A legendary assassin’s dagger crafted from an unknown shadow-infused metal. The blade is slim, double-edged, and emits a faint dark-purple glow, with runic engravings that pulse like living shadows. The hilt is wrapped in obsidian-black leather, with a subtle, curved guard that resembles the wings of a shadow beast. The weapon radiates a cold, deadly aura, leaving behind a trail of black mist with every movement. It looks both elegant and terrifying, designed for speed and precision.
