A terrifying spectral figure emerges from the darkness inside an old, dimly lit cathedral. The ghostly entity has a skull-like face with hollow, glowing red eyes that pierce through the shadows. Its mouth is open wide, revealing sharp, menacing teeth. The being’s form is composed of ethereal, flowing smoke-like tendrils in shades of purple and deep blue, blending into the darkness around it. Its bony hands extend forward with sharp claws, as if reaching out. The cathedral setting is filled with tall pillars lined with stained glass windows, pews, and faintly glowing candles, which flicker from the presence of the supernatural being. Papers are scattered through the air, caught in the eerie, swirling mist. The overall mood is dark and mysterious, with a supernatural energy emanating from the spectral figure.
