The Niflheim Frost is a semi-realistic, Norse mythology-inspired weapon with a sleek, elongated blade made from a mysterious, dark blue metal that appears to be perpetually coated in a thin layer of frost. The blade features intricate Norse runes etched along its length, glowing faintly with a pale blue light, suggesting its connection to the icy realm of Niflheim. The hilt is wrapped in aged leather, providing a secure grip, and is adorned with a pommel shaped like a snarling wolf's head, symbolizing the harsh, unforgiving nature of its origin.
