Symmetry City

is a location in.

Overview
OoA: is situated in the northeastern mountains of Labrynna. The most prominent feature of the city is its symmetric design, creating a perfect mirror image over the y-axis. Each inhabitant of the city has their own twin. In the city lies the entrance to Skull Dungeon, home to the fourth OoA:. In the past, it featured a Middle House, which served as the town hall, where the Tuni Nut, OoA:'s sacred symbol that held the OoA: in balance, was located. Nowadays, in the place where the Middle House once stood, grows a OoA:, where Link can gather his first Gale Seeds. The tree also provides easy warp access to the city, which can otherwise only be reached by a bridge spanning the Nuun Highlands.

In search of the fourth Essence of Time, Link travels to the Nuun Highlands where a bridge crosses over to the Talus Peaks where the city is found. However, the bridge will not be built upon Link's arrival. At the request of Mutoh, the head carpenter, Link gathers up all the workers on break, with the help of his animal companion (either Ricky, Moosh, or Dimitri, depending on certain choices Link has made on his adventures). The workers will then build the bridge, allowing Link to enter the city.

When Link arrives in Symmetry City for the first time, he finds the city in ruins, infested with Podoboo Towers. Link then travels to the past to OoA: to find the cause of the problem, at which point he notices the volcano inside the OoA: erupting, wreaking havoc upon it. He then learns that the Tuni Nut, the OoA:'s sacred symbol, has broken. This causes instability in the OoA:, thus erupting the volcano. To restore balance to the OoA:, Link must bring the Tuni Nut to Patch atop Restoration Wall to have it fixed. Once the nut is fixed and placed on its pedestal in the Middle House, peace will return to the OoA:. The volcano becomes inactive, and the present-day Symmetry City will no longer be in ruins. In the present, the raging volcano is replaced by a waterfall, parted in the middle by the entrance to Skull Dungeon.

Trivia

 * Inhabitants of Symmetry Village claim to hear music flowing down from the mountains surrounding the OoA:. In reality, the music comes from Tokkey, who is researching a tune for the Harp of Ages inside a cave on Talus Peaks.
 * Also, there are two people who live on opposite sides of the city in the present who are not identical twins. One claims he is too small, the other, too big.
 * There are two BGMs for Symmetry City depending on its current state. Its BGM prior to the Tuni Nut being fixed is the music used shortly after Nayru/Din are abducted by the respective main antagonist of the Oracle games, and its BGM after the Tuni Nut is restored is a calm remix of the Symmetry Village theme.
