This formation is made up of at least three Chaos Sonic Dreadnoughts and can contain as many as nine. The Dreadnoughts are led into combat by a fallen Chaos Lord or Chaos Champion of Slaanesh who has been eternally enslaved within a Dreadnought frame and daemonically-possessed through the enactment of occult rituals. To be encased within a Chaos Dreadnought cybernetic sarcophagus is a curse of eternal damnation for a Chaos Space Marine, and doubly so for a worshiper of Slaanesh as it robs them of the pleasures of the flesh, driving them completely insane. This formation is known to have been used by the Exquisite Host Chaos Space Marine warband during the 13th Black Crusade of Abaddon the Despoiler in 999.M41.
