Restless before bed, young Noctis asks his father, King Regis, to tell a fairy tale full of fantasy and adventure instead of just another generic bedtime story. Regis begins with a peaceful day being disrupted when monsters raid the royal capital, Insomnia. Young Regis, joined by Weskham, starts his adventure from the royal capital. Eventually they are joined by friends Cid and Clarus, where they travel to the plains of Duscae only to discover a mysterious cave where their enemy resides
