From publisher blurb:
Nestled in a twisting ravine amid the Luminous Desert’s endless windblown dunes, Rifthammer is home to a desert-dwelling tribe of dwarves. Hidden in the cool shadows of their cliff-side home, these reclusive folk offer peaceful seclusion for those seeking refuge from the desert's relentless heat, or simply the troubles of the wider world. However, not all is as idyllic as Rifthammer’s dwarven masters pretend, and a festering ruin of otherworldly creatures in the darkest recesses of the rift threatens all who reside above.
Rifthammer can serve as a base of operations for adventurers looking to explore the surrounding Luminous Desert, or as a jumping-off point for subterranean adventures in the ruins of an ancient city that long ago collapsed into the rift's lightless depths.
