The Tyrfing Sword is a legendary weapon with a blade forged from dark, almost black metal, featuring intricate Norse runes etched along its length that glow faintly with a blue mystical energy. The hilt is wrapped in aged leather, secured with silver bands, and the pommel is adorned with a large, polished sapphire that pulses with power. The sword's design is both elegant and menacing, with a slightly curved blade that tapers to a sharp point, ideal for slashing and thrusting.
