He intended to use the Hulk to reap a campaign of destruction, culminating at the Hive World of Kefa Primaris'.

m41, anchored to kefa-primaris only for space-wolves::blood-of-asaheim::2: Lexicanum says only that the hulk was 'heading towards' Kefa Primaris and was intercepted by the Wolves; where exactly is not stated. No permanent position inferred.
archetypemedium
A space hulk; 'rock' as for the dataset's other hulks (Sin of Damnation, Death of Integrity), a generic drifting-conglomerate schematic rather than its true shape.
gposlow
inferred: book-specific position anchored to kefa-primaris (itself a relational rim point beside ras-shakeh). Anchor marker and within-system hull offset are editorial, not physical coordinates or a permanent berth.
