Wulongs have a higher ratio of witches to non-witches than most magical species do, because wulongs are an extremely convenient thing to be, so people opt into it a lot more often than they opt out of it; this correlation generalizes across pretty much all races except humans, for obvious reasons. Non-witch wulongs can't fly and none of them can go into art, but they all age slowly and stop at maturity, and they all can be resurrected in the same way. 

Well, that explains why they live in pocket dimensions instead of art. Does the Veil cover nonhuman nonwitches?

This book doesn't say anything about that, would she like to try another book or the Witch Internet?

She has that book about the Veil, right?

Yep!

Non-witch non-humans are covered by the Veil, but aside from the ones that would be easy to mistake for a human anyway if you didn't know what you were looking for, like Daeva and elves and some Empusas, they tend to prefer to live outside of human society anyway, because having everyone else see something different when they look at you than what you see in the mirror can be difficult actually. 

Reasonable! Where do they tend to live, more pocket dimensions? Alternate worlds like Alfheim? (Is there a technical distinction between those really?)

Most of them live in alternate dimensions like Alfheimr but there are substantial populations in pocket dimensions. 

This book doesn't have any commentary on the difference between alternate dimensions and pocket dimensions, but the metaphysics book she read earlier did; a fully-fledged dimension, like Earth or Alfheimr, can be described as a location within the hypersphere with a set of coordinates that vary depending on what system you're using, and spatially speaking, they go on pretty much indefinitely. A pocket dimension is a finite volume of space that has to be anchored to a regular dimension in order to exist. 

Wow, indefinite full-fledged dimensions. Intimidating and cool.

What's next?

She's a few pages into the book on Japanese witches when Edie knocks on her door. 

"Breakfast?"

"- yes, that's probably a good idea. Thank you for retrieving me out of my book hole."

"If I hadn't done it Emily would've. We've had loads of practice on each other."

May sets her book down and floats out of her room. "Do you guys all have to sleep?"

"I still do--for now--but Emily doesn't. I don't know about Ava actually."

"I shall ask her next time I see her then." To the cafeteria!

To the cafeteria!

Edie picks up a croissant and a handful of breakfast dishes she doesn't recognize and isn't sure how to pronounce. 

May grabs an omelette and a muffin and an OJ. "I think I'm hungrier than I used to be. Possibly staying up all night does it even though I'm also physically exerting myself less because I fly everywhere now."

"I'm okay with that! Magic just has so many ways to make food, I am so in favor."

"Yeah, I don't mind it particularly. My mom was jealous. Oh, by the way, there is a potion that makes stuff taste like meat but it has meat in it, no joy on kosher cheeseburgers."

"Oh well, I'll just have to make do with cheese on veggie burgers." 

"Sorry to disappoint." Om nom nomelette.

"Enh, probably other people who aren't me will be more disappointed. Also, people who aren't eating in this cafeteria, because damn, eating things with no meat in them here is no chore."

"It's remarkably good cafeteria food, I'm tempted to start doing the taking a picture of your plate thing."

"I don't feel especially tempted to do that but I have been writing down particularly excellent things to revisit later."

"There's an idea." Muffin becomes nuffin.

She munches her croissant. "It also lets me note the spelling so I can look up how to pronounce things later."
