Oldcorne Sector

Imperial worlds: 84
Sector capital: Doveron Tertius
Subsectors: Doveron, Basildon, Chelm, Sillon, Vranum, Ballinus.
Imperial supremacy grade: Medium

The Oldcorne sector is currently in a process of rejuvenation as it is rebuilt after the ork attacks that spread in the Esquiline Quadrant through the Cruciatine sector. It is going through a period of economical and political optimism and while the Imperial armies and fleets are not yet in a position of absolute dominance in the sector, it is only a matter of time before the last ork empire fragments are annihilated. The rapid rebuilding effort in the Oldcorne sector has led to a unique situation however. Merchant Guilds and trade syndicates are becoming very influential through partly funding the restoration of Imperial colonies and thus gaining a unique position as far as shaping the Oldcorne sector. Across many subsectors, the power of the Imperial nobles is dwindling while the Merchant Guilds are rising. The Adeptus Administratum has expressed great concern about this development, but if the Imperium hopes to rapidly rebuild the Oldcorne sector, it must either suffer the influence of the Merchant Guilds or consider the politically dangerous option of simply confiscating the resources of commercial organisations without offering political power in return.

Significant locations


  • Doveron Tertius: The once invaluable hiveworld Doveron Tertius suffered a massive ork infestation after a global invasion in M37. The struggle to exterminate the orks has been extremely difficult due to the rich ecosystem on Doveron Tertius’ surface, combined with a rich soil and large number of underground caves in which the orks spawn with great speed.
  • Forgeworld Neru: The forgeworld Neru was completely lost to the orks during the past ork invasion. Some humans do linger in the midst of the invading ork civilisation, surviving in wastelands and underground networks, but the forgeworld is considered ork territory and classified as ‘Perdita’.

Herluin Sector

Imperial worlds: 102
Sector capital: Malandra
Subsectors: Prakesh, Oxamius, Maliopos, Candiatum, Shinai, Phemineus
Imperial supremacy grade: High

Lying directly coreward of Anargo, the Herluin sector is an important source of trade and traffic to the Anargo sector. Every year, thousands of ships pass through the sector via the Flavonian course, sailing between the Segmentum Solar and Ultramar. Like the Anargo sector, the Herluin sector is closely watched by the Imperium, as the strategic value owed to the Flavonian course is tremendous. The most significant events in the Esquiline Quadrant, such as the Great Crusade, the Horus Heresy and the Liberation of Saint Thor, have begun in the Herluin sector and spread through the Anargo sector to the rest of the Esquiline Quadrant. At present, the Herluin sector is politically and economically stable, with no significant internal or external threats. Like the Anargo sector, the Herluin sector is arguably quite representative of the Imperium as a whole, in many ways.

Constabilis Sector

Imperial worlds: 97
Sector capital: Corona Prime
Subsectors: Constabilis, Velum, Lynceus, Genloch
Imperial supremacy grade: High

With close to a hundred worlds divided between only four subsectors, the Constabilis sector is made up from dense clusters of Imperial colonies, surrounded by large tracts of wildspace with little or no Imperial presence. Never the less, the Imperium maintains a tight grasp on the Constabilis sector. No major incursions or rebellions have taken place in the sector for millennia and due to the close proximity to the Flavonian course flowing through the nearby Herluin sector, the Constabilis sector enjoys great amounts of intersector trade. Having climbed to a golden age of prosperity, the Constabilis sector is preparing the colonisation of the Convall Cluster, what might grow to become the fifth subsector of Constabilis.

Validus Sector

Imperial worlds: 127
Sector capital: Validus IV
Subsectors: Arius, Mun, Intip, Cerbant, Ketheria, Bolev
Imperial supremacy grade: High

The location of a substantial human Empire that was easily brought into the Imperium during the Great Crusade, the Validus sector contains the highest number of pre-Imperial colonies in the Esquiline Quadrant.  Through a stable warp current known as the Menecles Vein, many ships from the northern regions of the Ultima Segmentum arrived in the Validus sector during the Age of Technology. The compliance of the Validus sector by Primarch Alpharius during the Great Crusade was one of the biggest victories in the Esquiline Quadrant, and for millennia to come the Validus sector was the political heart and economic powerhouse of the Quadrant.  It was the vast coordinated military might of the Sector that ensured the eventual breakup of Waaagh! Tuskragga in M36. Since that time the sector has supplied numerous regiments to patrolling and suppressing further Ork activities in Cruciatine. It also played a role in supporting the Thorian idealists in Anargo after the fall of its own pro-Vandire leadership in the Age of Apostasy.

