Fiadh is a near-perfect doppelgänger of her mother, Finley. Her coat is a mixture of greys fading to white on her underside complete with white throat, cheeks, and socks. She has a distinctive charcoal stripe down her back. Her lemon yellow eyes are the most striking difference. She is a physically fit wolf of medium size with even proportions. A variety of nondescript scars are a clear sign of her reckless lifestyle.

She is impulsive and rash but mostly harmless, with a tendency to stir up trouble for thrills and attention. Fiadh is fun-loving and intense. She makes fast friends with those who can keep up with her antics, but is both susceptible to and guilty of peer pressure. She loves to joke around and pull pranks, taking nothing seriously. Fiadh has a level head on her shoulders when she chooses to consult it, which is rare.
