"Curze and his Raven Guard wait...?"
Where Are They Now
Raven Guard
Corvus Corax never liked the Imperium.
The Imperial aristocracy reminded him of the tech-lords he had overthrown, and he described the warlords as "slaver filth". He deliberately murdered parts of his own Legion and replaced them with recruits from worlds he liberated.
The Ravenlord (he hated the nickname) regarded the Emperor as a blind fool so focused on the future that he ignored the present. Corax argued with the Emperor whenever they met, and he openly refused to conquer worlds for the "Greater Good of Mankind". He was hated by the Imperial aristocracy, the mortal officer corps, and many of his "brothers".
The Emperor found him immensely frustrating, yet he also admired Corax. His unbending determination to do the right thing regardless of the cost was very different from the Emperor's attitude, but he could respect Corax's devotion to human welfare. While many of his Primarchs fell prey to xenophobia, Corax held no hatred towards aliens. His Raven Guard were often selected for missions that required cooperation with alien allies, and they were widely beloved by the general population.
Corax refused to conquer worlds for the Imperium, so he spent the Great Crusade murdering tyrants. If some of those tyrants were Imperial, the net result was still beneficial for the Imperium, and Corax did not kill without cause. Given the vast number of truly horrible people, he was not targeting "mild" despots. When Corax painted a throne room with the blood of a particularly horrible governor, the Emperor didn't lose sleep over it.
Corax was not charming or personable. He had a deeply flawed, homicidal vision for the galaxy, and he was downright eager to solve problems with murder. Only Angron liked him. They fought together on many occasions, force and savagery matched with stealth and cunning, and they got along.
The Raven Guard suffered greatly during the Heresy, as Corax found himself matched against a genius that eclipsed his own. Horus was simply
better than the Ravenlord, and Corax became desperate for some way to level the playing field. In defiance of the Emperor's command, he sought the power of the Warp, embracing his full psychic potential as a Primarch.
When the Siege ended, there was an
energetic discussion about his decision. Lion El'Johnson wanted him dead, and he had the means to do it. Rogal Dorn and Leman Russ sided with the Lion, while Vulkan was willing to fight with Corax. Guilliman solved the problem in a simple, efficient fashion; a divorce.
Corax and anyone who wanted to go with him would depart in pursuit of the Traitor Legions. He would not officially secede from the Imperium. He would be assigned to hunt the traitors permanently, and he would swear a great vow not to return to Terra until the last traitor was dead. On the happy day that the last traitor
was dead, they would honor him greatly and he would still not return to Terra.
Corvus Corax agreed without hesitation. He had his Legion and his freedom, and he was planning on hunting the traitors anyway. The Raven Guard departed Terra, and most of Corax's followers (he never called them sons) followed him along the Path of Ascension.
They hunt the Night Lords in the Sea of Souls. They fight the Sons of Horus within the Eye of Terror, though they have the worst of it unless Corax himself joins the fight. The Raven Guard wage war unending against the Four and their followers, and they have been known to make...visits to the Imperium. It was Corax who slew Lord Commander Huron, bringing an end to his reborn empire.
Corax is
officially a Loyal Son, and the Ecclesiarchy continues to honor him. They just...don't mention any of the details.
The High Lords do not make Chapters with Corax's geneseed. After the defection of the Dusk Raptors and the Execution of the Carcahedrons, they have decided to avoid the Ravenlord's personal attention.
