The Mechanicus Priesthood of Ferraeus

You can find many common notes about the Machine Cult on the Adeptus Mechanicus page.

The Arch-Magos of Ferraeus is often a regular visitor at the Sector Senatorum, and considered to be a strong ally of the Sector Governor.

The Adeptus Mechanicus has a long and storied history, both as a part of the Prosperitas Crusade and in the wider Prosperitas Sector. The three major domains of the Mechanicus are their smog-shrouded Forge Worlds, Ferraeus, Castellum and Naximus Prime, where forge-fires are ever-hot and the entire planetary population is committed to ceaseless production lines, feeding the Prosperitas Crusade and the Sector as a whole. Outside these there are many ‘lesser’ domains, such as the manufactorums on Korimesta ruled by their Tech-Priest Overseers, and colonies tithed to the Mechanicus such as Olethros Secunda; and Tech-Adepts are found scattered across the Sector’s worlds, attending to various ancient machines.

However, one of the biggest draws of the Adeptus Mechanicus to the Sector, aside from its abundant resources, is an abundance of Archaeotech and ancient ruins. Vast fleets of Explorator Ships compete with rakish Rogue Traders as they blaze passages into the Untamed Worlds on the Rimward edge of the Sector, eager to find treasures of the Golden Age on human colonies untouched by the Imperium in thousands of years.

The three Forge Worlds of the Sector are all varied and unique in their nature, each one possessing its own complex political relationship with the Imperium. Because of the complex issues regarding the independent nature of these worlds from Imperial governance, one of these Forge Worlds predates M.41, having remained largely independent from the Traitor Regent of the Prosperitas Sector during the ten thousand years the Sector was governed by the Regency Government.

Ferraeus was the first of the Forge Worlds to be brought into compliance by the Prosperitas Crusade, the second primary objective after the conquest of Duroverum. It was taken from its original rulers and granted to the Mechanicum allies of Warmaster Durovera. Its rulers owe their domain to the Imperium, and they know this well; the Legio Ferraeus, the sole Titan Legion stationed in the Sector, has almost constantly been at war since its formation from Engines captured from the former rulers of Ferraeus. The Arch-Magos of Ferraeus is often a regular visitor at the Sector Senatorum, and considered to be a strong ally of the Sector Governor.
