"Was that the time you traded me three weeks of snack tokens for rubbing alcohol?"

"Yep."

"Am I going to be extra-sanitary when we take it down?"

"Probably, yeah!"

"Cool. Ooh, I bet this spell would be good for, like, sterilizing hospital rooms, or pest control--I'm sure the mana cost is too high for practical use. But I'm going to enjoy it while it's up." 

"I'm sure there are better spells when all you want is to kill some bacteria."

"Or cockroaches. --Man, I wonder if the Void would go even harder if you asked for spells to kill stuff. Probably best not to test it." 

"I have studiously avoided taking creative writing classes after my first attempt."

"Oh, no, what happened?"

"Supervolcano."

"--Wow. Setting off an existing one, or making one out of whole cloth?"

"Oh, I'm sure it would have served for either."

"Huh...could you prevent one from going off, if it were going to?"

"Maybe direct it, not stop it."

"Hm. Better than nothing, if it ever comes up. Which I'm sure it won't, not within our lifetimes, but...did you know that Yellowstone National Park is a supervolcano caldera?"

"Yeah. If I ever hear it's blowing up I will take one of the many passenger aircraft still offering service to Wyoming."

"It's not going to come up. I'm just being silly. I think it's easier to just say things, in the dark like this."

"A little-known side effect."

They get to El's room. The shroud is taken down. Lucia fills several crystals and pulls a cloth out of yet another of her many pockets to clean argonet off her sword with. 

Aadhya counts remaining unfilled crystals. "Beads. I'll get on that."

"It would be sort of funny in a sad way if you eventually did have to take your sharer back because New York provided such a valuable parasitism service."

"If it comes down to that, I will solicit sharers from several enclaves, so it at least gets spread around some. Plus it messes with the symbolism. Can't say a power-sharer means I'm part of a given enclave if I'm wearing ten!"

"Is the block thing easy to put on one?"

"...I don't actually know?"

"It sounds like it'd be - not trivial, at least? I'm sure you could get some enclave to try, I don't know about ten of them."
