Ultra-detailed grimdark Warhammer 40k artwork. Imperial Inquisitor standing in the center, waist-up or full-body, illuminated by harsh sacred light. He wears a long dark leather coat with heavy buckles, a high collar, and a red-lined interior. On his head — an iconic Inquisitorial peaked cap with a polished metal aquila badge. His face stern, relentless, hardened by countless purges. Purity seals and parchment wards attached to his coat, fluttering in the smoky air. In his right hand — an ornate bolt pistol or inferno pistol glowing with righteous fire. In his left — a massive tome of judgement bound in iron, or a glowing power sword. Background: colossal gothic cathedral of the Imperium, towering arches, stained glass shattered by holy fury, drifting ash and incense smoke. Behind him silhouettes of burning heretics or twisted xenos shapes fading into shadow. Volumetric lighting, deep shadows, embers in the air. Color palette: black leather, crimson, gold, brass, bone-white parchment. Hyperrealistic textures: worn leather with cracks, weathered metal, scorched purity seals. Mood: dramatic, authoritarian, holy dread, cinematic. Composition reminiscent of AAA Warhammer art, 8k realism, razor-sharp focus, ultra-detailed grimdark aesthetics.
