Corvus Corax
The Primarch of the Raven Guard. His most notable characteristic was that he some emo piece of shit that got owned then became a total pothead.Also spent alot of time making retarded emo poetry.
History
When the Emperor was doing his "awesome pwn the galaxy and other awesome shit" plan he created twenty fuck-hard dudes who would be his generals. But then Chaos was like "you'll never rule da galaxy. Mwa hahahahaha." And then they stole the babies and sent them to random planets in weird space pods. One had a dude whose name was Corax. He landed on a gay planet where everyone was a slave who were watched by some pretty mean guards which meant that whatever fuck-head ruled this bit of rock had an unlimited source of manpower. Well it was a typical grimdark day for those slaves. You know, "make weapons for the soldiers so they can oppress us" when they discovered some random white skinned child who became Corax, "The Deliverer" in their language, they kept him from their DICKtators who didn't really give a shit, training him in a lot of different skills so that one day he could go up to the DICKtator and fucking knock the shit out of him and become a leader. Taught to be a leader as well as a rebel, he began his job by bossing the workers into squads, making the best of the best into squad leaders. He then was like " let's build a huge stockpile of weapons, so that we can not be slaves!" Then everyone was like "YAY!" So then they hid shit by placing them in secret factories and whatnot.He then ordered a campaign of psychological warfare,by starting riots and strikes to get followers in the worker's rebellion and to stretch the garrison strength and morale to breaking point. Waiting for the best time, Corax's army did their thang, by capturing some security points.
When the DICKtators struck back, Corax was ready for them. He outmaneuvered, out gunned and out-everything,and ambushed their army with his bad-ass legion of union workers, destroying their supply lines and striking the DICKtator with random nukes and shit like that. Soon, the DICKtator's forces were blown to little bloody pieces of man flesh, their fuck-huge factories unable to make anything due to slaves not being around, and everyone was like "Yo da DICKtator is dead!". Celebrating their victory, the inhabitants of that shitty lil' bit of rock named their home Deliverance.
Rumours said that the Emprah appeared on Deliverance that day made to make Corax Primarch of the Raven Guard Legion. No-one gives a damn of what was said of their conversation but one condition of Corax's acceptance was that he could be in charge of bringing peace on random planets 'cause he didn't know that's what the Empy wanted. Soon the Adeptus Mechanicus stepped in and the world was rebuilt so that the Imperium could get some use out of it. Then some tower was made called the Ravenspire, which was the fortress of the Legion.
Great Crusade
When the Great Crusade was happening Corax's talents for planning and sabotage were really great and that was how the Raven Guard fought, fighting frequently under the orders of Horus, became renowned for an awesome can't be matched ability with spec-ops, sabotage, infiltration and lightning strikes and all that spy shit. But the pair never agreed, and after an argument, Corax was like "I can't deal with this shit" and Horus nearly killed him. Corax left Horus's command after flipping Horus the bird.(You get it? Cause ravens are birds! Yeah it's a shitty pun. Deal with it.)
Horus Heresy
Corax met Horus on Isstvan V. He gave Horus the finger. Again.
He was then seriously hurt and started crying like a pussy and then he escaped the jolly ol' fightan with a few loyal Space Marines. Corax was sent back to his legion's home world to rebuild his legion as soon as possible. The Primarch was desperate as the Imperium was about to be destroyed which was not good, not good at all. His Emperor needed warriors that Corax could not give. Searching for an answer among the library , Corax found the really old books of genetic research, one of which was titled "Genetic Modification for Dummies," which was basically the awesome skillage used to create the first enhanced warriors of the Emperor, those techniques Corax copied shamelessly to create Space Marines at a frightening rate. Despite the warnings he found amongst the old books, he started rebuilding his Legion faster than a pot smoking monkey. Then the Legion started fighting alone, isolated from the other Imperial Forces because every one thought that Corax was a depressive psychopath. Oh and the results of the cloning experiments were a bunch of really fucked up mutants lead to combat by their Battle Brothers.
At this time, Corax led his warriors as he had always done, with small squads striking like lightning on the enemy weak spots. he then finished building his legion. By that time Horus was dead.
After the heresy Corax he got so depressed that he decided to get super high and got himself lots of 'Geneseed,' and left his marines to fight alone like the faggy douches they were.
Then all the other primarchs and Imperials got pissed at him, so he went even more fucking emo and locked himself in a bigass tower to fap to furry porn and BAAAAW for a few years and then ran off like a frothing psychopath/pussy to the land of Abaddon. Nobody knows if he received the forgiveness he wanted but he wasn't seen again. His last recorded words were "never more" or some bit of faggy goth poetry like that.
