Twilight Sparkle: One thousand years ago, Equestria was on the verge of a
great discovery. When the scientists and unicorns invented a
new art that allowed everypony to use magic, regardless of race: the art of magic and science that is called alchemy. Though it was a slow process.
Cadence: The pony alchemists have created a new energy source that benefits the whole world. Creating new forms of transportation, clean energy, and most of all, space exploration. We first traveled to the moon, and discovered a whole race of bat ponies. They taught us how to use alchemy. Those of us who gained the ability to use this new kind of magic, we called Warlocks.
Now, we travel through space, from planet to planet, discovering new planets that were habitable like Mars, and created colonies on the moons of various planets. It was an golden age in Equestria. But years later everything changed.
Nebula: When the explorers set off to the stars beyond, an entity corrupted the minds of the griffins and minotaurs. This was the first time we discovered the Darkness. The griffins and minotaurs rebelled against us, and somewhere within the swamps of Equestria, the changelings gained a new-found power. We have been fighting for two centuries, trying to defend our home from the minotaurs, the griffins, and the changelings. Then, in the final days of the war, Princess Celestia and Princess Luna made the ultimate sacrifice.
They gave up their lives, and in the process created a new celestial object - a second moon. Nopony knows what it is meant for, but somehow, it keeps the Darkness at bay. But we don’t know how long it will last…
Twilight Sparkle: Now, after many years at war, Nebula, Cadence, and I have founded a new group of warriors who will help us in our time of need, and destroy what is left of the Darkness, as well as our common foes.
