Two years have passed since the Dark Eldar ravaged Equestria and its neighbors. Aries has used this time wisely and trained a Planetary Defense Force numbering over 2,000 strong...but few dare to consider themselves safe.

Fluttershy and Greenskin juggle nursing Cozy Glow back to health with training the Squigs and Snotlings that have begun to spawn within the kind Pegasus' Sanctuary.

Through it all, Pinkie Pie has laughed and smiled and encouraged others to the same...but she knows better.

The Party Pony's Pinkie Sense has made it known to her: an evil beyond reality is stirring, Equestria shall be it's next target, and before the war is won, a tragic comedy shall play out before her eyes and make her the butt of a cruel joke.

But what she doesn't know...is that the Element of Laughter has chosen its successor, and he is a professional at Dark Humor.
