The Hiberverse has been incubating a hidden evil, and the post-human Hibernarii have been inadvertently feeding it. Obsessed with the quest for immortality, the advanced human race known as Hibernarii have become plagued by a subversive strain of ancestral human clones that threaten to unravel their fractured empire and decadent lifestyle.

In a desperate attempt to restore balance, the Hibernarii create an enslaved race of assassins. Equipped with fission reactor hearts, inexhaustible killing capabilities, and a supposedly foolproof kill switch, the Templar are unleashed. After 300 years of constant slaughter, Templar Ranger 878 emerges as the epitome of the program–ruthless yet creative. But when Ranger loses a fateful battle on the obscure hibernaculated culture of Sizlack Prime, his world descends into chaos. Forced to partner with smugglers, Ranger must reconcile his violent past with his emerging future to save the Hiberverse.
