Terra, or, in the most ancient records, "Earth," is the Throneworld of the Imperium of Man and the original homeworld of Mankind and of the God-Emperor. It is the most sacred and revered place in all the million worlds that comprise the Imperium. Billions of human pilgrims from across the galaxy flock to Terra -- even the barren and contaminated soil that these pious folk now tread upon when they reach humanity's homeworld is considered sacred by the faithful of the Imperial Creed.


Before the Great Crusade, Terra was plagued by a long age of post-apocalyptic civil war and anarchy known as the Age of Strife, which only came to an end when the Emperor personally waged the Unification Wars to reunite all the Terran factions under His own enlightened leadership.

Today Terra is the slow-beating heart of the Imperium, a sacred world of power and majesty that has become legend for most of the people of the galaxy. It is the site of the Golden Throne; the demesne of the divine Emperor of Mankind. The breathtaking architecture of its soaring buildings strike awe into the hearts of the millions of supplicants below.

Forbidding statues of angels and Primarchs loom down from their eyries, their sightless stare driving out all thoughts of heresy. It is considered such a blessing to set foot upon Holy Terra that most of the pilgrims who manage to reach its polluted surface never leave.

Terra is perhaps the most massive Hive World within the Imperium, with an uncounted population that numbers several hundred billion human beings. The bulk of Terra's massive population is divided between the upper class that includes the Imperial nobility and Adepts of the Adeptus Terra and the masses of the lower classes who serve as basic labourers.

The upper class is comprised of the official servants of the Emperor and His Imperium, including Imperial officials, Ecclesiarchy clergy, the aristocratic families of the Navis Nobilite, military officers, scribes, and bureaucrats.

The teeming masses who comprise the Terran lower classes are far less-privileged, and many of them are nothing more than serfs or thralls who toil in the Throneworld's countless manufactoria, providing the infrastructure that keeps the heart of the Imperium's byzantine bureaucracy functioning. Terra has one moon, Luna, which is an inhabited and highly populous Civilised World of the Imperium in its own right.

Holy Terra

High Orbit Above Terra








A Terran Hive City





Fully half of the Space Marine Legions, the Imperial Army and the ancient Mechanicum threw in their lot with Horus and the other Traitors and for nine standard years they waged a brutal and total war upon the galaxy, leaving countless worlds blazing in thermonuclear fire as they closed in on Terra.


But the Emperor and His Loyalist servants ultimately prevailed, and slew Horus at the height of his power on the bridge of his own flagship, the terrible Gloriana-class Battleship, Vengeful Spirit, in high Terran orbit. But the price was high, for the Emperor was mortally wounded and only survived by having His ravaged body interred within the cybernetic life support mechanisms of the arcane device known as the Golden Throne. Though the Emperor's mind remained fully empowered and active within the Immaterium, he could no longer directly communicate His wishes to those who remained behind to govern His Imperium.

And so for the last 10,000 Terran years stagnation, technologically, culturally and even morally, has come to define the Imperium of Man. The Imperial Truth's official atheism has wilted in the face of the terrible dangers that confront Mankind in the Milky Way Galaxy, replaced by the comfort of a religion that holds that the Emperor of Mankind is the God Incarnate of humanity.


The lucky are able to find work within the bureaucracy of the Imperial Administratum, while the majority are condemned to the poverty and heartbreak of lives as common manufactorum labourers or serfs. In the late 41st Millennium, there is no doubt that Terra will become the scene of Mankind's ultimate salvation at the hands of the Emperor's loyal servants...or the last outpost of humanity to fall before a tide of heretical rebellion, xenos genocide and Chaos damnation.


Age of Terra, M1-M15

Next to nothing is know about Terra's early millennia during the so-called Age of Terra, save that it was between the 1st and 15th Millennia AD that Mankind made their first forays into space, notably colonising Mars. Warp travel was at this point was technologically impossible, meaning most space colonies were self-sufficient and isolated by long, dangerous sub-light speed journeys.

Likewise, not much is known about the Age of Technology and Age of Strife that followed, or why Terra was spared the annihilation that met countless other human-settled worlds. It was at this time that Terra and Mars made ancient agreements that would tie the fates of both planets forever, with Mars at this time a hub of manufacture, scientific research and commerce.

