Wall of Coe
A natural cliff face of varying heights that stretches over a thousand miles and runs north-south on the western edge of Cranenthaul. There are few passes through the wall and over time many a king or lord has designated the Wall as the boundary of their kingdom and attempted to control the passages. All such kingdoms have long passed.
The wall is rumored to have been created in a single, great upheaval of earth that was heard and felt across all the land of Cranenthaul many hundreds of years ago, perhaps thousands. Only the oldest of Elves speak of the event. It is referred to in Dwarven and Gnomish lore as The Colossal Rift or The Great Rumble.
