"They in fact marry in the standard continuity, so Luster's and Millennia's are - I am assuming Shadow is out -"

"- hmmm?"

"Uh, there's an Arda where the Enemy was sort of subtler and most relevantly this means Rúmil came out extra fucked up, was not in a position to do good supplementary parenting to the Fëanor, this snowballed and all seven of his kids there were badly brought up? ...details unpleasant."

"Then I'll trust Swift. And I assume the blue aliens don't interbreed with humans -"

"Can, actually, in morph, but yes, I don't think that's a good match either. Leaves you Shine, Elentári, Hex, and Space, which has five -"

"Are the Space ones differentiated to speak of?"

"Little bit - Space music isn't magic and they were delighted to hear there's somewhere where it was, so a couple moved to Telperion and the other three to Shine to help with modernization projects."

"Picking one of those if they all have close forks sounds awkward, but maybe just to me?"

"Little bit, and they might prefer to marry someone who can fork in case they decide to do it again - it turns out that Noldor, put in that setting, take forking to heart as a very important part of their culture -"

"Makes sense, with so much to do -"

"Yeah. So you want to point your sister here or at Hex or Stork - does she want to have kids -"

"Oh, are genderswapped alts, like, genetically siblings -"

"We might want to check."

"Cam was going to, maybe he's had a minute since he said that -" Check. "Yeah they are."

"In that case maybe introduce her to Makariel -"

"Human ones do not match," agrees Sibyl.

"Well, then, there we are, the small choir that will doubtless ensue from this marriage will not have any inbreeding problems."

"But if they're half-Elves they might not emerge from the womb as perfect virtuosi without magical augmentation!"

"I was assuming even unaugmented Makarial can sing?"

"Yeah, just not Elfily."

"How do half-elf kids even work -"

"Mostly like humans - no oaths, age to maturity fast and to old age eventually - Lúthien asked the Valar for a special dispensation from Eru for her descendants, they get to pick, maybe now the Valar'll do that for more people -"

"Seems like an awkward kind of decision, as long as there's going to be half-Elves and reasonable Valar around why not try to blend all the convenient features or something sort of like Golden's vampire hybrids project?"

"With fate out of the way, what're the advantages of humans?"

"Not being crippled by the presence of ugly things, nor paced somewhere between 'reasonable' and 'Ent', nor prone to ridiculous melodrama? I enjoy these features and imagine some half-Elves might want to share them."