Unification of Terra, Late M29-M30

Towards the end of the Age of Strife -- several thousand standard years during which the first galaxy-spanning empire of Humanity crumbled and fractured into isolated fragments -- the Emperor of Mankind first revealed Himself to Humanity. He began reconquering Terra with an army of Thunder Warriors during the so-called Unification Wars, which were the genetically modified super-soldiers who preceded the Space Marines. The various techno-barbarian empires on Terra were destroyed with this unstoppable army, and the Emperor soon controlled the whole planet -- with designs on taking back the entire galaxy.

The Great Crusade and Horus Heresy, M30-M31

The Great Crusade launched from Terra, which itself became a key battlefield of the Horus Heresy, with the final, climactic conflict seeing the planet invaded en mass by the followers of the Warmaster Horus during the Battle of Terra.

The Beheading, M32

With the Emperor incapacitated during the Horus Heresy, leadership over the Imperium fell to the High Lords of Terra. This did not always go smoothly, such as in the mid-32nd Millennium, when the High Lords were slain by the Grand Master of Assassins, Drakan Vangorich, in an event called "The Beheading" who then ruled the Imperium for solar decades before being deposed by a combined strike force of Space Marines.

The Nova Terra Interregnum, M35-M36

The Imperium was once split in twain by political strife during the so-called Nova Terra Interregnum when the Ur-council of Nova Terra established a second, parallel capital to the Imperium.

The Age of Apostasy, M36

The Nova Terra Interregnum ended, only to be followed by a new schism. Ecclesiarch Goge Vandire struggled for power with the other High Lords of Terra. As tensions escalated, several Chapters of Space Marines assaulted Terra in order to remove the tyrant from office. Vandire was eventually betrayed by the holy military order that would become the Sisters of Battle.

Age of the Dark Imperium, M41-M42

With the opening of the Cicatrix Maledictum following the fall of Cadia in the 13th Black Crusade, the beacon of the Astronomican faltered, and Terra itself was assailed by daemons as Khorne launched a brutal assault on the Imperial Palace known as the Battle of Lion's Gate. A joint force of Primaris Space Marines, Adeptus Custodes and Sisters of Silence repelled the assault, but it stands as a dire warning of just how far the Chaos Gods could reach if the Golden Throne were to fail completely...


Terra&#039;s Landscape

The landscape of Terra in the late 41st Millennium.

The Imperial Palace complex in the Himalazian Mountains of Terra


What remained of Terra's oceans after the thermonuclear wars that scarred the planet during the Age of Strife boiled away in the years after the Horus Heresy due to the immense heat produced by the hundreds of billions of people who have been compressed into the world's limited living space. All liquid water to meet the Terran population's needs is now delivered from orbit by freighters who take large ice-bearing comets from the outer Sol System and bring them into Terran orbit to be melted down and dispersed to the population.

Many mountain ranges have been leveled -- perhaps all but the Himalazian range (the Himalayas), which remain untouched due to the genetic engineering laboratories said to lie beneath them where the Emperor created the Primarchs and the first Space Marines after the Unification Wars more than ten millennia ago.



A square metre of land on Terra costs more than a palace on any other Hive World; only the most wealthy citizens can afford to own a small section of land. Terra's entire surface, with the exception of the Antarctic region, is covered in labyrinthine edifices of state, including the Imperial Palace, the Ecclesiarchal Palace of the Adeptus Ministorum and the many departmental headquarters of the Adeptus Terra, the Imperial government.


Terra was also originally home to the massive concentrations of industry known as "Orbital Plates," which in earlier times were referred to as "space elevators." By the time of the Great Crusade in the 30th Millennium most made use of anti-gravitic technology and no longer had any need to be anchored to the planet's surface.

These orbiting cities were old even in the time of the Unification Wars, but during the Horus Heresy, in the years before the start of the Battle of Terra, the Primarch Rogal Dorn, who had been named Praetorian of Terra by the Emperor and was thus in charge of its defence from Horus' invasion, had them all dismantled, moved, or abandoned over questions concerning their safety and loyalty.

In the 41st Millennium there are still countless orbital defence platforms circling Terra, and the Throneworld is the most heavily fortified and protected planet in the galaxy.

