The four elemental crystals have been the source of the world's prosperity for as long as anypony - or anyone else for that matter - can remember. The strong earth, the bright fire, the abundant water, and the brisk wind have been with ponykind since the beginning.
However, for the first time in history the crystals are being threatened. A great evil stirs, willing to destroy the energy of the planet itself in order to achieve its goals. The effects can already be felt worldwide - something is wrong with the wind.
The fate of the world is placed in the hooves of four mares chosen by chance - a princess, a wanderer, an amnesiac, and a pirate. They are about to set out on an adventure that will take them further than any of them could have ever known.
This is Pony Fantasy V: Exodus of the Void.
