Stormfur and Feathertail are the kits of Silverstream and Graystripe. After their father was exiled from RiverClan, Stormkit and Featherkit grew up taking care of each other. Stormfur often worried for his sister, such as when she began distancing herself from their Clanmates. Stormfur accompanied Feathertail when she was chosen by StarClan to go on a journey to find Midnight, which eventually led to her death.
