The Vault of Darom Madar begins just after Sand Raiders, the short adventure provided in the Dark Sun Campaign Setting, ends. This adventure consists of three parts. By the end of the third act, the characters should have earned enough experience to reach 3rd level.
The adventure begins in Altaruk. After successfully retrieving the valuable cargo for Rhotan Vor, head of the Wavir tradepost in Altaruk, the characters are given the opportunity to search for the lost treasure of House Madar. The scant clues of the treasure’s location point to the Canyon of Guthay, a massive rift on the edge of the Great Alluvial Sand Wastes. More clues to the treasure’s whereabouts and information about the canyon can be found at Silver Spring but must be pried from the tight-lipped elves who guard that place. The trek to Silver Springs takes the characters across the Tablelands and pits them against the desert’s many dangers, including a band of mysterious assassins far more determined than simple desert raiders.
The second part of the adventure sends the characters into the Canyon of Guthay armed with information from the elves or only their own bravery. The Canyon of Guthay is a dark and forlorn place riddled with shallow, monster-infested caverns which hold many dangers for the characters. One of Guthay’s caverns holds the lost vault of Darom Madar, a place that is half treasure vault and half mausoleum. Here the characters must battle what remains of House Madar itself–undead horrors animated by centuries-old hatred–defeat a number of ghoulish traps, and finally win their way into the treasure vault.
The last part of the adventure challenges the treasure-laden characters to make the arduous trip across the Alluvial Sand Wastes to the great city of Tyr. During the journey, the characters are beset by monstrous horrors native to the Athasian wilds and another group of mysterious assassins who are eventually revealed to be operatives of House Tsalaxa, House Madar’s ancient enemy.
