Lukius is the leader of the Priest-Soldiers that are chasing after Caius Qualls. He is the right-hand man of the Pope, and his goal is to hunt and execute all the Leymon. He has been to almost every spot in Areulla. His mask is a symbol of his position, and he is not allowed to show his bare face. Working for the church as a Priest Soldier, it is his job to round up Leymon with his partner Rommy and to take them to the capital city of Janna. However, he does not like what he is doing and in truth wants everybody to live in a fair world. Unfortunately, he believes that genocide is the best way to go about it.
When the main characters defeat Lukius in the desert, his mask comes off and his face is revealed for the first time. To everyone's amazement he looks almost exactly the same as Caius. This is because the two of them are actually brothers, separated at birth at sent to live with different parents. Caius went to live with his mother, Lady Melissa, and Lukius went to live with his father, the Pope. After he reveals himself to the party, he calls Caius "Big Brother" instead of Caius. Despite subjecting hundreds of Leymon to horrible deaths at the hands of the Pope, Lukius actually wants to create a world where everybody can live peacefully. However, he has to keep capturing them until his father has enough souls to cast Life Presiputh, a powerful magic that will liberate his friend Rommy.
Caius and the party encounter Lukius in the Pope's cathedral as they try to reach the Pope himself. Refusing to let them past him, Lukius fights the party one last time. Lukius loses and supposedly dies from his wounds. However, when the party returns after defeating the Pope, his body is gone. When the party encounters Rommy for the last time on Mt. Arye, Lukius appears, injured but still alive. He helps the party by turning Rommy into her true form, a Spot.
