Different factions having access to certain kinds of magic was an idea floated around early on, and I'm sad it wasn't implemented. People end up going to the Church hoping to learn comic and holy magic and they're really not capable of teaching it aside from helping with dev. Giving factions easier access to their thematic schools and just waiting a bit for more mentors to pop up seems like a better option than completely ditching the original idea with tomes. They do end up making even basic spell trees feel unique and more personal to the character, and opening it up like before will likely ruin that.
Actually, fuck it, I'm going to app for mentor right now.
