In their relentless mission to expand the Zangal'an Empire, elite conquerors known as Slayers are sent across the cosmos to claim new worlds. One of the most feared among them—Zaatis, known on Earth as Elijah—arrived more than thirty years ago. But instead of unleashing destruction, he found love with a woman named Zara, built a family, and tasted a life he was never meant to have.

A tragedy shatters that peace.

Now, Elijah intends to finish the mission he abandoned and burn Earth to ash. As the threat of a planetary Harvest looms—an event capable of wiping out humanity—Zara faces an impossible choice. Stand beside the man she loves as he fulfills his destiny… or rise against him to save her people from extinction.
