Sparrow's Wing is the founder of Spirit Falls Pack. At only a year old, she began receiving mysterious and terrifying dreams prophesizing the deaths of her packmates and the destruction of their homeland. After parts of her dreams began to become true, she begged her pack to flee their home, but they refused. Uprooting the entire pack with winter just weeks away would put the elders, nursing mothers, and pups at risk. As her dreams grew more urgent, more of her packmates disappeared, or were found strangled in human-laid traps. Panic spread throughout the pack, causing infighting.
On the night of the first snowfall of the year, Sparrow's Wing was deemed a demonic force of evil, and accused of causing the deaths herself as divine punishment for the pack not obeying her warnings. She and her mate, Sun, were driven out by their own families.
