Shadow assassin king commanding a kneeling spectral army

A lone shadow assassin standing calmly in the foreground, wearing a long black coat fused with living shadows. Cold, focused eyes glowing faint purple. Dual daggers forged from condensed darkness in his hands. Behind him, a massive shadow army rises from the ground—humanoid shadow soldiers, knights, and monstrous silhouettes kneeling in loyalty. Shadows stretch across the ground like black flames, obeying his will. Nighttime ruined city, moonlight cutting through fog, purple-black aura, cinematic lighting, dark anime fantasy realism, ultra-detailed, intimidating presence, assassin king, silent dominance, 4K, high contrast.
