It is the 11th day of the 285th year since the founding of the Third Imperium. Which translated into the Terran calendar is the 1st November 4802.
The Third Imperium is expanding to Spinward and is encountering the Vargr as they are expanding Rimward. The Imperial research station, in fact an underground bunker on the remote moon of Idmiston Up has gone dark. There have been no communications with them for the last 28 days.
The PCs are tasked with going to the station and finding out what happened.
Idmiston Up is a 5 day in-system trip away, and the PCs have access to a Pinnace to get them there if they need transport.
Imperial scientists were tasked with coming up with a solution to the “Vargr Problem” and the Idmiston Up research station were looking into ways of using Vargr physiology to provide a solution.
