

"Yeah. Although I suppose it's possible it won't work for daeva or something."

"Something else we should test."

"I can get you the book with the stuff I started trying first."

"That would work. We should clear off these circles first."

"You can probably do that more easily than I can."

"This is true."

Chalk dust: is swept into a neat little pile in the corner of the room.

"D'you have enough oomph to compress it back into usable chalk? How's this work?"

"I could." The pile rises into the area, then shrinks into a cylindrical shape, slightly smaller than the chalk was before it was drawn with. "I have to pack it more tightly to compensate for not having any water to mix in. But it should still be usable."

"Neat! Can you make stuff catch fire by friction without having to visibly move anything?"

"Hmm. That would not be impossible in principle, I suppose, but I have never tried."

"I assume the commonest uses where you're usually summoned to are generating electricity and moving cargo, maybe passengers too, around?"

"As broad categories, yes."

"Any cool niche applications it's taking me more than a few minutes to think of? Snowplow fairies? Clearing the Pacific garbage patch? Digging tunnels? How common is summoning, how frivolous do people get with it?"

"Moving snow and earth, yes. I have not personally been called to clear out any trash. Also lifting satellites or habitats into orbit or beyond. For fairies, the reasons for summoning can be very frivolous. We are easy to pay and the bindings are less complex than for an angel or demon. Whenever something needs to be moved somehow and it would be more convenient to draw a circle on the floor."

"It must lead to a really weird sort of employment market when you get a random person who was willing to spend a while investigating a random job, every time..."

"The sort of daeva who take summons tend to be the sort willing to perform arbitrary tasks."

"But it's probably hard to find specialists, to the extent specialization is a thing, and without a standard fungible currency you're gambling on what you get for it, too, and how long you'll be gone."
