==Forge Worlds==
<!---move planets list on this page to Imperial Worlds?--->

See [[Forge World#Planet]] for a comprehensive list of all Forge Worlds.

Forge Worlds are all based on Mars. Literally so -- the AdMech so revere the nuke blasted hellscape of Mars that they intentionally terraform other planets into it. Filled with a combination of research labs, libraries, churches, forges, warehouses and factories, the Forge Worlds provide the Imperium with the vast majority of their equipment. However this didn't stop the Mechanicum from setting up shop anywhere they could during Old Night and the Great Crusade, including the volcanic Mezoa and frozen Altus Ferro.

Each Forge World has their own color scheme, themes, and specialties, similar to Space Marine chapters or Imperial Guard regiments.

===8th Edition's Forge Worlds of choice are:===
* '''Mars''': The original. Likely has a C'tan (The [[Void Dragon]]) buried inside it. Mars is a radioactive desert wasteland where factories and other forge world bits are built on top of kilometer deep ruins of previous bits, all infested with insane robots, sentient demonic warp viruses, and other things that go bump in the night that have been dicking around since the Horus Heresy. Immediately after the Dark Age of Technology they went full ''Kin-Dza-Dza'' and devolved into atmosphere-less techno-barbarianism until the Emperor showed up after he conquered Earth.
* '''Lucius''': Teleportation and Armor specialists, as well as known for a strange "solar blessed" metal called Luciun. Lucius is hollow, with an artificial star inside. Was attacked by Hive Fleet Leviathan, they survived by hiding inside their planet and sending out hordes of Servitors, letting them get eaten, then using Servo-skulls to pull the techy bits back underground and put them on new cloned bodies before the biomass could be absorbed, effectively starving the Leviathan forces to death. Had a civil war called the Inculcata Schism that almost caused the planet to ''implode'' (teleportation specialists is a nice way of saying "experiments with warp tech"), so they wear red as a way to kiss up to Mars. This is a common theme among forge worlds as Mars seems to be the only one with even a speck of sanity and at least performs it's dumbass experiments on other planets instead of their own home.
* '''Agripinaa''': Right outside of and now the front line to the Eye of Terror. After Cadia fell a good number of refugees fled to Stygies VIII and Agripinaa... who forcibly conscripted them into their Skitarii and Servitor forces. They effectively blackmailed millions of desperate refugees, trapped on their planet and in orbit, and turned them into various flavors of mindless or brainwashed combat cyborgs (well, maybe brainwashed, they might just be cyborg soldier badasses sworn to Agripinaa). Although, given Agripinaa became basically the replacement of Cadia in a way, their reaction is probably a justified act of desperation especially since they weren't know for doing that to refugees before. Also known for sending incursions around and occasionally ''into'' the Eye of Terror.
* '''Stygies VIII''': Had '''two''' Titan legions based on it during the Horus Heresy, '''both''' of which turned traitor. They were saved at the last minute by the [[Eldar]], leading to them having a soft spot for Xenos (mind, they still fully believe in human superiority and conquering/exterminating aliens..it's just that they will consider appreciating that Xenos aren't totally worthless all the time). Home to the Xenarite faction, a faction that believes in studying Xenos technology, officially to better understand why Humanity's technology is superior. Stygies is also home to the "Runic Priests," (No, [[Space Wolves|not those]]), a faction of AdMech specialized in intuition, speculation, and improvisation. Ultimately considered "too big to fail," the High Lords of Terra declared they were to be left alone, despite flirting with Xenos crap and Heretekal science (because the High Lords generally are extremely pragmatic and don't give a shit about almost anything non-Chaos). Eventually the Inquisition found out and decided to purge the planet anyway, in the '''Xenarite Schism'''. Stygies VIII responded by unleashing a computer virus that constantly purges the Administratum and the Ordo Xenos' computer systems of any evidence or discussion of how Stygies VIII is technically a Heretek world, while the Xenarites went mostly underground. [[Deathwatch]] Kill Teams still frequently attack them, alongside various Xenos forces who want their tech back. Stygians are stealth specialists, which they will deny whenever asked; they're also known for pretending to be from Mars when needed due to their color scheme. Currently invading the Eldar Webway in an attempt at raiding the [[Black Library]].
* '''Graia''': Even more aspie than normal AdMechs, Graia are nearly immune to psykers due to being too logical to manipulate. Notable for their space station that covers a huge portion of their planet, which is actually a space ''ship'' which Graia move around, and even take through the warp! Recently it returned to Graia and then again departed, this time bringing Graia with it (making us all wonder how big 40K ships really are even if this is a giant one). Both Chaos and the Necrons target them for it. The whole Forge World lives on this <s>yellow submarine</s> space thing due to opening some sort of portal to ''somewhere'' on the planet's surface long ago. Known for refusing to retreat even when losses are guaranteed because to do so would mean their logical predictions were wrong (or there is some human spirit remaining deep inside...nah it's totally sheer ego). Red on their uniform is ostensibly because they are loyal to Mars, but actually because [[Blood Angels|they like blood]] (because logic).
* '''Metalica''': Metalica is a completely sterile world, no atmosphere, no life, no anything but ''metal''. This may or may not be due to an [[retcon|ancient copyright scouring]] by a musical group bearing a similar name. Their Titan Legion was nearly destroyed during the Second War for Armageddon; their Princeps was ordered by Planetary Governor and notorious incompetent boob/traitor [[Herman von Strab]] to attack a horde of Gargants that outnumbered them three-to-one with no support like suicidal maniacs, and when that predictably failed the Legion then [[Death Korps of Krieg|''became'' suicidal maniacs]] by [[Astral Knights|self-destructing]] in the heart of the Ork forces because they weren't allowed to retreat. Totally ''not'' the noise AdMech -- their guns are intentionally loud to ''proclaim the glory of the Omnissiah.'' Metalica is also known for being the first Imperium force to go on a Tyranid safari. That's right, they're '''[[Awesome|actively hunting Hive Fleet Leviathan.]]''' They are, in fact, ''so metal.'' Currently being besieged by [[Typhus]], who wants to claim the entire sector for Nurgle, who views its sterility as an insult; although he wasn't able to outright conquer it, he was able to corrupt it with a techno-virus that continues to manifest and cripple the planet every seven cycles.
* '''Ryza''': Energy shield and plasma specialists, who have nothing to do with the [[Tau]] because they managed to remain relatively unmolested until the Mechanicus found them again during the Great Crusade. They have been invaded by [[Orks]] repeatedly, to the point that most of their Forge World's output goes directly to its own self defense. The more red on a Ryzan's robe, the more important they are. Led an aborted invasion of the Maelstrom in an attempt to go after the DarkMech world of Sarum. Ryza has a sect of Ruststalkers that have gone rogue, but still worship the Omnissiah so whatevs, it's all good. Known for being very ''enthusiastic'' towards melee combat, may or may not be due to Ork influence. In short, their shield good, plasma good, and rip and tear good. Fuck yeah!