As time has passed the Menecles Vein has slowly waned in strength, resulting in less traffic to the Validus sector and since the Age of Apostasy, the Validus sector has stagnated.  Its ancient Merchant Guilds and noble houses have grown increasingly powerful, while the smaller fish seek fortune in other sectors.

Ordo Xenos Inquisitors believe that the Eldar loyal to the Craftworld Luggannath may be travelling through the unexplored Cairnech Cluster.

Subsectors

Arius: As the sector's political, economic and military centre, the Arius subsector functions as a hub for the other subsectors. Raw materials, industrial products, foodstuffs and millions of people are imported into Arius from the surrounding subsectors. Due to it's central position the Arius subsector has been used as a main port location for economic trade with the Anargo Sector which is connected with the Flavonian Course and with other Sectors along the Menecles Vein

Mun: Mun can be seen as the breadbasket of the Validus sector, agriworlds from the Mun subsector produce vast amounts of agricultural products which are exported throughout the Esquiline Quadrant.

Intip: Similarly to Mun Intip is produces large quantities of foodstuffs for the Validus sector.  In addition Intip supplies vast amounts of human resources for the Imperial Guard and Navy.

Cerbant: The Cerbant subsector exports raw materials and mass produced goods to the Arius subsector where they are either processed for local consumption or prepared to be exported to the Anargo Sector.

Ketheria: A mixed subsector with many civilized worlds as well as agriworlds and mining worlds,   Ketheria produces large amounts of raw materials.  In addition Ketheria supplies thousands of Imperial Guard regiments which are shipped to the Arius subsector from where they are deployed throughout various battlefields in the Esquiline Quadrant.

Bolev: The sector's main producer of military hardware the Bolev subsector exports vast amounts of weapons, vehicles and other goods to the Arius subsector where they are distributed amongst the many Imperial forces present there. In the recent years various worlds in the Bolev subsector have been under attack by xenos raiders, primarily Eldar Corsairs and Orks.

Significant locations


  • Cairnech Cluster: A region of dense stars, gas and dust that has remained unexplored since the Dark Age of Technology.
  • Xiphon: The hiveworld Xiphon in the Bolev subsector is Validus' main producer of military hardware. Thousands upon thousands of tanks pour out it's factories every year, providing the Imperial Guard with the armour they so dearly need.

Relations with Anargo

The Validus sector exports vast amounts of mass produced goods and agricultural products to the Anargo sector from where they can be exported to other areas using the Flavonian course. Due to it's stability Validus is able to sent out vast amounts of military forces to the surrounding sectors, it is for this reason that many regiments from the Validus sector are stationed in the Anargo sector. The Anargo sector is not only a battlefield for these forces but also a hub from which they can move to other sectors using the Flavonian Course.

Military forces

Imperial:
Imperial Guard: The many, large populous worlds of Validus raise numerous regiments of Imperial Guard that are sent to warzones hundreds of light-years away. They are currently reinforcing the few remaining Imperial worlds in the Cruciatine sector.

Non-Imperial:
Eldar Corsairs: The Luggannath Craftworld is suspected of deploying Corsairs through the Cairnech Cluster from where they carry out raids against Imperial transports from the Bolev subsector.

History

Great Crusade: Before the arrival of the Emperor's armies during the Great Crusade the Validus sector was home to a relatively large and powerful human empire. This ruler of this empire, a psyker, had visions of mighty warriors who were all identical saving the empire from a foul threat. These visions became truth when Ork forces started to pour into various worlds of the empire. What the ruler didn't know though was that the Orks were forced to retreat into the empire by crusading Alpha Legion. The warriors of Alpharius had been wiping out various Orks held worlds along the Flavonian Course and while many Orks simply faced these mighty warriors in battle, many simply fled to fight battles against weaker opponents.
When the Orks finally arrived in the Validus sector, the humans stood no real chance against their might. Having sensed this opportunity, Alpharius offered the empire of Validus salvation in return for submission to the Imperium. The Orks were quickly defeated and Validus was easily integrated into the Imperium.

