Piles of ancient stones, shaded by the overhanging branches of the oak forest and now half-covered with dirt and moss, mark the border of the river that flowed through the valley millions of years before. Moonlight filters through the branches overhead, dappling the leaf-covered ground in an ever-shifting pattern of faint light and shadow.
