When twilight discovers something which shouldn't be possible, a changeling in celestia's castle, she does some digging and finds a top secret agency. (set after whichever episode introduced pinkie's party cave)

(is told in a script style but still story telling style when you see these ().)

(I do not own any charecters in this story)
(rated t as men in black is not a kids movie and one or two shipping jokes)