Horus Heresy: After the annexation of the human empire the Alpha Legion forces quickly moved on into the Anargo sector and other sectors which were more difficult to conquer, what this meant for the Validus sector was that it remained relatively unaffected by the Horus Heresy. Forces from Validus poured into the surrounding sectors supporting loyalist forces against the traitors.

Age of the Imperium: In the years after the Horus Heresy Validus kept it's role of supporting the Imperial war effort throughout the Esquiline Quadrant. Various regiments of the Imperial Guard were sent from the spaceports in the Arius subsector to the Anargo Sector to fight in the so-called "Xenos Wars" in which various alien species were exterminated. In M36 millions of Imperial Guardsmen and elements from Battlefleet Validus were responsible for the collapse of Waaagh! Tuskragga.

Age of Apostasy: Thorian forces from the Validus sector waged a long and bloody battle against the pro-Vandire forces. When the armies loyal to Vandire were finally defeated the Thorians moved into the Anargo Sector, supporting the Thorian idealists in their war against the followers of Vandire.

Dark Millennium: After the Age of Apostasy Validus remained a stable sector, providing military support to it's surrounding sectors. The greatest example of this feat is probably the fact that the Imperial forces from Validus are the sole reason why the Cruciatine sector is still under human control. However, the Bolev subsector has weakened due to increasing xenos raids. Eldar Corsairs loyal to the Craftworld Luggannath have been carrying out raids against transport ships. Battlefleet Validus has been deployed to solve this matter.

Revocatus Sector

Imperial worlds: 98
Sector capital: Revocatus Prime
Subsectors: Revocatus, Aventine, Samvara, Fallon, Duquesne
Imperial supremacy grade: Medium

Like the Anargo Sector the Revocatus Sector was conquered by Imperial forces lead by the youngest Primarch Alpharius. After the Horus Heresy the Ultramarines and Adeptus Mechanicus were crucial for the rebuilding of the sector. Because the Revocatus sector is not connected with Flavonian Course it has become very dependent on those sectors which are connected to it for trade. Before the Aventine Heresy in M40 the factory worlds of Revocatus exported large numbers of industrial goods, both civilian and military to the Anargo Sector. After the Age of Apostasy it was partly the Revocatus sector that has been responsible for the economic growth of the Meksum subsector.

The Mechanicus Priests of the Revocatus Sector have been keen to gather support from neighbouring forgeworlds to lead an expedition into the Lazarus Sector to secure the factory world of Ytha. However, to date their efforts to gather an Explorator Fleet and troops have been unsuccessful. This is mainly due to the betrayal of the Aventine subsector, where a total of eighteen colonies were corrupted by the Alpha Legion and remain in the control of Chaos forces.

Subsectors

Aventine: The Aventine subsector in itself produced very little compared to the other subsectors of the Revocatus sector, it's importance lay in the fact that there are several large spaceports located on some of the worlds which are used as economic hubs from which goods are imported and exported from and to the Anargo Sector. While a prosperous subsector, not many of it's population receive anything from it's wealth meaning that the majority of the population there live in heavy poverty. This miserable situation in which many people lived proved to be fertile grounds for the Alpha Legion to plant their seeds of rebellion.

Samvara: Samvara is a heavily industrialised subsector and is the sector's main producer of military hardware, be it in the form of light weapons by infantry to the powerful battletanks such as the Leman Russ which dominate battlefields throughout the area.

Fallon: Like Samvara the Fallon subsector is an industrial hub, the only difference is that Fallon is mainly focussed on the production of spaceships and other equipment and parts used for those. The hiveworld Fallon Prime is the home of Battlefleet Revocatus.

Revocatus: The sector's political and religious capital lies in the Revocatus subsector. The capital world of Revocatus Prime is a divided world. While the rulers of this world and the sector are appointed by the High Lords of Terra, the Ecclessiarchy has been trying to increase their influence over the sector for millennia. 

Duquesne: Similar to the Archaios subsector in the Anargo sector the Dunquesne subsector has a very strong Adeptus Mechanicus influence. From the forgeworld Atres III the worshippers of the Machine God have practically full control of this subsector. This has given the Adeptus Mechanicus a powerful position within the sector because they are the main producers of foodstuff for the Revocatus sector. The knight worlds controlled by rulers of Atres III produce vast quantities of agricultural products which are not only exported to the rest of the sector, but also to the Anargo sector.

