Few forge worlds labour in so unforgiving a shadow as Agripinaa. Set within the Segmentum Obscurus and hard against the baleful light of the Eye of Terror, it is known across the sector as the Orb of a Million Scars, a name earned through age upon age of siege, bombardment and desperate defence. Where sacred worlds like Mars pursue the higher mysteries of the Quest, Agripinaa exists first to feed a war that never ends, and its priesthood measures worth in shells forged and guns shipped to the front.
The world's industry is bent almost wholly toward supplying the Cadian front and the fortress-worlds that guard against the horrors spilling from the Eye. Its manufactories disgorge munitions in staggering quantity, alongside its own jealously kept patterns of autogun and battle tank, and Agripinaan war-engines are prized for the reliability and punishing accuracy of their guns. Little of the ethereal reverence of other forges survives here; the creed of Agripinaa is grim, practical and forged in the certainty that the enemy is always at the gate.
That certainty has been proven in fire more than once. When Abaddon the Despoiler hurled his Black Crusades against the Cadian Gate, Agripinaa stood in the path of the storm and did not escape unscathed, great swathes of its industrial heartland laid to ruin as its cohorts were spent to hold the line. Yet the forge fires were rekindled amid the wreckage, as they always are, for the Imperium cannot spare a single world that arms the defenders of its most imperilled frontier.
Adeptus Mechanicus
Order of battle
The Forge World Agripinaa field the units of the Adeptus Mechanicus — a detachment from the roster:
Kindred formations
Other Adeptus Mechanicus formations
Forge World GraiaGraia is a forge world renowned for its unbreakable resilience and its fanatical devotion to the war effort of the Imperium. Its Tech-Priests are famed for their stubborn refusal to yield ground, augmenting their forces with redundant systems and unshakeable programming so that even grievous damage cannot halt their advance. Graia's legions fight on where others would break, their machine spirits and cyborg soldiers driven by an almost supernatural will to endure.
Forge World LuciusLucius, called the Hollow Forge, is among the strangest and most secretive of all forge worlds, a planet turned inside out around a captive star. Its Tech-Priests have achieved a command of teleportation matched nowhere else in the Machine Cult, translating warriors and even god-machines through the immaterium and onto the battlefield in the space of a heartbeat. From this cavernous world stride the Titans of the Legio Astorum, and its forge-guilds hoard techno-arcana the wider priesthood can scarcely comprehend.
Forge World MarsMars is the sacred heart of the entire Adeptus Mechanicus, the birthplace of the Cult Mechanicus and the seat of the Fabricator-General who rules over every forge world in the Imperium. Its rust-red surface has been consumed by ten thousand years of industry, buried beneath foundries, hive-manufactories, and the fume-choked spires of the Martian priesthood. From Mars flow the oldest doctrines, the most jealously guarded secrets, and the ultimate authority to which all other forge worlds must ultimately answer.
Forge World MetalicaMetalica is a forge world so utterly given over to industry that scarcely a scrap of natural land remains upon its surface. It is a planet of ceaseless machinery, its skies black with pollution and its ground a single unbroken sprawl of foundries and hab-stacks. The Tech-Priests of Metalica are famed for their vast, disciplined Skitarii legions and their belief in the supremacy of the machine over the frailty of flesh, marching to war in overwhelming, relentless numbers.
Forge World RyzaRyza is the great plasma-forge of the Adeptus Mechanicus, a world whose mastery of contained starfire is said to be rivalled only by Mars itself. Its priesthood venerates plasma as the very lifeblood of the Omnissiah, and from its armour-cradles come the finest energy weapons and reactor cores in the Imperium. Home to the Legio Crucius, the Warmongers, Ryza has endured heresy and endless greenskin invasion alike, its fires never once permitted to gutter and die.
Forge World Stygies VIIIStygies VIII is a forge world with a shadowed and controversial reputation, its Tech-Priests long suspected of dabbling in forbidden and xenos-derived technologies in their pursuit of knowledge. Masters of stealth and misdirection, the magi of Stygies favour cloaking systems, ambush tactics, and the study of alien war machines. Whether radical heretics or merely bold researchers pushing the boundaries of orthodoxy, the priesthood of Stygies walks a razor's edge between innovation and damnation.
