A band of cruel slavers transports their cargo across the blue-sands desert. They are savage and merciless. Before reaching their destination, the band is overtaken by a Dark Sky storm. Their cargo, Pau the fangling monk, Torment the dark one psion, Naut the scarred beast-man warrior, and Samiel the human bard are chained together and given clubs and knives by a slaver hoping to use them as muscle to escape the terrors in the storm.
Most of the slaves survive by fighting their way out of the storm and fleeing to a nearby cave to take shelter. Samiel and Torment are killed by the skeletal creatures that lurk in the storm. All of the slavers perish in the howling wind.
In the following day, the former slaves salvage what they can from the wrecked caravan, including a [mysterious gold coin that Pau feels a connection with, and depart in search of shelter. The rag-tag party soon finds an oasis and overcomes a sand folk ambush before sheltering there.
