The weathered log walls that enclose the outpost curve inward sharply around the narrow walkway that winds between ramshackle homes, pressing nearly flush against the weathered stone of the canyon. High above, the silhouetted figures of the guards on patrol sweep back and forth along the top of the walls, scanning the distance for invading forces. Within the shadow of an overhanging ledge the entrance to a cavern splits the uneven stone of the western wall.
