Rainbow Dash means the world to Scootaloo, who wants nothing more than to spend every day with her surrogate sister, learning from the best and being awesome together. Yet all that is about to end, possibly forever, and Scootaloo knows there's nothing she can do about it.

The only thing left to do is say goodbye... but that's proving far harder than she ever imagined.

The Ponyspawn have invaded Equestria, and it is up to the newest addition to the Grey Wardens, Twilight Sparkle, to find the means to drive them back! With her friends and allies at her side, can Twilight defeat the evil tide before all of Equestria is devoured?

The Sequel, Pony Age: Catalyst, is available.

When Sunset Shimmer needs some money to get her jacket cleaned and repaired, she decides to take a part-time job to make some cash. She didn't expect to get a rather surprising co-worker, nor did she expect things to turn out quite like they did.

My first Equestria Girls story, happening after the events of Rainbow Rocks. Cover art courtesy of jankrys00.

Luna likes to conduct her own research.

In fact, she has only ever had to ask one question for it.

This story is a sequel to Becoming Them

Manehattan has fallen. The princesses are silent. Coco Pommel and Babs Seed are unlikely partners struggling for survival in what's left of a world gripped by death. As they cling to one another through hope and despair, they pray for the chance to escape and meet other survivors. Then, one miraculous morning, it seems their prayers are answered in the form of a new ship at harbor.

Yet salvation comes at a price neither of them may be willing to pay...

Part one of my collaboration with the inimitable RainbowBob.

You'd think that being trapped in stone would mean that, if nothing else, I could get some peace and quiet. Unfortunately, it seems that Celestia has other ideas.

She has appointed these ponies... these 'Keepers', as she calls them, to keep me entertained during my incarceration.

Honestly? I'd prefer the boredom.

Ponyville has a problem: Twilight's friends all switched Cutie Marks, and the musical numbers are flying thick and fast.
Lyra has a problem: She can't handle the way musical numbers get into your head and take you over.
Bon Bon has a problem with that.

Reviews and other word-of-mouth:
"I just can't find words for how much I enjoy the ideas on display here. … I didn't expect to be rating something this highly, this quickly." –Bradel
"The Lotus Eaters was the story that made me realize horizon wasn't just good, he was really good. Then Fugue State showed me he was really good repeatedly." –Bad Horse
"a strange but intriguing story ... [horizon's] so good at this ponyfic lark that it's still a highly satisfying read. ★★★★" - Louder Yay
"This story is weird, and I mean that in a good way. … [Horizon] thought about how ponies might react if [musical numbers] were a constant in Equestrian life." –Chris

Fugue State now has a sequel!

When a tragic event befalls Applejack, she takes drastic measures in an effort to prevent it. But can a simple farm pony make a difference in the face of an inevitable end?

A story about the sacrifices we aren't willing to make, and those that we are.

This story is a sequel to Princess Celestia Hates Tea

Princess Celestia helps to banish a hoofful of inner demons lurking deep in the heart of a troubled author. Metafiction, again, ensues. Something of a coda to "Princess Celestia Hates Tea".

Now with a Spanish translation by Spaniard Kiwi!

You think you know me so well, don’t you? I’m a spirit of chaos, and nothing else. You don’t even know the half of it! Sit back and indulge me for a little; I’ll make you understand what it truly means to be chaos itself.
