How long can two ponies exist in a single mind? It’s a race against time as they search for answers before it’s too late. When all is said and done, you’ll never look at Twilight Dash the same way again.

Just how immutable is fate? In an Equestria where Luna's victory over Celestia came at the cost of also sealing herself in the moon; will the same six ponies rise to return Equestria to a golden age.

Sundude and Moonbro are the most close of all brothers, but their life has some wicked sick surprises in store for them. Luckily, they are chill dudes and know how to handle the situation when things get sketch.

This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Over a thousand years ago, two royal siblings fought for the sky and were exiled, one by her sister's hoof, and one in penance for what she had done.

In the present Republic of Equestria, no one remembers them as anything more than legends and old pony tales. Save for one shy filly who fell from the sky one fine summer's day.

An Alternate Universe "What If" tale, reconstructing the beginning from a different angle.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

This story is a sequel to Scion of Chaos

Five years after the summer in which the three had gotten their cutie marks, Scootaloo, Sweetie Belle and Apple Bloom, now young mares in their own right, decide to go on a quick summer vacation, all as an attempt by Sweetie Belle to cheer up a sad friend. However, the trip turns out to be more than they had anticipated.

Set five years after Scion of Chaos and An Emerald Treasure. For the sake of context I'd recommend reading both of those first.

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.
