Twilight brings Starlight Glimmer to the library of her castle, where the magic mirror to the Human World is located. Twilight has come up with an interesting theory: the existence of alternate worlds. She hopes to accomplish this task with Starlight as witness. Little does she know, they may witness more than they bargained for...

Twilight REALLY needs to stop messing around with that mirror ^;

This is something I've been wanting to make for a while.

The multiverse is an interesting concept. How the world would be like if one unexpected event changed the course of history ^{^} But as much fun it is to imagine about these places, we probably would not want to live in any of them. As dark as destiny has become for most of these MLP universes, one can only hope that there is a glimmer of hope, light and salvation at the end of that dark, dark tunnel.

Either within the universe itself. Or from the mirror...

Note: In case anyone is wondering, Twilight and Starlight's mirror is connected to a similar mirror in the alternate realities. And since the mirror is usually in the possession of Celestia, each one is located in the Canterlot Castle throne room. In the Nightmare Moon reality, it is in her castle (formerly the Castle of the Two Sisters) as a trophy.

In Discord's universe, he has re-arranged the structure of Canterlot castle. So the mirror is still there. But it probably looks different now...
