The Sea of No Return is a location from The Legend of Zelda: Oracle of Ages. It is located in the far eastern section of Labrynna in the past. It can only be accessed by a special, underwater passage that leads through a cave and to the entrance of the Sea of No Return. The cave can be found on the peninsula on Crescent Island, the same entrance to the Moonlit Grotto in the Present. A mysterious force in this strange place prevents Link from using the Harp of Ages to travel through time and access it from its present form, the Yoll Graveyard. The maze preceding the final dungeon is filled with many red and blue Darknuts and Lynels. The Sea of No Return contains the eighth and final normal dungeon of the game, Ancient Tomb.
