The Altain Corridor: Kroith Passage was once the gateway between North Pines and the Grand Duchy of Rhyl and the Altair Pass to the west that granted access to the western Freelands of the North of the Northern Heartlands.
Balient’s Breach was more dangerous and expensive than Altair Pass, but was an alternative until the Grand Barony fell and the pass became a wasteland and impossible due to the evil spirits that refused to rest – hostile to Lich Lord minion and the living alike.The pass and lands of the barony are a frozen wasteland of roaming spirits, broken bones and everyone that once lived is encased in hoarfrost. Though the ancient fallen barony is on the south side, its frozen covering makes all consider it part of the Hinterlands rather than the Heartlands.
It is cursed, and the very ground swallows the undead, and the biting cold eventually killing anything that lives. Only the spirits of the restless dead wander its confines.
Somewhere in the collapsed pass is the Altairian Mine – The namesake of the region and its primary income source at one time.
