Nyxia, the Nightshade Nymph:

Nyxia, the Nightshade Nymph: Nyxia's ebony hair cascades like a waterfall of darkness, her eyes glowing with an inner light that pierces the shadows. She is a mistress of shadow magic, manipulating darkness to conceal herself from prying eyes or ensnare her foes in tendrils of inky blackness. With a whispered incantation, she can plunge the world into eternal night or summon forth creatures of darkness to do her bidding.
