"You were born in the shadow of the Omnissiah and all your life you have been surrounded with the great wonders and dire terrors of the Machine God’s arts. Ever since you were born you have been weighed, measured, codified and tested so that your masters might find your place in the great pattern; an unforgiving process that has fitted you well for survival and supremacy."
—Explorator Archmagos Thule, address prior to the Helstrom Pursuit.
A Forge World is the Imperial term for the numerous planets that are directly controlled by the Adeptus Mechanicus. All have in common a complete dedication to the manufacture of the various machines and devices of the Imperium, the pursuit and preservation of (ancient) scientific and technical knowledge and the worship of the Machine God. Because of the Adeptus Mechanicus' monopoly on technical knowledge and expertise in Imperial culture, the Forge Worlds are the Imperium's primary source of all kinds of hardware: from farming equipment to war machines such as starships, tanks, aerospace fighters, or even Titans. Ancient pacts between the Adeptus Mechanicus and other worlds and institutions of the Imperium oblige the various Forge Worlds to supply other planets and the various military arms of the Imperium such as the Astra Militarum with the products of their manufactoria.
Much of a Forge World is like an immense factory, with industrial complexes soaring into the sky and mine workings burrowing deep into the planetary crust. Forge Worlds build great numbers of complex technologies, like tanks or spacecraft parts for the Imperial Guard and the Imperial Navy. They are ruled by the Adeptus Mechanicus, whose training and research facilities are located there, along with the grand cathedrals to their deity, the Omnissiah, in which the ruling Archmagi of the Tech-priests enact the grandest, most complex rituals to honor the Machine God. The Adeptus Mechanicus’ fleets, its armies of cybernetically-enhanced Tech-Guard warriors and, most formidably of all, the Titan Legions, are also all based on Forge Worlds. The Forge Worlds are largely autonomous from the rest of the Imperium, as allowed by the terms of the Treaty of Mars that founded the Imperium in the 30th Millennium, and the Adeptus Mechanicus is loath to allow anyone on their surface other than Tech-priests and the legions of menial, cybernetic Servitors who labour for them.
The surface of a Forge World is normally completely covered in massive factory complexes that stretch across the horizon. Its ecosystem has been completely destroyed. The air is saturated with toxic gases and rivers flow with toxic runoff from the multitude of manufactoria. In many cases, even seas and oceans have been purposefully evaporated to make room for more manufactoria. However, the sheer amount of industrial output greatly benefits the Imperium as a whole. All of the items produced by a Forge World are constructed according to a very specific design formula that varies from Forge World to Forge World, even for otherwise identical pieces of the same equipment and these variant designs are known as that Forge World's "pattern."
The Forge Worlds were settled by Cult Mechanicus colonists sent from Mars, the first of the Forge Worlds, during the Age of Strife. Despite the difficulties with Warp travel during that period as massive Warp Storms consumed the galaxy during the gestation of the Chaos GodSlaanesh in the Immaterium, several interstellar expeditions were able to make their way across the galaxy, either using the Warp during a period when there were few storms or travelling at sub-light speeds in realspace. Hundreds of Mechanicus colonies were settled across the galaxy spreading their faith into every corner of human-settled space. These planets were allowed to remain under the direct sovereignty of the Mechanicus under the terms of the Treaty of Mars that the Emperor of Mankind signed with the Mechanicus to unite Terra and Mars beneath the aegis of the Imperium of Man in the late 30th Millennium.
While there are hundreds of Forge Worlds in the Imperium, the most important is Mars, home of the Adeptus Mechanicus' political and spiritual head, the Fabricator-General of Mars; and the Imperium's first Forge World. Other Forge Worlds include Ryza, known for its advanced plasma technology; Gryphonne IV, home of the Titan Legio Gryphonnicus; Agripinaa, a primary supplier of military goods to the Fortress World of Cadia; Phaeton, manufacturer of the Leman Russ main battle tank; and Urdesh, the primary Forge World within the Sabbat WorldsSector. Of all the Forge Worlds, only Trebor catered exclusively to the industrial needs of lost Cadia. One of the most sought-after creations from Trebor is its version of the Vanquisher Cannon, which is the most powerful of all the Vanquisher Cannon variants. During the Dark Age of Technology, the twin empires of Terra and Mars co-existed, to the mutual benefit of both. Trebor was colonised by survivors of colony expeditions from both Terra and Mars after they were lost during a Warp Storm. This forced both colonies to combine their knowledge and build the most technologically-advanced of all the Forge Worlds. Trebor was only re-discovered by Commissar Yarrick during the Second War for Armageddon in the late 41st Millennium. As a result, Trebor has sworn its allegiance only to Yarrick and to Cadia. Its arms and technology made a major difference in the continued defence of the surviving Imperial worlds of the Cadian Gate following the triumph of Abaddon the Despoiler in the 13th Black Crusade.
Life on a Forge World is harsh even by Imperial standards. The Adeptus Mechanicus grade, quantify and measure every child born in their domain to best find their use and how they might serve within the Omnissiah’s great pattern. The most promising are inducted into the ministries of the Machine God, destined, in time, to find their place among the ranks of the priesthood. Of the rest, a percentage of the most physically able are subjected to the trials of the Skitarii and other more secretive castes. For the majority, however, there is a place, willing or not, within the Forge World’s vast webs of production. Such life-long service forms the mass of skilled workers that maintain the Forge World’s industries. These menials (or labour units as they are known) are free to make what lives they can for themselves in conditions largely no different from those found on most Hive Worlds, that is so long as work quotas are met, order maintained and their masters’ arcane pursuits are not disturbed. For those that fail in their service, fall badly injured or are proven guilty of some crime, punishment is harsh as new labour-helots and organic servitor components are always in demand.
The Forge World of Amethal, a planet that houses a relic from the Dark Age of Technology that keeps innumerable daemons caged beneath its crust, was assaulted by Khârn the Betrayer and his Khorne Berzerkers during the 13th Black Crusade. Once Abaddon's objective -- the cracking of the daemon cage -- is achieved, his forces withdraw. Shortly afterwards, Khârn and his Berzerkers disappear in a tempest of gore.
