Frostfell

The Frostfell, or Elemental Plane of Ice, is one of many Planes of Existence in the Critical Role universe.

Notable Locations
There was once a rift in the Frostweald leading to Frostfell, through which Errevon invaded Exandria in a war referred to as the Icelost Years.

History
Errevon and an army of creatures from Frostfell invaded through the rift in the Frostweald, taking advantage of the weakened state of the continent following The Scattered War. The Icelost years ended when rift was ultimately sealed by a combination of forces from the Republic of Tal'Dorei, Syngorn, Kraghammer, and the Ashari. This event is celebrated yearly in Tal'Dorei as Winter's Crest.
