Serpent Hills

The Serpent Hills were a range of rocky hills in the Western Heartlands of Faerûn, bordered on the north, west, and south by the High Moor and on the north, east, and south by the Serpent's Tail stream.

Geography
The peaks of the western Serpent Hills broaden out and eventually level out to become the High Moor.

Geographical Features

 * Beneath the red-clay hills was a system called the Serpent Tunnels, partially consisting of tombs from around the time of Netheril's fall.
 * Deep below the Serpent Hills, in the Underdark, was the grimlock city of Reeshov.

Inhabitants
The Serpent Hills were once filled with life but later turned into a dry, lifeless land inhabited only by reptilian beings.
