It starts as an ordinary, warm morning in Ponyville. But soon after all the little ponies get up from their beds something terrible happens: The sun suddenly vanishes from the sky. There are not even the stars or the moon to give light, darkness is a perfect blanket above all Equestria. Our little heroes decide to visit Zecora in hope of getting an explanation for what is happening. But not even the wise zebra knows what brought darkness. And just then, they realize they lost Pinkie.
UPDATE (2016/06/13): Starting soon, I am completely rewriting the story. It is going to be completely changed, and written as a new story. So this one will not be updated and will be deleted by the end of summer.
