Founding

"Such is the woe cast upon the Domains of the God-Emperor of Mankind in these times that in their wisdom and beneficence, the High Lords of Terra have this day issued this decree: Let there be a Founding of the Adeptus Astartes, and let the foes of the Emperor know that this galaxy belongs to Him, now and forever."

— High Lord Tagus, Convenor of the 349^th Congress of the Imperium

Most new Space Marine Chapters are not created piecemeal as required by the Imperium of Man's strategic needs, but rather in deliberate groups called a "Founding."

The process by which a new Founding's creation is approved by the Imperial government is mysterious and arcane, subject to solar decades or even standard centuries of planning before it is announced.

It is only by an edict of the High Lords of Terra that such an undertaking as the creation of new Chapters can be instigated, for it requires the cooperation and mobilisation of countless divisions within the Imperium's monolithic and vast governmental organisations. Establishing new Astartes Chapters on an individual basis is nigh impossible -- the mobilisation of such vast resources is beyond the ability of any single segment of the Imperium.

The Adeptus Mechanicus plays an essential role in the process of a Founding, for its highest echelons are tasked with creating, testing and developing the gene-seed samples that will provide the genetic foundation of the new Chapters. Entire Forge Worlds may be turned over to the manufacture of the mighty arsenal of weaponry, ammunition, power armour, vehicles and starships that any such force will require.

There are a myriad other concerns as well. A suitable homeworld inhabited by Humans must be identified for the new Chapter, which will likely provide not only a secure and defensible base of operations, but also a source of new recruits as well. Such worlds might have been reported by itinerant Rogue Traders and earmarked centuries before by Adeptus Mechanicus Explorators as potential Astartes homeworlds.

A degree of environmental terraforming might be required and the natives of the world (if they are to become the source of the new Chapter's aspirants) must be studied and tested by the Mechanicus' Magi Biologis and Genetors for many generations to ensure they are genetically pure and free of any strain of genetic mutation that might later affect the Chapter itself.

The construction of a Chapter's fortress-monastery may be one of the greatest undertakings of all, drawing on the genius of the Imperium's most accomplished military architects and engineers. If the Chapter is to be fleet-based, then even more work must be put into the construction of a "Chapter Barque," a mobile star fortress or unusually large battle barge to serve as the Chapter's mobile fortress-monastery and all of the related capital warships and escorts such a highly-mobile Chapter will require.

The already extant Space Marine Chapters may also have a role in this process, though to what degree can vary greatly from Founding to Founding. Many of the First Founding Chapters maintain close links with Chapters created using their own gene-seed stocks, and the Chapter Masters might have a hand in planning future Foundings using that genetic material. It is said that the Disciples of Caliban, a Dark Angels Successor Chapter, was created following the direct appeal of the Supreme Grand Master of the Dark Angels, an extremely rare request.

In the more than 10,000 standard years that have passed since the First Founding of the 20 original Space Marine Legions by the Emperor of Mankind, there have been at least 26 subsequent Foundings of new Chapters of the Adeptus Astartes; with the most recent, the Ultima Founding of the Primaris Space Marines, occurring in ca. 999.M41, just as the Great Rift was forming.

Even before a new Founding is announced, entire generations of Imperial servants may have toiled in preparation. Even once the process has been declared and is underway, it is likely to be at least a standard century before the new Chapters are ready to begin combat operations.

In times of dire need for the Imperium, faster development has been attempted, but this has often resulted in disaster. Gene-seed cultured in haste is wont to degrade or to mutate, and a great many other factors may lead the entire process astray. And there is no foe more dangerous to the Imperium of Man than a Space Marine who has been corrupted by Chaos or gone Renegade for another reason.

Not every Chapter can trace its genetic and cultural lineage to one of the primarchs. Over the millennia records have been lost, destroyed, tampered with or concealed. For some Chapters being ignorant of this part of their history is a source of immense frustration, and they take great pains to learn anything they can of their brotherhood's origins, waging entire wars for fragments of information.

Others care little. They believe that it is their task to defeat and kill the Emperor's foes, and that knowing or recovering lost parts of their history contributes little to the successful fulfilment of their purpose.

Rumours often abound around these Chapters regardless, as some demonstrate the traits of certain First Founding Chapters more than others, or even exhibit the characteristics of more than one equally.

