So I guess I'll be the first with Amon here, one of the Seven Deadly Sins (Wrath). I could not honestly find a whole lot of history regarding him, so I just ran through a series of historical events that seemed fitting for him to have an influence upon (bring Cain into a state of wrath against his brother Abel, for example). When roused he is pretty much a juggernaut of absolute destruction, though he has learned to temper his anger so he is not a raging Demon all of the time.
As I was not sure how everyone else would play their Seven Deadly Sins as it related to, well, ruling their respective continents I decided to have him pose as the human 'Victor Grigorievich', the voice of Amon. His logic is simply that his followers would be more like to perhaps listen to one of their own, though he may show his true colors as time goes on or if I just choose to have him expose himself.
Anyway, I am open to working out lines and plot for him as well as just figuring out the logistics of how this game will run. Hit me up.