===8th Edition was nice enough to flesh out several back-canon Forge Worlds as well:===
* '''Triplex Phall''': Isolated, on the far east side of the galaxy, Triplex Phall has recovered a ton of STC and Archeotech but refused to give it to Mars. Basically AdMech Protestants. Mars now has a Skitarii Legion following them around with express instructions to warn Mars if Triplex Phall forces find anymore secret tech. Invaded by Hive Fleet Kraken, attacked by Typhus, and invaded by Daemons. We can only imagine the only reason the rest of the Mechanicus hasn't crushed them and taken their stuff is either the STCs are that potent or that the Machine Cult would rather space Protestants have it than to risk the data being damaged or destroyed. Or their STC data is useless junk important solely for religious purposes but not worth bothering with in the practical. Or the AdMech already stole it as it is extremely doubtful that Triplex Phall has the data to avoid however Mars has learned to enforce its will over the last ten thousand years (and the Inquisition's help, probably). That, or the daemons corrupted everything or Mars fears they have.
* '''Deimos''': The moon of Mars, gifted to the [[Grey Knights]] of [[Titan]] at the end of the Horus Heresy. Originally responsible for building the favored patterns of [[Rhino]] and [[Predator]] during the Great Crusade, they now make Grey Knight wargear and use Servitors to transfer the material between the Grey Knights and Deimos, mindscrubbing them at each end, allowing both organizations to keep their secrets. Deimos has ''three'' different Knight houses, because apparently the Grey Knights aren't enough knights for Deimos. Considering Deimos is about 10 miles across they are probably miniature knights, Epic Scale if you will.
* '''Voss Prime''': The most Mars-fanboyish of the Mars Fanboys, has a focus on Legio Cybernetica robots. Closest Forge World to Armageddon. Voss has a huge asteroid field that repelled an Ork [[Waaagh]] merely on accident. Known for good tanks, but crappy plasma weapons. Not to be confused with Voss, which is another Forge World not too far away from Voss Prime. During the [[Great Crusade]] they made enough [[lasgun]]s to ''arm the entire [[Solar Auxilia]] with''. Builds weird ships the Imperial Navy didn't ask for, like slow light cruisers and frigates with torpedos. Also, either Voss or Voss Prime builds ships double the size they normally are. Which makes for utterly terrifying monsters of the stars. Imagine a Retribution or Apocalypse or Emperor=class that's ''double sized''.
* '''Gryphonne IV''': The lost Forge world. They are responsible for a lot of Imperial Guard support-tank patterns, thanks to the real-life [[Forge_World#Company|Forge World]]. The Tyranids ate their planet after they refused to listen to Inquisitor Kryptman, so they have become the first nomadic Forge "World": a space fleet actively seeking out a planet they can terraform into a new Mars. Whether or not Gryphonnians want to terraform said world into (degenerate-biome barren world) present-day Mars, or a (lush and properly-terraformed) Dark Age of Technology Mars is anyone's guess. Gryphonne IV is ''definitely not'' [[Craftworld|copying anything]]. Bet they won't hesitate to listen when Inquisition experts tell them shit's about to go down next time.

The "big" Forge World remains Mars, with [[Cawl]] being the only unique character in the AdMech force. (Hieronomus Tezla says hello.) Lucius and either Metalica or Ryza (depending on the edition) round out the "main three" Forge Worlds, fluff wise.

However, each world has their own rules and details in the fluff, although the new ones remain somewhat intentionally vague for [[your dudes]] purposes -- Triplex Phall lends itself to odd conversions because "It's Archeotech!"; Deimos lends itself to borrowing some Grey Knights aesthetic and allies; Gryphonne IV being nomadic lends itself to battle damage and the like. Even the "old" forge worlds get some additional flavor in the new fluff -- Stygies VIII lends itself well to sneaky types or Xenos conversions and allies; Agripinaa force-conscripting refugees encourages Servitors / Skitarii converted from Imperial Guard (or even Ecclesiarchy and Necromunda). Metalica going on a ''fucking safari'' for Hive Fleet Leviathan splinter fleets just screams "Nid Hunter" Skitarii.
