This story is a sequel to Growing Pains

After a magical mishap involving a filly, magical empowerment, and an aging spell, Twilight finds herself stuck with a rather large problem.

When Princess Celestia shows up to help her out however, it becomes apparent that Twilight isn't the only one affected by her new looks. Which in turn brings back feelings she had long thought forgotten.

Reading the prequel to this story is not required though it does help.

Enjoy.

Princess Twilight has come back to the other world to catch up with her five human friends (and one pony-turned-human friend).

What could be better than visiting Sugar Cube Corner, talking about the latest goings-on while sharing a brew with friends?

Trigger Warning: The word "Anonymous"

Some three centuries after Twilight Sparkle's coronation, something stranger than anything in Equestria's history appears in the very heart of Equestria itself. A human, lost, confused, and alone, finds himself warily welcomed by the rulers of this strange land.
After trading information about himself for information about the world he'll soon call home, he leaves from Canterlot to the quaint and quiet town of Ponyville, where he eventually meets a lonely bat-pony by the name of Speck.

First main installment in the Tutelary Spirit universe. Recommended reading order: Loyalty, Honesty, Generosity, Kindness, Laughter, and Friendship.

Many ages after the original adventures of the Elements of Harmony, a young stallion soars high into the clouds, searching for the Element of Loyalty.

Her original life lived and gone so long ago, Loyalty, like the rest of her friends, has changed and grown over her many lifetimes to guide the ponies of Equestria.

Because even after so long, the Elements of Harmony will always share their lessons of friendship.

When Maud Pie officially endorses the latest party game to hit Equestria, Pinkie can't wait to share it with her friends.

For all the wrong reasons, it's a game they won't soon forget.

The trendsetter so controversial, 60% of FimFic's mods ruthlessly crushed the subsequent bandwagon!

Stuff said about CAE:
"I never knew I wanted this until now!" - Xomniac
"Despite your vileness, I can't stop laughing at this fic!" - Professor Tactitus
"Illuminati confirmed." - AlesFlamas
"So weird, I reviewed it twice!" - John Perry

Rated Teen, but brace yourselves for some rather 'near-the-knuckle' humour and strong-ish sexual references. Oh my.

This story is a sequel to When the Stars Align

After the most bizzare week of her life, Starburst, the daughter of Princess Twilight Sparkle, finds herself in a relationship with Starfall. Despite their personalities being opposite of one another, she agreed to go on a date with the unicorn, and fell asleep next to him feeling happy and safe.

But will this relationship survive the test of time? Between Starfall's not so great beginnings in Ponyville, his tragic past, Starburst's family's attitude, and, worst of all, her friends' merciless jokes, does it even stand a chance?

What does their future hold?

This story is a sequel to The Guardian of the Night

The newly formed Star Guard has been given an impossible task: purge the world of the Nightmare Forces once and for all.

Pipsqueak, Captain of the Star Guard and Guardian of the Night, must lead a select few through the dreams of, not only ponies, but all sentient creatures. Acting on Princess Luna’s behalf, Pipsqueak has vowed to travel the lands of Equestria until his impossible task is completed, no matter the personal cost.

But the Nightmare Forces lurk in every shadow and every dream, waiting for Pipsqueak to falter. Can an earth pony, not gifted in magic, fight against the darkness? Only time will tell.

This story is a sequel to Twilight's Escort Service

Ratchette runs a one-pony fix-it shop for enchanted conveniences and devices, the only such facility in Ponyville. Some of her services are limited ones, and there are things she has to refer elsewhere -- but on the whole, she puts the majority of the repair traffic in order and in the two years since she first moved to the settled zone, Ponyville's become used to her. But strangers in town can still have a little trouble with her qualifications. Because her mark says she's perfectly suited for her occupation --

-- while her body claims exactly the opposite.

(Part of the Triptych Continuum, which has its own TVTropes page and FIMFiction group: new members and trope edits are welcome. While this story is technically a sequel, the earlier one just has the main character's first appearance, and this piece can be read as a stand-alone.)

Now with author Patreon and Ko-Fi pages.

Mis-communication has started many a war, but in this case maybe calling it a war was too generous.

The "war" is over, Twilight has successfully orchestrated a bloodless end to the Griffons' aggression, but only now does she realize that there is more to winning than she had first assumed, especially against a nation that holds war as a central part of their culture...

Now Twilight must deal with the aftermath while facing a challenge she never anticipated: being seen as a conqueror.

This can be read alone, but I recommend reading the letter that started it all for a chuckle and a little exposition. This series of expositional one-shots can also give some additional world-building.
