The Dyalynn Mountains create a natural barrier between the Wilderlands on the north and western side and the countries of Shendra and Braemar on the south and eastern side. The Wilderlands stretch west until they reach the Jenari Waste. The Eternal River has its source in the runoff from the Dyalynns, and runs west until it finally reaches Mrala Bay in Koridan. The Wilderlands run from the North Sea in the north to the Deliad Mountains on the border of B'dal.
