Throngs of undead trample the earth both night and day as Norrath's sun withers. With each passing hour, the growing numbers of creatures of the night rising from crypts and graves seem part of a grand design to overwhelm the lands. Trouble also lurks deep beneath the Buried Sea off the coast of Odus in a city named Katta Castrum, which has remained undiscovered for millennia. It is a city built to sustain the beloved leader of the Combine Empire who was poisoned. Generations of Combine Loyalists have tried to cure and awaken him while they house threatened populations of Kedge, Shissar, and Sphinx. But in recent times, the artifact that powers and protects their city has weakened. Without it, the city will be crushed under the pressure of the sea. Only the most intrepid Norrathians have the power to save them.
