Thornwood

This forest is one of the most dangerous in south western Faerûn. It is inhabited by evil humanoids, dangerous plants, and at least one Beholder. Wood elves, Druids, and Treants struggle to hold back the tide of evil. Legends tell of the Green's Sword, a green blade that sprouts from a particular grove every ten years; the sword can be claimed to fight evil by one who is worthy. The grove is encircled by brambles and is otherwise only remarkable for the sword-shaped leaves of the plants where the sword appears.
