Corvus Corax

"'WANTING TO GO OUTSIDE WAS A TERRIBLE IDEA. THE BOX DOES NOT JUDGE. IT JUST HATES.'"Corvus Corax is the Primarch of the Raven Guard, and nineteenth son of the Emperor. He can be considered the protagonist of the Spin off Bro Trip, having the most character development off the two Brothers.

Official Canon
Corvus Corax was found on a remote mining colony that had been enslaved by the nearby planet. When he was found by the miners, immediately they realized he was special, and kept him hidden from the overseers. Over the years, he was being trained and prepared to lead the rebellion to liberate his world, and became an expert on ambush tactics and asymmetric warfare. When he finally emerged and freed his people, the planet was renamed Deliverance. It was at this time that the Emperor discovered him.

Horus Heresy
Corax was among the loyalists who were sent after Horus when his treason had been discovered. However, he, Vulkan, and Ferrus Manus were betrayed by their fellow primarchs, who also declared for Horus, and had their legions decimated in the Drop Site Massacre.

Desperate to rebuild his legion, Corax used the Emperor's cloning labs where he first created the Space Marine legions using a modified gene-seed in an effort to make new marines more quickly. Corax's efforts were foiled when Alpharius secretly added daemon blood to the gene-seed, turning his men into barely functional mutants. Those that could fight were sent as kamikaze units to seek absolution in death. Those that survived were doomed to degrade until they became insane, and so were personally given the Emperor's Peace by his own hand.

Post-Heresy
Deeply remorseful of his actions, Corax left for the Eye of Terror to fight the Traitors. He was never seen again.

TTS Canon
Vulkan intercepted Corax and stuffed him into the Engine of Woes, one of the artifacts of Vulkan, which has been found and placed back on Nocturne by the Ultramarines. Therein he had been writing gothic poetry constantly, and when he heard rumors that his brothers were returning to the Imperium, he attempted to get out, only to find that he was now stuck.

Corax finally escaped when Magnus hurled the Engine of Woes at Vulkan. Corax swore to kill the traitor, but Magnus escaped. Vulkan embraced Corax and swore to finish hugging Magnus; Corax decided to follow him so that he could kill Magnus to keep that from happening. Corvus rejected the possibility that Magnus had simply returned to the Emperor's good graces and firmly believed that he was plotting something. Regardless of his intentions, Corvus was adamant about returning to Terra as quickly as possible.

On their first stop they recruited the Catachan Jungle Fighters; while proficient warriors in their own right, Corvus was annoyed by their lack of proper equipment and their inhospitable home planet. When a Catachan Barking Toad somehow landed on his head without him noticing (which was attracted by his smell since he hadn't bathed in millennia), Corvus resolved to make sure no one would be killed by it except him. He intended to fly into the air so that no one else would be killed by the toad's explosion, only to be saved by Sly Marbo at the last second, who kicked the toad off his head and brought him back to safety.

When Corvus and his ship crashed on Atilla due to Clancy 's betrayal, Corax wanted the traitor executed, but was forced to keep him alive to find out more about his plans and to preven the exterminatus of Atilla. Corax was livid and confused when Clancy managed to escape, though.

On Jopall, as Vulkan was dying of the Life-Eater Virus (from the exterminatus missile, which Corax claimed he kept "as a momento"), Corax rushed him to the surface and pleaded with the planetary governor to get them medical support. In a rush he signed a contract that caused both his and Vulkan's fleets to be impounded, their armor stolen, and forced to pay off a massive debt. Corax, stripped of all his gear, was inducted into the Jopall Indentured Squadrons, where he was mistaken for an Ogryn. When he pissed off the local comissar, the comissar tried to execute Corax, and failed repeatedly due to Corax's superior Primarch biology. While Corax was being guarded, he learned of how badly the Jopallians were being msitreated, and was able to convince them to start a rebellion against the planetary governor. While they succeeded, Vulkan passed away. However, Vulkan later resurrected himself and disappeared in a flash; Corax also learned that Clancy was the one behind their impounding, and swore to find both his missing brother and the traitor.

Personality
Corvus Corax’ melancholic attitude is taken to the extreme, as evidenced by his colorful use of depressing poetry. Even when he’s just monologuing, he chooses to use very descriptive and grim vocabulary as though he were some latter day Edgar Allen Poe. That being said, he’s also fairly pragmatic, pointing out the flaws in the Jungle Fighters’ equipment, and he’s not above fits of anger, mainly due to frustration with his mildly insane brother Vulkan. Even so, he cares deeply for Vulkan and his sons, as he was willing to sacrifice himself to protect everyone else from the Catachan barking toads. He’s also gracious to upstanding servants of the Emperor, having newfound appreciation for the Jungle Fighters after having been saved by Sly Marbo.

Corvus deeply resents oppressive and corrupt systems, and when the opportunity presents itself, is eager to tear them down and start rebellions, as seen on Jopall. Also, while he does hold himself in higher regard than most humans, this is mostly due to his cynical attitude and nature as a Primarch, he is in actuality, quite capable of empathising with and engaging with normals.
