"They can."

"So maybe humans have souls, or have them in some worlds, maybe they appear at birth or before that or after that, we don't know, we can consult assorted deities."

"Sounds good. How much do humans need to know or how closely do they need to follow instructions in order to summon safely?"

"If you distribute premade circles, they just need to complete those, keep their mouths shut, and concentrate on dismissal for a minute and then poof they're summoners. The problem is if they alter the circles, have to make their own and make mistakes, talk to the daeva and wind up saying something that counts as agreeing to task and payment, or fail to dismiss the daeva and leave them trapped in their circle forever. Daeva are separately useful to employ but you can have specialists do that."

"Yes, I think I will. People won't experiment, they are used to the stakes being high."

"You can cut the risk further by having the circles summon specific vetted daeva but that'd slow things way down."

"What risks are we looking at?"

"Angels and demons in particular can incapacitate their summoners and then go wreak nearly arbitrary havoc, demons at larger scales. Fairies have a harder time preventing their dismissal but there's plenty of damage to be done in a minute."

"I'll make sure people are adequately warned and have better options than secretly attempting that."

"The rollout went okay in Revelation with a few hiccups more than outweighed by the end of material scarcity - we've been concerned about extending it to Hazel, the world with the wizards, because it's early enough there that most of its population is illiterate."

"Most of my humans can read but the ones who can't can still follow orders."

"You've got substantially more power than any human government. And it sounds like your people are less desperate."

Nod nod.

"Once the Enemy's dead we'd delightedly take immigrants, though I would worry about successful integration if there were going to be millions of them."

"That's sort of the problem, we might find loads of places to put immigrants but not enough to accommodate all the ludicrous number of worlds there are. Also your planet is flat, it might get crowded."

"Timothy, what are the barriers to doing this in Hazel directly -"

"Someone would kill me within a week but I guess we can specify I daevafy and get the wizardry working again? You seem to be pretty confident you'll get good outcomes from these military tribunals for everything, I don't have very many people I'd trust in that capacity and I'd need a million of them - I don't know how you have people reporting internally or how well it'd scale up for a population of a billion - people are loyal to their extant governments and religions and so on and it's currently popular to dispense with monarchs and I'd have insurgencies everywhere -"

"Humans on their own kind of have to self-organize in ways that are robust against or at least poison-pilled for hostile actors coming in and telling them to do different stuff."

"Ah. Ours were new and didn't have that yet. Which the Enemy had great fun with, of course - he found them first -"

"Singularity's landed next to orcs but the war didn't last all that long - what happened with yours -"

"Ah, Sauron showed up when they were only a couple weeks old, taught them to worship Melkor, taught them that the most devoted such worshippers wouldn't be murdered by demons, enforced that, orchestrated a few wars between the new humans and nearby tribes of Elves, helped the human victors of those wars keep Elf prisoners alive long enough to get an answer on how Elf/human hybrids turn out-"

"Delightful. I suppose this at least left them used to - top-down organization in a way that made them relatively easily transferred to new leadership -"

"Haven't had trouble integrating the tribes that escaped his attention either, but it didn't hurt. - hybrids work fine, don't have native osanwë or oaths, age to a human thirty-five or so and then stop..."

"You don't sound anywhere near appropriately horrified."
