"Umkay...Sivath didn't mention any books, the unicorn didn't mention any books, you're from an Earth...d'you have mutants?"
"...We have people with various genetic abnormalities? You are saying it like that's not what you mean."
"My sister's a telepath and I control one of the four fundamental forces of the universe. This is because we are mutants, people with a specific gene that gives us nifty powers and/or physical anomalies. Some Earths have us, most don't, I was checking."
"Okay, let's go with A Study On Recent Human Genetics, by Professor Charles F. Xavier."
"Welp, you can make books from not your universe, it looks like. Probably from 'not this universe' too, considering that mutants seem to be a statistical rarity."
"I'd still rather know than not. Are your wings, circlet, and armor all from the same universe's system of magic?"
"Lessee...nothing from the one that wasn't a person...no..." she considers and rejects several objects before saying, "I have not really been paying huge amounts of attention to the names of individual magical objects, apparently!"
"Good! Randomly duplicating people without their consent would be massively unethical!"
"Yeah. I can't even do animals - I mean, I can make them, but they're dumber than they should be."
"Bugs and snails and stuff are about normal - you can notice differences if you give them elaborate tests, but they still basically function. If I make a cat, it'll have a hard time figuring out how to walk or meow."
"I don't think it's smart enough to contemplate the awkwardness of its situation. But I tend not to deal in cats etecetera."
"They can have normal kittens. There is now a decent population of all the more appealing animals, in Hell."
"Huh. That makes sense, I guess. How worried should I be about the fact that you are apparently a demon from a Hell? Not in terms of your personal evilness, but about the fact that your world has a hell that has demons."
