Gabriel Seth commands the Flesh Tearers, a Blood Angels successor whose ferocity has always sat uneasily with its allies. He is a stern and brooding figure, forever burdened by the knowledge that his Chapter is slowly dying, its warriors falling to the Black Rage and to attrition faster than the harsh world of Cretacia can replace them. Where other masters might rage against such a fate, Seth broods upon it, searching for any means to stave off the extinction he has been told is all but inevitable.
When he rose to command in the closing centuries of the forty-first millennium, his Chapter's chief priest gave him a bleak prophecy, that the toll of the curse and the endless wars had at last outrun the Flesh Tearers' ability to endure. Rather than despair, Seth made a solemn vow, that if his brotherhood was doomed to fade from the galaxy, it would be remembered with honour rather than dread. To that end he flings the Flesh Tearers into the Imperium's defence, mounting aggressive patrols and answering distress calls that others ignore.
In battle Seth leads from the vanguard, the first to hit the enemy line and the last to leave it. He wields the Blood Reaver, a monstrous two-handed eviscerator nearly twice the size of an ordinary such weapon, its teeth forged from the chainfists of the Chapter's first master. In his grip it becomes both weapon and banner, its guttural roar a rallying cry as it carves through the foe in great arcs of crimson.
Slowly his strategy bears fruit. Worlds that once feared the coming of the Flesh Tearers have begun to speak their name in gratitude, though old suspicions die hard and many an Imperial commander still eyes Seth's warriors with wary distrust. Seth himself cares little for their approval, for his war is against time itself, a grim struggle to purchase for his dwindling Chapter a legacy worthy of the angel whose blood they carry.
