Bluestar

Bluestar is a broad-shouldered, large, lithe, hard-muscled, pale grayish-bluish she-cat, with soft, thick, long fur, a broad face and head, silver hair tinged around her muzzle, and tail, a torn ear, a scar that's parts the fur on her shoulders, a long, sleek tail, and luminous, Ice blue eyes.

Apprentices
Bluestar expected to get Whitestorm as an apprentice, but instead got Frostfur. Not much is known about the apprenticeship, as there was a time skip. She trained Frostpaw to become a warrior, and she eventually got her warrior name, Frostfur.

She later gets Firepaw as an apprentice. She forms a good friendship with him, but hard at the same time. She trains Firepaw and he got his warrior name, Fireheart.

Basic Information
Bluestar was the leader of ThunderClan before Firestar and after Sunstar. She is the daughter of Moonflower and Stormtail, and the mother of Mosskit, Stonefur, and Mistystar. She suffered many deaths. Her mother, Moonflower, died because of Hawkheart killing her. Her sister, Snowfur, died because of a monster running over her. She had to have a different mentor which she didn't like for quite some time, and she had to give away her kits to RiverClan so instead of Thistleclaw becoming deputy, she would. She pulled through though, but got some sort of depression at the end of her life as her great deputy, Tigerclaw, had betrayed her beloved Clan.
