The adults aren't worried about seeing socially irresponsible content; they are in fact all Kinslayers, or did Cam miss that. Maybe after they've put the children to bed. 

...what a charming vocabulary word that is. Sure, after-hours screening of Atriama with a machine translation into Quenya for subtitles. His machine translation is pretty okay at this point.

They are happy to stop using it, that's definitely reasonable orders, but what's the issue?

Oh, no, they can say what they like, this doesn't come anywhere near a genuinely important reason to limit freedom of speech, it's just. Well, Cam happens to think killing people does not become specially problematic if they are your own species versus if they are not.

There are no people in the system who aren't their species. There might not be any in the galaxy, depending what Eru's put on Endore. Except Cam. Everyone agrees that killing Cam would be far eviller than killing people who are backed up. 

Well, Cam's indestructible. But he used to be a human. And he doesn't know what Eru may have put on Endorë either but if it's people they're probably, like... people.

Point taken. 

Oh good.

Eventually there is enough rock to put atmosphere on! And land! Next to some lovely sustainable lava flows that can keep it from being too miserably chilly sans sun if they want to go outdoors, he doesn't want them to have to spend 100% of their time in arcologies, but he's gonna start with an arcology because that's easy to climate control and if he puts decorative plants near a lava flow they may catch fire and anyway are the Elves okay with this plan?

They are. Is it going to be super pretty? That's an important priority. 

They can consult on the design if they like! Here is the Martian arcology he's basing it on but if they want it laid out differently or with a higher fountains-and-gardens-to-other-stuff ratio that can be arranged.

They are overflowing with suggestions. Mostly good suggestions; a lot of them have backgrounds in design or landscaping. More fountains and gardens would be great. 

Then when they have agreed on a layout: arcology! This one the Elves may feel free to name after a day and a half debating.

Cam stocks it up with plenty of everything. He leaves them the ship in case they want to bail if he doesn't come back in a timely manner. Anybody want anything before he goes to the Endorë rendezvous?

"...Silmaril?"

"Haven't tried making one of those yet. What for?"

"They're bright enough it'd be like having the Suns back, and beautiful, and the greatest work of the King - it'd be reassuring to have it watching over us - and they are said to have healing properties though that wasn't relevant in Valinor and they slow decay though that also wasn't relevant in Valinor. And they're so pretty."

"...it might be a bad idea to have something sun-bright around. The idea being that the place is hard to find."

"We could keep it inside. They don't have to be sun-bright."

"Yeah, all right. Are they all the same?"

They all look the same. If there are subtle differences between the three no one knows what they are. 

Okay. Silmaril! Silmaril?

And there's an extraordinarily pretty glowing gemstone in his hands. The Elves cheer. 

"Huh," someone says after a moment, "it's not responsive to attention and conversation the way a Silmaril is."

"They're normally responsive to attention and conversation? What do they do?"

"Just - change the mood of the lighting, or bring out someone's features specifically, or change the light they're giving off to fit the music that's playing...they're beautiful in isolation but in occupied places they respond to the places."

"...maybe Silmarils count as minds. Animals smarter than about snails do, it wouldn't have to be a fullfledged person to count."

"That would make a lot of sense, actually. Silmarils are definitely smarter than snails. Huh. Well, they'll love their pretty gemstone even if it's not an intelligent pretty gemstone, and the healing and everything else should come through fine - the indestructibility? Is it indestructible like a regular Silmaril?"
