Yarrow is an awfully loving hunter, who helps lead the pack. Although he isn't Moss's closest companion, he is glad that they share an even more special bond.
Birch Death
Being a first time father, Yarrow knew many things could go south. Despite this he was confident that his pups would grow strong. When he was told of Birch's death his world collapsed. Having an unusual coat, he was overjoyed that Birch shared his characteristics, and had hoped they could grow up to be very close. He grieves with Moss and Elk, and keeps to himself.
