PROMPT:
Create a hauntingly beautiful Gothic-inspired image that exudes mystery and opulence, set within a grand, dimly lit cathedral with intricately carved stone walls and towering stained glass windows that filter shafts of vibrant, emerald green and sapphire blue light. Incorporate lavish, ornate details such as gilded accents, velvet drapes, and ancient, leather-bound tomes scattered across ornate, wooden pedestals. Amidst the grandeur, a lone, enigmatic figure clad in dark, flowing attire stands at the edge of a majestic, crimson-hued carpet, surrounded by an aura of mystique and foreboding. Employ a predominantly dark color palette, punctuated by bursts of vibrant, jewel-toned hues, and strive for photorealistic textures and lighting to transport the viewer into this eerie, mystical realm.
