Red Angel - History: The Red Angel was created during the opening days of the Horus Heresy by possessing the body of Brother Meros, an Apothecary Minorius (a junior medicae) who served in the Blood Angels Legion's 9th Company under the command of Captain Furio during the Great Crusade and Horus Heresy. Initially, Meros was a simple line-Astartes of solid, if unremarkable service. But later on, during the opening days of the Heresy, his fate would become inextricably intertwined with that of his Legion and his Primarch Sanguinius during the Signus Campaign.It is said that Horus hated and feared Sanguinius more than any of his brothers and wove many strategies to ensnare or slay him, though all failed. In an effort to weaken and divide the Loyalist forces, the Warmaster charged the Blood Angels Legion with the arduous task of cleansing the Signus Cluster -- a triple star system of the Segmentum Ultima near to the galactic centre.Sanguinius' Legion was ordered to cleanse the 7 worlds and 15 moons of the Signus Cluster of xenos invaders and release the humans thereon from their xenos-overlords. Unaware of the Warmaster's perfidy, Sanguinius willingly obeyed his brother Primarch and immediately set out for this volatile region of space. Unbeknownst to the Blood Angels, they were blindly walking into a deadly trap, for the Signus Cluster had fallen prey to agents of the Ruinous Powers and become a veritable Realm of Chaos -- a system of hellish Daemon Worlds under the rule of a Greater Daemon of Slaanesh known as Kyriss the Perverse.Rising to the challenge of the vile Greater Daemon, the Blood Angels Legion attacked the daemon host of Kyriss, launching a series of attacks across the seat of the daemon's power, the world of Signus Prime. The Primarch spearheaded the Blood Angels' assault on the Greater Daemon's seat of power, known as the Cathedral of the Mark, to confront and destroy Kyriss and reclaim the planet in the name of the Emperor.When the Primarch was struck down by Ka'bandha, a Greater Daemon of Khorne, the Blood Angels were consumed by a black rage that drove them into a berserker's fury as they charged into the daemonic horde. In their madness they smashed the horde of daemons asunder. A small cadre of former Librarians used their combined psychic abilities to heal their Primarch and wake him from his dark torpor, bringing him back from the edge of the abyss.The Angel finally arrived to confront both Kyriss and Ka'bandha. The Bloodthirster and Sanguinius fought once more, but ultimately, the Primarch prevailed and cast the Greater Daemon back into the Warp. The Blood Angels then discovered the source of the rage that had infected their entire Legion.The Dark Apostle Erebus had created a fell device, a psychic construct known as the Ragefire, which contained and was powered by the half-dead body of Captain Tagas, the former Captain of the Blood Angels' 111th Company, who had been presumed killed in action on the world of One-Forty-Twenty, the planet called Murder by all the Space Marines who had fought there several standard years earlier.Through the use of the dark sorceries of Chaos, the Word Bearers had created a conduit of undiluted rage that consumed nearly the entirety of the Blood Angels Legion. Driven to uncontrollable rage over their fallen Primarch, the Forces of Chaos hoped that the Blood Angels would lose control of their noble aspect, and willingly give themselves over to the Scarlet Path and the worship of the Blood God Khorne.
