Trama
Dartz shows Yami and Kaiba the history of Atlantis, how the Orichalcos drove them into insanity, and how he lost his wife. In an attempt to save his people, Dartz made a contract with the Great Leviathan to use the Orichalcos to purge mankind, in order to restore "paradise." However, he was stopped by the three Legendary Dragons and former King Ironheart. Back in the duel, Dartz plays the second layer of the Seal of Orichalcos, Orichalcos Dueteros, and he uses his Mirror Knight Calling to summon his four Mirror Knights, each containing the souls of Yugi, Joey, Pegasus and Mai. However, if the Knights are destroyed, their souls may be lost forever.
