The North is a land of windswept, frozen tundra interspersed with plots of land made arable by lost technology. Barbarous tribes wander the waste while civilization gathers in its last refuges, always hungrily seeking the secrets of the past in order to survive.
All the enemies of Creation seem drawn to the North. The Deathlords have the largest shadowlands in the world here. The Fair Folk are always threatening on the edges and causing rampages with their wyld-tainted cannibal tribes. The Realm’s few Satrapies here are hellish places where slavery is mandatory and the desire for freedom is quelled by copious drug use.
Yes, great darkness threatens the North, but in the face of such things great heroes must arise. You are these heroes.
