In the harsh and unforgiving desert, entire villages vanish without a trace, swallowed by the merciless sands. Yasir al-Amin, the Headman of the Oasis of Zephyr, is determined to unravel the mystery of these eerie disappearances.
Yet superstitious beliefs of sand worms and demonic djinn have left Yasir's dervishes paralyzed, unwilling to venture into the deep desert. What he needs . . . are outsiders.
But the sands of the desert will not give up their secrets easily.
Meanwhile, deep in the recesses of a vast sinkhole lies a monstrous creature of unspeakable horror, a beast so foul and loathsome that it could only have been spawned from the darkest depths of the earth.
This adventure is designed for characters of 5th-6th level.
