Rulk the Great Traitor is at large. For a thousand years he perfected the infernal machine, with the help of which he hoped to gain dominance over the world. But to control it, he needs the unique ability of Karana, who has the gift of sensitivity. Karana and her lover Lian find themselves in the disappearing Night Land. Only Rulk can open the gate and send them back to Santenar. But Karana is afraid that he will subjugate the young man. Iggur and Mendark, sworn enemies of Rulk, are trying to draw energy from the rock. They must seal the gate before Rulk takes his invention to Santenar. If they fail to do this, the world will be at the mercy of the caron. But if successful, Karana and Lian will be doomed to remain forever in the Night Land.
