With nothing happening, no world-conquering villains or Crystal Hearts being shattered and so on, Twilight is bored. She has nothing to do, plainly. But while in the middle of a drab reading session, she notices something doesn't feel right. Not to her, but in the night sky. She can't see it, but she can sense it. Something not from this world has entered her world, and it could be the first ever message from aliens.
And perhaps those aliens are trying to say hello.
(Btw, look up "Pioneer Probe Plaque" if you want the image described here. I can't post the actual thing because of mild nudity in it, but you can search it for context.)
