Great War

Great War may mean several things:
*Great War (Elder Scrolls), a large-scale armed conflict between the Third Aldmeri Dominion and the Fourth Empire during the Fourth Era. 
*Great War (Fallout), a global thermonuclear war caused by the Sino-American War. It resulted in the destruction of all participating nations and abroad, global disruption of climate, and billions of casualties as a result of nuclear blasts, exposure to radiation, and subsequent collapse of social and government structures.
