Twilight's somber grace echoed softly through the grief-stricken Valley of Tsura. Not long after the loving burial of the beautiful Empress Zaiya, the valley was struck down in disbelief once more by the brutal slaying of her benevolent father-in-law, the High Emperor. A sharpened blade covered with fresh blood and an empty vial of poison coldly lingered beside his lifeless corpse. After the disappearance of the High Emperor's eldest son, who was also the husband of Empress Zaiya and father of their precious newborn Naora, the dire matter fell to the High Emperor's other sons Emperors Arel and Kozai to guide and protect their young niece. But with the power of the grave constantly calling out to them, the Emperors must fight to unveil the secret evil that threatens not only to claim the life of little Naora, but also complete domination over the Valley of Tsura.
