In a decaying Victorian mansion, Emily, a young historian, discovers a hidden chamber containing a mirror that reflects not the present but a forgotten past. Drawn into the mirror's shimmering depths, she finds herself in a world where history is rewritten, and familiar figures from the past are twisted and grotesque versions of their former selves. As Emily navigates this unsettling realm, she uncovers a hidden truth: the mirror is a conduit for a malevolent entity that feeds on the suppressed memories and regrets of those who enter, seeking to rewrite history in its own image. Emily must unravel the secrets of the mirror and confront the malevolent force before it consumes her and alters the course of history forever.
