Ascendants Rising - A Forgotten Realms Campaign
The Thunder Peaks are a range of mountains that run in a north-south line marking the eastern edge of Cormyr. The entire range is subject to extremely severe and sudden storms all year round.
The Thunder Peaks stand on the border between Cormyr and the Dalelands, with Sembia just to the southeast. Since Sembia’s expansion, the Thunder Peaks and the road through them has become riddled with dangers.
Zekknar says that inn elven; the Thunder Peaks are called Airmbult, or translated into common, “Storm-Fangs”.
