A dramatic and moody square audiobook cover art, 1024x1024 pixels. The central image depicts a single, cracked Venetian mask, rendered in dark, polished wood. From within the cracks of the mask, tendrils of deep crimson smoke or shadow are subtly emerging, suggesting corruption and hidden malice. The background is a textured, deep indigo, almost black, with a faint, cold moonlight glinting off the mask's surface. The overall atmosphere is one of intense psychological tension, betrayal, and impending doom. The style should be painterly and evocative, with strong chiaroscuro lighting. No text, no letters, no words, no title, no author name.
