Hence the whole 'Lost Age' thing. Its not what really happened in our world. But within the fiction it is. A more contemporary example would be the Assassins Creed series, and the 'Those Who Came Before'. Another example would be Middle-Earth if your a fan of The Lord of the Rings.

Essentially its a 'fictional' past that was long forgotten by the time of the 'modern era'.
