Purge of Koros

The Purge of Koros was an Imperial castigation campaign fought by the Blood Serpents Space Marine Chapter against the Forces of Chaos in the Koros System, located adjacent to their Chapter home system of Astoran. To aid the beleaguered Imperial system, the Chapter command despatched the Chapter's 4th Company, led by their High Chaplain to eradicate the Chaos-worshipping cultists.

History
During 582.M36 a Chaos Cult worshiping Khorne was discovered in the Koros System, near Astoran so Salsain took an army comprised out of the 4th Company, with the aid of High Chaplain Kuthru Zarlan to eliminate the new found Chaos Cult.

When Salsain arrived on Koros the cult immediately started summoning in a hoard of Blood Letters, and other Khorne Daemons. The Blood Serpents realized that they needed to act fast to shut down the portal quickly, before the Daemons overran the world. So Salsain led his forces in a straight up assault toward the portal, in a more reckless move then he normally would.

Salsain saw a massive Bloodthirster swooping in so he took off and engaged it in one on one combat, after a while he managed to bring down the Daemon, however most of the company was already dead, he only saw a couple of his marines left, with no sign of Captain Kolan, or High Chaplain Kuthru Zarlan, so Salsain flew at the portal where most of the cult was, he then landed and started cutting down the cultists, then tearing into the portal.

After the portal was down the Daemons link weakened, Salsain carved his way through the Daemons, and due to the lack of blood being spilled the Daemons slowly poured back into the warp. However, Khorne recognized that Salsain was an excellent warrior, so he grabbed Salsain, and took him into the warp.
