The Censer Bearers chapter come from an unknown founding. Records have been lost, be it willfully or otherwise, but the chapter is nothing less than devoted to their Primarch, Sanguinius, and the Blood Angels. Like other Blood Angels successor chapters the Censer Bearers have a robust Librarium. They believe that their salvation from The Flaw lies in their psychic prowess. It is not uncommon for even Chaplains and Captains to openly exhibit some amount of psychic ability during battle, be it moving and acting with unerring precision or loosing bolts of crimson lightning upon those who would stand before them.
The chapter does have a Death Company, however they claim to possess the power to suppress the black rage and master it. Those who exhibit signs are brought before their brothers to take the Oath of Focused Rage. From this point on they understand they must fully give themselves to the Blood Wards, psyker-priests who accompany them at all times. The Blood Wards vigilantly ensure that their bothers maintain their sanity through both psychic incantations and prayers to Sanguinius.
In battle the Death Company is an immoveable bastion of faith. They march forward laying down a fusillade of fire from their boltguns. They are unflinching under even the heaviest of weapons fire, showing not only their resilience, but unmatched discipline in their firing lines. The Blood Wards fill the role of both Chaplain and Librarian on the battlefield. Armed with force weaponry and carrying a Censer Angelus, they must continuously chant the incantations required to keep their brethren focused. A stark contrast to the to the Death Company, who remain silent save for the rage of their boltguns.
None outside the chapter know that the unmatched control brought by these incantations have come with a terrible price. The Censer Bearers have succeeded in a measure of control over the physical bodies of those who take the Oath of Focused Rage but The Flaw continues to burn deep within their mind, searing their very being from the inside out. What is left would be unbridled psychic rage if not for the constant chorus of the Blood Ward. With his direction that rage imbues their boltguns and is made manifest with every shell fired.
When a member of the Death Company inevitably falls in battle it is not always because they have finally succumbed to wounds caused by enemy fire, for nothing short of complete obliteration can stop them. Indeed, the Death Company of the Censer Bearers often times see multiple fields of war, destroying the foes of the Imperium under a hail of their own psychic rage until they simply burn out. A battered suit of power armor, the smoldering dust of their former selves retrieved by the Blood Ward to be blessed and placed within his Censer Angelus, so they may continue knowing war.
So this is what I came up with today. Rubric Death Company firing bolts of focused rage.
