Six years ago, criminals started spreading rumors of a monster prowling the streets of Gotham City. Strangely it only hunted criminals. It sounded foolish at the time, but they said it looked like a bat.

Three years ago, Tirek won. He effortlessly crushed the princesses and took the power of the princesses for himself. He had won. He should have won. It it happened a few years prior he would have won. But he didn't. He was defeated by a mysterious woman of power. She called herself "Shazam.

A "Wonder Woman" was found associating with Shazam. A red blur was spotted stopping crimes in Cloudsdale. A mermaid with legs killed a group of slave traffickers in the Atlantic. It was all rumor and mystery. Until it wasn't. An alien invasion of Appleloosa was prevented by a squad of aliens with green auras and constructs. Afterwards, locals noticed that there was a woman among them. She called herself "Green Lantern"

Suddenly everything shattered. The rumors were all real, a planetwide invasion force was defeated by a group of metahumans who called themselves the "Justice League". The world was never the same again.

All these are the reflection of Princess Twilight, who is to become the ruler of Equestria and be imbued with the power of the sun.

Three years ago the Age of Heroes began.
