Lost in the Mountain

Module introduction:

You were hired as escorts for a small cloth caravan that was travelling from Ogburg to Womtham. It was suppose to be a simple job through the Raker Mountains Pass until a flash blizzard hit.

Will you find safety or danger? There's only one way to know for sure....
