So I've been trying to put this idea together that involves wanking Bogomilism as a religion.
My own rough idea is that Bogomilism becomes the state religion of the Bulgarians (or even the Rus') with hilarity ensuing. Could this dualistic faith become dominant (or at least well-represented) in Medieval Europe?
