This adventure takes place on the world of Mithril, a cold, low-population frontier world. The Travellers land at Mithril’s rudimentary starport, only to find their vessel disabled and the base strangely empty. As the Travellers explore, they discover there may be survivors of whatever happened at the port. A distant distress beacon is detected, but reaching it requires an overland trek. Having located the survivors, the Travellers discover their problems are only just beginning…

Mission to Mithril is in part homage to the Classic Traveller adventure, Mission on Mithril, and in part a sequel. Any group of Travellers will be suitable for this adventure, though outdoors skills such as Recon and Survival will be highly useful, as well the ability to drive an ATV and fight.
