As I'm not familiar with 'the lupine woman story', she might be a unique individual within the story's setting. She could be a local legend, someone who has a magical or spiritual connection to lupines. For instance, she might be able to communicate with the lupines or have some sort of power that is related to them. Or perhaps she is just an ordinary woman whose life is deeply intertwined with the presence of lupines in her environment, like a farmer's wife who has a special patch of lupines on her land and she has a strong emotional bond with it.
Since I haven't read the 'the lupine woman story', it's hard to say exactly who she is. However, she could be a character that the story revolves around. She might be a woman who has had a life - changing encounter with lupines. Maybe she was lost in a forest once and the lupines guided her out, and since then, she has dedicated her life to protecting them or spreading their beauty. She could also be an artist who is inspired by lupines and creates amazing works of art based on them, and through her art, she becomes known as the lupine woman.
