how long is a era
The First Era is a very long Era which lasts for 2,920 years and is marked by a visible shift in power between the Elven and Human races, with the rise of the Cyrodiil Empire. The Second Era begins when the Reman line of Cyrodiilic Emperors is assassinated and the Tsaesci Potentate Versidue-Shaie takes the throne.
