A towering gothic castle perched atop a jagged mountain, illuminated by the full moon casting eerie shadows, exuding a gloomy yet majestic aura. The sense of awe and vastness is palpable, each stone intricately detailed under the moon's glow. Enchantment fills the air with a chilling light, enhancing the atmospheric tension, as wisps of mist float around the ancient battlements. An octane-rendered scene where the cold, magical illumination creates a surreal and haunting beauty.
