When Celestia and Luna first settled into Equestria and became the goddesses, they had wanted a place where the subjects they ruled over could be safe, and they got just that. However, they did not get all of it. The Everfree Forest is a place where no pony ever dares venture unless they are either brave or stupid, and there is a reason as to why. Ever wonder where the Legend of Gaia Everfree came from?
