...This is not unreasonable but Bar can't actually confirm identicalness except by checking publications and writing was really recent in their world.

"Are there any repentant Melkors, in general?"

This one time there was!

"I know 'darn it' is the wrong reaction but -"

Mirelótë nods and solicits published works on the subject.

This Arda (a space Arda) received an accidental interdimensional visitor from a world with no magic and which to all appearances forcibly made magic things which entered its domain run on physics. Melkor, currently on parole, seized on this opportunity to open an enormous portal between the universes and de-magic his own. It took three hundred Years, it worked, it looks to have killed Eru, and when it was too late to stop him he warned everyone to take corporeal forms when it happened so they wouldn't be erased. The Valar are no longer gods and some of the Maiar got deleted entirely but Melkor is by all accounts now a model citizen, though sometimes he punches people in the face and giggles 'I can just do that!!! Fate doesn't exist!' Sauron and Thuringwethil have kids.

...well, it's a Space Arda, and not identical to Mingling's one.

Mingling's Valar are also not very convinced that counts as a redemption arc.

Punching people in the face isn't an atrocity, but yeah.

They could maybe help with holding Singularity's Melkor, who has definitely done execution-worthy stuff, still?

Can they get his various Maiar too, so they're not running around trying to get around their oath as fast as possible in a panic?

If they have a list.

They can check who took the oath, because Cam made sure it was conjuration-verified.

How many is it?

Thirty-one.

They'll need more sets of Valar, unless they're all conveniently in one place.

Seems unlikely, their movements weren't restricted per se.

Then it'll have to wait. Maybe they can onboard the Valar from one of the Ardas creeping towards the pardon of Melkor - there are Elves monitoring that, right -

There are. With Bar's help, they identified publications in several different flavors of Arda that would be published the Year before the pardon and mark the time to intervene; unique ones are being watched individually. There are a couple thousand people on it.

She doesn't usually offer a service of alerting people when specific things come out in specific worlds but she has been convinced that it is sort of like providing a magazine subscription. Once this understanding has been reached there is no trouble about there being a thousand of them.

They pick one. Identify someone who is very sure their alt would volunteer and whose alt is very definitely childless. 

Cam crosses his fingers when he does the fork anyway.

And gets an Elf who is confused, then highly entertained by the whole situation, and wants to know if she gets with this guy she's liked for forty Years, and then will happily let the Sanity Valar into her world.

Well, did she, inquiring minds want to know and they might do this a few million times.

"I couldn't tell her," says her alt, "I'm gay, but we looked it up and they're happily married before they both die violently at Alqualondë, standard timelines."
