Nice to see some more people in here!

The only limitation on actual characters that I had in mind is their power. The Dungeon Keeper might empower them or give them armies and such later on, but at the beginning when we're raiding little hamlets it would be somewhat absurd to have a character that can destroy entire armies. If you make a sheet or even just share a concept, I will tell you if it's too OP. (The two characters that we have so far are fine.)

As in for participation, standard rules basically. If your character does quarrel with another and a fight breaks out, I'm mostly trusting the people involved to talk it out OOC or via PM to determine the outcome, or to just flow with it. Keep in mind that one character doesn't have to die; the fight could get broken up, one could flee, etc. If a character does die, I could just have the Dungeon Keeper resurrect them or something, or the person could make a new character. Hopefully we won't have a problem where one person seems to be metagaming or powerplaying, but if that happens I'll tell them to stop.

Did that answer you, or did you want to know something more specific?
