Sierra, the Fairy of Courage, is the fairy that helps Link in Phantom Hourglass. She begins the game as a white fairy. By collecting 10 green orbs and offering them at Fairy Island, Sierra can allow Link to shoot lasers from his sword. Collecting 20 orbs doubles the width of the laser.

After beating the Temple of Courage, however, instead of a yellow fairy, another white fairy appears. Link goes to Shiwan, who uses his staff to fuse the two together, revealing that Sierra is the Fairy of Courage. Prior to the game beginning, Sierra split herself in two to prevent Beramuu from sealing her away.

In the final boss fights, Sierra provides Link with Phantom Spheres, allowing him to temporarily freeze time. The final scene before the credits is Sierra saying her goodbyes to Link and Lineback.
