"...Quendi?" offers Bella helplessly.

They mostly work on it when the not-Quendi are sleeping.

Which the non-Quendi do on a regular basis. The day cycle of this moon is a little longer than Earth days, which seem to be similar to Materian days. But T'Mir can stay up longer than Bella can, a week if she really wants to.

Fëanáro is baffled that anyone who could only sleep once a week wouldn't do that.

"It's not very comfortable and I can do less and less complicated and interesting things the less recently I've slept," she explains. "Besides, now I have mana to worry about."

"Mana is pretty annoying to worry about," he agrees.

"I usually find that going two days without sleep is plenty if I want to do anything more complicated than read or listen to music, anyway, and learning and doing magic and studying law and diplomacy and such is definitely more complicated than that."

"I get more energized the more I work."

"That's very lucky for you, then."

"I do fall asleep eventually though. I'm going to find magic to fix that." He scowls.

"But then how will you get mana?"

For which they receive all appropriate compliments.

Bellas can stay too, if they'd like! All the glass is to Bella's credit anyway. And there is a lot of glass, stone thin enough to be translucent is a hard trick to pull off outside Valinor.

It's very nice, but T'Mir is fine in her ship. It's cozy and she's used to it and it has her ship computer in it.

Bella's all settled into her bungalow, too, but of course will visit.

And the capital city is built, and crops are planted, and crop songs are conveyed by earpiece from Valinor.

It takes a little finagling to get the computer to accept earpiece calls, and it's slightly awkward to call T'Mir's mom and explain what's going on and ask her to buy Federation-computer-compatible music players for someone to go pick up (Davlians are working on getting system compatibility between their computers and Federation standard, but it's complicated work), but presently they have a device singing in every field.

....can a method of importing precious and semiprecious stones from Valinor be arranged? They'd make the city prettier and it looks like it'll be hard to find them here.

...sure, summoning objects is not likely to be technically impossible. If this is a priority.

Well, they'll need it anyway to steal a library, won't they?

This is true.

Accepting gifts from Valinor will be a good use of the spell before they try using it for grand theft library.

Reasonable. Work begins on object-summoning. This will also be convenient for immigrants who want to bring their homes.

The city is laid out to permit people to arrive with homes or without them, and for people who prefer living in beautiful open-air stone buildings or in trees or in ordinary houses. Trees are being sung up to make the streets shady.
