The Dark Iron Sword is a sleek, medium-sized weapon with a slightly curved blade, featuring a dark metallic finish with subtle crimson accents along the edges. The blade's surface has a rough, textured appearance, suggesting it's forged from a unique alloy, while the hilt is wrapped in dark leather for a secure grip. A distinctive design element is the glowing red runes etched near the base of the blade, which pulse faintly, hinting at its magical properties.
