As he settles into rural life—planting crops and building relationships with the townspeople—Raguna discovers that the tranquil region harbors darker secrets in its caves and ancient ruins teeming with monsters. His emergence as both a skilled farmer and capable swordsman opens a path into exploration and combat, drawing him closer to understanding the otherworldly threats encroaching on Kardia and the circumstances of his own lost identity.
