Oh, I like this! Count me in, one hundred percent. Most of my preliminary questions seem to have been answered already, but I have a couple:
1. So, I get that we're students in this academy and all, but I'm guessing there's going to be some kind of conflict that comes up at the beginning? In my experience, academy-style RPs die faster than mayflies without a story that draws the characters together... Not necessarily having something for them to fight, just something for them to do other than go to class and have schoolyard drama. I'm just saying, if it's only supposed to be about personal discovery and enlightenment through magic... It might not work out.
2. Most the magical disciplines are straightforward enough, but does Ouramancy include, say, speaking to the dead ("human spirits")? Maybe just restless spirits trapped on the physical plane? And, which of the energies would be expended by speaking to a Divine Spirit or a Devil? Sakra?
