The Northern Wall is a major mountain range that separates the temperate lands of the south from the glaciers of the north. Though some maintain a nomadic life on the ice, few people live above the Northern Wall.
Though an uncommon event, on occurrence qlippoth from the Abyss crawl out from under the Northern Wall by using the planar tears that appear in the Darklands below. The Zarzian elves in Laurentia and the nomads of Kalahan maintain a watch for the arrival of these creatures, in order to fight them back and close the portals when required.
