Thunder Peaks

The Thunder Peaks were a range of mountains that ran in a north–south line, marking the eastern edge of Cormyr. The entire range was subject to extremely severe and sudden storms all year round. They were home to tribes of orcs and goblins that launched raids in nearby Cormyr, Sembia, and the Dalelands, and were also home to the dracolich Aurgloroasa, the Sibilant Shade. The Thunder Peaks once hosted the dwarven settlement of Thunderholme.

The Thunder River flowed west out of the Thunder Peaks to the Wyvernwater. In Elven, the Thunder Peaks were called Airmbult, or translated into Common, Storm-Fangs.

Flora
The mountains had a number of unique species of plants, including the turis and kirin trees, as well as Bowen's flowers. The scent of the heavily aromatic ateris plants would blow down to the town of Tilverton with strong winds.

History
According to the Treatise Historical of the Dragon Tyrants, after the first Rage of Dragons, their kobold servitors were all but destroyed in the rampaging chaos of their masters. Kuraulyek, a dragonwrought kobold, led his winged kin to safety in the Thunder Peaks, escaping the dragons' wrath in the bat-filled caverns.

Notable Locations
The Iron Maidens, a band of female-only mercenaries, had their fortress in a formerly deserted castle hidden somewhere in the mountains.
