The complex the Adeptus Mechanicus installed is a pre-fab base of a type dropped onto countless worlds across the sector. It covers nearly a square kilometre with all its various buildings and warehouses, and was set over the site of a large section of ruins that extend many dozens of kilometres underground. Conversations and other sounds echo throughout the caverns below, lending an unnatural and disturbing feel to the area that lead the Guardsmen assigned there to begin adopting its more common name. The Tech-Priests, adepts, and their numerous servitors are unfazed by this, and only the others stationed here are bothered by it.
The base comprises three primary areas: the research labs, the habitat section, and the equipment storage facilities. The labs are the largest of the three sections and are heavily guarded by sentry guns crewed with integrated combat servitors; the Tech-Priests are well aware of the spies in their midst, and go to great lengths to conceal what they have found until they can determine its value.
While most of the research areas consist of standard rote data collection stations, repair altars, and Omnissian shrines, there are several facilities devoted to esoteric branches of study. Here, Tech-Priests immerse themselves in specialised quests some would deem skirting the bounds of tech-heresy, or delve into areas forbidden on more established forges.
The final section is for equipment storage and consists of five warehouses. Large machines for excavation, ground scanning, and other processes are housed here in four of the sheds. The fifth (and largest) warehouse is off limits to all non-Machine Cult personnel and is heavily shielded with genetic-signature locks. What is inside is a mystery despite attempts at infiltration. Disquieting rumours, though, hint of a maniple of fearsome battle automata—worrisome if true, as none can imagine what the Adeptus Mechanicus has found here that would require such militant firepower.
