"Not going to," Cam says. "If I were going to try to work with something ultra-short along those lines I'd go with 'the self-seeing' or 'the self-knowing'. How'd you figure out that'd work for you?"
"Well, that could have been a disaster, lucky you," snorts Cam.
"Is there some useful intuition here I should be cultivating or is that also just you?"
"I meant about stuff feeling true," Cam says. "But not getting my hopes up about a name less than nine paragraphs long is also important. Does co-casting split the same effort evenly, or unevenly, or does it cost more overall but less for every individual person, or is it more efficient energywise but also more time-consuming, or what?"
"Depends on the spell," says Matilda. "My intuition based on experience is that the bigger the spell, the more you win on a co-cast, and on tiny spells you lose. But I wouldn't say that's accurate to every case. For this size spell, it should come out about even on efficiency and cost much less individually."
Followed, presumably, by group casting.
"Cool," breathes Cam, when this is all over and he's warded up. "Is it just me or was something, er, listening to us?"
"How many of those are there, anyway? What are their ostensible specialties besides Iggy's and the Whisperer's?"
"I did notice that. So they're all in very snug cahoots? Or they're worried someone will learn enough to name them and do stuff to them?"
Renée calls them to dinner.
Dinner is macaroni and cheese with spinach in it, and side salads, with the remaining cookies for dessert.
