A dark and dramatic depiction of an undead rogue crouching menacingly. His tall, wiry frame is both skeletal and muscular, with sinewy limbs and ribs glowing faintly with neon light beneath his almost black, textured skin that shimmers with a subtle violet hue. His face is obscured by a rough, rusted metal helmet with a grated visor, adding an air of mystery and menace. Sitting in a low, crouched position with wide shoulders hunched forward, he rests his elongated, bony arms on his bent knees. His long, sinewy fingers clutch two jagged daggers that glint faintly in the warm, dramatic lighting. Strapped across his back are crossed katana blades, their handles worn and wrapped in tattered cloth. His shoulders and upper arms emit a faint, smoky vapor, creating an eerie, almost spectral effect. The background is enveloped in a swirling mist and darkness, pierced by a chiaroscuro lighting effect that casts warm highlights and deep shadows across his form. The environment is ominous, cloaked in hazy gloom, with the warm light illuminating his form and highlighting the gritty, sinister details of his undead presence
