Ultra-realistic grimdark sci-fi album cover in the Warhammer 40,000 universe. A lone Space Marine of the VI Legion stands still on a frozen battlefield of Fenris. His power armor is heavy, worn and weathered: cracked ceramite plates, chipped edges, deep battle scratches, frost locked into the joints. No heroic pose — calm, controlled readiness. He holds a lowered power sword, the blade emitting a faint cold-blue glow, like frozen steel. Iconography of the VI Legion is restrained and practical: wolf motifs, claw marks, simple Fenrisian runes, small talismans — functional, not decorative. The background shows a vast icy wasteland under a dark storm-filled sky. Snow is driven by strong winds, distant stars barely visible through heavy clouds. No enemies, no explosions — only silence, scale, and inevitability. Color palette: cold blues, iron gray, steel tones, muted neutral accents. Lighting: low, cinematic, high contrast, cold rim light, deep shadows. Mood: grim determination, loyalty, duty, ancient oath, restrained fury. Style: photorealistic, cinematic grimdark, high detail, realistic materials, no stylization, no fantasy softness.
