The Sirannon

Valley of the Sirannon
(S. "Gate-stream") Stream running west out of the Misty Mountains just above Moria's West-gate. It joins the River Glanduin near the ancient Elven site of Ost-in-Edhil. A pool in the Sirannon guards the entry to Khazad-dum, for it lies close to the door and is inhabited by the evil freshwater Kraken called the "Watcher in the Water". It has been said that the Watcher dammed the river.
