Hibestian Range

A mountain range of cold and ice. It takes hearty people to live there. Such as the race of giants that includes Dunstan. Dunstan left the mountains to live in the Sorrowing Court. Giants from the Hibestian Range have a unique ability of creating sparks by rubbing their beards between their hands useful for making fires in such a cold climate. The Vale of Obscurity is a valley in the Hibestian Range, and was the former home of Ice Fairies.

It apparently is a range on the continent of Serenia, and most likely is part of the Great Mountains that seperates the continent into 3 parts. It could be the location of Icebella's realm or could be the location of the Frozen Reaches or another area altogether. There isn't enough information to know for sure.
