The year is twenty-fifteen. Equestria was a bright and peaceful place. It had been a little over a year since the mare in the moon was defeated by the elements and returned Luna back to her self, cleansing herself of the nightmare. Everything was perfect all around Equestria, or so they thought. Little did they know, a dark spirit of chaos was breaking out of his stone prison of a thousand years. Discord, the spirit of chaos would walk among them once more. Even Celestia, the wise princess of Equestria wouldn't be prepared for what was about to happen.
Discord had broke free and his first act after being free? Kill the princesses that imprisoned him. He succeeded into killing Celestia but before he was able to kill Luna, she managed to escape, fleeing to Ponyville to warn the element bearers. Discord soon took his throne over Canterlot, plunging the once shining jewel of Equestria into total chaos and a shadow of its former self. Luna had warned the elements and they proceeded into heading to Canterlot to stop Discord. Once they arrived, Rainbow Dash did the same thing she did with that dragon that was sleeping in the mountains outside ponyville. She rushed up to buck him in the face, however it didn't go as it did then. Discord killed her before she could bat an eye. The elements and Luna were stunned at this. Without one of the element bearers, they couldn't imprison the evil spirit again. So, they did the only thing they could. They fled.
Twenty years have passed since that day. The year was twenty-thirty-five. Equestria now lay in ruin. A barren wasteland. A mere shell of it's former glory. Over the years, a new force had amassed, forming to take down Discord's tyranny. The name of this rebel force was the Ironhoofs and Twilight Sparkle had taken on the role of General of this force. Over the years, things have changed drastically. Weapons were invented to help fight back the dark god's army. Guns, explosives, even swords unlike anything that's ever been seen before. And over the years, Twilight's magic had weakened considerably thanks to the raw, untamed chaos magic that now blanketed the land. Twilight had also lost her right eye to the chaos of war, so she wears an eye patch to cover it.
A year before the war began, Rarity and Twilight had grown close and soon married. They loved one another greatly but when the war began, everything changed. Twilight began to grow weak, until finally, on their nineteenth anniversary, Rarity was cut down by a chaos beast protecting Twilight. Rarity was just below Twilight in ranks of the rebels, Twilight's right hoof in a way. Applejack had soon risen to that station soon after Rarity's death. Rainbow Dash had been killed the same day Celestia was killed, due to her recklessness. She thought she'd buck him like she did that dragon in the mountains. Pinkie Pie had also been cut down on the fifteenth year of the war. She was protecting a foal from one of the chaos beasts but was powerless against it. In this twenty year war, only three of the elements remained. Magic, Honesty, and Kindness.
One day, twenty years later, Twilight decides to go back to the past and try to prevent Discord from taking over and laying waste to everything she ever held dear. So, she comes up with a time traveling devise that fit on her forehoof. So, now Twilight Sparkle was in the past, hopping to prevent her horrible future from ever taking root. She needed to gather the elements, the princesses and any other who wanted to help take Discord down but it wasn't going to be that easy for her. One wrong move and she sets the war off herself and that's something she did not want to do.
