Part of The Destiny of the Ancients

The Conversion Bureau was established to transform the remaining humanity into ponies, that way Princess Celestia will take control of the planet and create the utopia of ponies that wasn't possible back on Equestria. It is a gift for some, but a nightmare for millions.

It cause a war where many thought that humanity will be erased in a matter of days; there was no way humanity could come back from the brink of extinction, or is it?

That they survived and were able to push back ponykind is no mere chance as Princess Celestia will realize.

How many times a mere can be allowed to make mistakes? To do the same mistakes over and over again without learning?

There is a bigger force out there, one that has been keeping an eye on Princess Celestia, one that has a particular desire to know more about destiny and how much can a pony change it.

Is it Sunset Shimmer the only one that can walk away from Destiny or is there any way in which Celestia can save ponies?

Who is the voice?

Who is the narrator?

What is the purpose behind The Many Destinies of Sunset Shimmer?
