| Actium | Segmentum Pacificus; Macharia Sector | The Forge World of Actium is located on the far western fringe of the Galaxy, in Segmentum Pacificus, and a vital lynchpin in the Imperium's effort to bring order to the frontier. Actium was first brought into compliance during the Great Crusade, but was lost sometime after the War of the Beast to be rediscovered near the latter half of the Macharian Crusade. Actium's prominence in its home sector as well as to a limited degree the wider Segmentum is due to its ability to produce Battle Titans like the Reaver- and Warlord-Classes and the overall extremely high quality of its goods. | ||
| Aeris | Segmentum Ultima; Ougrean Rift |
Colonized during the waning days of the Great Crusade to insure that the forces of the Imperium would never lack resources, the Forge World of Aeris has been one of the main power in the Ougrean Rift, specializing in the study of the many natives primitive xenos forms and bacteria of its system and the others in this dangerous region of space. The ability of its techno-priests to turn even the most minute of their discovery into a formidable weapon has made them famous in the whole Ultima Segmentum and beyond. | ||
| Annihilation | Segmentum Solar | Annihilation is a vitally important forge world of the Adeptus Mechanicus, located in an unnamed sub-sector within the Armageddon Sector. This forge world was freed from the yoke of the Orks at the end of the 35th Millennium by the Ardent Shields Space Marine Chapter and a joint-Imperial Crusade and brought back into the Imperial fold. | ||

| Carthagus Minoris | Segmentum Pacificus; Uridian Isola, Orelian Sub-sector, Ostian System. |
Carthagus Minoris is a minor Imperial Forge World of the Adeptus Mechanicus located in the Uridian Isola, orbiting the Penal World of Carthag. Once acting as a stalwart stellar bastion for the garden world that was once Carthag, Carthagus Minoris has for the past six thousand years acted as the primary Adeptus Mechanicus enclave within the greater Orelian Salient, and a major hub of Imperial ship-breaking operations. | ||
| Chromica |   |
Segmentum Ultima | Chromica is an ancient Forge World, which was until recently only known for the impressive state of decay its Forges were in.

Now, with the ship finished, Chromica's finally begun to rebuild itself, reigniting its old and crumbling forges and rebuilding its orbital ring. |
D[]
| Damascus | Segmentum Ultima, Albion Sector | Damascus is a relatively minor Forge World located within the Albion Sector, on the border between Segmentum Ultima and Segmentum Obscuris. Though labeled a world for purposes of Imperial administration, it is not a planet. Instead, Damascus is a motly collection of servitors and ships carrying out asteroid mining; wheel and ball stations hosting research labs and living spaces; and a primary rod-shaped station known as The Great Forge of Damascus which hosts the majority of manufactoria. This menagerie is collectively designated an Artificial World. Given its population of barely two billion, however, it hardly deserves the designation, let alone inclusion in the Cartographica Imperialis. |

In the last few millennia, Ferrata's Mechanicus has endeavoured to increase their productivity and industrial output, and within a span of a few short centuries, hope to raise their production grade in the overall hierarchy of their fellow forge worlds. | ||
| Ferunus | Segmentum Pacificus; Azuran Sector |
The Forge World Ferunus is one of the most influential planets in the Azuran Sector of the Segmentum Pacificus, and the only Forge World of the sector. Settled less than two millennia ago by the remnants of a large Martian Explorator fleet seeking refuge after a devastating journey through the warp and harrowing encounters with daemons that shaped the founders of the world into a distinctly new culture, it has grown rapidly into a major regional industrial powerhouse in the Segmentum and is known for its aggressive exploration, examination, and destruction of xenos ruins across the galaxy as well as possessing several rare STCs. It is slightly larger than the size of Neptune in the Sol system, and covered primarily in a sparsely vegetated tundra with a breathable atmosphere. | ||

