"Firebreathing," she says. Ialdae jumps into the container. "White-group magic." Ialdae takes that too. "Shapeshifting." More ialdae. "The kids thing." Ialdae. "Your name." Ialdae. "And language." Ialdae. There are now little bits of leftover dragon magic hanging around in between the dense blobs of ialdae, especially in parts of the filled form slots, but for the most part, the contents of his magic container have been completely replaced. "It's way easier to do it when there's already magic in there," she adds.
"Um... I think the tiny little leftover bits aren't doing anything, and the big leftover bits are in places that weren't even doing anything before. I guess you need more magic to pick a form than to keep one, and after you're done picking the form for that space it just kind of sits around?"
"I don't know how thudias and vampires work," says Matilda. "How do they work?"
"And that makes sense if it takes less magic to have a form than to pick one, right," says Matilda. "Okay then. Jensal, your turn." She names the parts of the magic as she replaces them. "Firebreathing, shapeshifting, kids, language, name. All done. You don't have separate colour-group magic doing a different thing like the white-groups do, your shapeshifting section is just bigger."
Matilda spends a few ticks peering at each of them, and then replaces their firebreathing and shapeshifting and colour-group magic and reproductive magic and language magic and name magic. Everything works just fine. Everyone's used form slots retain splashes of dragon magic.
It occurs to Matilda to ask Jensal, "Why did you need to make sure the people taking care of the babies were fixed first out of the grown-ups?"
"But why is it bad to have baby dragons looked after by shrens? Is this about Draconic's opinions again?"
"Draconic has one large and despicable blind spot," shrugs Jensal. "We can think around it if we really try. But the Dragon Council doesn't try, so the baby-minders were early in line for miracles, and shrens generally avoid having children because they'll just be whisked away and given to some dragon couple who's failed at producing surviving offspring."
"...Some dragon couple who's what? Is that a problem dragons have a lot?"
"Of course I am. Where should I look? Who should I talk to? Do you know?"
