We followed him down a steep path lined by trees. I was looking at the ground trying not to trip on any tree roots so I didn't notice we had stopped. I ran into Harry and fell to the ground. I looked up to say sorry to him when I caught my breath. In front of us was a huge black lake reflecting a castle perched on the edge of a cliff. The castle had light pouring out of its windows with towers and turrets shooting into the sky.
