He is a wandering Rito minstrel who will play the accordion and sing an ancient verse to Link , telling him the location of several shrines throughout Hyrule. Link can encounter Kass at certain stables where he offers to sing Link an ancient song of Ganon's defeat 10, years prior. Spoiler warning : Plot or ending details follow. He is the student of a Sheikah who was the court poet of Royal Family of Hyrule before the Great Calamity and is traveling the land to fulfill a promise he made to his teacher who is implied to have passed away at some point in the years following the Great Calamity. However, he was forced to leave his wife Amali and children in Rito Village and longs to fulfill his promise in order to return to them. As a Rito, Kass is capable of flying, an ability he presumably uses to travel across the vast expanses of Hyrule.
Kass' Theme (From "The Legend of Zelda: Breath of the Wild")
Zelda Breath of the Wild has more than a hundred shrines for you to find in its wonderful world. By now you probably figured out that you can use your Sheikah Slate radar feature to locate shrines once you get close to them. While adventuring through Hyrule I came across a bird man named Kass playing his accordion or is it a concertina?
Breath of the Wild. Kass is an accordion-playing Rito from Breath of the Wild.
