Duel Monsters - The Shadow Realm

From the introduction: The Shadow Realm. A land forsaken by its creator. The Goddess Horakhty once ruled over this world, creating wondrous creatures like the 7-Colored Fish, the Silver Fang wolves, the Skull Red Birds and the variety of Dragons that served as the mighty rulers of the world. The world was her canvas, as she created legendary oceans and towering mountains. Her greatest decision in this world was to allow the wandering spirits from another world enter, to give her ideas.
