The Black Citadel

Before any of the orcs look up to see you standing there, you pull out and quickly invoke the properties contained within the scroll. A surge of energy fills your body then erupts from the ends of your fingertips. Lightning arcs out across the air to hit the first three orcs. As your body is still shaking from the massive amount of energy you're producing, the arc of lightning hits the other orcs in the room to join them all in an electric circle of death. The electric current stops and the dark one and all the orcs fall to the floor as black, smoking, charred bodies.

On the orcs bodies you find 6 gold coins. You see the lever again, pull it down and the wall in front of you swings inwards to reveal a small dark corridor.
