Accatran Ultima Segmentum. A Forgeworld of medium importance, homeworld to the Legio Destructor Titan Legion (The Beasts of Steel). Located near the Ork Empire of Caradon
Adrantis Five: (Segmentum Pacificus) Hyper-technical human-populated planet that had been isolated from the Imperium for over five thousand years. They had "turned to the dark certainties of science, and created many new and wondrous machines." Adrantis Five held Macharius at bay for two years before it was eventually destroyed by a re-directed comet. "Of its secrets, nothing now remains."
Agripinaa Segmentum Obscuras. An extremely important forgeworld situated near the eye of terror. Its proximity to the fortress world of Cadia, means it is the principle supplier of arms to the forges of the Cadian Gate. Was attacked by the World Eaters during Abbadon’s 13th Black Crusade but was successfully defending by Imperial Forces, including the Blood Angels Space Marine Chapter.
Antioc Segmentum Obscuras. Used to be a Forgeworld of medium importance until it was attacked an overrun by the forces of Chaos.
Alesma VII: Alesma 8 (part of the Virgonian cluster of star-systems in the delta segmentum, and the only inhabitable planet in its system) is actually a large moon left in orbit after it's anchor-world was destroyed in M.32. It's surface is barren and void of ANY sign's of life (save the refuge and centuries old shrapnel of marine technology blasted to its powdery white surface aeons ago when its homeworld was fought for between marines), yet underneath its surface lies an advanced and heretical society that had long ago turned its back on the empire. After having been out of touch for almost a thousand years, thier people began to consider the empire a strange folk tale from the old people's generation. Having been left to thier own devices for 7000 years, they developed a wonderful and harmonious subteranean culture, growing more complacent and advanced in thier sciences, eventually reaching out for the nearby balls of uninhabitable rock and attempting terra-formation.
At this point, Imperial Psyker's began recieving a faint sound from thier part of the universe, alarming them and their superiors. Currently, the Inquisition has been informed, and has taken flight towards Alesma 8.
Alsanta: (Ultima Segmentum) Ork homeworld of the Warchief of Alsanta, whose Waaagh overran at least five Imperial worlds between 450-996.M41.
Armageddon: (Segmentum Solar) Imperial Hive world. Site of three major wars against the Imperium. In the First War for Armageddon, Chaos forces led by the Daemon Primarch Angron invaded Armageddon, but were eventually driven off by a combined Imperial force which included the Space Wolves and Grey Knights Space Marine chapters. The Second and Third Wars for Armageddon saw Ghazghkull Thraka and his Ork minions battling for control of the Hive world to no avail, although Imperial losses were tremendous. Both Angron and Ghazghkull have independently vowed to return to Armageddon to witness its destruction! Footnote: at least one presumed Necron pyramid has been found in Armageddon's equatorial jungles.
Arx: (Segmentum Obscurus) Imperial research outpost and monitoring station that monitors the Arx Gap, an alternate route out of the Eye of Terror that bypasses the Cadian Gate. Abaddon the Despoiler raided the station in 139.M41 which marked the beginning of the Gothic Wars.
Attila: (Ultima Segmentum) Imperial Feudal world. Homeworld of the Attilan Rough Riders. Attila is somewhat smaller than Earth and has a single continent that covers almost half its surface. The center of this massive land mass is prone to such extremes of temperature that it reamins uninhabited, a baking desert in the summer which becomes a subzero sea of sand and snow in the winter. The bulk of the population are nomads who subsist from their herds of ovigars, gigantic shaggy and savage animals native to Attila.
Avellorn: (Segmentum Solar) Imperial Hive world. Site of a battle between loyal Imperial forces and the Iron Warriors during the Horus Heresy.
Avignor: (Segmentum Obscurus) Diocese of Avignor, presided over by Cardinal Armandus Hellfire. Adeptus Ministorum relic, Scepter of Avignor, enshrined here.
Baal: (Ultima Segmentum) Desert Homeworld of the Blood Angels Space Marine chapter. Consists of Baal and its twin inhabited moons, Baal Prime and Baal Secundus. In ancient days, Baal and its moons had earth-like atmospheres. Baal itself was a world of red rust deserts but its moons were veritable human paradises. However at the end of the Dark Age of Technology, viral and nuclear weapons decimated Baal and its moons. The few survivors were often horribly mutated due to the radioactive and chemical toxins that polluted the worlds and the once prosperous civilization devolved into a collection of tribal bands, some even resorting to cannibalism. Sanguinius, Primarch of the Blood Angels, landed on Baal Secundus as an infant and rose to god-like preeminence among the people of Baal. Upon meeting the Emperor, who had travelled to Baal in a quest to find his lost children, Sanguinius immediately recognized his father and bowed his knee before the Lord of Mankind. The Emperor blessed Sanguinius and thus the Blood Angels were founded. To this day, the Blood Angels recruit from among the greatest tribes of Baal Secundus and Baal Prime in a ritual that transforms the mutated aspirants into restructured superhumans that reflect both the physical beauty and personality of their primarch, Sanguinius.
Badab: (Ultima Segmentum) Homeworld of the renegade Astral Claws Space Marines (cleansed). Huron Blackheart, Master of the Red Corsairs, AKA Lufgt Huron, Tyrant of Badab, Lord of the Maelstrom, was grievously wounded by a melta blast near the end of the siege of Badab by Imperial forces. He survived (now almost half of his body is fitted with bionics) and his renegade Space Marine followers escaped to the Maelstrom from whence he leads raids with growing frequency. More disturbing is the distinct possibility that loyal Space Marines that have disappeared are later found fighting in Huron Blackheart's armies!
Bakka: (Segmentum Tempestus) Imperial Segmentum Tempestus Naval Base. During the First Tyrannic War in 745.M41, a battlefleet was despatched from Bakka to aid in the battle for Macragge.

