Equus is confronted with a crisis that seriously threatens the future of its denizens. Truly, two major forces, something never seen before, wish to conquer it for different reasons. On one side, you have the Ancients, mysterious beings who claim to be the first settlers of Equus. On the other, you have... the cult of the Dead God Salzar.

Some time in the future, the cult of Salzar is finally defeated. With the help of the Elements bearers, the two pony princesses defeated the deity worshipped by this cult. It proved to be such a hard hit for the cultists, for after his defeat and imprisonment, they became easy prey.

But the war is far from over. As the Ancients march forward, claiming more and more lands by the day, princess Celestia returns to her royal castle. The last known branch of cultists was found and defeated, their coven destroyed and their sacred items burnt to ashes.

Except for one.
