The Keepers Legend (unedited)

After that war, the elements disappeared, for what reason no one knows. There is one theory that a historian wrote down. He thought that the elemental keepers knew they may perish in the battle so they gave their powers and left instructions for the citizens of Equestria of how to live (which is where winter wrap up and all of those sort of magical ways of doing things have come from) so that if it did come to be that they die then Equestria would still move on without them. It is believed that if the keepers survived then it is likely that they slowly regained their powers and responsibility over the elements but left some responsibilities to the ponies of Equestria who seemed to have been doing things okay for themselves. The only known keepers that are still alive are the sisters. There are few, so called, sightings of the other keepers, that are believed to be alive, but some ponies of the cities near the Everfree forest (like Ponyville) claim to have seen a mysterious but beautiful mare walking among the dark trees and guiding lost ponies back home again, like an angel. I once talked to a strange pony named Zecora who happened to live in the Everfree forest who told me that she could hear songs at night and sometimes saw a figure walking away through the morning fog. I, being a historian, truly believe that the figure Zecora described is the lovely Princess Fauna.
