Almost ten thousand years ago, superstition and the sword ruled, it was an age of darkness, it was a world of fear. It was the first Storied Age, the Age of Heroes. Humanity was ruled by the mighty wizardkind, who were seen as gods in the skins of men. Then came the War of Wizards, wizard fought wizard, brother turned upon brother, sister slayed sister. They're destructive powers raging across the Earth, destroying everything in their path. In the end, they lost. They lost, everyone lost. Everyone but the Five. Four wizards and a witch, last of their kind, lived on. Surrendering their rulership of mankind, they vanished, seemingly forever, leaving nothing but ash,death, and the Great Seal, a massive runic seal that help all the world's magic at bay.
~2020 A.D.~
A massive unknown landmass appeared in the Atlantic Ocean. Humanity responded by sending planes and ships to investigate, only to find their machines to suddenly stop working, causing their planes to fall, killing them on impact. The boats however, managed to get much closer. They were meet with an invisible barrier. There was no penetrating it. It stopped everything, bullets, bombs, fire, grenades, knives. Everything. About a month later, however, a pony by the name of Princess Celestia appeared on an international new show reporting on what the reporters were calling "The Silent Invasion"(what can I say, reporters are weird). She explained that the barrier what due to our world and her's completing a cosmic shift that had begun ages upon ages before. Unfortunately, she said, our world was devoid of magic, and thus, instead of a portal between the worlds, the barrier had formed, impregnable to non-magical objects and beings. She also said that she and her subjects had created a serum that would transform a human being into a pony, thus allowing them to pass through the barrier. She asked the United Nations(and pretty much everyone else) for permission to set up what she called "Conversion Bureaus", to hand out the potion to those that wanted it. After three days of negotiating, the United Nations(and almost pretty much everyone else) decided to allow these buildings to be constructed. Almost five mouths passed as the Bureaus were built. When they were finished, they opened their doors. The broke, in debt, and many of the homeless flocked to the Bureaus for the serum. Thousands were converted within a month. It was during that time that The HLF(Human Liberation Front) and the PER(Ponyification Earth's Rebirth) terrorist groups were created. Five years passed, and a little more than three billion were converted, both by choice and by force. That's when people began realizing something was wrong.
The 'newfoals' ,as the ponies called them, boar little trace of their previous personalities, and seemed repulsed by the mere sight of a human. Conversion slowed to a trickle, and the HLF gained more and more support. That's when it happened. The barrier began to expand. This caused massive uproar among the remaining humans. Celestia claimed that the barrier was expanding naturally, and that all humans must convert or die from it. That's when it happened. The HLF bombed several Conversion Bureaus, killing approximately 2,000 ponies, 9,000 humans, and 1,000 newfoals. Then Celestia responded. She declared, on April 7, 2027, that conversion was now mandatory. Naturally, humanity was astounded. They fought back, killing ponies on sight. However, in the mist of the conversions,mankind had failed to keep an eye on it's creations. They were failing, the more modern and complicated the faster. Humanity's precious technology was failing, dying, not working. World wide. In 2028, the barrier's westward progress, stopped. Just, stopped. In the middle of the Atlantic, it just stopped. And it's Eastern progress split when it hit Ireland. It was like someone had pressed a small metal ball through a lump of clay. It kept advancing, but there was a pair of lumps in it.
By 2030, humankind was forced to resort to their most desperate weapons. Their electricity impossible, their bullets and bombs exhausted. Bows, arrows, swords, shields, and spears. The most ancient weapons they had. The humans numbered only a billions now, while the ponies numbered nine billion. Humanity knew it was fighting a losing battle, but they still fought on. Then, an old pagan habit resurrected one very dangerous miracle: the rune stones. Small glowing rocks engraved with mystical runes, granting the user powers unlike any seen in more than three-thousand years. It was old magic. And it had given mankind a chance.
