Ciela

Ciela, also known as the Spirit of Time and Courage, is a feisty fairy who has lost her memory and serves as Link's partner in The Legend of Zelda: Phantom Hourglass. She awakes Link after he gets washed up on the shore of Mercay Island. Her purpose is to help Link on his adventure. After Link completes the Temple of Courage, it is revealed that Ciela is the Spirit of Courage, and she split her soul in two when she was attacked by Bellum, which caused her amnesia. During the fight with Bellum, it is revealed she is also the Spirit of Time, as well as Courage. She then provides Link with Phantom Spheres, which allow Link to temporarily stop time and defeat Bellum.

After the final battle, Ciela says goodbye to Link and Linebeck. In the game's artwork, she is generally bright blue. In the game itself, however, after being fused with her other half, she is more of a yellowish/white color.

Ciela regularly uses some of Navi's infamous lines, although with far less frequency. Her voice acting is provided by Kaori Mizuhashi, who also voiced Navi.

Gameplay
In-game, Ciela is used as a cursor. The Nintendo DS stylus directs where she goes, and tapping will make Link move, attack, etc. in her direction. Unlike the fairy cursor in the Wii version of The Legend of Zelda: Twilight Princess, Ciela is actively involved in the game's storyline. The other two spirits can also take over when they are active, but Ciela always takes their place to speak to Link. When a Phantom Sphere is activated, Ciela is frozen along with the rest of time even though she IS the Spirit of Time.
