Tael
From Zelda Wiki.org
Spoiler warning: The following contains key plot or ending details.
Tael (トレイル, Trail) 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 (for the most part) not seen 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 white or cream appearance of most fairies. His name and the name of his sister are puns off the words "tattle" and "tale".
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 did such terrible things. While Tatl blames his weak heart and will for all of the Skull Kid's actions, Tael realizes that it was Majora's Mask that made their friend act that way.
In one act of bravery, after Majora's Mask enters the moon to continue its path of destruction, Tael decides to accompany Link inside the moon, for he mentions that he does not want to spend his life running away from everything. Tael is stopped by Tatl, who goes in his stead.
Tael is last seen during the game's ending as he is comforting his sister after witnessing Link's departure.
