His true name is….
The Society of Blood is much more benign than its name sounds. Initially created as an award of valor for common foot soldiers, membership. The SOBs decided to make themselves a benevolent, protective order for all veterans. They quickly united informally and, without any bloodshed or even any overt threats, restored order and fairness for veterans through all the lands.
The Mad Pope is a wandering mercenary. He is very well deranged as he considers himself to be the pontiff of the dominant faith. His robes are tattered, his mitre has seen better days and there are surely lice in his long ratty beard. What sets him apart from most addle-pated would be holy men is that he has armor under his robes and carries a large crossbow and several one-handed swords. While many would discout him as just another lunatic, for some reason, he inspires others around him and has demonstrated the ability to lay on hands and heal the wounded.