These Unknown Founding Chapters cannot count on the brotherhood often found among Chapters descended from the same primarch. Their alliances are hard-won, and the mystery that surrounds them sees them deemed unworthy by some. Nonetheless, they are loyal Chapters of the Adeptus Astartes, and they fight furiously for the Imperium.

The creation of the original 20 Space Marine Legions by the Emperor of Mankind is known as the First Founding and it took place at the beginning of the Great Crusade in the late 30^th Millennium. It consisted of 20 Legions of Space Marines each made up of roughly about 50 companies divided into various other units in the ascending hierarchy of battle, including Chapters, Great Companies or some other organisation depending on the Legion's own unique naming conventions.

The Second Founding divided the remaining 9 Loyalist Space Marine Legions into units known as "Chapters" which were each about 1,000 Astartes strong after the events of the Horus Heresy in the early 31^st Millennium. The Second Founding was deemed necessary by the Primarch and Lord Commander of the Imperium Roboute Guilliman in the wake of Horus' betrayal in order to prevent any one person like Horus from ever again possessing the full power of an entire Astartes Legion and the extraordinary threat it presented to the existence of the Imperium.

One Chapter from each Loyalist Legion was permitted to retain the original colours, iconography, and name of their First Founding Legion, and these Astartes are known as the Chapters of the First Founding.

Reasons for New Foundings

The Imperium is a realm governed as much by superstition and paranoia as it is by the cyclopean bureaucracy of the Administratum. While many long-term policy decisions come about due to the work of generations of planners and strategists, just as many are the result of arcane predictions, ritual foreseeings and readings of the Emperor's Tarot.

Often, galaxy-wide strategic decisions are a bizarre combination of these two factors, interwoven over solar decades of debate and analysis until both become one and the same. In some quarters, this esoteric discipline is known as strategic prognostication.

In the case of the founding of a new Space Marine Chapter, strategic prognostication may warn of a threat approaching the Imperium from a given quarter; a threat so dire that only the establishment of a Space Marine Chapter in the region may defeat it. In many cases, the nature of the threat will be well known and linked to ongoing wars.

This was the case when twenty or so Chapters were assigned responsibility for guarding against Traitor Legion incursions through the Cadian Gate. In that case, the threat was well established, and readings of the Emperor's Tarot indicated it would greatly increase over the following centuries.

In other cases, the nature of the threat is not known at all and is only revealed much later when a previously unimagined enemy invades. Strategic prognostication may have been the reason the Scythes of the Emperor Chapter was created, its homeworld located close to the already well-defended Realm of Ultramar.

Sometimes, the Emperor's Tarot gives no indication at all with regards to the reason for a new Chapter's creation, providing no clues as to what it should guard against, what it should fight or where it should be based. The process merely indicates that the fates demand the new Chapter be created, and so, it is.

Counterthreat

Many Chapters have been created at the express order of the High Lords of Terra in order to counter a specific threat. Generally, the activities of a particular known foe have increased to such a level that one or more Chapters are created specifically to counter it.

No Space Marine Chapter ever focuses exclusively on one enemy, however, and even if the new force is initially created to counter a particular foe it will soon be carving its name in history against a myriad of enemies. Quite often a Chapter created with no specific remit develops a particular expertise in fighting a specific foe, and comes to regard doing so as a matter of honour.

The Crimson Fists are an example of this, with a great many of the Chapter's wars having been fought against the Ork empires that infest the border regions between Segmentum Tempestus and Ultima Segmentum.

Some crusading Chapters have claimed or been granted a homeworld in a region they have fought to conquer, and in so doing established a bulwark against the return of the enemy, be it secessionists, aliens or worse.

Standing Force

Some Chapters are created to operate in a specific region, though as ever their wars may take them the length and breadth of the Imperium. This is simply a case of the High Lords of Terra identifying a particular region whose defences are considered lacking, and where the stationing of a Space Marine Chapter would bolster the region's defences considerably.

Though consisting of only a thousand warriors, a Space Marine Chapter is able to project its power over a huge area, and intervene in wars for light years all around. The presence of a Chapter homeworld in a nearby cluster is often sufficient to deter invasion and insurrection in dozens of surrounding sectors, for the Space Marines can mobilise their rapid Strike Cruisers at a moment's notice and there are very few foes that cannot be suppressed, if attacked quickly and brutally enough, by a single Space Marine Strike Force.

