The Dark Iron Sword is a sleek, medium-length weapon with a dark metallic blade that has a subtle, ominous glow. Its design features sharp, angular lines with a slightly curved edge, giving it a menacing yet elegant appearance. The hilt is wrapped in dark leather, providing a secure grip, and the guard is minimalistic with a small, dark iron emblem embedded at its center. The blade's surface is smooth with faint, etched runes that glow faintly when wielded, hinting at its dark power.
