Walks into Skara Brae.
Circles around the town taking in the fencing, houses stalls and other built artifacts.
Stops on the bridge. Inspects the posts and planking. Kneels, watching the townsfolk. Using a hunting knife, scratches and gouges at one of the main posts. As the afternoon comes and goes, steps back to check the marks.
Nods and leaves Skara Brae.
