The name Morva Tarth (Du.""Marsh of Mist"") was shared by a swamp and a town in northern Rhudaur. These peat bogs lay in northern Rhudaur. A single track lead the through the Morva Tarth, and any who wandered off it stood a good chance of meeting a hidden doom.The swamp was a maze of peat bogs and ponds used by migrating ducks. Some of the bogs were virtually bottomless, and the local Hillmen executed criminals by tossing them hog-tied into the morass.
