Mothership - The Burning of Carbex

Carbex was once covered in lush forests, before the fire. Everything burned, except for some silverfish-like insects who fled underground. Millenia later, coal miners break into their refuge. 

About a week later, you are contacted by a nearby law enforcement agency. The Angelus Fabrica Station orbiting Carbex issued an automated distress signal after deploying every escape pod. 4 days of communication attempts without response met the persistent distress signal. The agency offers you a decent sum to determine the complete evacuation’s rationale and to rescue and assist, by any means necessary any remaining crew members. The Angelus Fabrica is a disaster, most of its residents having been killed or altered by the strange transformations these parasites affect in their hosts, The Creeping Perforation.
