A demonic demon with horns and a large face stands in the middle of a rocky area

"Create a hauntingly photorealistic image of the demon 'Infernal Herald' standing amidst its nightmarish realm. The demon's form should be covered in intricate, glowing runes that pulse with dark energy, giving it an unsettling and malevolent appearance. The textures on the demon's skin should seamlessly blend with its contorted and grotesque anatomy, exuding an aura of dread. The environment around Infernal Herald should be a twisted landscape of jagged rocks, molten rivers, and obsidian spires. The sky should be a swirling vortex of ominous clouds and eerie lights, casting a dim and harsh lighting across the scene. The demon's dark energy should manifest as tendrils of smoky darkness, adding to its ominous presence. The overall image should evoke a sense of fear, power, and otherworldly malevolence."