Oceans of Terra


The soaring landscape of Terra's arcologies in the late 41st Millennium.

By the time of the Unification Wars in the early 30th Millennium, there was only one remaining ocean on Terra -- the so-called "Great Ocean" -- which was actually the remains of the ancient Pacific Ocean. The size of the Pacific was vastly smaller than in prior eras, due to the vaporisation of a massive stretch of the ocean during the nuclear wars that had consumed much of Old Earth in the lost years of the Age of Strife.

This missing portion of the Pacific stretched from the Marianas Trench down past Australia and all the way to the frozen continent of Antarctica. The Atlantic Ocean had also been largely vaporised as the great body of water that had once been near Europe was now mostly gone, particularly to the south of what had been the Iberian Peninsula.

Other, smaller, bodies of water may still have remained during this time, as a great sea is recorded to have been present in the region of Eurasia where the Caspian Sea had lain in ages past. These bodies of water still existed at the start of the Horus Heresy in the early 31st Millennium, but by the time of the 41st Millennium, Terra had no free-standing bodies of water, having become a true ecumenopolis, a world completely covered by the dense urban areas of massive hive cities.

The Emperor had sought to create artificial bodies of water to replace what had been lost in the wake of the Unification Wars, but by the 41st Millennium, no liquid water was visible on Terra's surface. Within these human hives toiled the tens of billions of Adeptus Terra bureaucrats and serfs required to keep the decaying heart of the Imperium of Man pumping.

Notable Locations


Imperial Palace Terra2

The Imperial Palace on Terra.

Eternity Gate

The Eternity Gate, portal to the Emperor's inner sanctum

  • Eternity Gate - The largest entryway into the Inner Imperial Palace's Sanctum Imperialis. A mile-long passage leads to the Eternity Gate, lined with the banners of thousands of the greatest and long-dead Imperial heroes, including Lord Commander Solar Macharius. It constitutes the end of the galactic pilgrimage trail or the devotees of the Imperial Cult, and is itself the most important pilgrimage site in the entire Imperium, for almost no one is ever allowed entrance through the Eternity Gate into the Sanctum Imperialis.
Sanctum Imperialis 2


