Ah, I understand what you mean, we call them Skill Trees, each skill resides on a different branch of magic. I operate within three branches: primal, spirit, and necromancy. For the record, we also have magical academies, we call them Circles. In the north they are places of learning...in the south, they are something else entirely.

And don't be sorry, it's important to be curious, I like a curious mind. As for how your magic affects the magic here well...it's a good question, isn't it? I've only noticed that the magic that I use is stronger than the blessings they give us here.
