A story of a future generation, set in the Order-naries 'verse.
Reading the previous stories is not necessary.

Peace, Friendship, and Harmony reign supreme across Equestria and the wider world. An entire generation has grown up not knowing firsthand the terror of villains like Nightmare Moon, Tirek, and Grogar. Members of every species can travel, live, and thrive in any place they so desire, and what few problems that arise are easily dealt with by local leaders. In short, everything is perfect.
And Princess Twilight Sparkle, Alicorn of Friendship, the pony responsible for it all, is bored and depressed. Her moodiness affects her two personal students in magic, Bellatrix Lulamoon and Citrine, daughter of Rarity and Ashen Blaze, causing the two to bicker and fight instead of building a friendship.
In a desperate bid for direction, Twilight consults the long-silent Cutie Map, which sends her on a short walk to a big revelation:
Thanks to Twilight, Equestria can handle its own home-grown problems, but new threats of unknown origin approach the peaceful world. To aid the land through a new era of danger and growth, the spirit of Harmony magic itself is forging a new set of Elements, and it will be Twilight's job to find and prepare six new Bearers to take them up, define their virtues, and face the Intruders.

Little does any creature know just how soon the new Elements will be needed.
