Your band of adventurers were caught by the ELDER DRAGON Nares of Corundum trying to rectify a situation of profound economic inefficiency, to wit, the existence of the same dragon's vast unused hoard of precious metals, and were thus rather unfairly presented with a choice of either being burned alive or accepting a MAGICAL GEAS to perform a quest for him. You can still hear the words of the greedy old lizard ringing in your ears - literally, in fact, as that's part of the geas and seems to happen randomly at the most inconvenient times:

This quest has taken you into the farthest reaches of the FROZEN NORTH, through perilous Yakyakistan and the hostile wilderness beyond. Finally, you have arrived in the outskirts of the REINDEER KINGDOMS. It has been a long and been a long and difficult journey, and your supplies are running low.
