A young mystical blonde woman with piercing blue eyes, standing in the center of a large gothic cathedral. She has a serious and focused expression, surrounded by eerie ghostly lights and a dark and sinister fantasy atmosphere. Her long blonde hair flows softly as she casts a powerful magic spell. Sparks of lightning or swirling flames emanate from her hands, illuminating her entire body in an epic and dramatic pose. The cathedral's towering arches and stained glass windows cast eerie shadows, amplifying the supernatural and spooky atmosphere.
