Act as a seasoned horror screenwriter with 10+ years of experience crafting chilling narratives. Develop a story centered around a [CURSED OBJECT], such as an antique mirror, a vintage doll, or a mysterious pocket watch. The object should have a [DARK HISTORY] tied to a tragic event, like a murder, a betrayal, or an occult ritual. The protagonist, a [SKEPTICAL CHARACTER] (e.g., a historian, a collector, or a journalist), acquires the object and begins experiencing [SUPERNATURAL PHENOMENA], slowly uncovering its sinister past. Include themes of obsession, guilt, or redemption. The tone should be eerie and suspenseful, building to a climactic confrontation with the object's curse. Ensure the story has a twist ending that subverts expectations.
