But when a con goes wrong and he needs a place to lay low for a while, he finds himself wearing the power armor of the augmented infantry.

Ataegina was an isolated world of medieval castles, varied cultures, and conquests, vibrant until the demons rose and spread relentless destruction. Swarms of lethal creatures with black husks, murderous claws, barbed tails, and dreaded “tooth-tongues” raged through the lowlands, killing 90 percent of the planet’s population. Terrified survivors fled to hidden mountain keeps where they eke out a meager existence. When a trio of young warriors discovers a new weapon, they see a chance to end this curse. To save humanity, they must fight.

Led by Zula Hendricks, the Jackals seek to rescue the few survivors from the depths of the planet, but have they arrived on time?
