There's something very nostalgic about standing in front of a large audience and walking them through scrolls and then expounding on the principles of magic. She has more to say at this point, though, she's dissected more spells into their component pieces and Olórin's been around for a while now to help explore vast combinatorial explosion. The lecture takes a few hours even with most of the content offloaded into "look it up, it's in the files". And then there is food and mingling for anyone who doesn't have to race off immediately to do important multiverse things!
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."
"- they're not dead anymore unless something happened I didn't hear about?"
"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."
"They credit me with glass and the wheel. It's a bit much."
"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."
"Me either. Your Luster alt helped his Fëanáro invent it, presumably that's usually what happens."
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.
"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?"
"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."
"I think that's sort of what happened to Shadow? I'm not sure exactly how the cause and effect went."
