"For centuries different factions battled in petty wars and border conflicts, until in 2E 896 Tiber Septim crushed all those who opposed him and took control, proclaiming himself as Emperor. Still, the bitter years of war had its affect on the populace. The name Tamriel, Elvish for 'Dawn's Beauty', seldom fell from anguished lips and was soon forgotten.
