Hoard of the Dragon Queen
Volcanic Mount Hotenow is situated to the northeast of the city of Neverwinter on the Sword Coast North, deep in Neverwinter Wood. It is home to a large population of fire elementals, warming the Neverwinter River to the point where it never freezes over, even in the heart of winter (hence the city’s name).
In 1451 DR Maegera, a primordial held in slumber through the craftsmanship of the dwarves of Delzoun and the elves of Iliyanbruen at the heart of Gauntlgrym, briefly awakens, causing Mount Hotenow, a long-dormant volcano, to erupt. A pyroclastic flow destroys the city of Neverwinter. Only the Winged Wyvern Bridge survives the destruction relatively unscathed.
