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.
"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."
"Now that some measures have been taken to counteract the potential damage, I would be willing to discuss the secret information relevant to the Swan trial if you think that would be conducive to rebuilding trust and helping your government understand our urgency in handling that particular case."
He frowns at him assessingly. "If you can arrange a location where we can be certain there are no unchiplocked recording devices I would be delighted to discuss the matter further."
"We were about to go look in on your daeva planet, weren't we? Does that meet the requirements?"
"That will suffice, yes. There's a stable portal there to Tirion but I can arrange for a special one. Let me know when is convenient."
"I'll report in to HQ and then I have no other demands on my time for the next few hours."
The representative checks their (lack of) bindings. "I've never actually seen a daeva not on summon," he remarks. "I suppose that would be obvious."
"We haven't visited the daeva realms either. There were a few thrill-seekers who were tempted and promised they'd cover the resurrection, we said absolutely not."
"Daeva won't assume people they see in their home realms are fragile, they could easily kill someone by accident and would probably find that upsetting, there could be outcomes worse than death that we'd then have to divert resources to handling..."
"Hm. Is it safe to get closer to them? They're not bound, I don't know how to look for other restrictions on their behavior."
"Around here their magic doesn't work. There -" indicating the boundary - "is the deceleration zone for if a fairy decided to fling something at us from where magic does work."
