Well, this certainly looks like a K’tonian artifact but if you notice the grooves on the bottom, that means that this was actually made on a Jiyong potters wheel as an imitation of the K’tonian style of pottery. This is a replica, albeit a 700 year old, very good replica. I do happen to know a buyer who would be willing to pay you for it.
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.
