Watch Fortress Erioch rises from the void as a grim monument to endless vigilance, its ancient halls lined with the trophies of centuries of alien war. Positioned to overlook a region long troubled by tyranid activity and the raids of lesser xenos, the fortress has never known true peace. Its Watch Captains keep meticulous archives of every threat encountered, and these records make Erioch a place of dark learning as much as a garrison.
The warriors stationed here are drawn from across the Adeptus Astartes, and Erioch has forged a particular reputation for hunting the vanguard organisms that precede a hive fleet's arrival. Kill teams from the fortress specialise in tracking and destroying these advance creatures before they can guide the greater swarm to a fresh feeding ground. Erioch's brothers understand that a single scouting beast, left alive, can doom a hundred worlds. So they hunt without rest, striking in the dark and returning with knowledge that keeps the black shield sharp.
Deathwatch
Order of battle
The Watch Fortress Erioch field the units of the Deathwatch — a detachment from the roster:
Kindred formations
Other Deathwatch formations
Fort PykmanAn isolated Deathwatch watch fortress in the Ghoul Stars, holding the line against emergent Barghesi and waking Necron dynasties in the Imperium Nihilus.
Tyrannic War SpecialistsA doctrine as much as a formation, the Tyrannic War Specialists are Deathwatch warriors who have dedicated their Long Watch to the destruction of the tyranids. Steeped in the anatomy and instinct of the Great Devourer, they field munitions and tactics honed across countless battles against the endless swarm.
Watch Fortress NostradaWatch Fortress Nostrada guards a haunted stretch of the galaxy where ancient tomb worlds lie buried and stirring. Its garrison specialises in the war against the necrons, maintaining eternal vigil over dynasties that could wake at any moment to reclaim a domain older than the Imperium itself.
Watch Fortress Talasa PrimeThe headquarters and foremost training world of the Deathwatch, a fortress-planet within Ultramar where kill-teams are forged against the xenos.
Xenos Inquisitorial CadresThe most secretive arm of the Deathwatch, the Xenos Inquisitorial Cadres serve directly at the side of the Ordo Xenos. These hand-picked kill teams undertake the Inquisition's most sensitive alien-hunting missions, operating far beyond the sight of the wider Imperium and answering to inquisitorial masters alone.
