Prepare to confront the incarnation of evil. It is 1820 and the world is on the brink.

A fearless cohort of soldier-monks, led by Lieutenant William Saxon, has been dispatched to Egypt on the most important mission in history. For thousands of years a great secret has been kept: a stockpile of appalling malevolence, which, if let loose, will plunge the world into eternal damnation. This is the Hoard of Mhorrer. The soldiers must find and destroy the Hoard before the daemonic agents of the evil Count Ordrane of Draak locate it.

In a heart-stopping race against time, ranging from Papal Rome to the desolate heart of Egypt’s Sinai peninsula, the soldiers must battle murderous militiamen and pitiless daemons, and finally, terrifyingly, the bloodthirsty Guardians of the Horde.

If William and his men succeed, the clandestine war between Heaven and Hell will at last begin to favour the forces of light. But if they fail, and the agents of Hell claim the Hoard, then they will unleash an army of invincible daemons, and humankind – what is left of it – will come to know the true meaning of evil.
