G3 ponies in G4 universe.

Hi, the name's Maurice, and I happened to be unlucky enough to get transported to a world which is inhabited by aliens that suspiciously resemble colorful horses from my world...

Thorax has defected to the land of Equestria, taking thousands of changelings with him. When Chrysalis launches a retaliation against Equestria, Twilight and her friends must repel her invasion with one thousand changeling volunteers.

After seeing what happened when she accidently changed her friends destinies, Twilight is curious about about the 'what if'. Like, for example, what if Luna had ponies a thousand years ago who noticed her.

Trixie's cruise trip was ruined the moment she met up with Pinkie and Sonata. After they got stranded on a desert island due to a hurricane, Pinkie and Sonata were trying to have fun while Trixie was determined to get herself off of the island.

Friendships don't always last, time isn't always well-spent, and not everyone gets a happy ending. Everypony has their regrets, paths not taken, failures and lost loves. Sometimes, it's too late for second chances.

Shining Armor and Cadence's spell reveals something completely unexpected.

A chance discovery gives Twilight Sparkle the opportunity to share a very special secret with Trixie Lulamoon, and hopefully prove that it isn't just blood or marriage that are powerful ties that bind.

This is the story of a bond forged between three fillies and the many trials and tribulations that strengthen that bond as they grow older. Friendship, secrets, and a dark journey awaits.

The most dangerous creature is summoned by Twilight Sparkle thanks to a dark foreshadowing.

In the age of Equestria's founding, the world is not at peace. Dangers wait at every corner, and the shadows of the old world wish it dead. And yet in all of this, one pony just wants to live a normal life.

Rainbow Dash has spent nearly five years away from Ponyville, fighting and dying alongside so many other Equestrians, when a piece of home unexpectedly appears at her hooves.

"What is an alicorn you ask? Where did they come from? How do they work? Well... if you're having trouble finding the answer to your questions, then perhaps you should sleep on it. Maybe then you'll find the answers you seek..."

A zebra leaves her home to make a reputation for herself, discovering allies and enemies among her kin and the droves of ponies slowly claiming her planet for their own.
