Create a realistic medieval-style demonic entity with an unconventional design, avoiding typical horns. The creature should have an eerie, otherworldly appearance: elongated skeletal features, pale cracked skin, and multiple eyes arranged in unnatural patterns. Its mouth should stretch too wide, with sharp uneven teeth, and its limbs should be long and contorted like those of an emaciated beast. Add subtle supernatural elements such as faint glowing runes under the skin, shadowy tendrils drifting from its body, or a slight distortion in the air around it. The atmosphere should resemble medieval dark fantasy art, with dim torchlight and ancient stone surroundings highlighting the creature’s unsettling silhouette.
