Amid the turbulent times of the Achaemenid Dynasty, the Sorcerer Gaumata has set his sights on the highest jewel—the throne of the King of Kings. He plans to murder King Cambyses with his sorcery. Then Gaumata plans to take advantage of a complex scheme to seize the throne. Chaos and brutality grip the land as Gaumata abuses his power, but in the back of his mind a terror of his own lurks. He has crossed powerful witches and sorcerers who are now determined to bring him to his knees. The sorceress Spenta and her powerful mage brother Mihr are caught in Gaumata's trap, but they have allies in the two witches, Indrayani and Apuyani. They have finally discovered the key to his sorcery, and they plan to use it against him to save the kingdom.

Prince Darius, the real heir to the throne, is in danger when Gaumata understands that he has seen through his disguise. Will he be the next to face his worst nightmares in the world of horror only Gaumata, the fiendish sorcerer, can construct?
