Returning from battles against serpentfolk in the underworld, the heroes must raise an army among the war-torn jungle ruins of Saventh-Yhi to annihilate the growing evils below. Yet raising such a force tests not just their diplomatic skills, but subjects them to brutal tests of courage and strength. With a savage army united, a path to the serpentfolk stronghold beneath the city must be opened, requiring the activation of an ancient device that drops seven of the city's massive towers to impale the accursed ruins below. As the warriors of the jungles do battle with legions of snakemen, the heroes make their way to the temple of the snake god Ydersius to face the serpentfolk's mad high priest and disrupt a ritual threatening to return the ancient evil god to terrible life.
