The Dragon's Curse

The world ended three thousand years ago. The surface is empty and dead, and mankind only survived by carving their new cities and towns in great sinkholes called Krads. In one of these Krads, a man named Tarn guards the town against the threats of the world beneath them. On one mission gone wrong, an ancient evil is released from its prison. Now Tarn and his companions, an elven druid named Malriel and Shar, the dark elf thief, must face a being so powerful and so malicious that the dragons themselves call him a curse.
