The Shimmering Island is an island located by Esto Gaza on the Lost Continent in Final Fantasy IX. Situated to the south of the Lost Continent, the Shimmering Island appears at first to be a collection of glaciers.
Shimmering Island is a gateway between the world of Gaia and the world of Terra that exists inside it. It is unknown whether it formed on its own as a side-effect to the failed Fusion attempt, or if Garland created it. According to the Final Fantasy IX Ultimania Shimmering Island began glowing 1800 years ago marking its opening as the portal between the two worlds. This was the time the world's calendar began.
The light of the Shimmering Island is the radiance of the crystals emanating from the dimensional interval where Gaia and Terra are joined, and is the subject of religious faith for the inhabitants of Esto Gaza, who call it the "Spirit Road". When the gate to Terra is open, the radiance is at its greatest.
The party obtains four elemental mirrors from Ipsen's Castle. Traveling all across Gaia, the Hilda Garde III drops off two party members at each elemental shrine, where the guardians of Terra make their abode. The four are living seals to the entrance to Terra, and after they are destroyed, the Shimmering Island reveals a glowing, multicolored portal. The party may access the portal via the Hilda Garde III.
After Kuja destroys Terra, the gateway nested on the Shimmering Island closes, and it regains its former icy appearance.
Zidane's ultimate weapon Edit
During endgame, Zidane can get his Ultima Weapon by using a Dead Pepper at the place where the island used to be, while riding Choco. Shimmering Island remains marked on the large map view, where the player must position themselves right at the center where the island is marked to find the treasure. There are no bubbles unlike in the other ocean treasures.
- The Shimmering Island portal no longer shimmers in the mobile/Steam/PS4 versions; in the original, the opened portal used to shift between white, purple and blue.
- When the Hilda Garde III enters the the proximity of the Shimmering Island, the teleportation field is in a distinctly triangular shape with a circle at its center, representing the seal of Terra.
