I have this idea for AU where it is crossover of Witcher and Harry Potter. Kaer Morhen is like Hogwarts and also has four Houses, but these are Witcher Schools, and students are trained to be monster slayers, not wizards. So we have houses:

Wolf - Very professional in combat and very unprofessional on a daily basis. Walking disasters. Cat - A bunch of crazy motherfuckers, don't mess with them. You never know what their triggers are. Griffin - Good guys and badass nerds. Very conscientious and responsible. Viper - They are quiet, deadly and resistant to bullshit.

(There must be four houses, so Bear and Manticore didn’t count, but maybe I will come up with something)

I still have to think about the setting, but I have this scene in my head (incorrect quote):

Berengar: Don’t do anything I wouldn’t do.

Berengar: So, don’t eat pears and don’t interact with cat that lives downstairs. You can’t trust him.

Lambert: I mean I’ll try, but if he talks to me first I’m not gonna be rude.

Berengar: Lambert cats don't talk. And you are always rude.

Lambert: Oh, you mean the cat-cat. I thought you were talking about Cat Witchers.

Berengar: Lambert, they're crazy like hatters, EVERYONE knows talking to them is a bad idea.

Lambert: And how about fucking them?

Berengar: Even I, with my death wish, wouldn't ever try it.

Lambert: Watch me.

btw it's just an excuse to have Kaer Morhne Shenaningans in Hogwarts AU
