The Blood Gorgons are a Renegade Chapter of Chaos Space Marines that primarily raids the Bastion Sector of Imperial space. They are an unusual Chapter of Chaos Space Marines, as every Astartes is ritually bonded to another through the use of a Chaotic ritual. The Blood Gorgons, who value their freedom and independence above all else, refuse to swear allegiance to any patron Chaos God, preferring to serve Chaos in general in the form of Chaos Undivided.
