Argel Tal - History: Argel Tal was born in the village of Singh-Rukh on the world of Colchis, the homeworld of Primarch Lorgar Aurelian. Argel Tal's name meant "The Last Angel" in the Colchisian dialect of the southern steppe tribes, as he was the final child to be born in his family. Tal was inducted into the Word Bearers Legion of Space Marines by its First Chaplain Erebus, who at first had chosen him to become one of that Astartes Legion's Chaplains before he rejected that honour.Instead, Argel Tal eventually became the Captain of the 7th Assault Company of the Serrated Sun Chapter of the Word Bearers. While aboard the light cruiser Orfeo's Lament alongside the former Cadian priestess and Daemon Prince Ingethel the Ascended, Argel Tal was among the first Humans of the Imperium of Man to discover the Realm of Chaos that existed in the Immaterium within the Eye of Terror Warp rift while the Serrated Sun Chapter carried out the Pilgrimage of Lorgar.While in the Immaterium, Tal was possessed without his knowledge, like many of his fellow Astartes in the Serrated Sun Chapter, by a Daemon, in this case one called Raum. Unlike the later possession of Daemonhosts by the malevolent entities of the Empyrean, this possession was less a brutal subjugation of the host's physical body than a symbiotic fusion of both beings on a spiritual level, essentially transforming the host into one of the first Possessed Chaos Space Marines.Indeed, Lorgar would later point to Argel Tal and his fellow survivors of the journey into the Eye of Terror as examples of what Mankind could become if Horus succeeded in overthrowing the rule of the Emperor of Mankind and delivering the galaxy into the service of the Chaos Gods. Tal eventually returned to his Legion after a 7-solar-month-long subjective ordeal in the Eye of Terror that lasted only moments for those of the Legion waiting in realspace for the Serrated Sun's return.During questioning by Lorgar, Tal detailed what he had experienced in the Eye of Terror, providing useful insight later used as the foundation for the heretical Book of Lorgar outlining worship in the Chaos Gods. In honour of his achievements, Lorgar made Argel Tal the Captain of his Gal Vorbak (the "Blessed Sons" in Colchisian) an elite cadre of Astartes made up of the surviving members of the Serrated Sun Chapter who were the first to wear the crimson colour on their Power Armour that would eventually become the standard colour called "Traitor's Red" for the entire XVII Legion after their turn to Chaos during the Horus Heresy.Argel Tal led the Gal Vorbak on Isstvan V during the infamous Drop Site Massacre against the Raven Guard Legion and their Loyalist allies, the Salamanders and Iron Hands. Argel Tal was the only Word Bearer trusted by the Legio Custodes warriors who had been tasked with watching over Lorgar by the Emperor of Mankind after the Primarch's betrayal of the Imperial Truth on the world of Khur. This made his ultimate betrayal of them all the more poignant when he was responsible for their murder after they discovered that the Word Bearers had become Traitors to the Imperium at Istvaan V.Sometime during the first 40 Terran years of the Gal Vorbak's existence before the battle on Istvaan V, Argel Tal become known as the "Crimson Lord" amongst the Astartes of the XVII Legion and later across the Imperium. The group of over 100 Remembrancers sent to the Word Bearers before the Drop Site Massacre already knew Argel Tal by this title, indicating that he earned it well before the start of the Heresy.
