The Vastness Mountains is a mountain range on Ardon that is mentioned in Crusaders of Might and Magic. It lies north of The Glaciers, and prevents the icy weather from reaching the northern realms. The dwarven realm of Corantha is located within the mountain range, and has been carved into the stone over centuries. The airship pilot Aerrin was born and raised in a small village in the Vastness Mountain foothills, until she was cast out for her "craftiness and strong-willed behaviour".
