From publisher blurb:
Although considered a desolate wasteland by the settled races, the Great Northern Desert is the cradle of many civilizations. Although now considered separate lands, the spheres of influence of the gatormen, ophidae, scorpionmen, not to mention fallen Hekata, rose, clashed, and fell here. Even the jinn lorded over the northern desert once. Yet for each of these known ancient cultures a dozen more are now forgotten, the crumbling ruins of their former cities, temples, and tombs are all that remains of their former power. Much adventure, wealth, and danger await those who would disturb the haunted structures.
