In the First Age all of its inhabitants followed Guthix. Later during the Second Age it became part of Zarosian Empire, but after his fall it became a Saradominist region for a short period, as a large flood cut of all ways of getting there, that caused it to become forgotten. At the late Fourth Age the Forgotten Wilderness became the target of various necromancers, who used its remote location to be safe of the mainland humans. The region has 4 (formerly 5) settlements.
