Soul biter, Elemental Sword

Zalag, master elf craftsman with intricate, silver-tipped braids and emerald green leather apron, amidst a fiery forge, shapes a radiant sword with a blade that shimmers like polished obsidian, its core ablaze with inner fire, as water-like rippling patterns dance along its length, while earthy, moss-covered runes etch its fuller, and wispy air currents caress its tip, infused with the essence of a rare, otherworldly metal, aethersteel, forged in the heart of a fallen star, as elemental energies swirl, imbuing the sword with an ethereal glow.
