Blood Gorgons pg. 44

Barsabbas sighed wearily. First, he and Sargaulres wore their oaths of brotherhood. The Astartes implant known as the omophagea allowed for learning by eating. Through the implant they were able to ‘read’ or absorb genetic material that they consumed, the omophagea transmitting the gained information to the brain as a set of memories or experiences. The Blood Gorgons remembered a time when they had fought against one another. Although they had always been one Chapter, the Reforging was part of their Chapter history. The oaths reminded them of this, or so the veterans said. Barsabbas could not remember the Reforging. That was before his time and no more than a curious relic of history.
