Decimus Androdinus Felix - History: Decimus Androdinus Felix was one of the first men chosen to become a Primaris Space Marine. Originally hailing from the Shrine World of Laphis in the Macragge System in Ultramar, he was taken as an Ultramarines aspirant soon after the end of the Horus Heresy in the early 31st Millennium.But instead of becoming an Ultramarines neophyte, he was sent to Mars along with hundreds of thousands of other aspirants on the orders of Roboute Guilliman to become part of Archmagos Dominus Belisarius Cawl's project to create a new type of improved Space Marine.Felix spent thousands of standard years in and out of cryogenically-induced suspended animation as he and his fellow Primaris Space Marine candidates were experimented upon as Cawl sought to perfect the Primaris variant of Astartes gene-seed. They were also awoken at various intervals to undergo relentless sessions of hypno-indoctrination.It seemed the cycle of experimentation and psychological conditioning would never end until Roboute Guilliman was unexpectedly resurrected during the Ultramar Campaign of the 13th Black Crusade in 999.M41 by Cawl and his allies among the Aeldari Ynnari faction.As Roboute Guilliman once more assumed the position of lord commander of the Imperium, he ordered Cawl to finally unleash the Primaris Space Marines, for the Imperium of Man stood on the brink of disaster as the forces of Chaos and the xenos threatened Humanity at every turn. Guilliman ordered the start of the great Indomitus Crusade into the regions of the Imperium most threatened by the onset of the Noctis Aeterna.Felix was among the nine Space Marine Legion-sized formations of Primaris Space Marines known as the Unnumbered Sons, and eventually rose in the course of the Crusade to become a lieutenant of one of its companies.His performance drew the attention of Guilliman himself, who ultimately selected Felix to leave the ranks of the Greyshields and become his equerry. At the same time, Felix was surprised when the primarch declared that he was also now a captain of the Ultramarines Chapter, a position that Guilliman had never given to the other Astartes who had previously served as his equerries.He was also recognized as the eleventh captain of the Chapter, which broke the strictures laid out in Guilliman's own Codex Astartes-mandated order of battle for a Space Marine Chapter.Felix often was troubled by these promotions, believing himself unworthy of the responsibility which they portended. But Felix performed well in his role as equerry, and when the Indomitus Crusade's first phase ended at the Battle of Rauxos some twelve standard years into the 42nd Millennium, he was among the forces that travelled with Guilliman to aid the defence of his Realm of Ultramar from the offensive of the servants of Nurgle led by the Death Guard Traitor Legion and Guilliman's traitorous brother, the Daemon Primarch Mortarion.This assault, known as the Plague Wars, had been ongoing almost since the birth of the Great Rift, and the forces of the Ultramarines had found themselves pushed onto the defensive by the time of Guilliman's return to his realm.Immediately after his arrival, the primarch convened a meeting with the leaders of the Ultramarines and all of his accompanying forces to hash out a strategy for the defence of the realm. Guilliman made clear that he not only intended to defeat the forces of the Plague God, but also to restructure Ultramar itself.Guilliman explained that he had made a mistake when in the wake of the Horus Heresy he had consented to drastically shrink the size of Ultramar from five hundred worlds down to a bare handful.It was time to restore the Five Hundred Worlds, and to guarantee that this initiative would be successful, Guilliman recreated the ancient ranks of Tetrarch and announced that his equerry would be among their number.Decimus Felix immediately protested that he was certainly not worthy of such a position, but Guilliman claimed that Felix's actions during the Indomitus Crusade had proven over and over that he had all of the personal qualities that being a Tetrarch of Ultramar would demand. After all, the lord commander continued, that was why Felix had been made his equerry, to prepare and test him to take on this vital role.Felix bowed then to his primarch's wishes. He was assigned to rule the world of Vespastor and charged with enlarging Ultramar's eastern expanse using all the considerable tools at his disposal, reclaiming those worlds from the Noctis Aeterna and restoring them to the Emperor's light.After accepting his new rank, Felix commanded Vespator from the palace known as the Regia Tetrarchia and was referred to by the title "Lord of Vespator and the Eastern Marches." He was protected at all times by his Honour Guard, known as the Chosen of Vespator, each of whom was a Space Marine who had been chosen from one of the Shield Chapters of Ultramar.When Felix left Vespator he did so aboard his personal flagship, the strike cruiser Lord of Vespator. Despite the vast power and responsibilities laid upon his shoulders, Felix sought to emulate the example of his patron Roboute Guilliman in all things.This included taking to his duties with sober-minded dedication. After he became a Tetrarch, Felix began to visit each of the sectors under his command, an activity he greatly enjoyed since it provided an excuse to get away from the constant demands of politics. It was during one such visit to the world of Sotha that Felix and a small group of his Chosen of Vespator joined with Archmagos Dominus Belisarius Cawl to explore the xenos ruins present on that planet.During the Plague Wars in Ultramar, Felix served as one of the primary Imperial commanders but left his own designated warzone to meet with Roboute Guilliman after his return to Ultramar aboard the primarch's flagship, the Macragge's Honour.Felix expressed his disagreement with the primarch's decision to interview a captured Daemonhost in an attempt to better understand the objectives of the Nurglite invaders. Guilliman chose to disregard his Tetrarch's advice, but expressed his appreciation for Felix's willingess to openly disagree with his decisions.When the Imperial forces launched their final assault upon the Death Guard's positions on Iax, Felix worked alongside the Aurora Chapter Codicier Donas Maxim and the Craftworld Aeldari Farseer Illiyanne Natasé of Ulthwe, the Asuryani's secret liaison with Guilliman, to defeat the Heretic Astartes and their Daemon allies.Felix watched in horror as Mortarion slew Guilliman with the use of the supernatural pathogen known as the Godblight, but was forced to withdraw with his forces as the unstoppable Chaos disease began to spread across the world uncontained.After the power of the Emperor manifested directly in the Warp and resurrected Guilliman for a second time while scouring away the Godblight, Felix met once more with the primarch aboard Macragge's Honour.Guilliman explained that he intended to take his portion of the Indomitus Crusade into the Imperium Nihilus next and he wished his Tetrarch farewell and good luck with the ongoing reconstruction and expansion of Ultramar.
