Ayo, an orphan from the town of Yak, was adopted by Grandpa Abel and carries the mysterious sword “Dawn” wherever he goes. The town mayor's extortion and a covert orc invasion shatter the peaceful life he once knew. Guided by Hope, a retired warrior, Ayo awakens his gift for light and forms the Dawn Squad with his companion Kayal. From driving off bandits and rescuing villagers in Blackstone Cave to defending Silvermoon City against an army of a hundred thousand orcs, they protect the weak with healing light and barriers.
But Lak of the Order of Light Knights steals their achievements, while the empire's Right Chancellor secretly conspires with the orcs, plunging the squad into crisis. At last, to uncover the secret of the Dawn Sword and fight the darkness lurking beneath the surface, Ayo and his companions set out for the Holy City. Thus begins a legend that will determine the peace of the continent.
