An upheaval in the Underworld accidentally awakens its ruler, who has slept for a thousand years. The chaos has claimed countless lives, so to replenish the Underworld's population, its ruler secretly heads to the Dema Continent, hoping to spark a war across the land and kill more powerful people to fill vacancies in the Underworld's administration. Unexpectedly, he lands in the dreaded Desert of Death. To get out of the desert, he first has to heal the helpless young man before him. They say the Desert of Death lies at the center of the Dema Continent. You can enter, but never leave; no one who has gone into the desert has ever come back alive. Deep within it stands a Lost Temple, filled with more gold and silver than anyone could spend in ten lifetimes, endless magic scrolls, and countless high-tier staffs and weapons.
