It was a normal night. The crickets were chirping, the frogs were singing. Luna's moon shone down upon all Equestria. If it were not for the pegasi swooping down from the clouds, it might have been too normal.
As they descended, each one tapped a button on the device on their foreleg, and vanished. Then, 3 figures reappear next to a house. One of them picks the lock, and opens the door and all 3 go inside. The sound of a quick scuffle comes from the house, then silence. The 3 figures re-emerge now carrying a black bag and close the door back. Then all 3 prepare to take off, and vanish. The last that is seen of them is 3 black dots fading into the clouds.
Celestia watched this, knowing full well what had happened, yet did nothing. And even though she felt horrible about it, one does not simply go back on what they allowed happen in the first place.