| Inferna | -Information pending- |   Symbol of Inferna |
Segmentum Obscuras; Border of Agripinaa & Cadia | Inferna is actually a collection of four different forge worlds in a single system with a distinct culture and belief system compared to other forge worlds. Their progenitor Zachariaz Pheist having a near godlike status in their legends.
The infernean forges were isolated for much longer than most other forge worlds due to a warp storm which only relented at the end of the horus heresy. Which the Infernean war host joined very soon after realizing it and attempted to hunt down the fleeing traitor legions as they entered the eye of terror. Inferna has an almost intact titan legion, on top of four forge worlds consisting of the Magma forge, the Flame forge, the Inferno forge and the Sol forge or plasma forge. Uniquely they employ cloning for most of their skitarii and several of their priesthoods. Due to having vast natural resources and four forge worlds, they produce vast amounts of equipment which they trade to the imperium at large. Due to problematic cultural beliefs and practices, they often come under inquisitorial scrutiny and are often forced to pay reparation tithes. |

| Ixchel | Segmentum Ultima; Heirant Vex | Forge World Ixchel exists as a relatively isolationist Forge, dedicated far more to its own expansion and success then to the needs of the greater Imperium. Residing in the largely unexplored and long-since-abandoned Vex Subsector of the Ultima Segmentum, It is this solitary nature that allows it to be such an autonomous power house. Yet, the primary point of interest on this Forge World is its special ancestry to Mars, lying in both its age and the relics that it possesses. As of the current era, the Forge World possesses one of, if not the best, medical capabilities to exist in the entire Imperium. Revered for their medical prowess, the Biologis sect of this Forge World is routinely seen traveling amongst the worst epidemics and warzones. |

Forge World of Khalvax is one of the several forges located in the Starvus Sector, being the most revered and ancient. The Forge World was formed after being discovered in M33 by Explorator fleet 492, also known as SilverEdge. The Forge World due to its harsh and freezing biomes took a heavy toll upon the speed in which was constructed, taking 2 millennia to finish construction and to begin the long process of creating gear and build a Skitarii Defense Force. The size of the planet is bigger than that of Terra by 8.22%, with gravity being 1% weaker. 80% of the planet is covered in a frozen ocean several kilometers deep. The other 20% exists in the form of 2 giant continents which act as the main area in which forging is performed. |

Ostrakan is a Forge/Fortress world, the only moon of the blue gas giant, a 6th planet in the Europas solar system, which is located at the edge of Garon Nebulae, Segmentum Tempestus. Ostrakan serves as a base for the local Adeptus Mechanicus forces and as an impregnable fortress world, the last bastion of resistance for the Federation, that will resist all but the Exterminatus-grade weaponry, as the surface is nothing but a frozen wasteland, and all life happens hundreds of meters under, in vast cavern systems. It was colonized under the initiative of the Europan Planetary Federation, after the secession from the Imperium of Man. |

| Pytervia | Segmentum Pacificus; Chiros Sector |
The Planet of Pytervia is a Forge World controlled by the Adeptus Mechanicus. It is unknown when the world was originally settled, as no records remain from that time. However, it is known that the World war rediscovered sometime during the Great Crusade, abandoned and empty, but fully functioning, albeit offline. An envoy was dispatched from Mars by the then Mechanicum, ever since; the world has stood strong and proud - A testament to the Machine God's will. The World's surface has mostly been covered in massive Manufactorums, what little of the Planet's original landscape are gigantic mountainous regions, overshadowing even the largest of the World's Manufactorums. As well as these mountainous regions, a single ocean remains; comprising over 7% of the World's surface. A large portion of the World's surface has been rendered inhospitable, due to a thick toxic smog covering these regions. |

| Tvastar |  |
Segmentum Ultima; Aeaean Cluster |
Tvastar is an ancient Forge World of the Adeptus Mechanicus, located within the Aeaean Cluster in Segmentum Ultima. They are known for their high-quality products and ‘collectionist’ approach to technological acquisition.

Tvastar had a troubled history before the Great Crusade and Horus Heresy with the Cluster it supplies, resulting in open conflict on two occasions. Despite this it has since forged a tightly bound relationship that rarely exists between Forge Worlds and the rest of the Imperium. |
