Prompt: An ancient, mystical tome titled 'Das Buch der Ewigkeit' resting on a stone pedestal in a dimly lit, serene library. The book's cover is adorned with intricate, embossed silver designs, featuring symbols of life and death like a skeletal figure and a blossoming tree. The pages appear aged, with golden edges, and a faint magical glow emanates from the book, suggesting its powerful contents. The background shows shelves of old books, lit by candlelight, creating a mysterious and scholarly atmosphere.
