The Gjallarhorn is a legendary Norse war horn with a semi-realistic, ornate design, featuring intricate engravings of Norse runes and mythical creatures along its curved, metallic body. The horn is large and elongated, crafted from a combination of aged bronze and gold, with a weathered texture that hints at its ancient origins. Its mouthpiece is smooth and polished from use, while the bell of the horn flares dramatically, adorned with a series of small, glowing runes that emit a faint blue luminescence, symbolizing its magical properties.
