Fort Oak was ground zero during the destructive Age of Rifts 2. Numerous battles took place along the Forts walls to repel incoming Rifts that seeked to decimate what was left of the unfortunate town of Oaks Rest. The destruction wrought across the landscape beyond the Forts walls was at a level unseen since the first Age of Rifts.
Ultimately, the mortals were successful in their defence of the Fort. However, a short time after their victory the fort was abandoned in favor of starting over with a new town which became known as Voyagers Wharf.
