The Black Market is an underground community living beneath the Holy Cathedral of Gordius. Instead of going through the Conversation, they gain physical perfection through drugs and medicine. They also have good relationship with the outsiders and other races and are ever ready to topple the Holy Cathedral. 

They function without hierarchy and share what they have with each other. Despite so, they have a military system, trained in a secret monastery called the Black Abbey.
