if this is english christianiy, why do they pray to bethlahem and jerewlasem in church?
I'm trying to figure out what on Earth you mean by this. Bethlehem and Jerusalem are places and nobody prays "to" them. Some may go on pilgramage to pray "at" them but this is far from being a requirement of the faith. It's not like Christianity has it's own version of the Hajj.
The myth of King Arthur (yes folks, it's not real) is about warring kingdoms during the Anglo-Saxon era of Great Britain. During this period there was a large divide religiously throughout Britain. The Romans had brought over Christianity previously but there were still a lot of Pagan practitioners. It was only until Æthelberht of Kent converted to Christianity that it really started to become popular. So throughout the game you'll be torn between choosing one or the other as it was a major political issue at the time.
The game isn't about Christianity nor Paganism, it just happens to be set within a tumultuous period of Britian in terms of religion, and practically everything else.
