History of the World of Avatar

To further clarify the often confusing timeline in Avatar: The Last Airbender, this timeline dates events as on a scale of years, with the year Sozin began the war set as year 1000.
 * Note: The events after "The Boy in the Iceberg" and prior to the "The Guru" may not be appropriately set, as the only concrete date given in the show is that of the Day of Black Sun (1 August).
