There's not much racing off; three new worlds, one with useful transmissible magic and one as big as Edda, is an important multiverse thing in itself. Food! Mingling!

Space Rúmil finds Telperion's Rúmil and Boots and thinks flat Ardas are weirder and weirder the more you get to know about them - Trees, really? Trees. Okay. Trees. What were the Valar thinking. 

"Yeah, even Materia has a sun. I don't think it's a star, but it is a sun."

"Our Valar -" he waves a hand - "shouldn't speak ill of the dead, but at least they got the concept of stars and planets down in its entire."

"- they're not dead anymore unless something happened I didn't hear about?"

"No, they're back, but in the intervening years we - came to terms with what they had been, and hadn't been, and complaining about them is now less appealing."

"I see. Anyway, they managed well enough to give Space Arda a huge head start, if I'd landed there instead of in a Flat Arda I would've been even more overwhelmed."

"We'd have been glad to have you but it sounds like you landed in a good place to make a difference."

"They credit me with glass and the wheel. It's a bit much."

"1179, huh? We had glass and the wheel but didn't have the movable-type printing press, yet, let alone computers. You'd still have been coming from a world with fancier consumer products."

"It's true. Although it took me longer to reinvent the crystal ball than to say that I was pretty sure you got glass by melting sand."

He laughs. "I cannot imagine growing up before the invention of writing."

"Me either. Your Luster alt helped his Fëanáro invent it, presumably that's usually what happens."

"I'm not surprised in the slightest." And he is interested in the history of Warp and of Materia, before they joined the multiverse at large - how did the Federation come about, how about the Imperium, how about the gods...

Boots is happy to comment on Materia and the Imperium and gods; she calls T'Mir over to talk Warp.

Warp is a little hard to summarize what with being "crowded", but T'Mir will do her best and she knows her Federation history.

The Federation history fascinates him, particularly all the ways the early-space-Age wars scared them into banning whole categories of advances - 'like the Valar, though I suppose at least it wasn't divine decree -"

"Did the Valar ban genetic engineering in particular or other things?"

"No, they were fine with that - Valian ecology comes standard on flat Ardas but was designed by us, on the Space one - new species is a taboo because of what Melkor pulled with orcs but I expect some day we'll move past that - anyway, they banned a bunch of categories of blessing development as potentially disruptive and the study of cryptography as antisocial."

"Cryptography in full generality?"

"Yep. You could sneak a tiny bit in as theoretical mathematics but it was the stupidest of restrictions."

"I've been told that by default Elves are exquisitely docile people who might in fact have negligible rates of peering into things they were not invited to see, but the idea that having password protection on one's files is antisocial..."

"Yes, it was not disastrous in the way it would have been in a human civilization - we managed to continue having electronic commerce, despite the fact you could trivially steal peoples' money - but sometimes I almost wish we were less docile, would have forced the Valar to reevaluate that outlook -"

"Nnnnno that's worse."

"...what happened?"

"I think that's sort of what happened to Shadow? I'm not sure exactly how the cause and effect went."
