Princess Pinkie

And that is how friendship disappeared from Equestria. Pinkie Pie had finally gotten the upper hand against Twilight Sparkle.

It was a raw, crude laughter that rang out from within the supercomputers. A hollow laughter. A sarcastic laughter, heavy with despair. A laughter that rang only to fill a void, because there was nothing left except laughter, and nothing to laugh at but the emptiness.

And yet, it was not quite alone, for there was another laughter, louder than the first.

It rang malevolent up from beneath the ground, and shook the jungles that had overtaken the surface of the planet, and frightened the birds into their nests and the beasts into their caves.

The stars cried and hid their faces, and the sun covered his head in ash, and the waters put on their mourning black, and the wind kept silent for shame.

The laughter rang out across the universe, clear as a church bell, straight from the lowest circle of Hell.