The location of a top-secret research facility conducting experiments upon captured members of the Tyranid race. Inquisitor Soloman Lok was sent to the planet in M.41, by Inquisitor-Lord Varius to investigate the facility.

Biegel-9 Segmentum Unknown. World upon which the radical inquisitor Ralei founded a Xenos zoo. Here he kept numerous xenos species which he one member of staff studied. The facility was discovered by other members of the inquisition upon Ralei’s death and was investigated by one Inquisitor Sasham. The facility was destroyed soon after. The details of this investigation can be found in the book “Xenology” from the Black Library.

Bray: (Segmentum Obscurus) Imperial outpost. Fabius Bile is known to have landed on Bray.
Cadia: (Segmentum Obscurus) Closest significant Imperial world to the Cadian Gate, homeworld to the Cadian Shocktroops. Cadia has become a staging point for Imperial forces protecting the Cadian Gate from Chaos incursions emanating from the Eye of Terror.
Cadian Gate: (Segmentum Obscurus) A narrow corridor of stable space on the galactic southeast edge of the Eye of Terror. The Cadian Gate is the only predictably stable passage out of the Eye of Terror, and is therefore the site of frequent raids by the forces of Chaos.
Caliban: (Segmentum Obscurus) Home planet of the Dark Angels Space Marines. Once a lush planet covered in forests, Caliban was destroyed after the defeat of Horus by a civil war between the loyal Primarch Lion El' Jonson and the traitor Luther. A remnant of the planet and the rebuilt fortress monastery was fitted with engines and travels throughout the galaxy as the Rock, recruiting Space Marine candidates from nearby worlds.
Calth: (Ultima Segmentum) One of the most productive planets of Ultramar, Calth is an airless world whose inhabitants live in underground cities. Calth is famous for its shipyards, which provide the craft used by the Ultramarines as well as civil and military craft for wider use throughout the Imperium.

Chiros: (Segmentum Pacificus) Lush homeworld of Confessor Dolan, known for its export of luxury goods such as exotic furs, elixers, and narcotics. Through the preaching of Confessor Dolan, Chiros was the first system to resist Cardinal Bucharis' control. Other systems stimulated by the Confessor's fiery sermons rebelled against Bucharis' cruel regime, which eventually led to the tyrant's ultimate demise.
Colcha: (Segmentum Pacificus) Agri-world which successfully rebelled against the Apostate Cardinal Bucharis' control. Enraged with "righteous ferver" instilled by Confessor Dolan, the entire population uprose against Bucharis' regime, driving his forces from the system.

