Feathertail was a RiverClan warrior under Leopardstar's leadership in the forest territories. Featherkit was born to Graystripe of ThunderClan and Silverstream of RiverClan alongside her brother, Stormkit. However, her mother died during the kitting, and after being temporarily fostered by Goldenflower in ThunderClan, Graystripe took his kits to RiverClan where they were fostered by Mosspelt. As an apprentice, Featherpaw was mentored by Mistyfoot, and after being held prisoner with other half-Clan cats by Tigerstar, she, along with Stormpaw and Mistyfoot, escaped to ThunderClan where her temporary mentor became Sandstorm. She fought in the battle against BloodClan before returning to RiverClan.
Following Tigerstar's defeat, Feathertail became a warrior and befriended Sasha when the former rogue joined RiverClan with her kits; however, she broke ties with Sasha after finding out about her relationship with Tigerstar. When she received a dream from Oakheart, Feathertail journeyed on a quest to the sun-drown-place and grew close with Crowpaw on the journey. Thereafter, when Feathertail was revealed as the silver cat destined to save the Tribe from Sharptooth, she died dislodging a stalactite from the cave roof, killing Sharptooth in the process. Mourning her death, Crowpaw asked to be named Crowfeather in her honor. She ascended to StarClan and reunited with Silverstream, and she also resided in the Tribe of Endless Hunting. She watched over Leafpool and convinced Squirrelflight to raise her kits, loving them as if they were her own. She gave Bramblestar and Mistystar one of their nine lives, and later ventured into the Dark Forest to defeat Ashfur.