Significant locations


  • Halocene Asteroid Field: This field, located in the Samvara sub-sector, is thought to host as many seventeen pirate fiefdoms. Some of these pirates have joined the traitors in the Revocatus subsector. However, most have remained neutral and attack both sides of the conflict and are known to use the civil war for their own profit.
  • Fallon Prime: This naval base represents the strongest concentration of Imperial power within the sector. Battlefleet Revocatus docks here, but is remarkably under-strength. If there is any hope for Revocatus, it resides here.
  • Revocatus Prime: The sector's capital, the spiritual and political heart of the Revocatus sector. However, due to a struggle of power between the local rulers and the Ecclessiarchy it has been unable to effectively wage a counter offensive against the rebels in the Aventine subsector.
  • Aventine subsector: A subsector functioning as the Revocatus sector's main economic hub it finally rebelled in M40 causing the Revocatus sector to be trapped in a bloody civil war.

Relations with Anargo

Large amounts of mass produced goods were imported into the Anargo sector from Revocatus. These goods were then exported from the Anargo sector to other sectors using the Flavonian Course. Mainly the Meksum subsector in the Anargo sector and the Aventine subsector in the Revocatus sector profited from this trade. It is partly due to this trade between the sectors that Meksum has been able to become so powerful over the millennia.

Because of the Aventine Heresy the Revocatus sector has been completely isolated from the Anargo sector, making trade impossible due to the naval blockade created by the traitor forces. Occasionally Imperial forces in the form of the Maledictors or Battlefleet Anargo attempt to break through the blockade with no real success due to the fact that their forces are needed in the Sargassos and Castellan subsectors.

Military forces

Imperial:
Imperial Guard: All Imperial Guard regiments within the Revocatus sector are constantly fighting the forces of the Aventine subsector. For now they hold out, but if a large amount of reinforcements do not get through soon Revocatus’ fate cannot be assured.

Battlefleet Revocatus: There is a naval base in the Fallon subsector, which hosts the remarkably small Battlefleet Revocatus. The fleet have nothing significant enough to match the threat of Aventine and spend the majority of their time directly escorting ships along trade routes.

Knight Households of the Duquesne subsector: The Adeptus Mechanicus have deployed their Knights to protect the worlds which they are still holding. On occasions invasions are carried out in traitor held territory which from time to time are successful.
 
Non-Imperial:
Alpha Legion: A relatively large force of Alpha Legion Space Marines are carrying out attacks throughout the Revocatus sector. It were they who supported the local population of the Aventine subsector to rebel against their oppressive rulers.

Traitor Guard: All the worlds fallen to the Alpha Legion are now raising regiments to attack the rest of the Revocatus Sector. With access to military hardware from the conquered industrialised worlds the Traitor Guard forces of Aventine are more than a match for the Imperial Guard.

Chaos Raiders: These pirates loyal to the Alpha Legion have been able to isolate the Revocatus sector from Anargo not only by guarding the borders but also by occasionally carrying out pirate raids against ships in the Anargo sector. Khornate pirates carried out an attack on the world of Ludov where they introduced a xenos lifeform which causes major problems even many years after the invasion.

Orks: The original inhabitants of the Revocatus sector, the Orks have been driven off their worlds. Lonely pirate fleets still exist but they pose no major threat to the Imperium.

History

Great Crusade: Under the leadership of Alpharius the Alpha Legion and forces of the Imperial Army moved across the Flavonian Course to liberate planets in the name of the Emperor. However, they did not simply move straight along the Flavonian Course but also spread around to the surrounding sectors. Before the arrival of the Emperor armies the Revocatus sector was terrorised mainly by Orks and human worlds which have fallen into madness during the Age of Strife.

Horus Heresy: Like in the rest of the Imperium the Revocatus sector turned to civil war in which millions upon millions lost their lives. Forces loyal to the Alpha Legion carried out genocidal campaigns in an attempt to exterminate everybody who stood in their way.

Age of the Imperium: With the arrival of the Ultramarines the Revocatus sector was liberated from the bloodthirsty forces loyal to the traitor Primarch Alpharius. Supported by the Adeptus Mechanicus the Revocatus sector quickly turned into a major industrial hub capable of exporting goods to the Anargo sector which where they were then exported to other sectors through the Flavonian Course.