Devlan: (Ultima Segmentum) Imperial Mining world consumed by Hive Fleet Kraken 997.M41. The extensive system of Sentinel space stations around Devlan delayed the hive fleet long enough for a fleet of giant freighters to escape into space. A company of the Lamenters Space Marines held off frenzied attacks by the Tyranids until the last ship was loaded. Left surrounded and cut off, the Lamenters commended their souls to the Emperor and took a heavy toll of the invaders before they were finally overrun.
Dimmamar: (Segmentum Obscurus) Confederation of Light founded on Dimmamar c.M33, which professed a penitent faith that believed the sacrifice of the Emperor should serve as an example to everyone. Their ideas of poverty and humble living directly contradicted the the teachings of the Ecclesiarchy and was declared a heretic assembly ans driven to virtual extinction. Dimmamar was also the birthplace of Sebastian Thor, 292nd Ecclesiarch. Thor was a revolutionary preacher during the Age of Apostasy who led a rebellion against the treacherous High Lord Vandire and eventually became the Ecclesiarch, Thor I. Thor initiated the reforms that would eventually lead to the Reformation of the Ecclesiarchy.
Dorn: (Segmentum Solar) Imperial outpost, possibly destroyed by invading Orks during the Ryza campaign.

Epsion Octarius: (Segmentum Tempestus) Ork homeworld of the Over Fiend of Octarius whose Waaagh overran at least five Imperial worlds between 450-996.M41. During the jungle wars on Epsion Octarius, a Catachan regiment survived for nearly forty days amidst Crotalid infested mangrove swamps before reaching the Ork Gargant construction site of Grubnak's Drops. The savagery of the Catachans so impressed the Ork Warlord that he ordered his Gargants to be painted in green jungle stripes with red bandanas, in imitation of the Jungle Fighter's uniforms. Tyranid Hive Fleet Leviathan centered its invasion in 997.M41 around Octarius Epsion.
Espandor: (Ultima Segmentum) Forest world of Ultramar consumed by Hive Fleet Kraken in the Second Tyrannic War 997.M41. Espandor was settled during the Age of Strife by traders blown off-course and subsequently stranded by warp storms. It was the least densely populated of all the worlds of Ultramar.
Eye of Terror: (Segmentum Obscurus) The largest Warp Space-Real Space interface in the galaxy, the Eye of Terror was created by the birth of the Chaos God, Slaanesh. The Eldar are said to be responsible for this catastrophe through their unparalleled psychic indulgences and suffered the loss of most of their civilization as a result of the destruction wrought by the creation of Slaanesh and the Eye of Terror. The remnants of the Traitor Legions fled to the Eye of Terror after the Horus Heresy.
Estaban 3 and 7
Ultima Segmentum. Located near to the Storm of the Emperor’s Wrath. Two Forgeworlds located in the Estaban system. They are both large and important forgeworlds and serve as a base to the Legio Tempestor and Legio Magna Titan Legions Respectively
Eustis Majoris Segmentum Obscuras. The current “capital” planet of the Helican Subsector.
Evoria (my own system) Segmentum Ultima. Situated on the eastern fringe of the galaxy. This system is believed by the Adeptus Mechanicus to have been artificially created in an age before humans existed. Discovered and claimed in the name of the Emperor during the Great Crusade. The system is unique in that it has ‘shell’ of asteroids that severely limit movement of vessels into and out of the system. This system has been attacked by large Chaos fleets on no less than four occasions, each of which were repelled thanks to the defensive properties of the asteroid shell. It has also come under attack by Tyranids, which were eventually driven off with the assistance of the Angels of Fury Space Marine Chapter. A mainly martial society, whose primary tithe to the Imperium is Imperial Guard regiments. Is home to a small order of the Sisters of Battle. The dominant predator on the planet is the “Serrator”; a large reptilian carnivore whose primary prey is the free-roaming Larnal. The planet’s Stormtrooper equivalent are named “Serrators” in honour of the lethality and ferocity of this animal.
