You are following a small woodland trail in the Emerald Forest. The hear the sound of moving water to the west, and squinting a bit intently you see a blurred outline of a small wooden bridge in the distance. Who built that bridge? And why? Only a few seasoned rangers have ever come this deep into the enchanted wood, and none ever mentioned the existence of construction of a bridge. As far as you know, the forest has resisted gently but firmly all attempts at colonisation or lumbering, which makes it quite a curiousity.
