"About enough time for an Elf to start seriously thinking about starting a family, maybe, once they've done the other twelve multiyear projects on their list."

"I think we should take point on multiverse things lest they take several centuries to get around to them."

"Agreed."

So he heads in and asks Bright when he's planning to go visit the world with the temple-guilds. 

"Once I'm familiar with the cultural role of the temple-guild things, and have thought about magic interactions and so on, and have things prepared for a trade negotiation - I was going to go visit Kib, want to come along and I'll fill you in?"

"Sure!"

Upstairs they go.

Kib is there reading a book. "Hi."

"Hi! Bad time?"

"Pretty much equivalent to most times."

"Oh, good, I was going to talk to Timothy about my plans to make contact with the temple-guilds world - it needs a name -"

"Godspring?"

"There you go. So, first question, do we want to dunk any of our under-fives, I think solidly nope."

"I was discussing this with Cam. Goldmages would maybe be okay as Elves and whitemage daeva would actually be super convenient but you don't get to choose. Also unclear if the goldmage timetravel is wildly unethical -"

"Your world's got shoddy divination but something somewhere might have better, if we get that then -"

"...then maybe dunk Elf to-be-goldmages who we have alts of and know grow up into nice people?"

...Kib seems to be listening but doesn't comment.

"If Elf mages don't reembody as mages then we can always dunk them, kill them and reembody if we got a bad roll."

"Congratulations that was very Slytherin."

"Thank you. I've been working pretty hard on it. Anyway, if Elf mages do reembody as mages then that suggests Mandos could maybe just embody people as mages no dunking required and in that case we can get a couple hundred trustworthy goldmages -"

"Ooooh. If Mandos can embody people as mages then it might be worth having some bluemages parttime - revert the changes somehow - you can do that with chips, right?"

"Not quite, not yet, but Findekáno's working on it. Anyway, can't find out if mages daevafy until one of them dies and that requires getting lots of them to summon and if it turns out they do and there are problems -"

"There'll be problems, by the time they die they're mostly too disabled to look after themselves."

"Could have the Valar special-case them - they can't do it everywhere it takes too long but they could extend their lives indefinitely -"

"While they are too disabled to take care of themselves forever, yay. Also I think the whole economic structure is built around the assumption there're more working-age mages than retired ones to support, if you make it top-heavy it topples - or starts taking in way way more babies to compensate - or tries euthanasia -"
