Carnarvon
From Lexicanum
The High Chaplain of the Death Company, Carnarvon, bears a terrible responsibility as it falls to him to watch over all 400 remaining Space Marines of the Flesh Tearers Chapter for the onset of the Black Rage. This is a position he has occupied for nearly 250 years and it is whispered by many that the strain of watching so many of his friends and comrades descend into the Rage, becoming raving lunatics hungry only for blood, has started to take its toll on his sanity. At this time, he has the final word as to who must be inducted into the Death Company and which of those Marines must be permanently incarcerated in the Tower of the Lost when they fall so far into madness that even he cannot control them. When not in combat, Carnarvon spends most of his time within the Lost Tower, watching over his charges ostensibly to find a path that will allow them to rejoin the Chapter. However his constant secrecy has a great many of the Flesh Tearers questioning his motives.
