Mystical fox on antique books in a shadowy library

A whimsical fox with luminous, moonlit fur sits atop a stack of antique, leather-bound books in a dark, dusty library. Beams of dramatic, cinematic light pierce the darkness, illuminating dancing dust motes. Ornate Art Nouveau patterns adorn the spines. The style is dark fantasy concept art, characterized by profound mysticism and a rich contrast of light and shadow.
