It is the eve of the Harvest Festival. Walk Emberwick with Brakka and Elowen, talk to the locals and step through any door. Inside, the wall between you and the camera fades, the roof lifts and the floors above fold away. Take the cellar stairs and the whole village slices away above you: smugglers' tunnels run under the hills to the wizard's tower, and to a cave in the mountain where something large is snoring.
