The Sunken Shrine is a location in the original Final Fantasy situated undersea just off Onrac, and is accessible by a barrel found on Onrac's dock. The Water Crystal lies here. The Sunken Shrine is a more difficult dungeon to navigate than the other abodes of the previous Fiends of Element. Several floors have multiple staircases, some of which may lead to dead ends. One chain of staircases leads to a floor that is enemy-free and inhabited by mermaids whom the player must visit to proceed. The player can talk to them to learn of the Kraken's siege on their home, and many of their rooms contain treasure chests with valuable equipment.
