Kulth - Tale of House Severan: Almost two thousand standard years ago in the mid-39th Millennium, the Calixis Sector was hewn from the xenos-haunted depths of the unexplored region of the Segmentum Obscurus once known as the Calyx Expanse by the blood, sweat, and tears of the countless thousands of Imperial martyrs who prosecuted the Angevin Crusade. The endeavour was a mighty one and only made possible by the combined efforts of numerous arms of the Imperium’s military machine. Hundreds of regiments of the Imperial Guard fought across worlds boiling with xenos corruption, millions-strong advances spearheaded by the elite Adeptus Astartes. The skies were darkened by the massed fighter wings of the Imperial Navy while warships as numerous as the stars themselves burned across the void. The war machinesof the Adeptus Titanicus bestrode the battlefields like armoured gods while the private armies of the most ambitious of Rogue Trader houses fought in the hope of one day ruling those worlds wrested from the dead grip of nameless xenos fiends. It was one of these militant Rogue Trader princes that led some of the boldest thrusts into the region, so deep into the Calyx Expanse that he all but broke through into the Wilderness Zones beyond. That man was Duke Severus I, the bearer of a Warrant of Trade granted to his line by the High Lords of Terra themselves. Yet, his name is all but unknown in the Calixis Sector, while those of lesser men are celebrated across a hundred systems and more.The deeds of Severus I and his companions were so heroic that they should be known and celebrated across not just the Calixis Sector, but the entire Imperium. It was Duke Severus who unlocked the Markayn Marches Sub-sector by plasma-boiling the hideous xenos spawning seas of Cantus Extremis, breaking a deadlock that had stalled the advance of three million Imperial troops. It was Severus who discovered and charted the Warp route between Dreah and Iocanthos, when the fleet-masters of the Imperial Navy were convinced the path spinward must surely lie between the Prol System and Fedrid. It is even said that a mighty Warp beast assailed the Duke’s flagship as he closed on Ganf Magna, the creature’s vast tentacles wrapping about the vessel so that when Severus ordered an emergency translation into realspace, the thing was dragged through too. Weakened by exposure to the laws of the material realm, the beast was eventually defeated. But before it faded from existence, Duke Severus himself hacked out a single, crystalline eye several metres in diameter and worth the ransom of a High Lord of Terra.As great as his numerous victories were, it was the duke’s deeds in forging the Periphery Sub-sector that earned him true glory, for a short time at least. Of the Heretic and xenos fiends the duke’s fleet confronted as it ranged ahead of the main Angevin Crusade advance between Sepheris Secundus and Sinophia, the few extant archives are all but silent -- the Inquisition and other bodies having determined such truths unfit for public dissemination. In most cases, only the names of otherwise unknown battles remain. The Scouring of Cyclopea Nine; the Kulth Landings; the Retreat from Avitohol, closely followed by the Avitohol Reprisals; the War of Ash, in which a thousand xenos vessels are said to have been sent plummeting through the upper atmosphere of Sisk, the survivors ruthlessly hunted down by vengeful human natives. It was at the Second Battle of Kulth that the duke’s greatest moment came, his armies counterattacked by a millions-strong horde of slavering xenos monstrosities. Little is known beyond a faded entry in a crumbling tome, locked in the stasis vaults beneath the Lucid Palace on Scintilla, stating that the duke rallied his armies in person, even as the xenos horde closed in on all quarters and all seemed lost. The unknown scribe goes on to claim that Duke Severus faced a xenos being of such monstrous nature that his greatest champions were struck down by madness, but that he was not, delivering the killing blow with his own hand and turning the battle and the entire campaign in an instant. The xenos hordes were put to rout and with them, those human-held worlds that had resisted the Imperium’s advance capitulated. The region that would one day become known as the Periphery Sub-sector was opened up and a Warp route discovered that connected the region to the distant Scarus Sector, ensuring its fortunes as shipping hubs sprung up along its length.Why then, are the deeds of Severus I unknown to the peoples of the Calixis Sector? The answer is simple and lies in that most basic of human flaws -- the sin of hubris. Duke Severus I had been promised much by the terms of his Warrant of Trade, but in truth the High Lords of Terra had never expected him to survive the terrors that lurked in the Calyx Expanse. Before being granted his title, the duke was a senior courtier of the Senatorum Imperialis on Terra and his political trajectory was carrying him towards a seat on that highest of councils. His numerous rivals found this greatly disconcerting, for they believed Severus to have murdered numerous of his compatriots during his rise to power. These rivals engineered the granting of the Warrant of Trade, forcing Severus to embark on a Crusade they hoped would end his ambitions, his career, and his life. Severus was fully aware of the High Lords’ intentions and when he succeeded in carving the Periphery from the darkness of the Calyx Expanse, he interpreted the terms of his warrant to justify him claiming it as his personal realm, exempt from the laws and demands placed on the rest of the Imperium. In essence, Severus installed himself as the exclusive ruler of his own private empire within the boundaries of the Imperium, which in his eyes he had earned by the spilling of his blood and that of countless thousands of his followers.In other circumstances, Severus I might have been allowed to realise his ambition, for the frontiers of the Imperium are often expanded by men with similar dreams of avarice and power, only to be absorbed into the greater mass of sectors generations later. This might have been the case with Severus, were it not for the simultaneous rise of a man who regarded him as a vainglorious and self-interested robber baron interested only in expanding his own domains off of the blood, sweat, and tears of millions of the God-Emperor’s faithful servants. This man was Lord General Militant Drusus, the man who had succeeded Lord General Militant Golgenna Angevin as the leader of the Angevin Crusade that conquered the Calyx Expanse. While Severus had been conquering the Periphery for his own ends, Drusus had been leading the armies of the Imperial Guard in a series of victories every bit as glorious as those earned by the duke. While Severus set about consolidating his power after the Second Battle of Kulth, Drusus fought on, claiming untold worlds for the God-Emperor of Mankind. Following his apparent death at the hands of the agents of rivals (which may, or may not have included Severus) and subsequent resurrection, Drusus was beatified by the Ecclesiarchy as a Living Saint and is celebrated to this day as the patron Imperial saint of the Calixis Sector.Duke Severus was soon eclipsed by Saint Drusus and his plans to establish his own realm were cast to ashes. With every one of the leading lights of the Angevin Crusade openly worshipping Drusus as a paragon of the Emperor's justice, none would support Severus in his own ambitions. For a time, Severus turned his back upon his former peers amongst the Angevin Crusade, eventually only speaking with the famous Rogue Trader Sibylline Haarlock. What passed between the two remains unrecorded and some believe that Haarlock denounced Severus upon learning of his intentions to establish his own private realm. By the time Drusus was pronounced the first Lord Sector of Calixis, Severus was a broken man. He died in 417.M39, less than a month before Drusus himself passed away. To the last, he was a resentful, bitter man, turned by the cruelty of fate from a noble merchant-admiral to a paranoid recluse.
