Tundrabristle is a gloomy, snide but elegant she-cat who grew up in Summitclan with her Brother Mesarill. Her parents were extremely absent and always disappearing from Tundra and Mesa, so she never truly felt like a part of any family. Due to her parents, she had a fear of being alone which often led her to become obsessed with others and jealous if they give time to anyone else. While she had many friends, she felt still alone, especially after her brother went missing when they became warriors. This made something in her snap and she tended to violently lash out and spend hours wandering the territories alone in search of Mesarill.

Her obsessive ways eventually led her to Witheringsnow, a brooding and quiet tom like herself who she enjoyed the company of a little too much. He found her on one of her hourly walks and felt a kinship in feeling like an outsider. It wasn't long after that they rushed into a relationship, Tundrabrstle desperate for someone to never leave her and the need for a family. They both had no idea they were setting themselves both up for a dark future.
