The Feeding

The Feeding is the name of the xenocidal purgation campaign conducted by the Omni Legion Space Marine Chapter to eradicate the Tyranids from the Imperial ice world of Roisigma of their foul presence.

History
Upon the ice world of Roisigma, the workers within the mines were horrified to discover something that needed the immediate attention of the Omni Legion. Within hours the 2nd Formation arrived at the request of the Adeptus Mechanicus that managed to system, they were filled in on a xenos threat discovered frozen in the ice mines - Tyranids.

Captain Vilhelm with his Executioners and a squad of Veterans all took to the world's surface to randevu with the Skitarii forces that had managed to secure the sector. Leading the assault themselves deep underground the Astartes easily dispatched the hundreds of Xenos that struggled to fight back in the black frozen caverns. Vilhelm and his elite forces note they had encountered similar creatures in the past during their service to the Deathwatch. These creatures were far less humanoid and more insectoid than what they had known but the resemblance was uncanny.

Vilhelm reached the deepest depths of the mine they had entered and entered an ancient Terran ship that the miners had been working on uncovering. Within they encountered Tyrant Guards. Vilhelm and the Executioners themselves fought against them while the Veterans protected them from swarming Tyranid Gaunts with the roaring fire of their storm bolters. One of Vilhelm's Executioners was slain by the sudden appearance of the Hive Tyrant. Enraged by this he charged the monster and clashed his powerful lightning claws with its own, one of its whip-like appendages wrapped around his leg and tried to knock him down but it was cut clean off by the reinforcements of his Executioners. It would not take long for the Veterans to turn their attention to the Tyrant, Skitarii had begun to flood the ship with the intention of wiping out the remaining Xenos that dared to dirty the walls of this ancient relic of mankind's history. The ship was large and they could only do so much before they were purely on the defensive, working to secure an escape for the Astartes.

The Hive Tyrant was no match for the combined efforts of nearly a dozen Terminators, three Honour Guards and the Captain of the 2nd Formation. It was blown apart and cut to pieces by the Astartes. As the Xeno fell the remaining Tyranids fled into the dark depths of the ship. Vilhelm ordered his Veterans to continue working with the Skitarii to exterminate the remaining Xenos.
