Dark Pegasus colony

The conquest of the Pegasus asteroid mining complex led to the creation of the Dark Pegasus colony.  A place where the Dark Mechanicus exploited the natural resources to feed the Stygian Empire's war machine while using prisoners captured in the Stygian wars as a slave labor force.  The Dark Pegasus colony garnered a black reputation of having an 80% mortality rate amongst prsoners in the first 2 months.
