The Unquiet Earth
The Tamed Lands are bound to the north by the Dragonspine Mountains and to the west by the Verdent Mountains. In the north-west, where the two mountain ranges meet, there is a deep pass and a nearly bottomless ravine. This is where the gods of Lyramet cast the Rift created during the Enclave Coup. The portal to all the dark and unpleasant realms outside of Lyramet spews forth death, undeath, twisted creatures, and dark magic.
The Bloodfist Dwarves and the Thunder Walker Tribe (mostly humans and shifters) guard the pass. The effects of the ancient blight still affect the area, and the lands just inside the Tamed Lands at the pass are barren and full of sickness. The dead walk in the blight, as do all manner of creatures beyond description.
