This story is a sequel to Celestiphobia

It's only been a day since the treaty was passed, and Stan still hates the ground-walkers and fliers and magicians. So his friend, Carl, decides to cheer him up by making him take part in his favorite activity. Getting drunk.

What a horrible mistake that was, since it gave Stan beer goggles for a certain white alicorn, and has him running around causing mischief at every turn.
Carl can only hope he can survive the night.

Now with deleted scenes!

Author's words with some form of intelligence: Now with 100% more editing by Alticron

Well it's not actually a sequel. Here is a collection of short stories and histories detailing the life of Alternia, a changeling queen impersonating the life of Princess Celestia. These are the stories of the ruler under her mask.

Reading the main story: Princess Celestia: The Changeling Queen is a requirement if you don't want to be spoiled or confused. I will try to provide background information when I can.

For readers of the main story, there are basically no spoilers if you've read past chapter 8. Enjoy!

This story is a sequel to The Three Sisters: Extended Family

A story of The Three Sisters Universe

Families are like fudge — mostly sweet with a few nuts. ~ Unknown Author

Chrysalis' daughters are serving their community service in Ponyville. Nothing can go wrong. Right?

Unless they all have their own agenda, and surprises keep piling up, complicating matters further. But anything to broker peace between the Changeling Nation and Equestria... right?

Art by the incomparable Conicer!

Now with a TV Tropes page! Warning: Will Contain spoilers.

Weevil and Echo are a married changeling couple who, amongst thousands of others at a time of mass migration, have left the Changeling Kingdom in search of a better life in Equestria, the so-called 'land of love, tolerance and opportunity'. Now Equestrian citizens and living in Six Points, a diverse and deprived district in Lower Manehattan, Weevil and Echo have opened their own business and are trying their best to raise their family and simply live their lives

Of course, raising a family is never easy wherever you live, especially in this bizarre urban jungle populated by friends, enemies, and all out crazies. But through it all, Weevil keeps a level head, an unwavering dedication to his friends and family and his values, and by doing so will come out on top out of whatever this Celestia-forsaken city throws at him.

Hopefully.
