Goddess Crest

Goddess Crests are objects from The Legend of Zelda: Skyward Sword. Magical crests bearing the image of an avian creature, these were left behind by the goddess Hylia to aid her chosen hero. Goddess Crests are activated when they are struck with a Skyward Strike, causing a variety of things to occur depending on its location.

Story
Shortly after learning the art of the Skyward Strike from Fi Inside the Statue of the Goddess, Link must use it to activate a Goddess Crest found near an Ancient Tablet; this causes the Ancient Tablet to clear a path through the Cloud Barrier, allowing Link to travel to Faron Woods. Goddess Crests are subsequently found within several dungeons, where they are used to retrieve other fragments of the Ancient Tablet. They are also found within the Isle of Songs, where they activate the Goddess Statues found there, allowing Link to learn new songs for the Goddess's Harp.
