Nod.

"Good night."

"Good night," sighs Kib, "I love you," and off he goes.

And one day a silvery light appears on the horizon and rises into the sky. The Elves crowd outside to get a good look at it. It's the color of Telperion.

"That looks like a moon," says Kib.

"Do moons just. Show up."

"Not as far as I know, but it was weird that you had shiny trees handling your lighting situation in the first place."

"The sample size is only two worlds."

The Moon improves morale. It's so pretty. Everyone weeps when it sinks away on the other side of the world.

"If it's a moon and not just a moonlike thing it'll be back."

"That'd be lovely. How does that work, exactly?"

"Goes around and comes up again on the other side."

The Moon, indeed, does this. The Noldor hold a council and invent a word for it. They scout enthusiastically with the extraordinary advantage of light. Some nice things are even mustered to say about the Valar.

The Valar: eventually copied the moon idea from another world after years of dark! Congratulations, The Valar.

Twelve moonrises after the moon shows up, Arda acquires a sun.

Kib adjusts his sleep cycle accordingly. Makes brighter shines with the new light source.

Sits up and watches the sunset.

The Noldor have far too many people to accommodate at the lake, and they prevail upon Ulmo to help them build a secret city in the mountains for civilians and spread out otherwise into fortresses ringing Angband and settlements behind the fortresses on the land where now things are growing. They accumulate new citizens quite rapidly. The continent remains free of orcs. Orcs make a few forays at changing that and Findekáno leads the dinosaur cavalry out to stomp them all to pulp. He does not really seem to find it satisfying. Kib has passed on that Maitimo does not like his name and FIndekáno calls him 'your grace' or 'my liege' and sometimes this wins the shadow of a smile. 

Feanáro figures out how to stop aging and hands Kib a necklace.

"Thank you." On it goes.

"I'm assuming we want to stop Lári and Aydanci at eighteen also? Giving it to them now will just stop them at their current state, I think."

"Anywhere between eighteen and twenty-five is reasonable. Differences in that range are mostly cosmetic."

"Then we'll have them ready by that time, and they can choose. How are you doing."

"Not making as much progress as I'd like on talking golems but I still expect to be able to manage them."

"I'm assuming weapons that can injure Thauron are the current best use of my time but I'm persuadable it's programming if there's important projects there."

"Nope, I'm gonna advise injuring Thauron."

"Five years," he says, "possibly six before I've got something nice and scalable."

"I should have a talking golem design by then at least, if that's a useful combination."
