Eyeglass Isle Library is a location from The Legend of Zelda: Oracle of Ages. A library on Eyeglass Isle, Link must visit the building to progress in his adventure. The Eyeglass Isle Library can only be opened by using the Library Key on the keyhole in the past. Inside are many Old Men who tell Link of the surrounding seas and of the Fairy Queen who has recently gone missing. In the past, they also speak of a Fairy Powder in the back, but say that it is unreachable due to the missing Book of Seals. After obtaining the book from the present library, Link can navigate the maze in the back room and obtain the Fairy Powder.
