Snow is the Daughter of her
pack leader, she's very young but already feels the pressure from her father to possibly someday lead her pack. This makes her nervous, as she'd much rather spend her time exploring the grasslands, picking flowers, and smelling herbs.
She more closely resembles her father than her
sister, and has a silver marking on her nose that he has commented on as "rare", Snow believes this is the reason why her father wants her to lead and has learned to hate her marking.
