"A series of overlapping wars among constantly shifting alliances, precipitated by the death of Artur Hawkwing and the resulting struggle for his empire. It lasted from FY 994 to FY 1117. The war depopulated large parts of the lands between the Aryth Ocean and the Aiel Waste, from the Sea of Storms to the Great Blight. So great was the destruction that only fragmentary records of the time remain. The empire of Artur Hawkwing was pulled apart, and the nations of the present day were formed." (TEotW,Glossary)
