Go to Silvar. There should be a weapons store that is closed there. Bash down the door. Go behind the counter and try to walk into the walls. You should find a secret door with two special encounters (white circles). The first tells you that the room is full of dust, the second will inform you of a trap. After the trap, search the nearby crate by standing adjacent and looking into it. You can now take a shiny new short sword from the crate.
