"Dwarf spells are like elf ones - friendlier if you're in the family or some sort of tempermentally inclined but theoretically usable for anyone," says Bella. "I go ahead and wrestle with a dwarf spell whenever I want to work on something metal, but it's not often - I substitute when I can."
"Well, now I know what kind of magic it is, I guess. I never really thought about it before."
"...You were doing magic without knowing what kind it was?"
"...Huh. Well, it looks dwarven to me, but I'm not enough of an expert on dwarf magic to say for sure that there's nothing else mixed in there."
"You should. I am a magician and we know these things," says Bella grandly.
"Just how fire-witchy are you two? My specs aren't that fine-grained. They just say 'not zero, not all the way', but if there's books on thinned-out fire-witch families I haven't got copies."
"I think maybe it was our... great-great grandma?" she hazards. "And it's been pretty strong in the family since then, we're the first generation with no red hair. But we still do the fire thing and the knowing stuff about stuff thing."
"And it's hard to tell about the rest, because the royal family of the Enchanted Forest also has a strong natural affinity for magic."
"The fire thing. There's parts to the fire thing - does your hair burn when you're mad? I saw you do an ignition -" She waves at Tony. "And the frost spell bothered you, although you were perfectly talkative and so on so I don't know how much -" She waves at Sherlock. "I'm not getting much of an impression of a temper off either of you - you were pretty calm about the wizard, sword or no sword - do you cry fire? Could you push magic into a wizard's staff and explode it? Thanks for not doing that if that's a thing you could've done," Bella adds, "I've never gotten hold of an intact recently-used staff whose owner wasn't liable to steal it back a few days later before."
"Yeah, Sherry can be a real firestorm if you piss her off bad enough, it just takes a lot to get her going these days," says Tony. "Which is a good thing, 'cause we live in a forest. I dunno about exploding wizard's staffs, I've never tried."
"If you're worried about burning down swaths of forest I could probably make you gear for that," says Bella. "Like my marble, only I think I'd make them out of something else if they were intended to contain fire-witch magic specifically."
"I have not set anything on fire that I did not fully intend to set on fire since I was nine," says Sherlock. "I believe I am all right on that front."
"Stores magic. It's like a wizard staff - some of the same basic principles on the storage end - it'll take all kinds, it could store fire-witch magic without exploding but it wouldn't like it - but it's not a thief. It takes runoff from my spells, anything I generate by accident, occasional donations. Then if I ever need a lot of power without a lot of time to prepare, it's there."
"I think so! I like glass in general, the specs and the marble are good examples of its uses," says Bella. "That and windows and kitchenware."
"The limeade pitcher, you saw. Mixing bowls and so on. I have as much as I can in glass and then it's easier to add it to the general spell I have over the kitchen that makes it so cooperative."
"If you want to park me in your kitchen for a day or two, I can do that," says Bella merrily. "The cooks aren't quick enough to suit you?"
