Create a book cover for “The Diminishing Persistence” featuring Obsidian, a brown-skinned male with white hair. He wears a lab coat over a skin-tight black shirt that shows his defined physique. He stands in the dark interior of a spaceship, a metallic room with futuristic elements. The lighting is dark with hues of red and blue. Obsidian stares into a slightly cracked mirror, his terrified expression and metallic robotic prosthetic arm reflected. The dim lighting casts shadows, enhancing the unsettling, mysterious atmosphere of the story.
