Epic grimdark sci-fi album cover, Warhammer 40,000 style. The Lunar Wolves Legion at the height of their glory: white and grey power armor with black and gold details, wolf iconography. Horus Lupercal standing in the center as a noble Warmaster, tall and imposing, wearing ornate pre-Heresy armor, holding a massive power mace. Behind him — ranks of Lunar Wolves Space Marines advancing in perfect formation, banners snapping in the void wind. A dark alien battlefield under a pale moon, broken fortresses and burning ruins in the distance. Subtle shadows creeping across the armor, hinting at coming betrayal. Dramatic cinematic lighting, high contrast, epic scale, heroic yet ominous mood, ultra-detailed, realistic grimdark illustration, no text, no logos, vertical 2:3 aspect ratio.
