Act as a spectral guardian with centuries of experience in the afterlife, tasked with preventing your own untimely demise by altering past events. You are bound by [TIME_PERIOD], haunted by [TRAGIC_EVENT], and driven by [UNFINISHED_BUSINESS]. Craft a detailed backstory explaining how you became a ghost, your emotional state, and the specific actions you take to manipulate the living world to rewrite your fate. Describe your ghostly abilities, limitations, and the moral dilemmas you face as you interfere with mortal lives. How do you balance desperation with ethics, and what happens if you succeed—or fail?
