During what started as a perfectly fine Lunch, Twilight learns that her friends have somehow gotten it into their heads that she is in a relationship with her mentor and idol Princess Celestia.

Twilight is confused when she receives an invitation to a party that seems to assume she has a plus one already. Celestia is confused that Twilight is confused. They are dating, right?

This is the story of the end. This is the story of the death of Equestria.

Twilight Sparkle has been living a lie. Everypony told her what a beautiful and accomplished mare she was. Everypony thought she was a responsible adult. They were wrong. She was still just a filly trying to stumble her way through life.

One night a year, on the Eve of the Summer Sun Celebration, Princess Celestia is sad, at least according to Twilight's observations. She has a plan, a boardgame, and is determined to try to cheer up her mentor.

Shining Armor has been infected by a Changeling poison that threatens to destroy his magic or worse. When Twilight and her family are tested to see if they could be potential horn marrow donors, an old family secret is brought to life.

Everyone is dead. She doesn't know who is responsible, just that somepony activated the ultimate weapon. Only four ponies survived and now try to find meaning in the great wasteland. Celestia will just be happy if she can find a way to heal Twilight.

After an innocent conversation, Shining Armor is feeling uneasy about his wife’s special talent and even more worried about something he learns regarding Princess Celestia. Luckily for him his sister is one of the most talented ponies in Equestria.
