Twilight and her friends know the routine. The Cutie Map summons one or more of them by making their cutie marks glow and flash. They come to the castle to answer the summons then depart to some distant part of Equestria to solve a friendship problem. They've all done it many times before.

But whose cutie mark is that? It's not anypony in Ponyville. Or anypony Twilight's friends have met.

What's a pony to do when one morning their cutie mark starts glowing, and they have no idea why?

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.

Princess Twilight Sparkle had just sent her star pupil off to the same village that marked her first steps into learning how powerful friendship can be by making new friends. A big decision that has started to make her question her own friendship among her friends. So when the Cutie Map suddenly signals her, her friends, and even the Young 6 for a new friendship mission, she takes it to herself that she makes the best out of the situation, especially when the location of the problem takes place at Silver Shores.

Meanwhile, Luster Dawn struggles to keep her studies up afloat as she is constantly distracted by her new friends. With these distractions, her dedication to ever completing the princesses's task grows lower and lower, as she tasks herself to find out what a mysterious text on the school's new history book meant.

As both Twilight Sparkle and Luster Dawn grow more tangled into their own problems, they both realize the answer to their question as a new threat to Equestria, a threat that will once again push the magic of friendship to its limits...

After a particularly nasty run in with a monster during a mission from the map, Twilight discovers that she has apparently gained immortality due to her ascension as an alicorn. With this realization, Twilight and Spike go to visit the Royal Sisters to study immortality and get some advice.

Instead, Twilight finds herself flung into a whirlwind of confusion.

Now featuring significantly less errors! Thanks to everyone who pointed those out in the comments, and if you see any more feel free to point them out too.

This story is a sequel to Queen Chrysalis Reforms (Accidentally)

Tiatarta! The hidden gem of Equestria’s resorts. Sandy beaches, colorful locals, and relative isolation make this the ideal vacation destination. So what kind of friendship problem could this tropical paradise possibly have for Smolder and Ocellus to deal with?

And what the HAY is Queen Chrysalis doing here?! And what did she do to her mane?

Reading Queen Chrysalis Reforms (Accidentally) is recommended for context.

Fluttershy and Rainbow Dash's newest cutie map mission really bugs them.

Another entry into the Fimfiction Feghoot Festival. (No filk this time, though.)

Part of the Remember Fort Libris print anthology, thanks to our Kickstarter supporters!

Celestia, now completely controlled by her evil side, has defeated her sister and trapped the World in an everlasting day, and plans to rule over it as Supreme Empress Daybreaker. She has trapped the Crystal Empire, and made any form of communication impossible for Twilight. The Cutie Map calls for the young princess and her friends to stop this disaster before it's too late.

There is a strong argument to be made towards the Map's lack of a proper understanding of priorities.

This story is a sequel to Guarded Emotions: Burying the Past

Captain Shining Armor and Captain Moonwhisper. There are many similarities between the two stallions. Both are among the most powerful of the unicorns in Equestria's Royal Guard. Both are romantically tied to an alicorn princess. And, strangely, both were completely absent during the Storm King's invasion of Canterlot. In Equestria's hour of need, where had these stallions gone?

The answer, as it turns out, involves a friendship mission in a remote corner of the Equestrian wastes.

This story is a sequel to A Talk With the Tree of Harmony

With the Tree of Harmony gone, the Map in Twilight's castle has gone dark and, despite her best attempts, Twilight is unable to reactivate the Map now that its source of power is gone.

Until one day, when her and her friend's cutie marks suddenly begin to glow with a slowly fading light, like a dwindling soul crying out for help...

Proofreading done by RQK and the cover art was provided by Ultra-the-HedgeToaster

After being called by the Cutie Map to stop an incident in Ponyville, the girls discover a stallion being pursued by the worst kind of girl imaginable: a tsundere. How can this possibly work out well? It probably might not.
