Equal and Opposite

A long time ago there were six ponies, the six pillars of Old Equestria, Rockhoof the Strong, Flash Magnus the Brave, Somnambula the Hopeful, Mage Meadowbrook the Healer, Mistmane the Beautiful, and Starswirl... the Bearded.

They were the countries most powerful defenders, and when one of there own turned on them they disappeared. But not without leaving behind a gift for the future, a seed. This seed grew into the now well known Tree of Harmony.

But at the time there is a theory that was not well known, 'For every action, there is an equal and opposite reaction'. This magical theory has since been proven true multiple times since then.

As the tree grew one of its roots grew far faster, and far further, until it began to sprout up and out of its own cave far outside Equestria. This root, once in its cave, began to mach the speed of growth for the tree. It grew up and out wards, until it looked like a four storey tall, and wide, dead bush.

And as the Tree of Harmony developed the Elements of Harmony this 'bush' began to grow the opposite. The Elements of Disharmony. However it could not make items meant to be used by others like the tree, so it made its own wielders and made the elements in their hearts.

First was birthed as nothing more than a dark shadow, making the all ready deep and dark cave nearly impossible to see in. It was Cruelty, and it took on the name Umbra the Shadow of the World.

The next grew from the root in a glowing green pod, it caused a number of other pods to grow and lines of green to shoot thru the 'bush'. Ghastly images appearing on the walls from their sickly green glow. The largest pod broke open and unceremoniously dropped a being covered in green slime onto the floor. The creature rose from the ground revealing its self to be a grotesque and twisted form of an alicorn, holed legs and insectile wings with a crooked horn. And so was born Deceit, the first of her kind, many names she took but the most prominent was Chrysalis Queen of the Changelings.

The third was a ghostly being only visible in the realm of dreams, its appearance mutable to serve its purpose. It was Despair the Tantabus, Nightmare.

The forth and fifth grew as one and the same, the twins Betrayal and Greed. Betrayal took the form of gargoyle and the name Scorpan, and Greed became a twisted combination of a Minotaur and a Centaur with the name of Tirek.

With the first five birthed they left fleeing each other and the sense of death that came from their 'mother', and with those five gone the roots could finally create the last. However it could no longer from living beings on its own, and so it reached out with its foul magic and influence to cause a number of creatures to come to it with parts of their dead. And from those parts and creature that strayed to close, it made the final element. Solitude, a being like no other.

At first Solitude was content to remain alone in the cave. However like all living beings he began to want for company, and so he left in search of companionship but all he found was fear and discrimination. If they were going to treat him like a monster then he would become the monster. And so began the age of Discord the Lord of Chaos.

"...And the rest is history." The being, no creature, no not even that described this thing, he-it was a monster, finished recapping the story he forced me tell.

It took in a deep breath and leaned over me to release it. "Oh my," Its smooth and husky voice began. "So many think that the smell of fear is something made up in order to scare the non-predatory races. But I can tell you right now that is not the case, would you like to know what fear smells like? It smells like you right now, your sent mixed with the smell of urine and a primal pheromone." Another deep breath and the monster began again. "I oh so love it when my prey doesn't even try to hide their fear. It makes them so much easier to track down and kill."

I try to say something, anything, but I can't I am paralyzed with fear. Unable to move speak or even whimper he stands back to his full height. "Don't worry, my little pony" He says with statistic glee. "You did your job well. This village meant to guard this... 'bush' of disharmony did rather well. I had to fight thru so many to get this far, and kill so much. Would you like to know what I did?" It pauses as if expecting me to answer him. "No? Awell, I guess listing me go on and on about how I went from house to house killing all inside, men, women, and children, until one of the night patrol noticed and set off the alarm would be quite boring. Wouldn't it."

"But would you like to know something even better?" It asked lowering itself down to my ear,and whispering. "You're the last one alive... and I'm feeling rather peckish." And before I knew what was happening he reared up and brought his fore hooves down on my skull.