Crusade

Many of the Imperium's wars are in fact mighty Imperial Crusades, raised from the armies of entire sectors to reclaim a lost part of the Imperium or to destroy once and for all a particular foe. Such Crusades often sweep up billions of warriors, several thousand of whom may be Space Marines.

Perhaps in the past, during a greater epoch of the Imperium, entire Chapters of the Adeptus Astartes were founded with such Crusades in mind. Perhaps future crusades will be so great that new foundings are ordered, and new legends of the Adeptus Astartes will be born.

New Chapters

New Chapters are only created by an Imperial edict of the High Lords of Terra, and, some whisper, by the sole will of the Emperor of Mankind. The task of actually assembling these Chapters always belongs to the Adeptus Mechanicus. The Adeptus Mechanicus store the gene-seed of all the Adeptus Astartes Chapters which they receive in the form of a tithe.

Using lobotomised human test-subjects (most of whom will later be converted into servitors), the Mechanicus produces new Progenoid Glands. Zygotes of the necessary Astartes gene-seed organs are grown from the gene-seed stores on Mars and implanted into the test-subjects and the zygotes then develop into Progenoids and are surgically removed.

A single test subject is used in this way to create two Progenoid Glands, which are then implanted into two more slaves, and so on. Ultimately, 1000 sets of the 19 necessary gene-seed organs to give birth to a new standard Astartes are created, taking over half a standard century of constant culturing.

A different method for the creation of the gene-seed implants of the Primaris Marines was used by Archmagos Dominus Belisarius Cawl to create the hundreds of thousands of new Astartes of the Ultima Founding. Many of these Primaris Astartes had been recruited after the end of the Horus Heresy, and had known in living memory the primarchs whose gene-seed they bore.

They were kept in stasis on Mars for over ten thousand standard years until the resurrection of Roboute Guilliman during the 13th Black Crusade. Only when he ordered Cawl to complete the process of creating the Primaris Marines in the wake of the Terran Crusade was the vast undertaking of the Ultima Founding finally initiated. It represented the largest number of new Space Marine Chapters created since the Second Founding.

Known Foundings

First Founding (Late 30^th Millennium)

The First Founding of the Space Marine Legions, also originally called the Legiones Astartes in High Gothic, occurred in the late 30^th Millennium after the end of the Age of Strife and during the Unification Wars that founded the Imperium of Man on Terra.

Twenty Space Marine Legions were created from the gene-seed of the 20 known primarchs engineered by the Emperor of Mankind from His own genetic code in His gene-laboratories in the Imperial Palace on Terra beneath the Himalazian (Himalayan) Mountains.

Two of those Legions and their primarchs, the II^nd and the XI^th, would fail to meet the Emperor's expectations and would be eliminated, with all records of their existence completely expunged from Imperial records.

At the dawn of the 31^st Millennium and towards the end of the Great Crusade, the Emperor's most favoured primarch, Horus Lupercal, became corrupted by the Ruinous Powers and plunged the galaxy into a new Age of Darkness as the Horus Heresy raged across the Imperium of Man.

Fully half the Space Marine Legions fell to Chaos, becoming the Traitor Legions, who were eventually defeated and driven into the hellish warp rift, known as the Eye of Terror.

Second Founding (ca. 021.M31)

The Second Founding of the Space Marines occurred seven standard years after the end of the Horus Heresy, in ca. 021.M31.

This Founding involved the division of the existing Loyalist Space Marine Legions into the far smaller, 1,000-man autonomous Chapters of the Space Marines as decreed by the new Codex Astartes, written by the Ultramarines' primarch, Roboute Guilliman.

The remaining nine First Founding Space Marine Legions still loyal to the Emperor were divided into smaller Successor Chapters -- one Chapter maintained their parent Legion's original name, badge and colours, while the remaining Chapters of their primarch's genetic lineage took on new names and heraldry.

Unstated Founding (ca. M31)

• A Founding which occurred sometime during the Imperial expansion of the Time of Rebirth.

3^rd Founding (M31)

The 3^rd Founding was initiated at the suggestion of Rogal Dorn, the primarch of the Imperial Fists and the Praetorian of Terra. After more than forty standard years of preparation, the High Lords of Terra approved over a hundred writs of succession to both First and Second Founding Chapters. The Ultramarines were granted nine writs of succession alone.

