Feathertail is a Riverclan cat. She was chosen by Starclan to go on a quest to save the clans. She then dies on the quest saving Crowpaw and the tribe of Rushing Water. She is then mentioned by Crowpaw when he asks Tallstar to be named Crowfeather in honor of her.
These are two of the main Riverclan cats: Featherpaw and Mistyfoot. Featherpaw is then Feathertail as a Warrior and died from a falling rock on a quest. She is also the daughter of Graystripe and Silverstream. Mistyfoot is the daughter of Bluestar and is Riverclans deputy. She then becomes Mistystar when Leopardstar dies.
