Malcolm Kane, mass murderer and former servant of the Gaunt Man, has discovered the location of the Core Earth Darkness Device. With its power at his command, he can join the ranks of the High Lords and rule a new realm, one patterned after the bloody Aztec Empire of long ago.

Core Earth's only hope is a group of Strom Knights on the trail of Kane. Challenged by menaces from the past and the present, tempted by the power of the Darkness Device, only they can prevent the destruction of Core Earth's reality.

From Central America to Mexico, the Knights pit their courage and strength against undead legions, ancient war gods, and finally the power of Kane and the Darkness Device in this thrilling adventure. Ahead of them lies their greatest victory- or a devastating defeat that will change the course of the Possibility Wars for all time.
