Sinbad is born to the cynical ex-soldier Badr and his kind-hearted wife Esra in the tiny, poor Tison Village of the Parthevia Empire. His birth sends a brilliant wave through the rukh, announcing a singularity to those at the peak of magical might: the "Child of Destiny" has arrived. Despite his country's economic insecurity and the aftereffects of war, Sinbad has a happy life—until a stranger arrives and shatters his serene environment, and tragedy soon befalls him. Years later, enigmatic structures known as "dungeons" have been built all across the earth. These dungeons captivated the imagination of adventurers and armies alike, rumored to possess immense power and wealth, however none have returned to this day.
