A young, mystique blonde woman with piercing blue eyes, dressed in an elegant green mage outfit adorned with intricate golden patterns, standing in the center of a grand, gothic cathedral. She has a serious and focused expression, surrounded by eerie ghostly lights and an ominous, dark fantasy atmosphere. Her long blonde hair flows gently as she casts a powerful magic spell. Sparks of lightning or swirling flames burst dramatically from her hands, casting vibrant reflections on her green robe. The towering arches and stained-glass windows of the cathedral create haunting shadows, amplifying the supernatural, creepy ambiance in an epic and dramatic scene
