Seth
From Lexicanum
Chapter Master Seth is the commander of the Flesh Tearers, presiding over the Chapter for over 100 years. In his time he has experienced many great victories, but has also seen too many of his battle brothers fall victim to the Black Rage. He has earned a great degree of enmity with most other Imperial armies he has fought alongside. Commanders of the Imperial Guard and of the Adepta Sororitas are often simply ignored, while other Marines grow frustrated with Seth's impetuous desire to instantly destroy all enemies.
In battle, Seth can always be found in the vanguard of his forces, leading his Marines through incredible acts of savagery and bloodshed. When the Flesh Tearers presence is not required on the battlefield, he becomes stern and dour, forever preoccupied with the doom he now believes is impossible for his Chapter to avoid.
