Mount Hotenow was a volcano amid the Crags mountain range, situated to the northeast of the city of Neverwinter on the Sword Coast, deep in Neverwinter Woods.
In 1451 DR, Mount Hotenow erupted, taking out a big chunk of the city of Neverwinter and destroying the nearby town of Thundertree.
In 1491 DR, it erupted once more, destroying much of Neverwinter Wood and killing a tribe of Eladrin that had made its home there.
