[@Kimiyosis] I believe multiple familiars are allowed, but I'm sure that many of them don't want to share. (I'm sure for instance that a golem wouldn't mind, but Iravis would never be willing to share a mage)

I advise you don't walk in with a group together, but rather create 2 different characters that have little to no relation. Cmon, it's more fun to form the relationships anyways ;D

EDIT: Again for characters with teachers, write up a classroom post so that we can keep things moving quickly, thanks!
