Icespire Hold

Icespire Hold is a stone fortress perched on the icy northeast spur of Icespire Peak. A warlord named Jenna Val'Ira built the stronghold, and dwelled there for many years while she and her soldiers kept the orcs of the Sword Mountains in check. When supply lines were cut off by heavy snow and blizzards during a brutal winter, it is believed Jenna and her followers starved to death and Orcs later took over the fortress, which was damaged by an earthquake ten years ago and never repaired.
However during your time investigating the fortress, it looks like the damage was in fact inflicted by The Young White Dragon, Cryovain.
