Everypony believes Princess Celestia has always been distant, aloof and dispassionate, but that's far from the truth. She cares very deeply for her ponies, and a tragic mistake long ago made her realize she's not perfect. Since then, she's been careful, nearly over-cautious, until a mother's plea gives her the opportunity to redeem herself in her own eyes, and save another, who becomes a very special pony, one who reminds the Princess that anything is possible, even forgiveness.

Set in the universe of Nathan Traveler's Omnius' Travels: Equestria. Omnius/Nathan/Sean appears with his author's permission.

It's been uncounted millenia since the last of Twilight's first friends passed away. Even their names have passed into legend and myth, forgotten by the slow march of time. Now on a far away planet, she finds her musing upon all of her friends over the long years interrupted by her latest faithful student, Calming Waltz.

Now if she can only get that silly pony off to her wedding, and maybe teach her something about why her romance and wedding to come is so special and wonderous... Or at least something for Twilight to get a laugh out of, anyway.

King Sombra survived his defeat, but just. By the time he returned to form, Twilight became the newest princess of Equestria and the Crystal Empire was restored to its former glory.

He cannot take over Equestria the same way he tried before, but he has a card up his sleeve. Twilight won't see it coming, and Sombra might gain a powerful ally in the process.

And it will all begin...with a book.

After years of learning her new powers and growing into being an Alicorn, Twilight Sparkle has reached maturity. Her loving mentor Celestia feels she is now ready for the ultimate test, to succeed where her sister and herself failed. Celestia reveals the origin of her sister and herself, and tasks Twilight Sparkle to travel across the great sea and take the throne in the land that they were exiled from.

Equestria's beloved ruler, Princess Celestia, Goddess of the Sun and Monarch of the Day begins to look on all that she has created. Together with her loving sister Luna, she created a boundless paradise that united ponies of all kinds under a glorious and prosperous society.
However, during an unexpected and unprovoked attack on the Palace, a single pony stood between the Sun Goddess and her would-be assassin, a Changeling infiltrator. The lowly guard pony gave his life to protect his queen, and it was then that Celestia realised the price of life, and how very precious it is. Unable to bear the guilt of the guard's sacrifice, Celestia finds solice in the only pony she knew the guard best, and one who she knows would understand her - her guard captain, Shining Armour.

Trixie appears once more in Ponyville, but something is...off...about her. She isn't speaking in third person. She is convinced that she is supposed to be the Element of Magic, that Celestia is supposed to be the Tyrant Sun, that Luna is supposed to rule as Equestria's monarch - and that Twilight is supposed to be a wanted criminal. Has she gone insane? Or is something bigger beginning - with consequences that Trixie, Twilight, and two entire worlds, can only guess at?

The long-awaited Crisis on Two Equestrias begins at last!

While reading the stories of The Lunaverse can only enhance your reading experience, it is not necessary for this story! It is being written as completely, 100% stand-alone, with no prior knowledge necessary!

For as long as any of the Cutie Mark Crusaders can remember, Diamond Tiara had always been the biggest bully they knew. But when that said bully dies in an accident, each of them starts to go through their own emotional experience from this sudden change in their lives. Each will learn more about themselves and about the pony who they all thought they knew before she is laid to rest.

***Takes place just after season 3 but before season 4. This story is completed.***

Now with TV Tropes page

Before Twilight ever met her friends, she was just a student under the watchful eye of her mentor, Princess Celestia. But even with her magic, she still needs help once and a while. But what will she do when her assistant is a small baby dragon?

This is the tale of the horrifying days Princess Cadence spent in the depths of the Canterlot caves.

She spends what feels to her like eternity in these caves, unable to escape with no hope of being rescued.
Will her day ever be as perfect as she imagined?
