" - that's vague..."

"A bit, yes." Cam unsnuggles to head for the relevant room.

"Hello," says one of the older Fëanáros, distinguishable from the new one by the clothes and the confidence at the computer he's flicking through. "They think their world is flat."

"The world is flat," Fëanáro and Nerdanel say in unison.

...

Cam makes their planet.

"Their world is, uh, apparently, flat," he says, watching oceans slosh in the plate-sized thing in his hand.

"How is it lit -"

"The Trees!"

"Your world is lit by trees?"

"The Trees."

"Like - green, leafy, biological -"

"They're magic, Yavanna made them, there's Laurelin and Telperion -"

She helpfully sends a mental image!

Cam sets the planet down. "Not appearing in this model because they're magic, I guess. Laurelin and Telperion were the names of the stars in the binary system around which Definitely Not Flat Valinor orbited."

"It wouldn't even hold together that way," whimpers one of the Definitely Not Flat Valinor Fëanáros. "What reprehensibly nonsensical -"

"At this size it holds without magic but maybe full size it needs - help -"

"The Valar made it?"

"Yeah."

"Did they say why they made it flat?"

"No - we weren't aware that that's not typical -"

"Is Endorë also flat?"

Confused blinks. "Endorë's right there," Nerdanel says helpfully, pointing at a continent on Cam's plate.

"This here isn't Valinor, it's Valinor and then some?"

"It's the whole world. That's Valinor -" pointing, "that's the Helcaraxë, that's Endorë, there's Cuivienen..."

"...okay, found another difference between the worlds, I suppose. I can, uh, personally verify that in the other world with Elves planets are consistently spherical and Endorë is its own one."

"- weird."

"No," says one of the chip Elves, "yours is definitely the weird one."

"Oh, I believe that," he says. "But - why the difference, why would so much else be the same..."

"What's gravity like near the edges, what's gravity like in orbit - can you put things in orbit at all -"

"You're not allowed to go to the edges." She kisses her husband. "We did anyway, but it wasn't very exciting, just rock and eventually it's too hard to keep climbing."

"Do you have stars?"

They nod. "Varda made them. But you can't see them in Valinor, the Trees are too bright."

"Are the stars spherical, or don't you know -"

"Don't know - how would we check -"

"I thought maybe Varda would have mentioned or something, if she made them; if you can't see them it would certainly be hard to verify - the Trees are just sort of on all the time, no night?"

"They take turns." Mental impression of what this is like.

"Okay, so the stars are mysterious, they are possibly not spherical since if they are that would normally be for the same reason as planets are..."

"I could ask Varda - or Aulë'd be more convenient -"

"...could you maybe postpone that, Vala attention on Milliways seems potentially hard to steer."

"Yes."