4^th Founding (After 546.M32)

This Founding occurred shortly after the climax of the catastrophic events of the War of the Beast -- the massive Ork WAAAGH! Warlord known only as The Beast -- which laid waste to much of the known galaxy and threatened to destroy Terra itself.

Following the successful eradication of the massive greenskin invasion force and the defeat of its Warlord, the Lord Commander of the Imperium Maximus Thane decreed that the Imperium would raise as many new Chapters as it had gene-seed in the great vaults of Terra to sustain.

All Chapters of the Adeptus Astartes were ordered to release a portion of their Veterans to provide the initial basis for this Founding, the greatest since the First Founding.

Gene-seed tithing would be doubled for the next standard century to replenish the vaults. When it was done, there would be hundreds of Chapters to ring the Imperium in adamantium and ceramite instead of dozens.

After enough gene-seed had been collected in the vaults on Terra, the High Lords of Terra authorised the 4th Founding of the Adeptus Astartes, sometime in the latter fifth century or early sixth century of M32, to help bring order to an Imperium rife with civil strife and insurrection, and to help restore Imperial law.

The 13^th Founding occurred sometime between the 35^th and 36^th Millennia and is one of the very rare Foundings of Space Marine Chapters that was not recorded in exact detail. Since the bygone days of the Horus Heresy, the Adeptus Terra has maintained a bank of original gene-seed from every single Chapter ever created, with one notable exception: the 13^th Founding, also known as the "Dark Founding." There are no reliable records that indicate how many Chapters were created during the Dark Founding or what became of them. There are only two acknowledged Chapters that were created during this mysterious Founding.

The Chapters created during this so-called 21^st 'Cursed' Founding have all suffered from terrible misfortune or some form of genetic corruption or rampant gene-seed mutation.

This is largely because it is believed that the Adeptus Mechanicus sought to "improve" the gene-seed used in the Founding of these Chapters without authorisation from the High Lords of Terra.

23^rd Founding (Late 37^th or Early 38^th Millennium)

The 23^rd Founding (also known as the "Sentinel Founding") may have been one of a series of linked Foundings around this tumultuous period in Imperial history.

It was intended to repair the power and reach of the Adeptus Astartes, which had suffered considerable losses in the preceding millennia.

The Celestial Lions may also have been raised as a part of the Sentinel Founding, but this would then place the Founding in the early 38^th Millennium.

Ultima Founding (ca. 999.M41)

The Ultima Founding of Space Marine Chapters has occurred in the wake of the fall of Cadia during Abaddon the Despoiler's 13^th Black Crusade. The scattered Space Marine Chapters of the galaxy have been bled dry over the millennia of ceaseless battle.

With the advent of gigantic Warp Storms that swallowed whole star systems, the formation of the Great Rift and constant attacks by the forces of Chaos, rampaging xenos and more, the Adeptus Astartes were stretched thinner than ever.

With many Chapter planets now actively under siege, some Chapters were confirmed as destroyed or lost, and even those faring relatively well suffered high casualties and were in desperate need of reinforcement.

With the resurrection of the Ultramarines Primarch Roboute Guilliman, the Avenging Son assumed command as Lord Commander of the Imperium over all of Mankind's military forces. He put into action his ultimate contingency plan, 100 Terran centuries in the making -- the Primaris Space Marines.

These new transhuman warriors are the next step in the evolution of the Emperor's angels of death. They have been genetically altered according to a design laid down by Archmagos Dominus Belisarius Cawl of the Adeptus Mechanicus.

Compared to their Firstborn brethren the Primaris Marines are bigger, stronger, faster and more genetically pure. The Primaris Space Marines of the Ultima Founding -- who have been added to existing Chapters as well as raised among entirely new Chapters of their own -- represent a timely and massive reinforcement for the Imperium's armies as Humanity's enemies close in for the kill.

These Unknown Founding Chapters cannot count on the brotherhood often found among Chapters descended from the same primarch. Their alliances are hard-won, and the mystery that surrounds them sees them deemed unworthy by some. Nonetheless, they are loyal Chapters of the Adeptus Astartes, and they fight furiously in defence of the Imperium.