Aventine Heresy: During the last millennia the Aventine subsector became very wealthy due to it's relative closeness to the Anargo sector. While the subsector's elites profited from this position, the majority of the population did not. Slavery, starvation, misery and sickness were the norm for most people living in the Aventine subsector. The Imperium did not care for the Aventine subsector was productive. For a long time the Aventine subsector remained stable through the oppressive rule of the local rulers, this however changed in M40.281 when the population of various worlds simultaneously rebelled and killed their ruling classes. It quickly became evident that the Alpha Legion have offered their support for this rebellion which became known as the Aventine Heresy. Before the Imperium could respond the rebels manage to isolate the Revocatus sector from the Anargo sector and thereby practically destroying it's economy. Slowly having conquered some worlds in the Fallon, Samvara and Duquesne subsectors the rebels had the productive capabilities to wage a war against the Imperium. While successful in their first stages of rebellion the traitors have not been able to win the war. The current situation is that the Revocatus subsector is in a closely tied civil war with no clear victor on either side.

Karlow Sector

Imperial worlds: 105
Sector capital:
Subsectors:
Imperial supremacy grade: High

As the staging point of the recently concluded Ardus Crusade, the Karlow sector is in a period of restitution as it recovers from economical exhaustion. Many of its worlds have been all but drained of reserve resources and their armed forces almost depleted, while the sector’s merchant fleet is reduced by the fact that many transports were drafted into military service by the Navis Imperialis. While the Karlow sector is recovering, it is still a sector of great stability and prosperity, enjoying great cooperation and trade with other sectors in the Esquiline Quadrant. Many Administratum analysts speculate that the current crisis will be followed by a tremendous economical boom, propelling the Karlow sector to new heights.

Significant locations


  • Valentia IX: The renowned fortress world from which Warmaster Ezekiel Morenum launched the Ardus Crusade into the xenos-contested Anitas Quadrant.
  • Fulmenum Shard: A large asteroid investigated by the Sororitas Order of the Unyielding Flame for xenos artefacts.

Significant factions


  • Order of the Unyielding Flame: A non-militant Adepta Sororitas Order specialising in the investigation of extinct xenos and studies of xenos languages.
  • Apogee Ring: A growing xenos cult worshipping the dark eldar as supremely enlightened beings and hidden masters of the galaxy.

Kenan Sector

Imperial worlds: 113
Sector capital:
Subsectors:
Imperial supremacy grade: High

Much like the Anargo sector, the Kenan sector was dominated by a powerful religious government during much of the Age of Apostasy. Unlike the Anargo sector however, the effort to rid the Kenan sector of the old leadership proved a great challenge. After a hard-fought victory, the Imperium managed only to drive the pro-Vandire government underground. Even several millennia later, the descendants of the sector’s old rulers persist in spreading propaganda and starting rebellions and separatist groups. The Kenan sector, while relatively stable and prosperous on the surface, struggles with an underlying political and religious conflict that has progressed steadily for millennia.

Udalrich Sector

Imperial worlds: 119
Sector capital:
Subsectors: Udalrich, Angelus, Varnadan, Munidov, Immanis
Imperial supremacy grade: High

A sector periodically plagued by warp storms, the Udalrich sector is a testament to Mankind’s ability to grow stronger from adversity. The warp storms in the Udalrich sector are highly unpredictable, but one of the most important factors is the vortex created by the opposite currents of the Flavonian Course in the Kenan sector and the Sarmata Gust on the far side of the Udalrich sector. In spite of the frequent warp storms, the Imperial colonies in the Udalrich sector have thrived even in periods of great isolation. More than in any other sector of the Esquiline Quadrant, the Imperial worlds in the Udalrich sector have developed a state of self-sufficiency, hardly relying on imported goods at all. As a necessary consequence, there are very few specialised worlds such as hiveworlds and agriworlds in the Udalrich sector.

Significant locations

Shakti Canton: A cluster of five systems in the Varnadan subsector populated almost exclusively by the Shakti ab-humans. The unique survivability of the Shakti, together with their historical loyalty to the Emperor, has made the Adeptus Terra tolerate their unusually strong and independent position in the Imperium of Man. There are many forces, however, who view this as dangerous hypocrisy and who have taken it upon themselves to destroy the Shakti.
