Not to be confused with King Gale.
She evidently grew up in the lower classes of Narrowhaven with her parents and aunt. When she was about ten, her mother was kidnapped by slavers. Gael and her father chased after her, but were unable to save her before she was taken away and sacrificed to the Green Mist.
Gael also smuggled herself on board the ship, but was found a few days later. She was, however, permitted to join the crew without punishment.
Afterwards, she was given a bunk with Queen Lucy, whom she quickly grew to admire and respect. The two developed a sisterly relationship as they traveled on to the east, visiting a magician and his servants, surviving a hurricane, and weathering the attack of a dragon in the search for the mystical Blue Star that would lead them to Gael's mother.
The dragon was discovered to be none other than Eustace transformed, and Gael and some of the crew stayed on land with him. At one point, while she and Lucy talked, she told Lucy that she wanted to be just like her when she grew up, unknowingly echoing Lucy's earlier desire to be more like her elder sister Susan. Lucy answered her by sharing the lesson she had learned on the voyage; that a person should grow up to be like themselves.
During the long fight against the monster, Gael was several times rescued from danger by Lucy, who sent her to their cabin and bade her to hide there.
After the fight, the hostages of the Mist and Dark Island were freed, and Gael and Rhince were reunited with Helaine. When they saw her, after the Mist cleared away, they both leaped into the sea, and swam out to her.
It can be assumed that after being reunited with her mother, the three of them including her father all returned to Narrowhaven where they lived out their lives.
- Gael is not in any of the books, and thus is only canon to the movies' continuity. She is a character created by the filmmakers and portrayed by Arabella Morton.
