Book of Seals

The Book of Seals is a quest item from The Legend of Zelda: Oracle of Ages. This book is given to Link by an old man in the back of the Eyeglass Island Library in the present. It can then be taken to the past and used on the pedestal in the back room of the Library. Reading the book will instruct Link how to navigate the invisible floor to the next book, and eventually to the old man in the middle. Upon reaching the Old Man, Link will be rewarded with the Fairy Powder.
