A mythic boomerang-axe features a sharply curved, crescent-shaped blade crafted from dark, polished obsidian. The blade is intricately etched with ancient runes that pulse with a vibrant, otherworldly glow, and further enhanced by elegant brass inlays. Its sturdy handle is made from deep, dark wood, reinforced with several sleek, cool metal bands for a secure grip. The weapon possesses a weighty, ancient feel, with the smooth, cool obsidian contrasting the textured wood and metallic bands.
