Portray Batman in a dark fantasy world, amidst a gloomy medieval setting

Portray Batman in a dark fantasy world, amidst a gloomy medieval setting. It is among the ruins of an ancient castle, with a gloomy, foggy landscape in the background. His black armor is detailed with spikes and mystical inscriptions, and he holds a large, bloody ax, which appears to have been used in a fierce battle. The atmosphere is charged with fog and rays of light emerging from the heavy clouds. The Bat-Signal glows spectrally in the sky, while Batman assumes an imposing and enigmatic stance, with an almost ethereal cloak that moves in the wind."
