Ages

An 'Age' is an undefined period of time, (roughly lasting a few millenia,) which begins with, and ends with, a largely significant event. So far there has been Four Ages documented by the Free Peoples, which are listed thusly-

The First Age- Age of Creation

The Second Age- Age of Fantasy

The Third Age- The God Wars

The Fourth Age- Age of Civilisation

Humans are adamant that the 'Fifth Age,' or Age of Man, has already begun eight years prior to the start of the main storyline, yet nearly all other species disagree with this. Many human critics have also stated that there shall not be an 'Age of Man' until humans once again return to The West.

See this for a semi-detailed summary of the events throughout the Ages.
