The second episode is a little more relaxed than the first, and it would be beneficial to have GDW's Double Adventure 2: Mission on Mithril. (In fact it's just a minor variant of that adventure.)

So much for the 'Fire', now comes the 'Ice'. Mithril is a cold world and the lifeboat has crash-landed several days walk from the local starport (such as it is). There are enough emergency food rations for everyone for 30 days, water (in the form of snow) is in abundance, but protective clothing against the cold is in short supply. There should be enough vacc suits (with insulation and built in heaters) for the player characters. They will have to trek to the starport and find rescue for the NPCs. But remember, the Sword Worlds military camp is near the starport, also.

For sound effects use a blustery wind rather than an arctic wind (there's a good example on the BBC's "Essential Weather Sound Effects" CD), but remember its not windy every day.
