Dark fantasy oil painting concept art. Surreal, gritty, textured. Matte finish. A mysterious sorcerer figure floating slightly above the ground. He wears heavy, layered robes that are turning into black smoke and starry constellations at the bottom. Where his head should be, there is a floating geometric shape (a black cube or sphere) surrounded by magical runes. He holds an open book that glows with violet light. An infinite, impossible library with floating bookshelves and flying papers. Atmosphere: Cosmic horror, mystical, silent. Deep purples, blacks, and cosmic blues. High contrast magical lighting. Style of Elden Ring (Raya Lucaria) and surrealist art.
