Equestrian Mythology and some other stuff too
It all began when The goddess Lady Faust took a magic pen and made a big,bright,beautiful world called Equestria. She created two divine beings called Alicorns to raise the Sun and Moon. A stallion named Terra and a mare named Aeterna. To keep the land from getting to serious, she made two bizarre creatures named Draconequus One was Entropy, the other Eris. And because every good story needs a good villian, Lady Faust produced a Sharpie and created Changelings. Then she created Earth ponies, something for the Alicorns to rule over, the Draconequus' to entertain, and the Changelings to lust after.
The Draconequus' requested unusual power, so Lady Faust gifted them with the power of Chaos.She then rested for now her work was complete.
Now Earth ponies were strange creatures afraid of the unknown. So naturally they chased Entropy and Eris into the forests, where they could perform Chaos without being chased away.
The years went by and as Equestria grew older, an amazing thing happened. Love. The Alicorns fell in love and couldn't escape it's hold. They were married and produced a foal named Celestia. The Draconequus' loved each other from the start. They had a child named Discord, after their own lack of harmony. The Queen of the Changelings, Alteratia, gave birth to a special offspring which she raised as her own. The father was Metamorphosis, who kept watch of their home in a beautiful mountain.
The creatures all raised their children differently, Celestia was led to believe she was destined for greatness, Discord was to live the life of an outcast, The young Changeling Chrysalis was to lead an army to battle Equstria. They were each treated differently, Discord led a life of ease and recklessness. Celestia was convinced everyone had high expectations for her. Chrysalis lived a cold and cruel childhood.
These creatures each had a destiny that would change Equestria, they just didn't realize it yet.
