The five eras of Changeling history can be divided into the Mythic Age, the Sundering, the Shattering, the Interregnum, and the Resurgence.
The Mythic Age lasted from pre-history until circa 1000 BC, when the iron age began and mankind realized that they could shape the world through effort and cold hard change. This loss of faith in whim and fancy was the beginning of the end of an age populated by dragons, True Fae, and magic throughout the land.
