A long time ago, two sisters ruled over the land: one held dominion over the day, and the other commanded the night. They quarreled, and to solve their dispute, they did something petty. They split the planet in half. They stopped the rotation of the planet—tidally locked it—so that one side would always be night, and the other always day.

Rarity is a member of the Corona Empire's parliament, sworn to do what is best for her country. One day, Queen Celestia summons her for a private talk. She asks Rarity to do something unthinkable, unfathomable, unheard of: deliver a message to the leader of the Nightscape, Queen Luna.

Princess Twilight Sparkle writes letters to her former mentor.
Her friend, Spike, would rather she didn't.

A 'Know your Star' story; only with your favourite ponies getting unneeded hassle and lies told about them. Won't this be fun? Probably not... But hey, everything can't be seriousness all the time, so let's take a load off and just pester some ponies, and Spike for good measure.

The never ending adventures of Know Your Mare march on and on and on.

Rarity discovers an old tradition involving the exchange of felt dolls as a sign of affection. This sparks a brilliant plan to play matchmaker with her friends, and between herself and Twilight.

But brilliant plans never go as expected, do they?
