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!
"He was probably experimenting. He quite literally couldn't help himself. No one tried reconstructing what he was up to, for obvious reasons..."
Antir circles the crowd and lands on Ferardrin's shoulder and then makes a perplexed face at Mitros. "Not him," he says to her, and to Ferardrin, "you're the first Finankar alt to look exactly like him."
"Ah. These are the - spellbinder familiars? Arcane magic might be able to do something about that, if you were high enough level - if you can even get high-level outside Materia -"
"Do something about - letting them exist independently without them and their humans endangering each other? That would be spectacular -" Cricket butts his head against her leg and she scoops him up. "- high level here is distinct from greater versatility and mana? Boots has done virtually all her wizardry outside Materia..."
"I mean, it might be a problem you could just throw enough versatility and mana at but in Materia high-level means the universe lets you do things, all the legendary spells and so forth that I've heard of that seem like they might bear on instantiating Hex's familiars were achieved by legendary people."
"It'd be really nice to be able to separate the spirit animals from people who don't want them. I tell myself they're just sleeping - that's what they do, if they're left long enough, they sleep more and more - but it's not as comforting as it could be."
"Yeah. I can't promise our magic will get you there but that doesn't sound like the sort of thing that ought to be impossible in principle."
"Thank you! It is nice to meet you! And you," he says to Cricket. "Cam told me about you when he first arrived, he said if he had an alt in my world they'd be okay if they were just rescued to a nice science world and handed you and a physics textbook."
"So I have been told!" And he smiles at them again and slips away to go tell an Elf that they have prestidigitated their hair green and from what he knows of Elves were not doing that on purpose.
