One might argue that with her strong belief in freedom, Ternwing would have been a prime candidate for the League. And she had indeed been approached at one point, but decline the offer.

With this in mind, there is a lot more to Ternwing than meets the eye. On the surface, Ternwing is a sweet, gentle mollie with a very compliant and kind personality. In reality she is a very strong willed, opinionated cat who could easily go toe to toe with many cats. Cats, after all, often made the mistake of thinking that she was the weaker between her and her sister, Tigerfang.

She was killed while protecting Tigerfang from League rogues, a decision that she doesn't regret. In StarClan, she mostly spends her time with her mother, Grousestep, and her father, Sandclaw.
