Twilight is on the cusp of leading Equestria for a year. It's been an easy year with no major difficulties. No wars. No natural disasters. No villains.

At least until a villain from the far, far future appears in Twilight's throne room. She's escaping defeat at Twilight's hooves, with one thought in mind: she won't be stopped if Twilight doesn't exist in the future. And here's Twilight's past self, right in front of her. Easy.

Unfortunately, she's not the only villain with this idea.

Motherhood is hard, as Shining Armor knows, and Cadance has been dealing with a lot lately. So, when Shining comes home, he's not too surprised that she seems a little... off. But it doesn't take long before he realizes something is not quite right. In fact, there might be something weird in the very foundation of their family...

Warning: Is a lot more harmless than the title and description might lead you to believe...

All Sweetie Belle wanted was one pony to show up to her audition. Just one. And what with everypony else so busy, she was thrilled to know that Rarity would be there for her...

...but she didn't show. It was an empty theater.
