 Ingimundr's rationale for seating himself upon an island (Lewis and Harris) on the edge of the kingdom may have been due to the fact that he was unable to gain any authority on Mann itself.In fact, the chronicle reveals that civil war erupted there the following year, and the chronicler Orderic Vitalis indicates that Mann was devastated to point of being a virtual desert by the time Magnús appeared on the scene.The warring itself may have been related to the aforesaid factional struggles between Guðrøðr's sons.
