The Fairy Stars (フェアリースター Fearī Sutā?, lit. "Fairy Star") is a Keyblade that can be wielded by Terra, Ventus, and Aqua in Kingdom Hearts Birth by Sleep and Kingdom Hearts Birth by Sleep Final Mix and in Kingdom Hearts Union χ by Player.
In Kingdom Hearts Birth by Sleep it is obtained by each character once they clear Enchanted Dominion in their respective storylines.
The Fairy Stars is modeled after Flora, Fauna, and Merryweather, sporting their respective color schemes. The Keyblade's handle and the middle of its shaft are made by a thin, red bar that lines the middle of the Keyblade.
This center bar is framed by two similar and more ornate bars, one green and one blue, that line its sides and curve to create the sides of the Keyblade's guard. Two yellow stars decorate the bottom of the guard and a third is set at the base of the blade. Two small, white fairy wings sprout from the sides of the third star, forming a crossguard.
A large, yellow, eight-pointed star with a ring around its tips is connected to the end of the main blade. The teeth are formed by three five-pointed stars—one red, one blue, and one green—flying off from this large star. The Keychain has three yellow links shaped like stars and the token is Flora, Fauna, and Merryweather's hats stacked together.
The Fairy Stars name is a reference to Flora, Fauna, and Merryweather, the three good fairies from the Enchanted Dominion. "Stars" reflects the numerous stars worked into the Keyblade's design, which are in turn a reference to the sparkles that Flora, Fauna, and Merryweather's magic generate.
