Post-ROTK AU. This crossover has been done before, but not like this. Yami and Yugi lose a duel against Yami-Marik, who tries to send them both to the Shadow Realm. Instead, they find themselves in Mordor, where the card games dont matter anymore. Yugi learns of an ancient evil that threatens Middle-earth, and the role he is to play in the fight to decide the fate of Middle-earth.
