photorealistic, ultra realistic, real photograph, An ancient, malevolent entity known as the Nightmare Weaver. It has an ever-changing, surreal appearance with a body made of shifting textures and colors. The form includes patches of shimmering scales, ethereal fabrics, ghostly metallic surfaces, and floating, ghostly images of broken landscapes and swirling mists. The entity has intense, glowing eyes--one piercing blue and the other a deep, malevolent red--and a twisted, gaping maw that flickers between a grin and a snarl. Extending from its body are ephemeral appendages resembling skeletal hands, tendrils of smoke, and flowing ribbons of light. It also has phantasmal wings composed of tattered, ghostly fabric and ethereal light, adorned with glowing, ancient runes and symbols that pulse with a faint light.
