Short: Return and Codex

Hyperion - Koprulu Sector

Arriving to the place were they first found the Imperium's battlecruiser all those years ago Jim ordered his men to organize the fleet and then ordered his men to prepare for a speech he had cooked up. Soon all the work was done and all 6000 space marines eagerly waited for their commander to make his speech.

"Brothers and Sisters. We have returned home. I am sure that y'all have some odd feeling returning here after 5000 years. I have too. We returned here to fullfil a promise. A promise that we all made for what happened on Tarsonis. We promised to kill Arcturus Mengsk and secure a future for our people in this cruel sector. Our task will not be an easy one we all know that we face Zerg and Dominion both but we will still fight on regardless. If we stand together like we have for 5000 years there ain't nothing that can stop us. We will keep fighting for somethings are just worth fighting for. We know our first target and we are coming for him."

Jim took a deep breath yelling out louder than ever, "DEATH TO THE FALSE EMPEROR!"

and just like that all the Space marines replied, "DEATH TO THE FALSE EMPEROR!" This Psionically charged shout traveled through space with every Psychic feeling its raw collective power.

Char

Within the primary hive cluster the self proclaimed queen-bitch-of-the-universe felt the raw collective psionic power aimed at the Emperor of Dominion. The power of this collective terrified her especially because she could feel beneath that hate a different one a hate towards her manifested.

The whole sector felt it. A new power had emerged bent on killing Arcturus Mengsk and anyone else who would threaten the lives of those who wish to live in peace in the Koprulu Sector. And within the void a primordial force was disturbed by this new powerful presence knowing that it's plans had to be put into motion quickly.

Legends of the Raiders Chapter

Champion LeFleur: Former member of the SCV corp later a member of the Raiders 26th company. During the First Black crusade she rose to become a champion of the chapter by destroying a force of Daemons and Heretics that aimed to flank the Salamanders who were trying to protect civilians with the imperial guard. She had been stranded alone after an ambush destoyed her squad. Knowing that the reinforcements wouldn't arrive in time to intercept the flaking force she attacked against this Chaos force with a bolt pistol and a thunderhammer. When the reinforcements arrived they found out that the entire flanking force had been decimated and LeFleur laid on the ground exhausted and bleeding. It was this act that made her chapter's champion and she has worn that title with certainty ever since.

Michel Koiter the Venerable one: A First great war veteran Koiter has been with Raynor since the zerg invasion of Mar Sara and has been with him ever since. During the great scouring he was injured badly while covering his Commander and Chief Sorcerer while they planted a bomb that would destroy the necron tombs infesting one of the planets of their soon to be home sector. After that he was placed in a dreadnought and continued to serve the Chapter after this without dying for 5000 years. Now a Venerable Dreadnought he is respected by many Chapters even though Raynor mourns to see one of his friends entombed within that mechanical frame.

Reclusiarch McMurty: McMurty was already a chaplain before he became a space marine and continued as one in the chapters service. During the Great Scouring he was holding a position with one company of space marines against an ork WAAAAGH! The company held their position against the Orks for a year without faltering. It was later stated that McMurty was the one who inspired the company to hold as long as they had, it was this act that earned him the promotion to Reclusiarch.

Relations with other organisations and chapters

Blood ravens

For 5000 years the Raiders have held the secret of the blood ravens origins with them and have been helping the Blood Ravens in searching the knowledge lost on Prospero and bringing it back to them. A deep friendship still exists between the two chapters.

The Salamanders

Both chapters share a principle of protecting the people of the imperium so the two chapter respect each others readiness to protect normal human beings during the most desperate times and as such the two chapters usually find themselves to be the ones protecting the refugees during battles against the enemies of man. Vulkan and Raynor before the disappearance of the first had become close friends for both of them value self-sacrifice and brotherhood and this can also be seen when the 2 chapters interact with each other.

Space wolves

A distrust exists between the two chapters. One has to remember that the Raiders are all psykers like the thousand sons once were so it is easy to imagine where the distrust stems from. Thankfully no open hostilities have been reported during meetings.
