Sounds really interesting and I wanna join, but a couple of questions.

Do the spirits have an identity, or are they just something thats there. What I mean is do we RP them, or are they just a part of us?

Also, if someone wants to RP a demon, wouldn't it be a tad boring having to just stay in the underground? or would they be able to roam living world if they took over a corpse, or am i just being stupid hehe?
