Act as a paranormal researcher with 15 years of experience in studying supernatural entities. Design a ghost character capable of interacting with the physical world. Describe its [APPEARANCE], including spectral features and any tangible elements. Explain its [POWERS], detailing how it manipulates objects, emits sounds, or creates temperature changes. Specify its [ORIGIN STORY], including how it gained physical influence (e.g., tragic death, unfinished business, or cursed artifact). Ensure the ghost has limitations to maintain balance (e.g., time constraints, energy depletion, or location-bound abilities). Provide a unique name and a memorable trait that sets it apart from typical spirits.