  • Sanctum Imperialis - The Sanctum Imperialis is the throne room and heart of the Imperial Palace. It is the massive chamber housing the Golden Throne and the Emperor's physical body. It is guarded by a select group of three hundred Adeptus Custodes, the Companions, who are the elite among the elite.
    • Central Offices of the Departmento Munitorum - These offices mark the central location of the Departmento Munitorum, a department or sub-division of the Adeptus Administratum devoted to the general administration, personnel assignment, supply and logistics of the Astra Militarum.
    • House of Weapons - The House of Weapons is the ancient, formidable armoury of the Imperial Palace. The Adeptus Custodes and the Imperial Fists Chapter are known to store their arms and armour here.
    • Obsidian Keep - The Obsidian Keep is the current headquarters of the Adeptus Astra Telepathica in the 41st Millennium. Located in the vast Astra Telepathica palace complex on Terra, some psykers captured by the League of Blackships are brought here for training as Astropaths or Sanctioned Psykers.
    • Bhab Bastion - The Bhab Bastion was an ancient place of counsel and refuge for warlords and tyrants since before the Age of Strife. Following the Unification Wars, this ancient structure was absorbed into the growing complex of the Imperial Palace. During the Horus Heresy, the Bhab Bastion, alongside the Phalanx, the massive capital ship of the Imperial Fists Chapter, acted as the command centre of the Primarch Rogal Dorn while he oversaw the construction of the defences for the Sol System as the Warmaster Horus' Traitor Legions closed on the Throneworld.
    • The Shrouds - The Shrouds is the name given to the secret chamber located deep within the confines of the Inner Palace that served as the headquarters of the Officio Assassinorum. It was the primary meeting place of the various masters of all six Assassin Clades and was overseen by the Grand Master of Assassins. During the Great Crusade and Horus Heresy eras, this post was held by Malcador the Sigillite.
    • The Pillar of Bone - The Pillar of Bone is believed to be a monument raised on Terra to the Imperial Fists' courage in an unnamed campaign. In reality it is actually a sacred relic to those privy to the truth about the Chapter within the Imperial Fists. The Pillar is the last remnant of the once-great Imperial Fists fortress-monastery that stood on Terra. It was destroyed during the Horus Heresy in the midst of the Battle of Terra.
    • The Investiary - The Investiary was a massive amphitheatre open to the night sky, its broad space once containing the statues of the twenty Primarchs on ouslite plinths in a silent ring. The effigies of the traitorous Primarchs who betrayed the Emperor during the Horus Heresy were once temporarily shrouded. Following the end of the Horus Heresy, the effigies of the Traitor Primarchs were removed entirely.
    • The Senatorum Imperialis of the High Lords of Terra - This immense building within the Imperial Palace complex houses the council or Senatorum Imperialis of the twelve highest-ranking political officials in the Imperium, the High Lords of Terra, who rule in the Emperor's name as He no longer can, though His mind is believed to remain active in the Warp, guiding and protecting humanity.
      • Great Chamber of the Senatorum Imperialis - This massive meeting chamber is where the Imperial elite hold their "parliament," and is the meeting place of the High Twelve.
    • Library Sanctus - The Library Sanctus is an Imperial archive located on Terra. It holds knowledge of some of the oldest and most sinister things in galactic history, such as information on the Men of Iron and the Ymga Monolith.
    • Dark Cells - The Dark Cells or "Black Cells" as they are sometimes called, are shadowy oubliettes located deep beneath the Imperial Palace that contain entities and aretfacts that date back to the Age of Strife that could be used to annihilate the Imperium itself if they were to break free or be used by those with nefarious purposes. It is unknown if the Dark Cells are the same location as the Vaults of Rython that were used for an identical purpose by the Legio Custodes before the Horus Heresy. Guarded by the Shield Host of the Adeptus Custodes known as the Shadowkeepers, the technology used to keep them sealed includes runic locks, psychic wards and sanctic circles. The corridors of the Dark Cells are patrolled at all times by a hundred Custodians of the Shadowkeepers. Although neither light, nor sound can escape from the cells, the dread air surrounding the facility is capable of even putting the iron-willed Custodians on edge.
  • Adeptus Terra - The Adeptus Terra, known commonly as the Priesthood of Earth, is the actual government of the Imperium of Man, consisting of countless different bureaucratic organisations and the departments within them. Besides the vast, destitute population of non-Adepts that makes up the majority of the planet's populace, much of the rest of Terra's population are members of the Adeptus Terra and of these the largest percentage are Adepts of the Administratum.
  • Administratum - The Administratum is the administrative and primary bureaucratic division of the Adeptus Terra. It consists of untold billions of clerks, scribes, bureaucrats and administrative staff constantly working to manage the Imperium at every level, from assembling war fleets to levying taxes and tithes. It is the largest of the departments comprising the Adeptus Terra, and ten billion Administratum Adepts work in the Imperial Palace alone.
