He is the 106th king of the Royal Capital Gairadite.
Not much of his personality was known before meeting Ahid, but afterward, Lycius became a devout follower of the Almighty Radiance. He truly believed he was bringing salvation to his people by feeding them to dragons, and he was willing to force his "salvation" onto others by letting a horde of dragons consume all of Azesion. He was deluded in believing that he was the chosen one to lead Azesion.
At some point, Cardinal Ahid Alovo Agartz approached Lycius and converted him to the religion of the Almighty Radiance. Tired of seeing his family hating and fighting each other for succession rights, Lycius "saved" them by feeding them to a white variant dragon. He believed that by offering their bodies to dragons, the messengers of the god, they would be closer to salvation and be reborn. Ahid also gave him the mission to kill Hero Kanon and obtain Evansmana, and only then will the Almighty One grant him eternal life and return him to this land as the true king of Azesion.
He then controlled the Royal Dragon using the power of the Guardian of Emotions. But Lysius was killed after Lay and Avos cooperated by using the power of love on him.
