Tael

Tael is a fairy in Majora's Mask and is the younger brother of Tatl. He gets separated from his sister at the start of the game and is not encountered again until Link and Tatl venture to the top of the Clock Tower on the last day, where they find him and Skull Kid. His only other appearance before then is in a flashback of Tatl's before Link enters Woodfall for the first time. Tael is a deep purple in color, vastly different from the bright appearance of most fairies. His name and the name of his sister are puns off the word "tattletale."

It is through Tael that Link and Tatl discover that the Four Giants are needed to stop the Skull Kid and Termina from its impending doom. Unlike his sister, Tael has a more innocent and timid personality, unable to stand up to the Skull Kid's constant abuse. Tael also understands better than Tatl all the suffering that the Skull Kid has gone through and why he does such terrible things. While Tatl blames Skull Kid's weak will and a his having no strength of heart for his actions, Tael realizes that it was Majora's Mask that made their friend act that way.

In an act of bravery, after Majora's Mask enters the moon to continue its path of destruction, Tael decides to accompany Link inside the moon because, he says, he doesn't always want to be running away. Tael is stopped by Tatl, who goes in his stead.

Tael is last seen comforting his sister during Link's departure.

Trivia

 * Tael's dark color scheme is unique for a fairy, most of which give off white or gently hued light, and is the only one in the entire series to appear this way, possibly because he is male. This coloration seems deliberately in contrast with the light color scheme of his sister, Tatl.
 * Aside from Leaf from Phantom Hourglass, Tael is the only known male fairy in the Zelda series.
