Lands of Mystery
The map for the Forsaken Rift comes from Dungeon #136.
Travellers in the far north might come across a crack in a large glacier, a steam vent for a volcano below. Inside this cavern of ice and rock is a small isolated land inhabited by the lost, the exiled, and the outsiders of the world.
Fishing is the primary lifestyle, both in the freezing Frostwash and the more temperate Steamwash. There is little farmland, but with help from druids there are some orchards grown into the forests.
