The Wind Shrine is a shrine built to house the Wind Mirror in Final Fantasy IX, located on the Forgotten Continent in a valley filled with high winds. The party splits into four teams of two to tackle all four shrines simultaneously.
Steiner and Vivi are chosen to go to the Wind Shrine, where they meet Tiamat, the Guardian of Wind. After they defeat the guardians of Terra, Steiner and Vivi release the Wind Seal, thus allowing access to the world of Terra. The surrounding skies of the shrine are in a constant state of hurricane force winds.
Behind the scenes
Data hacking shows that there are many gaps in the numerical sequence of battle formations and monster IDs, showing that many battle formations and monsters were deleted prior to the final version. In addition to many more, three missing monster IDs appear around the "Earth Guardian", making one suspect that in the original version the player was to fight all four of the guardians instead of only one (in the final game, the other three are defeated via cut-scenes, including Wind Guardian/Tiamat). Design artwork for these other three guardians is known, as well as for deleted locations, which would probably have been where they were fought.