Fenris: (Segmentum Obscurus) Homeworld of the Space Wolves Space Marine chapter. Planet of "Fire and Ice," the planet's vast ocean freezes over completely for half the year. The thaw occurs when the planet's pronounced eliptical orbit approaches its sun, when the planet's surface is subjected to searing heat, triggering vulcanic and tectonic activity due to the increased gravitational forces of the sun. The only stable land mass is the small continent, Asaheim, where the Space Wolves have built their fortress within the bowels of the highest peak, which they call "The Fang." During the "Plague of Disbelief," Fenris was beseiged by the Apostate Cardinal Bucharis, but a counter-attack by Kyrl Grimblood's Great Company successfully lifted the siege and Fenris was never taken. According to a theory by the respected Magos Biologis Anatole Leviticus, Fenris may have possibly been unsuccessfully invaded by Tyranids in the past, due to the presence of the "kraken" (terrifying tentacled leviathans) that haunt the seas of Fenris.
Formund: (Ultima Segmentum) Imperial Ogryn world. Homeworld of the Ogryn hero Nork Deddog, where he returned to live in retirement as chief of his people at the age of 110.
Gathalamor: (Segmentum Solar) Imperial world. Diocese of the Apostate Cardinal Bucharis, who, after enslaving the population of Gathalamor, led a reign of terror called the "Plague of Disbelief" which encompassed a great crescent of planet systems spreading from Gathalamor north and west up to and including the Imperial Navy base of Hydraphur, northeast to besiege Fenris, and south to the gates of the Imperial Navy base at Bakka. Two events were to prove disatrous to the Cardinal's aspirations to rule the Imperium: the unsuccessful siege of Fenris and the preachings of Confessor Dolan from Chiros, who instilled rebellion against the Cardinal's regime wherever he travelled. Upon the announcement of Confessor Dolan's death on Gathalmor (after a public trial which allowed Dolan to deliver a three day speech), Bucharis' palace was stormed by a popular uprising, and Bucharis was literally torn limb from limb by the angry mob as he attempted to escape the planet by space shuttle.
Gathrog: (Segmentum Obscurus) Ork homeworld of the Arch Dictator of Gathrog, whose Waaagh overran at least five Imperial worlds between 450-996.M41.
Gorkamorka (aka Angelis): (Ultima Segmentum) An isolated Ork World inhabited by rival mobs of Orks whose space hulk crash-landed on Angelis, a planet under Imperial exploration. The small human population was all but eliminated by the catastrophic crash of the space hulk. The surviving Orks, driven by instinct, began to build their "Gorkamorka" spaceship which they hoped would some day lead them back to the stars to conquer the galaxy in a great, final Waaagh. Unfortunately for the Orks, rivalries soon broke out which slowed the construction of the great Gorkamorka due to incessant battles for resources and supremacy. Other races thought to exist on Gorkamorka include mutated humans (Muties), tribal humans (Diggas), and presumed Necrontyr. Gorkamorka is the setting for the game by the same name.
Graia: (Ultima Segmentum) Imperial Factory world infested with Genestealers and subsequently attacked by Tyranids during the Second Tyrannic War 997.M41 (Hive Fleet Kraken), but was sucessfully defended and cleansed.

