Unknown - The RuneScape Wiki

The Unknown was supposedly all of the dark areas in Gielinor where players could neither travel to nor see. These areas were not connected to the World Map and enclosed areas on the map. For example, there was no map area south of the Kharidian Desert and the vast endlessness of these are displayed with black areas on the world map. It is still possible to see the Unknown by walking to the edge of a Player-owned house (where players who have built dungeons can even see their outer walls with the right camera angle).
