Defend the deep! A cry for help from the sun's interior leads the characters to dive in again. Forces loyal to an efreet from the Plane of Fire have conquered the deep-sun settlement of a peaceful alien species and threaten to destroy their way of life before it can be understood. The heroes must infiltrate the occupied city, make first contact with allies within, and defeat their fiery oppressors. As a strike team, the heroes must take out high-value targets and restore the proper order. Soon, they learn that this efreet attack is merely a beachhead for an invasion that could threaten the sun and the Pact Worlds!