Hydraphur: (Segmentum Pacificus) Segmentum Pacificus Imperial Naval Base.
Iax: (Ultima Segmentum) Agri-world of Ultramar. Iax is sometimes called the Garden of Ultramar. Its climate and fertility have made it one of the most naturally productive worlds in the Imperium. There are no large cities on Iax. The oldest and most densely urbanized area on Iax is the ancient fortress city of First Landing, whose tall citadel has withstood the barrages of invaders over the centuries.
Ichar IV: (Ultima Segmentum) Imperial Hive world infested by Genestealers and invaded by Tyranids in the Second Tyrannic War (Hive Fleet Kraken). Ultramarines led by Marneus Calgar in cooperation with Imperial Guard forces and Iyanden Eldar defeat the Tyranids and cleanse the planet of Genestealers. Marneus Calgar was presumably killed in the action.
Iyanden: (Ultima Segmentum) Eldar Craftworld decimated by Tyranid attacks during the Second Tyrannic War 997.M41 (Hive Fleet Kraken). The Iyanden Ghost Warriors are so named due to the craftworld's reliance on "Wraith-guardians" to bolster their ranks in battle.

Loquit Segmentum Obscuras. Homeworld of the Q’orl; an insect like race with a small empire located relatively near to the Eye of Terror. The Q’orl have a caste-based society, reminiscent of a swarm of wasps, with a single queen at the head, tended to by a huge swarm of her offspring. They have been noted to have dealings with the Eldar in the past, but now consider them untrustworthy after the Eldar(possibly Dark Eldar) kidnapped one of the Q’orl hive queens.
Luther McIntyre IX: (Segmentum Tempestus) Desert World. Home to the Ambull, Crawler, Sunworm, Micah Dragon, and other foul creatures. At least one Imperial Guard regiment has been recruited from Luther McIntyre; Commissar Yarrick served with them during his career.

Mackan: (Segmentum Solar) Imperial world which was the scene of an epic battle between the Blood Angels and Khorne Berserkers led by Abaddon the Despoiler.
Macragge: (Ultima Segmentum) Homeworld of the Ultramarines Space Marine chapter. Macragge is a bleak and rocky planet, with over 75% of its land mass bleak mountainous upland which is almost entirely devoid of life. The people live in fortresses built and maintained by the Ultramarines. The Fortress of Hera holds the Shrine of the Primarch, where Roboutte Guilliman is entombed on a huge ornate marble throne protected by a stsis field which prevents the decay of his body. Macragge was invaded by Hive Fleet Behemoth in the First Tyrannic War in 745.M41, a combined force of Ultramarines, Ultramar Auxillaries, titans from the Legio Praetor, and a battlefleet from Bakka successfully defended and virtually destroyed the invading fleet. During the fighting, the Ultramarine elite 1st Company was completely anihilated.
Maelstrom: (Ultima Segmentum) A large Real Space-Warp Space interface near the Galactic Core. The warp storm is home to Chaos renegades that use the region as a staging area from whence they raid nearby systems. The most notorius of these raiders is the Tyrant of Badab, Huron Blackheart of the renegade Astral Claws Space Marines.
Masali: (Ultima Segmentum) Agri-world of Ultramar. The planet is actually an arid desert world, but the inhabitants have constructed gigantic domed horticultural cities that cover hundreds of square miles, capturing precious water in wind traps and storing it in massive underground tanks. Tarentus and Quintarn have used the same technique, and all three planets are collectively known as the "Three Planets." In 759.M41, Marneus Calgar led forces which drove out Ork scavengers who had captured the Three Planets in the aftermath of Hivefleet Behemoth.
Medrengard Segmentum Obscuras. A daemon world, located within the Eye of Terror, currently occupied by the dread legions of the Iron Warriors. Theorised to be the location of Purturabo, the primarch of the Iron Warriors. The surface of the planet is primarily made up of chipped rock and waste materials from the planet’s vast and numerous weapon factories. The sky of the world is a featureless white expanse with a single black sun. The world also has extensive prison facilities in which the Iron warriors keep the many captives they take whilst fighting.
Methalor: (Segmentum Solar) Hive world which successfully rebelled against the Apostate Cardinal Bucharis' control. Enraged by "righteous indignation" instilled by Confessor Dolan, the population of its principle hive self-immolated themselves in a raging inferno caused by overloading the hive's geo-thermal power grid.

After the fall of Vandire and the enactment of the Decree Passive, prohibiting the Ecclesiarchy from maintaining a force of "men under arms," Ecclesiarch Thor I (Sebastian Thor) adopts the Daughters of the Emperor as an elite militant Ecclesiarchy force, thus establishing the Orders Militant of the Adepta Sororitas (Sisters of Battle) and bypassing the prohibition of an Ecclesiarchal armed force.

Tanith Segmentum Pacificus. Homeworld of the Tanith First-and-Only IG Regiment. A largely temperate world with vast amounts of land covered by Nalwood forests. Nalwood trees were unique in that they are capable of movement, meaning the forests on Tanith never remain the same. This led to the populace developing an excellent sense of direction, as they could not rely on paths through the forests that disappeared as quickly as they were formed. The capital city of the planet was known as Tanith Magna and was governed by someone called the Elector. Tanith was split into several provinces, each containing a “bastion” city. Its inhabitants had a culture that is often likened to that of the Scottish highlanders, many sported blue tattoos. The woodsmen of Tanith were called the Nalsheen, and possessed a unique form of martial arts called cwlwhl. A common curse on the planet was the word “Feth”.
