This is Shadow Bane, the sword of Erion's best friend and lieutenant, Elantir. It is also a magic blade like the Light Hammer. However, unlike Erion's sword, it isnt a Sheenix blade. Elantir used it in his days as a monster, bounty hunter. Its a large, single-edged blade, with a very long handle. It resembles a spear more than a sword.
