Codex: Chaos Space Marines (2017), p50 — Company of Misery

Engvarr, the Destroyer of Dreams, first blade of the Misericordians

Since the degradation of their gene-seed in M32, the Desolate Brotherhood found themselves assigned to impossibly dangerous duties. Each time they won a reprieve, they were sent on an even more hazardous mission, plunging them into a spiral of dissolution and despair. After a catastrophe in the acid swamps of the world Misery, the Chapter took a new name and left their duties behind, forever becoming sworn enemies of the Imperium and the illusion of hope.
