The Tree of Harmony, guardian of the Everfree and holder of the Elements of Harmony. The Crystal Heart, an artifact that provides a magnificent light in the skies to protect the north.

Seven pure lights to protect Equestria from all evil.

When the tree is destroyed and three suspicious ponies arrive in Ponyville, it is up to Twilight and her friends to uncover a secret, which is older than Equestria itself, to prevent the darkness from swallowing their world.

This story takes place after KH:3D and after season 4 in MLP.
Rated teen, just in case my language or the themes drift into darker realms here and there.

Thanks a bunch to pileoblock and zimmerwald1915 for proofreading and editing this project and supporting me.
