In a not-so-far past, Princess Blackhole and her sister, Princess Eclipse, once ruled together with a firm conviction that they could make Equinox a perfect place for their ponies. Queen Blackhole had a long and flowing blackish mane and tail, both representing a rather shadier side of the sun. Her eyes were of a golden hue, however, and her cutie mark was that of a black circle surrounded by swaying lines.This mark was supposed to represent her conviction in bringing in all the evils of the world and destroying them. Her sister, Eclipse, however, had a rather brighter and more orange appearance, her physique representing that of the sunset. Her mane and tail flowed just like her older sister's, and within it sparkled the little twinkles of early stars. Her eyes were just as golden, though, which said much about their close connection. Eclipse used a more direct approach as to bringing to heel all evil. Her cutie mark was that of two crescent moons touching at their centers. Although not of much significance, it showed the two sides hidden by a moon when a sun covered it during the rare events each year.

Yet, despite their best efforts, the two sisters could not avoid a war to come. In the wastelands of Equinox existed a strange race of creatures called the Gorgonis. These pony-esque creatures possessed three eyes on their face, a hair made of serpents, and a snake's tail. They had similar powers to the Gorgon of ancient myths, showing where this race's name came from, atleast by some ponies. Others believe that the myth stems from them. Whatever the truth, they were more than capable of turning any who looked at them in these eyes into stone. They weren't as colorful as the ponies, although they still had colors more alluring to simple forms of stone, such as yellow or gray. They wanted to take over Equinox and expand their statue collection, which the sisters said no to. Therefore, a war ensued with the Gorgony soldiers turning everypony they met into stone.

The beginning of this war wasn't looking good until somepony found a way to protect themselves from their glare, which brought the war to a stalemate. Death was abundant. Even the war machines, like catapults and trebuchets, weren't enough to break the line. There were breakthoughs here and there, destroying much territory for both sides, which brought grief and distress. Several gorgonies preferred to leave their country to live in more peaceful regions. Several believed that Equinox would win the war, which is why they would plan their leaving in secret. Of course, as the adults could turn any living being they looked at into stone, they had to devise a method of protecting the others around them. Blindfolds were the simplest method as they could still use their serpents to see around them, although not with the same peripheral vision or detail.

When a gorgony left its country during times of war, this was considered treason, and they would be banished afterwards. However, since certain families were still found out, they would recieve a punishment defined by the gorgonies of that settlement. The results were grueome, to say the least. As the war neared its end, Equinox and Eclipse took everything in hoof personally and went to battle the leader of the gorgonies: Black Entity. Being alicorns, these beings destroyed much of the gorgony army and made a path straight for the castle of Black Entity which laid within a mountain wall. Although, even after storming the castle with their troops, the mares did not find the leader of the gorgonies, and raised the flag of Equinox atop the flag post, proclaiming the Equinoxian victory. However, the throne room was filled with an indistinguishable black mist. This would have repercussions on the princesses later on.

As time passed on, the two princesses began to change appearance, and not for the best. Blackhole grew two new pairs of eyes, the four smaller one underneath the original. These eyes had become pure red, and Eclipse's body had become darkened, although her mane and tail retained their black outlines with the weird, viscous membrane possessing bizarre black dots swimming around in it.

Eclipse, however, had only grown a second pair of eyes, but they remained golden, although they stretched more along her face and had a shape similar to a crescent moon, although barely. Her coat had started to become a dark mist and her mane and tail had turned into what looked like ink within water.
These transformations weren't immediate. They were progressive, and the two sisters suffered through them rather painfully.

"It's not mine yet. I need it all."

Blackhole paced along in her room, the dreary setting of this place bringing about a powerful strength of fear. The bed had begun to distort and twist while the walls began to take a sinister, smoky appearance. Everything seemed to be turning into a nightmare. Even the tapestries on the walls began to mutate the pictures, showing what was once a simple pony posing for a picture to have become a dark abomination of its former self.

"I've grown tired of her. She will have to leave, whether of her own accord or not. Time to go, Eclipse." the alicorn's smile grew.

