Cool. Research time.

And then dimension-hopping and or larceny for fabulous knowledge time.

Grand theft omniscience!

They head in. It's so good to have you back.

You too.

He goes back to work.

It worked, in a manner of speaking. He still prefers not to be alive because then he'd not be wondering if he'd wake up to Angband, and because then nothing could ever hurt him again, but he does not moment-to-moment find existence intolerable and if it were in his power to be absolutely certain that this were it and this were real and he could end his existence at will and would always have that option, then he doesn't think he'd exercise it immediately. And if not for the war crimes he'd perhaps even find living nicer than not doing that.

It wears off while he's at work. He'd forgotten just how crushing it was; he pretends to have a headache, sobs against the inside of his skull - very containedly, not moving a muscle - for a few minutes...

...gets back to work. It doesn't matter, not really. He forgot to chart his productivity, see if he was better when under magical assistance.

Wizards work on wizard stuff.

Eventually they have an interdimensional earwire. Fëanáro should call his parents.

Hi! I'm safe. I went to rescue Bella and now we're in an alternate reality where we're safe but lots of horrible things happened - Mom died, and then the Valar paroled Melkor, and then he killed dad, and then he killed everyone, horribly, and we didn't get to come back until now.

And so on.

And in case they do not find this explanation satisfying Bella is also available to earwire them.

They would like to speak to Bella, please.

So she calls them. "Hi, it's me."

"Bella," says Miriel. "I'm glad you're all right, what's going on?"

"After a few years back in my world I found a sort of transit demiplane and met someone there who let me into the world we're in now. It's another Arda, except thirty thousand years in the future; it got humans visiting Valinor but later than me and from a different world. And then Fëanáro found me, and it's lucky that his spell found me and not where he expected me to be but he's fine. We got Rúmil, and found the version of Fëanáro from here and we're at his house."

"And everyone's safe? And okay? We'll petition the Valar to let you all come home..."

"We're all safe. Um, I would not feel safe in Valinor, anymore, and I don't think Fëanáro would either."

"So is he planning to never come home?"

"Long term plans are kind of up in the air but we're not sure that if he goes back to Valinor he'd be allowed to ever leave again. If the Valar are willing to let people come and go that's another matter..."

"We'll talk with them," Miriel says, sounding numb and distant.

"I'm sorry. We're planning to figure out how to summon people from other worlds, you could visit here..."

"When will that - be an option, if it is -"

"In a few months, or less, it shouldn't be that much different in concept from what Fëanáro used to come find me."

"And you're sure you're safe where you are?"

"This is an Arda, but the Valar don't seem to interact with this part of the world, at least not anymore, and it's a science world and doesn't have anything roaming around looking for people to eat or anything."

They make sounds that communicate less than total reassurance.

"And this world's Fëanáro has seven children and they're around and I think they'd have mentioned if there were anything else we needed to worry about even if it would have slipped their father's mind. - The one here translated his name at one point so he's Fëanor for lack of a better distinguishing nickname."
