I'm considering a dwarven veteran of the last war, but I have some questions. How powerful can physical warriors become in this setting? How powerful can mages be? You say demons and angels could be overpowered, but there are no guidelines anywhere as to how powerful you want characters to be. I'm thinking ghosts, elementals, homebrew races etc could easily become problematic as well - it's freeform, after all, so abusing your freedom is as easy as having a bit of imagination.
