Lost Mine of Phandelver
Thundertree was once a community that prospered on the edges of the Neverwinter Woods. However, when Mount Hotenow erupted in 1451 DR, it devastated the small town. In the wake of the disaster, zombies drove off any who survived the eruption. Sometime in the 1480 DR, the zombies have crumbled to dust, but strange magic had turned the local flora into twig blights.
