Treasure Hunt in the Heavens

Conquer the heroic spirits in the troubled times of the Three Kingdoms, and walk on the blue waves of the Caribbean; bravely fight against the undead natural disasters on the continent of Valoran, and fight bloody battles with the dragons on the Blue Star; discuss magic and arcana with Gandalf in the Lord of the Rings, and strategize in the Holy Grail War; cut off the heads of the Olympus gods under the World Tree, and the Celtic gods tremble behind them. The final competition began at the place where it all began, from a stubborn rock on the seashore. (Slow heat, new book for newcomers, don't comment if you don't like it)
