Eyeglass Island Library

The Eyeglass Island Library is one of the greatest sources of literary material in the entire realm of Labrynna, and is the only significant monument on Eyeglass Island out in the Zora Seas, in Oracle of Ages. The Library's edifice is made of stone and book-shaped, with a large open book for a roof. In the past, it was known to hold Fairy Powder in its depths. When Link first sees the library in the present, it has long been deserted and locked tight, with not even a sign of a keyhole with which to open it up. However, Link must travel to the past in order to obtain the Library Key from the ill King Zora, under a promise to study the books in the Library for a remedy. It is revealed that the pollution of the Zora Seas was laying waste to the entire ocean and threatening the sea creatures including the aquatic Zoras with illness and death (namely their ruler, King Zora, and their patron deity Lord Jabu-Jabu ).

Link reopens the library with the key and eventually discovers that it does indeed contain Fairy Powder, which can be used to revitalize the hallowed Fairy Queen native to the region. However, it is located in a room that can only be navigated when a complete set of books giving directions are present. Link discovers that the Book of Seals is missing from the first checkpoint in the chamber and travels to the present, where he finds his actions in the past has caused the library to now be open to the public. Within, he is able to locate the lost Book of Seals and travels with it back to the past, where he restores it to its proper place and navigates the back chamber to reach the Fairy Powder.
