Exiled from her birth pack after attacking her mother, who had murdered one of Belladonna's pup siblings, she comes strutting into the Wolves of the Willow's pack territory without any shame. So, when she runs into Moonchaser herself, she's snapping and growling before the other wolf assures that she won't hurt her. In fact, Belladonna is invited to join the pack. She's hesitant at first, but realistically, she knows she can't live on her own and she doubts any other pack would take her. The stubborn wolf settles in quite well, being the dutiful and more strict pupsitter of the pack. Her love for pups, and her new rank, gives her the urge to have children of her own. So, she turns to a fellow pupsitter, Glacier, for help. She asks if he can be a surrogate father to her puppies, which he agrees to, as at this point in time he was not mates with Moonchaser. Belladonna would later give birth to Jonah, Winddancer and the deaf Honeydew. She treated all her pups the same, not coddling nor loving either of them more than the other, and now she's the proud mother of two of the pack's best hunters and Rusty's deticated scoutmate. She also becomes Rusty's mate later on, although the two do not plan to have pups. Meeting him singlehandedly changed her mind on being in a relationship, welcoming it due to Rusty's charming and attentive mature.
