A mysterious and epic album cover set in the grimdark Warhammer 40,000 universe. Corvus Corax, Primarch of the Raven Guard, standing in full height, half-emerging from deep shadows. His armor is matte black with subtle battle damage, raven motifs and pale reflections, eyes glowing faintly with cold intelligence. His silhouette partially dissolves into a swarm of spectral ravens and shadowy smoke. Dark gothic sci-fi ruins in the background, broken spires and floating debris under a moonless sky. Dim blue and violet lighting, strong contrast, heavy chiaroscuro, cinematic composition. Atmosphere of secrecy, vengeance and ancient fear. No text, no logos. Ultra-detailed, high realism, dramatic lighting, epic dark fantasy sci-fi, album cover art, 4k, sharp focus, painterly yet realistic style. Optional negative prompt: bright colors, smiling, heroic pose, cartoon, anime style, low detail, flat lighting, modern clothing, sci-fi helmets, text, watermark, logo
