Caribou. Once like any other tribe of the peaceful Cervine race, they have made a grave error. In their eagerness to steal the Elements of Harmony, they have badly injured and tortured the Princess of Friendship, Twilight Sparkle. Tended to by her old teacher and dear friend, Celestia, their relationship will bloom into something... more, a relationship to stun the entirety of the nation.
Enraged by the gall of the Caribou, Princess Luna has taken charge of the coming war effort, driving Equestria into producing new arms, new recruits, and new technologies. Despite the doubts of some, and the fear of the return of Nightmare Moon by others, Luna presses on, driven by a desire to reclaim the Elements of Harmony, and avenge the pain of her newest "sister." Will she go too far?
A separate universe from Rekindling and Beats of Life.
Rated sex for clop later on, rated gore for intense war scenes.
