Synopsis

Deep within the earth, an ancient evil has awakened. According to legend, three dragons shall re-emerge from the earth to wreak havoc upon the land. Preying upon the weak-willed, the dragon spirits grow stronger as they devour the innocent souls of their chosen hosts. Only the power of a long-dormant warrior-god can fulfill the ancient prophesy and defeat the growing evil. But will his chosen host be convinced to fight?