  • The Forbidden Fortress - The Forbidden Fortress is a vast complex that extends throughout the mountain range of the Himalazians. A single peak is carved to form the Chamber of the Astronomican, where ten thousand psykers continuously power the Astronomican beacon directed by the mind of the Emperor with their own life energies. The "psychic light" of the beacon reaches thousands of light years across the Warp and helps to keep the daemonic entities of the Warp from breaking through the dimensional barrier into realspace. The Astronomican is utilised by the mutant psykers known as Navigators to guide interstellar starships through the otherwise trackless chaos of the Warp. Without it, long-distance Warp travel would be impossible and the Imperium of Man would disintegrate. Access to the Forbidden Fortress is restricted to invitation only. This includes even members of the Inquisition who must still request access.
  • Fortress of the Inquisition - The Inquisition's headquarters on Terra is a sprawling and highly secure complex built beneath the south polar ice cap of Antarctica. Located deep underground, this subterranean complex is heavily warded and equipped with psyker dampening devices and null-fields. Only members of the Inquisition and a sparse number of prisoners are permitted to enter this underground complex. The Fortress is overseen by a senior Inquisitor known as "The Castellan," a position which changes annually, to ensure that no man or woman can establish a political powerbase or extend the control of one of the Inquisition's innumerable quarreling factions over this facility.
  • Navigator's Quarter - The headquarters of the families of the Navis Nobilite (the Navigators). It is said to be located on a massive island.
  • Hall of Judgment - The headquarters of the Adeptus Arbites, the chief law enforcement organisation of the Imperium.
  • Officio Assassinorum and the Assassinorum Temple - Although its agents operate throughout the Imperium, this dark organization is based on Terra. Its School of Assassins and most of the temples that comprise the Officio are said to be located on Terra, although their actual locations are closely guarded secrets. The Assassinorum Temple is specifically the headquarters of the Grand Master of Assassins.
  • Adeptus Astra Telepathica - The Adeptus Astra Telepathica is the organization responsible for recruiting and training officially-sanctioned psykers for service to the Imperium. The infamous Black Ships of the Adeptus Astra Telepathica travel throughout the Imperium, gathering their tithe of psykers and returning with them to Terra. The psykers are analysed and sorted according to their psychic power and strength of mind in resisting the temptations of Chaos. The novitiates are trained at the Scholastica Psykana for five standard years before being sent for further training elsewhere. Some of these Sanctioned Psykers become Astropaths, specialist psykers who are trained to telepathically send and receive messages over interstellar distances (no other form of instantaneous interstellar communication exists). Others are requisitioned by the Adeptus Astronomica for service in the Astronomican's choir. The most powerful, those who demonstrate a strong enough mental character to resist daemonic possession on their own, often enter the Inquisition for training as Acolytes, with some eventually becoming Inquisitors themselves. Those psykers deemed too weak or dangerous to live become sacrifices to the Emperor; their souls are "fed" into the arcane technology of the Golden Throne so that the Emperor may continue to live and guide the Astronomicon that allows the Imperium to function as an interstellar civilisation. Only psykers that have been trained at the Scholastia Psykana are legally sanctioned by the Imperium; all others are considered illegal, often branded as "witches," and are at risk of being summarily executed as Heretics by the Inquisition's Ordo Hereticus and other organs of official Imperial power.
  • The Ecclesiarchal Palace - The headquarters of the Ecclesiarchy, also known as the Adeptus Ministorum, the Ecclesiarchal Palace sprawls over almost the entirety of Terra's southern continent of Australia. It is also home to one of the two major convent-fortresses (the Convent Prioris) of the Adepta Sororitas (the Sisters of Battle) on the Imperium's Throneworld.
    • The Cathedral of the Emperor Deified - A massive cathedral of the Imperial Cult that was built near the Ecclesiarchal Palace.
    • The Cathedral of the Saviour Emperor - A large cathedral of the Imperial Cult that is quite popular amongst pilgrims. It is said to contain important Imperial relics, including pieces of the Emperor's armour and ashes from the cloak of Roboute Guilliman, the Primarch of the Ultramarines and current Lord Commander of the Imperium. Pilgrims often undertake multi-year journeys to the Cathedral and endure massive lines, only to be granted a mere three solar seconds to be in the presence of these holy relics before they must take their leave and move on.
  • Khangba Marwu - Khangba Marwu, also known as "The Vault," was a large underground Imperial prison complex on Terra intended to hold the worst criminals of the Imperium of Man. Its inmates were overseen by the Legio Custodes during the early 31st Millennium. The prison was located in the Himalazian Mountains under the mountain peak of Rakaposhi, and had been constructed at least a thousand standard years before the Horus Heresy began by persons unknown. The prison was home to some of the worst criminals of the Imperium and had been used to imprison several of the tyrants defeated by the Emperor's forces during the Unification Wars.
