"Yes, but perhaps not in my house. In case of fire."

"We can go outside and I can be a fire suppressant. By rolling around on the grass."

"How much fire is involved, it'd be very awkward if I lost a form..."

"If you what? Not that much, anyway, I screwed up plenty when I was learning and the worst I got was 'badly scorched'."

"Oh yes, awkward. Perhaps wizard based fire suppression."

"I am super confused right now," says Anlei.

"He's got a thing and if he exploded it'd be contagious. Not to you, to me."

"Oh."

"I can go light myself on fire at my newspaper-burning spot on the bottom of the world," he says. "Just in case."

"...the... bottom... of the world?"

"We're on the top at the moment. Nobody lives on the bottom."

"...what, um, shape. Is the world."

"Square."

...she seems to be having difficulty articulating her confusion.

"What shape were you expecting?"

"Sphere!"

"That sounds sort of awkward."

"Funny, I'd say the same thing about a square!"

"What's wrong with a square?"

"How does... down... work?"

...he points, slowly, at the floor.

"That much I can figure out without asking!"

"There's down magic. It makes things fall down. It points towards - I think it's 'sufficiently large flat surfaces', but I don't remember for sure, and I forget the exact numbers on size of surface and range of effect - the world has a flat top and flat sides and a flat bottom, so all of those surfaces have down. But only the top of the world also has nice things like plants and weather."

"...I've never actually checked, but I at least heard that my world is just a really really big ball, so big that if you stand on it you can't tell it's not flat, and down just goes toward the middle."

"I suppose there's'n elegance to that," says Aurin dubiously.
