The Dark Lady has only appeared in Sieur Jacques-Alphonse's dreams.
She covers her body and face in a hooded robe of fine black fabric. Her hands are quite pale, and have long red nails painted red. Her voice is husky and deep, yet profoundly feminine.
She has always warned Sieur J-A not to trust (Princess) Roxanne, nor the Arch-Duke, that his cousin Francois is racing to his doom, and that his primary loyalty should be to himself, his second to his family. She repeatedly entreaties Sieur J-A to trust her and let her help him.
An ancestral Bois-Alsante has accused her of being a/the "drab of the Western Ocean".
