Mount Hotenow erupts

Geological / environmental event

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.
