The Howling
The Howling is a conflict of the forty-first millennium, placed in the Segmentum Solar and associated with the Black Templars Space Marine Chapter. On the Orrery timeline it carries two hooks, the Black Templars and Cacodominus, and its map anchor is the Segmentum Solar, the region that contains Terra and the Sol system. Its span is recorded as running from the forty-first millennium into the forty-second, and accounts differ on how precisely it can be dated. The Black Templars, a Chapter of the Adeptus Astartes descended from the Imperial Fists and organised around perpetual crusade, are the principal Imperial participant recorded. Cacodominus is the name set against them in the timeline. The available record does not establish what Cacodominus represents in this context, how the confrontation began, the order of its engagements, or which worlds within the segmentum were affected, and this entry does not supply those details. The outcome and aftermath are likewise not firmly recorded. The event is best read as a documented link between the Black Templars and the Segmentum Solar, placed alongside other Chapter campaigns of the forty-first and forty-second millennia, rather than as a fully chronicled war with settled casualties or consequences. Readers following the Black Templars through the map and timeline graph should treat The Howling as a fixed reference point whose particulars remain uncertain.
