Cobalus Interfector

The Cobalus Interfactor is a Black Shield within the elite Deathwatch chapter of Space Marines. He was recovered in 020.M42 in the Caligari Sector by Watch Fortress Surgegate. Since his recovery, he has earned titles during his single-minded hunt and execution of chaos-aligned orkoid tribes.

History
The Cobalus Interfector's past is nebulous at best; the mysterious warrior keeps it close to himself, and refuses to divulge it to anyone. It is not because of distrust of his comrades in the Deathwatch, but the simply does not feel it relevant to his mission now.

Recovery
In 020.M41, the Cobalus Interfector was discovered after the dissipation of one of the many warp surges that are common in the Caligari Sector. Adrift in the void within the Balthar system of the Tenebra sub-sector, the Cobalus Interfector was alone; his armor stained entirely in the blood of Orkoid species, in his right hand a combat knife stuck through the dead corpse of a gretchin that showed signs of chaos corruption. Surrounding the lone marine and his kill were countless other gretchin and ork corpses with the same type of wounds and chaos corruption as the one that was currently skewered. A surreal scene of corpses floating in the void with debris from some detonation evident around. Yet despite the evident carnage, the newly recovered Cobalus Interfector was still conscious, and was awaiting the rescue that came.

Initium Occitor
Since being recovered and inducted into the Deathwatch at the local Watch Fortress, the Cobalus Interfector dedicated all of his time and powers given to him by Inquisitor and fellow Astartes Valrius Cothar to hunt and kill the chaos-corrupted orkoids he has become proficient in killing. For, after his recovery, a handful of chaos-corrupted orkoid clans have been discovered infesting the sector.
