Marines Errant - Chapter History: A star-spanning Chapter of noble renown, the Marines Errant's own histories record them as one of the Chapters of the 23rd Founding of the Adeptus Astartes, which many sources place in the latter part of the 37th Millennium.The 23rd Founding is generally believed by Imperial scholars to have been one of a series of linked Foundings around this period designed to repair the power and reach of the Imperium's Space Marine forces which had suffered considerable losses in the preceding millennia.According to the Requiem Malesent of Saint Kybra, no fewer than fifty-seven Space Marine Chapters had been destroyed outright, turned Renegade or declared as lost during this troubled period, which had seen calamities such as the horrors of the Age of Apostasy, the disastrous Cursed Founding, the attacks of the forces of Chaos and a rampage of Orks almost unchecked along the Imperium's frontiers.The Marines Errant, along with several other Chapters, were from the outset conceived as Chapters that would spend their existence on continuous crusade and were to be created from the most stable gene-seed stocks available to the Adeptus Mechanicus.Articles laid down and enshrined from this time, preserved in the Marines Errant's archives on Vilamus, entreat the Chapter to "... forever quest and give battle, knowing no home but the grace of the Emperor's mercy, finding purpose only in the destruction of the enemies of Mankind."Since their inception, the Marines Errant have dutifully pursued this course, ceaselessly travelling between war zones across the distant, far-flung stars of the Imperium, and are one of the few Chapters that are known to have crusaded far beyond the edge of Mankind's domains and returned.Further details of this Chapter's origins can be found in the Mythos Angelica Mortis, the great work concerning the Space Marines of this age, which lists five such new-founded Crusade Chapters and their blood-progenitors, with the Marines Errant recorded as having the Eagle Warriors Chapter as their immediate forebears.The Eagle Warriors' gene-seed was drawn from the Ultramarines' lineage, although why the Eagle Warriors in particular were singled out for the honour of a "named" Founding being drawn from their ranks at this time remains lost to posterity.The Marines Errant have forged for themselves a glorious series of battle honours by undertaking one Imperial Crusade after another in the name of the Emperor, some of which still burn in the pages of the Chapter's history, whilst others have been long forgotten.The Chapter was also notably involved in the many wars that made up the Age of Redemption in which the Adeptus Ministorum's Imperial Creed was reimposed on a wayward Imperium cleansed in the blood of the apostate. However, the Marines Errant are most famous for their later Crusades into the outer darkness of the galaxy.From the very beginning, the intent of the Marines Errant was that they would engage in endless crusades, cleansing the cosmos of any taint that might offend the Emperor or interfere with humanity's domination of the stars. Because of this, the Chapter designed its organisational scheme around the notion of independent stability for each of its companies.During its existence, the Marines Errant Chapter has never established a formal fortress-monastery nor has it designated a specific homeworld. Instead, the Chapter has known little rest as its members travel to constantly expand the boundaries of the Imperium.While this limits some of the fellowship between Space Marines assigned to different companies, the additional tactical flexibility has served them well in fulfilling their designated role.The Age of Redemption, which lasted through most of the 37th Millennium, was a period in which the Imperial Cult first assumed its current levels of authority within the Imperium. In the centuries leading up to this time, the Ecclesiarchy had grown corrupt. Eventually, this corruption was identified and overthrown.With the change in leadership, faith in the God-Emperor became an increasingly vital element in Imperial life. Many who embraced their faith with tremendous zeal felt that penance was necessary for the terrible crimes that had taken place in the previous centuries. For some, the only imaginable service that could be appropriate was the idea of embarking upon an Imperial Crusade against the alien and heretical forces that contaminated the galaxy.Through its initial centuries of organisation, the Marines Errant Chapter was a product of this era. Its Battle-Brothers participated in countless crusades, which ranged in scale from targeting only a few worlds within a star system to enormous wars that extended across entire sub-sectors.As it participated in these countless efforts to make recompense for the Imperium's past sins, the Chapter continually proved its value as guards and warrior-ambassadors to those places where Mankind had not yet ventured.During the years 390.M38 through 433.M38, the Marines Errant Chapter sealed a covenant with the Rogue Trader House of Ecale. The reason for this agreement remains a secret tightly held by both parties. However, it remains clear that the ties formed at that time remain in place. To this day, there are always Battle-Brothers of the Marines Errant Chapter operating on detached service among the vessels of House Ecale.It may be that whatever task they agreed to at that time has not yet been completed. However, it might also be that the Chapter owes the bloodline some debt that cannot be repaid within a single lifetime.Service among House Ecale is regarded as an honour by members of the Chapter. Those who serve continue to wear the Rogue Trader's badge on their armour long after they return to the Chapter. Many also bear highly ornate Power Armour or armaments that they have received as gifts from the house.In the early 40th Millennium, five companies of the Marines Errant Chapter formed the core military elements for the Kadyron Voyage into the Hazeroth Abyss of the Calixis Sector. This expedition, led by Inquisitor Lord Kadyron, is regarded as an unmitigated disaster.A lone battle barge survived the expedition. Through the course of the journey, the Chapter lost the majority of its Land Raiders, Dreadnoughts, and numerous Warp-capable transports, as well as countless Battle-Brothers.Were it not for its systematic storage of gene-seed, the Chapter might not have been able to rebuild from the losses. Even with an increase in the number of Initiates accepted, the Marines Errant Chapter is likely to suffer from the losses to irreplaceable wargear for millennia to come.The Chapter recently participated in the Corinth Crusade against the forces of WAAAGH! Skargor within the Corinth System. Under the leadership of Marneus Calgar of the Ultramarines, the crusade decimated the Ork Empire, and effectively eliminated the xenos threat to the region for several solar decades.During the course of the war, the 4th, 6th and 9th Companies earned tremendous recognition for liberating the Ultramarines' 3rd Company when it was effectively pinned down by a vastly superior Ork fleet.Battle-Brothers of the Marines Errant engaged in boarding actions against dozens of Skargor's Terror Ships, providing the Ultramarines the relief they needed to swing the momentum of the battle in the favour of the Emperor's cause. Marneus Calgar went so far as to graciously award the Chapter one of the Ultramarines' sacred Relic Blades as a sign of their camaraderie.
