A serpentine sword with a blade that twists and curves like a snake in motion, shimmering metallic scales etched along its surface. The hilt is ornate, with a detailed snake's head as the pommel, its fangs bared and eyes glowing faintly. The handle is wrapped in dark leather with golden accents, and the guard flares out like a serpent's hood. The setting is a mystical, glowing background with an aura of magic and danger, ultra-realistic, 4k resolution. --s 750
