Letters from the Beyond

You’re a historian who has recently received a haunted piece of correspondence from a particular era. What does it say?

In this prompt, the goal is to weave an atmosphere of historical authenticity and a plot of chilling ghostly happenings. The letter from the past could be a plea for help, a confession, or perhaps a prophecy. Themes to explore include the truth behind ghostly interventions, the anxieties of the past, and how historical events shape the present.
