CPI has a north building where all of the hybrids live. You can only live here if youre a hybrid but a really bad one, like you're really heavy or you have no eyes and see like a bat. It has a lot of special stuff in it to help with this, like they don't use glass at all (you can't see through them if youre that kind of hybrid) and the floors are super strong and sturdy (hybrids are really heavy a lot of the time). The rooms are also way bigger and the hallways are too. It's always really hot inside because hybrids can't handle the cold very well.

Lots of normal people live in the building too. There's just not a lot of hybrids and the school can't have the whole building go empty just because of that. So, a lot of people can live in it.
