You can really play as many characters as you like at this point, especially considering we're a relatively small group, and the fact that it's not up yet. ^^ Of course, you don't want to play too many characters.... I'll probably play a good amount of characters, but alot of them will be boring background types of little importance.
Magic, well, it'll use the same element system as the comic. It will be detailed in the info pages as soon as I get them up. My magic system is pretty different from the usual rpg system because your character can only use one branch, and their effectiveness as a wizard has to do with how closely related they are to a Ki-Leinahn (if they're human, that is. If they're Ki-Leinahn, they're always effective.) Either way, you only get one element to work with. You'll see, I'm working on it.
No rush really to have the characters finished. I've still got to get those pages up, then I'll ask everyone to write profiles.
