Everypony has secrets and regrets. Some, you can see etched on their faces, others, it's impossible to imagine. So when Rainbow Dash starts acting funny, Twilight and the others are forced to ask, "What could the most spirited pegasus in all of Equestria be hiding?"

After another stunt gone wrong, Rainbow finds herself cooped up in a hospital room again. But when she ends up getting roomed with a nine-year-old colt, her stay at Ponyville General takes a turn that's worth just a little more than reading a book about an archaeologist.

Twilight looked up from the stone. “I’m not exactly sure where it came from originally but there are traces of magic embedded in the stone. Whoever made it was either a Unicorn or an Alicorn. And it was meant to wind up in your hooves.”

Rainbow Dash is having a lazy day when Pinkie Pie gives her a strange stone. Through many trials and discoveries, she embarks on a quest like never before. Her courage will be tested and her heart tried. And she may never be the same again. Only time will tell.

Secrets, they have the power to destroy friendships, topple empires and slay giants. Secrets can be evil, hurtful or even deadly but sometimes, some things must be kept secret for if the world were to know of them then it would bring about its destruction.

The average pony’s secrets could bring a family to ruin or tempt a disaster to strike an innocent town. So, if that is what an average pony’s secrets can do, what can the secrets of a God bring?

A thousand years ago Nightmare moon was defeated but she was not the only evil to disappear all those years ago. Now, that very same evil, one of Celestia’s greatest secrets will be revealed for all of Equestria to see and on that day, that evil will return once again to enact its vengeance upon those who attempted to destroy it so long ago, only this time, Equestria may not survive its brutal resurrection.
