Mechanicus outpost vx11b

Mechanicus outpost vx11b was an isolated outpost on a large asteroid in the Volkar system.  A stygian raider ship bombarded the facility forcing a sudden evacuation
 It was later discovered that the magos biologis had not evacuated a number of containers holding mutagen used in bioengineering.  A astropathic message revealing this was determined to have been intercepted by Death guard forces.   Determined to ensure that the Death guard did not get control of the mutagen a small strike team was dispatched setting the stage for outpost vx11b to become a battlefield.
