Theron Vael has spent eight years searching for his missing sister, becoming a mercenary and a powerful Spiritual Swordsman along the way. He knows she is alive, but the spirits who know her whereabouts refuse to guide him. Ilyra Vael, now a talented young mage, has spent those same eight years searching for the mysterious path forced upon her by an unknown voice. She believes her brother died on the night their village was destroyed. Their lives change when Ilyra hears the name of a legendary mercenary: Theron Vael, the Spiritual Swordsman. For the first time, she has reason to believe her brother may still be alive. But as Theron draws closer to the truth and Ilyra follows a path she does not understand, forces beyond their knowledge begin to move.
