is sweeping through the palaces and temples of lower AEgypt, and unless the Pharaoh's most valued Magister, Setne Inhetep, can trace this plague of destruction to its source, the Triple Kingdom may be plunged into a magical darkness from which there is no escape.

There, Setne discovers an incredible plot to irrevocably split the kingdoms of AEgypt. But he can only watch helplessly as one by one the key plotters are destroyed by an unknown magical force. Trying to keep one step ahead of death's agent, Setne frantically seeks to root out the mastermind behind the scheme. But between him and the answer stands a dark god who may prove even more powerful than his own god Thoth....
