The Shield World of Tranquility. The Planet of Equis. Both are the same. The races of Equis and their leaders, the Ponies, have no knowlegde of their past and their creators, the Forerunners. They, for over three thousand years, went their own way. Until one Princess Twilight Sparkle discovers their heritage, buried beneath Whitetail Mountain. The ponies learn of a species, that faced with extinction, rose and triumphed. They were called, as the ponies learn...

The Reclaimers. Better known as...

Humanity.

And the Equestrian's reckoning with the mythic race may come sooner than expected...and nothing will ever be the same.