  • Eternal City - The Eternal City is a massive urban area adjacent to the walls of the Imperial Palace in the 41st Millennium that is known to contain both great splendour and horrible squalour, making it a microcosm of Terra itself.
  • The Catacombs - The Catacombs are vast underground passages which run beneath Terra, so large that they require oversight by a designated Imperial official known as the Mistress Plenary who is a lesser member of the Senatorum Imperialis, serving at the pleasure of the High Lords.
  • Hive Karelia - This ancient city once housed a vast library that contained knowledge of the Dark Age of Technology, but was bombed by Pro-Panpacifists during the Great Crusade era, due to civil unrest and resistance to the Emperor's rule. It had been scheduled for demolition, but Kasper Ansbach Hawser, an Imperial Conservator (historian), managed to succeed in recovering over 7,000 texts from a data archive that had been deemed worthless.
  • Hive Tashkent - Hive Tashkent is one of the hive cities of Terra known to exist in the 32nd Millennium at the time of the War of the Beast. It is based on the continent of Asia.
  • Himalayic Shelf - Deep beneath this geological construction live the deadly denizens of various rune-locked vaults. The warriors of the Adeptus Custodes often fight in skirmishes intended to prevent them from escaping.
  • Manufactora Mericum - Beneath this massive manufactorum complex lie countless tunnels that are used as hiding places for various cults. The warriors of the Adeptus Custodes sometimes enter them to carry out a purge of the cultists when the threat they present begins to grow.
  • Walking City - The Walking City was a densely-populated, mobile techno-nomad platform that slowly walked a looping route towards the equator of Terra and back on twenty great legs. During the Horus Heresy, in the days just before the start of the Siege of Terra, the Walking City came under assault by the daemon known as the Lord of Flies, which had used the potent faith of a secret church dedicated to the then-illegal cult of the God-Emperor as a way to manifest in the material realm. The daemon had infected the population, transforming them into plague fly-riddled zombies. The Knights-Errant, led by Nathaniel Garro, were despatched to combat the attack and successfully banished the Chaos infestation.
  • White Mountain - The White Mountain was a great subterranean fortress delved beneath a mountain range on Terra. It had been constructed by one of Terra's ancient and unknown warlords and lay in a region that by the time of the Horus Heresy was still irradiated and lifeless from the damage caused to the world by the Age of Strife. The fortress had been taken over by the Imperium and had potent anti-psyker wards put in place so that it could serve as a prison for psykers. The Emperor's intent had been to imprison the potent psychic Primarch Magnus the Red there if he had been successfully extracted from Prospero. Unfortunately, the Space Wolves had attacked that world early in the Heresy against the Emperor's original orders and Magnus had gone over to the service of Chaos, never returning to Terra. The White Mountain was where Malcador the Sigillite ordered a group of Sisters of Silence who had been captured and tortured by the forces of Chaos and then recovered by the Loyalists to be held while his researchers sought to determine what had been done to them. In fact, the altered Sisters were simply part of a plot by the Traitors to assassinate the Sigillite by triggering a subliminal mental command that had been psychically embedded in the mind of Tylos Rubio by the Word Bearers First Chaplain Erebus. Rubio was one of Malcador's Knights-Errant who had fought at the Battle of Calth. The plot was initiated when the White Mountain came under assault by Chaos Cultists and the daemon of Nurgle known as the Lord of Flies. The Knights-Errant were deployed onto the slopes of the fortress to deal with the assault, while Rubio's mental conditioning was triggered by the Sisters of Silence kept within the White Mountain's holding cells. He attacked Malcador while the Sigillite was bereft of his psychic powers due to the fortress' anti-psyker technology. The Sigillite managed to hold off the attack using his hidden Conversion Field and then psychically stripped the mental conditioning from Rubio's mind. On the slopes of the White Mountain, Garro and the Knights-Errant managed to defeat the Chaos assault, though the Knight-Errant and former World Eater Macer Varren was possessed by the Lord of Flies before finding the willpower to force back the daemon's assault and destroy himself using a brace of grenades taken from Garviel Loken. The daemon's hold on realspace was finally destroyed by the Sigillite himself, who used his restored psychic abilities to burn the daemon to ash.


As the Throneworld of the Imperium, Terra is the most heavily defended world in the galaxy. As Terra itself had faced few true threats in the ten thousand years since the end of the Horus Heresy, even the idea of attacking the planet has been seen as ridiculous by many Imperial officials throughout history.

However, the world has always been protected by a multitude of layered defences drawn from every branch of the Imperial military. These include, but are not limited to, the following:

Golden Throne





Terra and Luna

The name Terra originates from the ancient Terran language known as Latin which translates as "earth; land"; it is the name of Earth in many modern day Romance languages descended from Latin.
