Equestria doesn't exist. The mortal races of ponies have yet to devolve from alicorns. Gods battle for the control of this young world, using mortals as their champions. Tirek the Destroyer, a being of evil incarnate, is bent on control, that he may relish in the horror and death of the world's races. Lauren Faust, a god who takes the shape of an alicorn, is forced to accept a game proposed by Tirek to save the planet.
To the leader of a dying human race lost in space, Faust comes with an offer. Megan, that very leader, will become a representative piece for the alicorn in a bid to save her planet, Equis, from Tirek . If Megan is victorious against him and his forces, the humans can settle on the planet, saved from a slow death among the stars.
If Megan fails.... Well, there won't be a planet to live on.
[Takes place 20,000 years prior to the Chess Game of the Gods]
