i like the idea of the different factions being made up of different species/races. i do think that the two heads of each faction should be vampires just so that we can logically say it's been a few generations? that also opens up the door for other species to branch off or seek to have a higher position. or if not vampires, a species that lives for many generations. i think that new ruler should be settled in their rule though so that it's not a new rule being overthrown if that makes sense. thinking about it, i also think that the new ruler should have had something to do with the old one leaving so that it's not so random for the old one to come back wanting to rule again? maybe? i feel like i'm rambling. :/
