Needless to say I glossed over a lot. Not everyone in Bulgaria was particularly keen on converting to Christianity, for example. Boris ended up executing a lot of people and having his own son blinded, but it worked, Bulgaria is Christian to this day. Furthermore, Boris is a saint. Considering the kind of things he did to people who disagreed with him, I would have canonized him too, just to keep from pissing him off.
That thing on my head in panel thirteen, incidentally, is not a fez but a traditional Bulgarian lambskin hat called a kalpak. Drawing myself in a kalpak was fun. I think it suits me, don't you?
