Iskandar Khayon - Birth of the Black Legion: During the years after Horus' defeat at Terra, Khayon spent most of his time as a warrior for hire. His favoured compensation for his services was either Battle-Automata to be used for defence of his starship, or valuable lore. For instance, Khayon spent six Terran years fighting for the Night Lords warband led by the warrior Dhar'leth Rul, in exchange for a map of parts of the Webway.During those years, Khayon encountered and befriended a Drukhari Scourge by the name of Nefertari, binding her soul to her flesh after she suffered mortal injuries at the hands of the Greater Daemon Zarakynel. Nefertari herself remained oblivious to this fact, however, never realising her soul was now permanently bound to her dead body.Khayon answered the call of his old friend Falkus Kibre of the Justaerin, who was requesting aid in a search for the lost Sons of Horus flagship the Vengeful Spirit. After the fall of the XVI Legion's stronghold on the world of Maeleum within the Eye of Terror, the Lupercalios, and the theft of Horus' remains by the Emperor's Children, finding the lost flagship seemed the last hope of redeeming the Sons of Horus Legion's honour for its remaining warriors.Understanding the possible threat that cloning a Primarch as the Emperor's Children intended would pose, Khayon agreed to help Falkus in retrieving the flagship and striking against the Emperor's Children base of Canticle City, where the remains had likely been taken after the theft. They were joined in this effort by Captain Lheorvine Ukris of the World Eaters.The meeting was interrupted by the arrival of Emperor's Children vessels, whose Astartes demanded Falkus' surrender. A small-scale skirmish ensued, which saw both the World Eaters and Sons of Horus warships seemingly destroyed. As a result, Lheorvine and some of his surviving World Eaters escaped with Khayon aboard the Tlaloc, alongside the captured Emperor's Children swordmaster Telemachon Lyras.Khayon and his warband later reunited with Falkus and his men, who had survived the previous encounter, and had been daemonically Possessed. They later managed to find the Vengeful Spirit, along with its captain, Ezekyle Abaddon. The warband that would soon become the very first faction of the Black Legion struck at Canticle City, successfully destroying most of it.Afterwards, the warriors boarded the Emperor's Children's vessel Pulchritudinous, where they discovered that Fabius Bile had succeeded in cloning Horus. The fight with the resurrected Primarch saw both Khayon's familiar Gyre and his bloodward Nefertari slain.The Horus clone also used its great Power Mace Worldbreaker to shatter Khayon's great axe Saern. The fight only ended when Abaddon finally managed to kill the clone, ironically delivering the killing blow with the former Imperial Warmaster's own Talon of Horus.Khayon would later pledge his allegiance to Abaddon's Black Legion, becoming the third of its elite Ezekarion. Soon after, the newly formed Black Legion ended the Legion Wars in the Eye of Terror. One by one the Daemon Primarchs bowed before Abaddon as the new Warmaster of Chaos -- with Magnus the Red having to be brought to his knees by the psychic might of Khayon.
