The One Ring: The Nameless Fellowship
The Black Tarn
Around the Dusky River, and especially along the Black Tarn, live many river-birds, and fishes in plenty swim under the surface of the waters. The river forms a natural boundary against the Spiders, who dare not cross the water. The Woodmen keep careful watch on their northern and southern borders to stop Spiders creeping around the river, and must be equally careful when boating on its surface. The Spiders cannot swim, but sometimes they crawl out onto branches that overlook the stream and dangle sticky strands of webbing down into the path of approaching boats, like monstrous fishermen.
