Epic grimdark Warhammer 40,000 album cover, cinematic realism. In front of a colossal gothic Imperial Cathedral dedicated to the Emperor of Mankind, towering spires and statues disappearing into mist. A lone Ultramarines Space Marine in full blue power armor with golden trim stands in the foreground, massive and imposing, bolter lowered, posture calm and restrained. Before him stands a Sister of Battle (Adepta Sororitas) in black and red power armor, fleur-de-lis symbols, purity seals fluttering. They are facing each other at close distance, looking directly into each other’s eyes — a moment of silent recognition, forbidden affection, faith versus duty. No physical contact, only tension and emotion in their gazes. Soft holy light pours from cathedral doors behind the Sister, cold blue battlefield light surrounds the Space Marine. Incense smoke, drifting ash, candles, parchment prayers in the air. Mood: tragic, reverent, emotional, solemn, sacred. Ultra-detailed armor textures, realistic lighting, dramatic shadows, shallow depth of field. Style: dark epic realism, grimdark gothic sci-fi, painterly cinematic illustration. Color palette: deep blues, crimson, gold, stone gray, candlelight amber. Aspect ratio: 1:1, album cover composition, centered figures, highly detailed, no text. Negative prompt (optional): cartoon, anime, low detail, flat lighting, smiling, romance cliché, modern clothes, sci-fi neon, futuristic city, extra limbs, bad anatomy, blurry, watermark, text, logo
