The Valar announce that they've done as much as they can in Singularity (they can't bring back peoples' babies in that critical period either, but they can get them earlier versions) and are setting up portals between there and Sanity as soon as they are confident they've cleaned up the plague. A bunch of Elf architects have this wild idea for a fivedimensional city where alternating intersections are interdimensional portals between various Valinors and they get eagerly to setting it up.
And if they interview all of the daeva and look at all of the rest of the cases -
Murders, most less defensible than Celendra's. Rapists. Property damage. A couple weird crimes like getting a dozen random people pregnant or attempting to overthrow the government of Switzerland or the furniture angel.
The Elf who was interviewing the guy who got a dozen random people pregnant vomits on the spot and has to leave. They tell the lawyers it's fine to just push for a change in procedures from here forward.
Elves are satisfied. They reach out to the GCP to reiterate that sending daeva back to their home realms under a humane binding is always an option.
Well, they didn't actually let the GCP see it done so they're still skeptical. Also they checked and the fairy and one demon they recommended to the Elves earlier are not even on summon right now, their circles are still live.
Yeah, they're on the magic-dampening planet Varda set up for them, do they want to send observers to take a look?
"They can't take summons from there, they're effectively neutralized, the only difference between that and sending them home is that they're not at home."
The Elves really need to get the hang of saying what they actually mean and not things that they think are similar.
"I hope it has been expressed at some point that Elves experience prison as torture. To us it looks like you are torturing everybody constantly. I get a lot of questions from home about how we can in good faith have any kind of diplomatic relationship with a society that has prisons, at all. We are very committed to overcoming this cultural barrier but I think it will take a great deal of work on both our parts."
The GCP is not generically unwilling to entertain alternatives but it is going to insist on knowing what they are and how they can confirm that, and vague descriptions later proven inaccurate are not helpful. They are not imprisoning daeva at the Elves, and daeva are not themselves Elves, so this seems like an Elf problem.
"Okay. What we are doing is removing daeva from their realms to a magically monitored planet on which their magic is suppressed. From there they can contact attorneys and ask questions; they can at any time decide to instead be returned to their native realms to take a prison summons, yours or ours. If they decline to do that, we conduct a trial, the results of which will probably be indefinite detention on a supervised magic planet from which they cannot be summoned. Most people so far have chosen to return to their native realms under a binding, but the actual guaranteed outcome is 'unable to accept summons or interact with your dimension again, unless they are acquitted or until they've served their time."
"How do you prevent them from taking random or nonprison summonses while allowing them to take prison summonses?"
"A Vala accompanies them back; if they try anything the Vala can intervene instantaneously."
"You've mentioned before that the Valar are not the law enforcement branch of your government," remarks the observer, "and that we shouldn't expect what you anticipate of their conduct - at least insofar as you tell us about it - to necessarily follow."
"If there is a problem like that in the next five centuries or so I agree that would be reason to conclude we are not positioned to manage dangerous daeva. I am optimistic that problems will arise infrequently enough that I can speak with assurance at least over such a short span of time."
"At the time they had not clarified their intent, and I can tell you my confidence in it once I know it but I cannot direct it."
"One made the trial conditional on access to a not-yet-released human book, the other is engaged in an act of protest by declining to participate in the legal system, or so he tells us. That's a constructive refusal of trial, so yes."
"We generally don't leave that up to the daeva. They can be tried without their cooperation if necessary."
"If you advise that we proceed with a trial without cooperation we certainly can. What advantages does that possess over letting them wait around until they decide to cooperate?"
"Clearer records, and in our case it means we can't be sued for denying them the right to a speedy trial, which when some judges are adjudicating it applies even if the defendant doesn't want it."
"Our law does not have that provision but the clarity in records and the closure for the victims might make it worth it. I will suggest to my superiors that they start those trials."
