Blood Angels, once the IX legion of the twenty original Space Marine legions. Their primarch, Sanguinius, was one of the noblest primarchs. Sanguinius sacrificed himself to save the Emperor's life, earning the respect and adulation of the subsequent Imperium. His legion, devastated by the psychic force of his death, developed a malady within their genetic augmentations known as the Black Rage. In addition, the Blood Angels are secretly afflicted with an urge called the Red Thirst since the days of the Great Crusade. These afflictions have led to the creation of a Death Company within the Blood Angels and their successor chapters. Composed of those who have fallen to one of the two flaws, each are watched constantly by Sanguinary Priests and reluctantly used as suicidal shock troops. Their chapter master is Dante.
