If you take a close look at this weapon in game, it is actually an Ebony Claymore. (The ONLY one of it's kind!) It features a great soultrap enchantment, and deals a heavy amout of damage! There are two routes you can travel to aquire this piece. 1: Go to Suran's Tradehouse, and from the door of the tradehouse, face east toward the mountian. Levitate over, and you should see an Orc in Orcish armor on the other side of the hill. 2: Leave Suran taking the route south out of town past the manor, then east. Follow the edge of the mountian on your left until you see a path on the left leading up the hill. You should see the Orc in full armor waiting there.

Now that you know your different routes, travel there, and attack him, or talk to him. Either way will lead to a fight. Kill him,, and take it from his lifeless courpse.
