The Executioners were nearly hunted to extinction at the hands of Keith T. Maxwell should Admiral Smith hadn't restrained him. Smith couldn't order their execution (ironic), so he arrested them and sent them to the Damarque I prison in the Augmenta system. However, they later escaped under the Terran Security's nose.
After escaping the Augmenta system, the Executioners proceeded to set up pirate outposts throughout the Nivelian sector and are currently subduing the Midorian faction in its grip of fear.
The Executioners quickly become the main adversaries of MACH after the kidnapping of Thomas Boyle.
