Thornwood

The Thornwood was a forest by the Lake of Steam.

As of 1372 DR, it was inhabited by evil humanoids and at least one beholder. There was a legend that every ten years, in a particular grove in the forest, the Green's Sword would sprout and could be claimed by anyone using it to fight evil.

By 1369 DR, the Twisted Rune had placed a magical gate in the forest to allow for instantaneous movement to other locations.

The River Minta flowed through it from Erlkazar to the Lake of Steam and out to the Shining Sea.
