Shortly after Twilights coronation the Tree of Harmony was almost destroyed when the seeds Discord planted all those years ago sprouted. The Tree of Harmony and the Everfree Forest had always had a yin-yang connection. At a time before the royal sisters rule a noble soul had sealed her essence into the tree to trap a powerful enemy inside the Everfree Forest, leaving behind the Elements to give strength to those who came after her. When the tree was on the brink of being wiped out the spirit within began escaping. Now the effects of its influence are threatening to engulf Equestria. Can their combined power defeat the spirit formerly sealed away? In the battle they may learn that they possess a power far stronger than the Elements of Harmony.