Being careful not to alert anypony, the alicorn left her room and walked through the still normal walls of Kestrel Castle. The mare slithered through the hallways, avoiding the gaze of the servants and guards, as Blackhole wanted to show herself once she could do what she wanted, the pony reached the room of her sister at the other side of the castle, although she was not in it. She was overlooking Equinox from her balcony. She seemed distressed about something, so, as any real sister would do, Blackhole came to her 'aid' with soft steps.

"Sister?" Eclipse asked aloud.

"Yes, Eclipse. I sensed a disturbance. Are you alright?"

"No. I feel a darkness growing within me. It gnaws at my mind. I fear I might succumb to it one day."

"Do not fear, dear sister. If we are together, nothing will corrupt us. We will stand strong like the mountains against the wind."

"I did not see you as much of a philosopher, dear sister." Eclipse said.

"Because I see the future, and it is grand." Blackhole's voice took a menacing tone.

"But how can we see that future if we show ourselves as we are now? Perhaps this was the plan of Back Entity. Our ponies will no longer accept us"

"Then we simply have to get them to see themselves as they see us."

"What-HRNGH!"

Eclipse had turned around to see her sister impale her with several black spikes coming from the membranous portion of her mane. It was the black dots that had done it. Blackhole simply simply looked at her with a smile filled with her jagged teeth. Eclipse tried to utter a word, but she simply crumbled upon the floor, lifeless. Her eyes showed that their owner felt hurt by betrayal from a family member rather than the stabbings. Sometimes, emotional wounds subsist more than physical ones, and this held its all as well.

Taking a moment to take in what she had done, the remaining alicorn turned away and called one of her subjects who slightly cringed at her frightening appearance.

"Send an announcement to the citizens of Kestrel City that I will be making an announcement within the hour."

"Yes, m'am." the stallion executed.

After said hour, the alicorn poked out from the curtains to witness an immense amount of ponies waiting for her and mumbling to each other about what was going on. They were all very curious as they hadn't seen her and Eclipse for several months. Putting on a royal composition in her appearance and all-around presentation, the alicorn came out from behind the curtains and stepped upon her balcony to greet the huge crowd of ponies awaiting her announcement. She was met with huge gasps of shock and surprise. Many mumbled about what had happened to her. Was she cursed? Had she become something more? Was she a mutant?

"SILENCE!"

The crowd obeyed.

"I have called you all here to share some things with you. One, is that my sister has been killed by some vile pony."

"An uproar began.

"I don't know who it was, but he or she will be find."

Rumors about it being a gorgony began.

"The second is that I've noticed that many of you have been feeling too compressed. You've all hid away your true abilities and nature, and I have a way to free them all."

One of the ponies stepped up and asked:

"What do you mean? I mean, I understand that many of us have sides we wish to hide, but that's for our better well-being and those of everypony around us."

"But that is exactly the reason why you were invaded and had such trouble pushing the Gorgonies away until my sister and I intervened."

"Then how do you propose to 'cure' us?" the pony asked with irritation.

"During our storming of the castle, Eclipse and I came upon an empty throne room. After entering it, we came to a realization."

"Wait, is that why you look like you are?"

The alicorn smiled.

"I will free you of your corruption, and you will love our new world, ruled by Queen Blackhole of Vereor Castle!"

The alicorn rose high into the sky, then spread her wings apart. There was a resonating thunderclap as her mane and tail literally exploded and threw a weird black smog everywhere. The air was being invaded by the wave of monstrous gasses that devoured the clouds and sky like a ravenous parasprite. Not being special, the sun was just as much a victim as everything else. Blackhole laughed evily as she watched the crowd begin to run in panic and try to flee the castle grounds, but it was futile. To their dismay, instead of slowly rising upwards and descending at about the same speed, the smog suddenly burst outward, engulfing the whole of Equinox in a matter of moments. Everypony stopped in their tracks as they began to mutate and change, turning into contorted, nightmarish versions of their former selves. But, you know what? They didn't care. They felt liberated. A new reign had begun in a better world...At least, better for those accepted by the Queen's gift.

Author's Notes:

Okay. The first chapter of the story with a rather descriptive detailing of events. The other chapters will have the usual build with details, character dialogue, and so forth. I tried my best to fill in the gaps of the Equinox Kingdom, so, I hope you like this story.

Epic Brony 4 Life helped me narrow down what we could of the Equinox Kingdom.
