Vast Swamp

The Vast Swamp is an area of swampland that separates Cormyr to its west from Sembia to its east. It is flanked to the north by the Thunder Peaks mountains and to the south by the Dragonmere, a body of water. The swamp is inhabited by beholders, small black dragons, gnolls, hobgoblins, lizardfolk and will-o'-wisps amongst other things, but neither Cormyr nor Sembia have any particular interest in laying claim to the land.
