Geography

Ark'alask-Septimus is the seventh and last of Ark'alask's major ellipsoidal moons, although the gas giant is known to have more than two hundred moonlets of various small sizes in its orbit. It is a barren, rocky planetoid, with a thin atmosphere generally toxic to unaugmented humans. It is the furthest major body from the system's core, which is why it was chosen as the site of a Crusade armoury facility - ships could quickly translate out of the Warp, take in supplies, and be on their way without having to needlessly congest the busy Harkarialis-Primaris naval yard further in-system.

The moons's surface is a jagged jigsaw of mountain ranges and deep canyons, a testament to a more tumultuous age when it's core still burned. Now it is a dead world, although the infernal magma storms from the gas giant below keeps Ark'alask-Septimus warm enough to sustain life. This forbidding landscape is dominated by the eleven kilometer high peak of Karadon Indomitus. It is under this colossal mountain that the Imperium built its armoury.

Great Crusade Era

When the Harkarialis System was declared compliant, the Excertus Imperialis decided that its central coreward position made it an ideal candidate for a Crusade muster site. The task of evaluating the system's potential was given to General Alesky Kovaliev of the famed Volgan Assault Engineers. His report, delivered to Sector Command at Betalis in 962M29, detailed how Harkarialis was to be transformed to serve the needs of the Great Crusade as it pushed further into the Eastern Fringe. The only inhabited world, Uzun'kar, was to shift its industrial output from a mixed economy to the exclusive production of munitions. Kaska'irillis, already a major naval base, was be significantly expanded to serve as the main Armada Imperialis staging yard in the area. Kovaliev decided that it would be unwise however to site the system's main armoury at either of these locations, preferring instead to build it on the seventh moon of the gas giant Ark'alask near the system's translation point. Once approved, the colossal engineering forces of the Great Crusade set upon bending the Harkarialis System to the nascent Imperium's will. Thanks to the aid of the Iron Warriors Legion, work was completed in record time.

Vast amounts of war matériel produced by the teeming hives of Betalis as well as the local world of Uzun'kar were stockpiled at the Ark'alask-Septimus Facility, and even though the Harkarialis System was generally considered a quiet area during the later Great Crusade period, significant fortifications were erected to defend the moon from predation. At the core of these defences was the Ferrumskrag, the Iron Keep, a redoubtable fortress built along the eastern face of the great peak of Karadon Indomitus. Protected by powerful void shields capable of deflecting any void bombardment and half-kilometre thick curtain walls, the Ferrumskrag was designed by the warrior-engineers of the IVth Legion to be an impregnable citadel securing a major link in the Great Crusade's logistical supply chain. Furthermore, a vast network of forts, redoubts, and trenches defended the approaches to the fortress along Karadon Plateau, all designed to make any attack as costly and futile to a potential enemy as possible.
