Tyranny of Dragons
Volcanic Mount Hotenow is situated to the northeast of the city of Neverwinter on the northwest Sword Coast, 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 the Year of Knowledge Unearthed (1451 DR), a small adventuring party rediscovered the ancient dwarven city of Gauntlgrym beneath the volcano. The party, consisting of Dahlia Sin’felle, Korvin Dor’crae, Valindra Shadowmantle, Athrogate, and Jarlaxle Baenre, made it all the way to the legendary forges. There, the latter two were betrayed by their Thayan allies, with Athrogate hypnotically forced to activate the forge. This briefly awoke the primordial Maegera, who, in a fit of rage, released a burst of energy so powerful that it forced the eruption of the volcano. The resultant earthquake and combination of smoke and lava destroyed much of Neverwinter, killing thousands.
