Thundertree was a small town nestled among the foothills of the Sword Mountains, along the Neruda River and near Neverwinter Wood. Thirty years ago, the nearby volcano Mount Hotenow erupted. The town was spared from direct damage from the volcano, but a plague of undead spread throughout the region and Thundertree was abandoned. Today, the undead are still present in the town, which has been overgrown with plant life taking root in the ruins. The forest seems to have begun to reclaim claim the town for its own. Worse, a observant traveler might notice upon approach that there is an eerie stillness and silence filling the space between the trees; whatever that portends, it can be nothing good.
