A swordsmith yearned to make the perfect slashing blade, and so he forged a sword from a rare ore mined in Feendrache and tempered it into this captivatingly fearsome shape. Though this particular blade is merely a prototype of the Dragonslayer which Siegfried wields, it is no less sharp or dangerous.
