Fan Casting Mrs. Dark in The Shadowhunter Chronicles: Epic Fancast

Mrs. Dark was tall and thin, her hair almost colorless. She, like her sister, wore bright clothes and gloves, used to hide their clawed hands—their demon marks. According to Will, she was not much to look at, and even her true demon form was an improvement. Mrs. Dark's true form resembled a large, repulsive stone statue because of her hard, gray, stone-like skin. She had horns, three rows of mouths with greenish fangs, twisted limbs, clawed hands, and yellow eyes that burned with a sulfuric glow.
