That’s the year we’re now on in the Muslim calendar. The Catholic Church, in this case based in Arabia, reigns Supreme against an Orthodox Church based in Iran.
To modern eyes it all looks barbaric, but it’s in line with Christianity’s own history. As Europe Christianized it also devolved. The Muslim World dominated “technology” and trade for the first 500 years after the prophet, and then entered a dark time of internecine warfare that has lasted from that time to this, with various forces seeking dominance based – at least in part – on how orthodox they could be, on how hard they could make it for “true believers” to consider themselves true.
