Still... political factions. I wonder if they'll be along species lines (humans/goblins/imps/undead/etc) or if some factions at least will consist of a loose coalition of various species (say, a group of environmentalists comprising of elves, humans and goblins).
Or perhaps it will be the Dragon Knights themselves forming coallitions based on some shared beliefs (say, one group consisting of Dragon Knights who believe the humans and goblins and whatnot exist solely to serve (and die) at their command and a number of Dragon Knights who think the lesser races should be allowed some rights and so on).
