Shadow Vine, the Daughter of the Everfree, only ever had two friends in her life, Lunar Fire, the Devil Child and Night Wind, the Forbidden One. all three held a secret behind their titles, each kept it from one another, and each nearly lost the friendship of the others because of it. After realizing how close her friendships were to breaking, Night Wind brought them together to end their secrets, learning a valuable lesson in friendship along the way.
but this isn't a story about these three repairing their friendship, this is a story of how this lesson would be needed to save the world from an evil king when he's become far stronger than before.

When Sombra returns and prepares to destroy Equestria, the main six rise with the element to face it, only to fail, but... why?
Harmony is powered by friendship, so when friendship falters, Harmony falls

Shadow and her two friends must rekindle the friendships of the element bearers so that they can defeat the ancient demon, but to do so, they must find the secrets each hides and get the bearers to reveal them to each other. Along the way, they will find themselves entangled in an ancient prophesy relating to six little fillies, the Daughters of Harmony.
When secrets are kept, friendships begin to crumble. When secrets are revealed, true friendships strengthen to surpass all evil.
