A Fëanor emerges. "Hello!" he says to the demon. "Curufinwë Fëanáro, but I put it all in the published paper -"

"Yto. I can't read Quenya and I don't know if the translation is any good because it's brand new physics nobody else has established vocab for, come on."

"That's appalling," he says, "I'll have a good translation of everything published in a bunch of languages, I didn't realize - Minor -"

"I know everything spoken on Revelation and all but three of Godspring's but I haven't actually picked up anything native to Hell yet and totally do not know enough physics to translate a physics paper and I'm not even sure there's a meaningful sense in which you could write about lightleapers in Cefaxi, it'd all be loanwords."

"Yes so that's why you should be listening carefully," he says, and to the demon - "what's your physics background, where should I start -"

The demon converts things and describes his physics education.

And gets a very enthusiastic and comprehensible explanation of how you get from there to lightleapers.

He raises an eyebrow at Niari. "They'll be at that all day, want to see out back?"

"Sure."

Out back is mostly Elves, singing, and the dragon enclosure, fairy-managed. "We were hoping that an effect of making the multiverse more interesting would be that more demons would take summons, and you wouldn't get a pool consisting mainly of ones who wanted to have an opening for trouble. I'd be curious if the rate of incidents bears that out."

"We've been getting fewer reports but we think that might be because people decide to summon demons and then change their minds before they actually get one."

"Is there a way to track the number of summons?"

"Not easily. Conjuration for valid circles over time gets interrupted ones just as well as ones that get daeva."

"Well, I'm very glad that incidents are down regardless of the reason. We've had some but we don't have a good baseline to compare against."

"Oh? What's happened?"

"Angel tried to persuade someone to snap her binding by claiming bindings were, like, physically itchy - another person heard and intervened, we're holding the angel for questioning - three cases of people committing suicide rather than pay the daeva, generally after agreeing accidentally to a deal that wasn't what they intended because of inexperience, miscellaneous sexual harassment complaints, one demon asked to hold a baby and then dropped it five times, claiming it was slippery..."

"...why did the demon get the baby back after dropping it four times?"

"Good question!"

"Are people who can't commit suicide casually having trouble with agreeing to deals they didn't mean to?"

"That's just Dwarves - and Godspring humans but they're doing only supervised summoning, right now - and there haven't been incidents reported. Neither of them are as naive as Elves so I'd expect fewer problems in that class - we're now running public service announcements -"

"We chip in to those sometimes too, but usually they're under SSA branding."

Nod. "People who've seen the war do not need an explanation that bad things can happen but in some of the societies where it's been peacetime for nearly four thousand years...they're running public service announcements with content like 'the linguistics society has now invented a word for 'forcing people to have sex' -"

"...didn't even need a word for it?"

"We hadn't, no. The violent crime rate in Valinor was, uh, six."

"Ah."
