For years, Luna has endured the guilt of Nightmare Moon and subjected herself to the nightmares of the Tantabus as punishment. When she lost control of it, her friends in Ponyville were able to stop it and things seemed all right for a time...

...but what about Celestia? What about Luna's closest friend, a pony who had no idea what was going on in her little sister's mind?

"My dear Twilight Sparkle,

Thank you for your recent letters. And I must apologize to you first and foremost that I have not responded back in kind to each and every one. I imagine has this concerned you, but please don't worry. Things have been very unsettled here in the castle as of late. Princess Luna has been researching Equestrian history, and I find myself in a strange kind of mood..."

When Rainbow Dash approaches the Princess of Friendship with a question about friendship, Twilight Sparkle is delighted to help her friend, even if that friend is being uncharacteristically coy about some of the actual details of the question. As she digs for the right answers, the question continues to become more complicated.

Then things get awkward.

Luna has never thought she really deserved her subjects' or her sister's forgiveness. Often, she questioned it, though she kept these thoughts to herself. When the pain of her past and her guilt continually eat away at her, she feels she deserves the pain, but she can only live with it for so long. Luna doesn't believe she should be in Equestria, let alone remain a princess. However, somepony else thinks very differently. If only Luna could see what she sees.

Sometimes a crash that destroys can create so much more.

Wings. A title. Responsibilities. A relationship with Luna.

Twilight Sparkle has gotten used to a lot of things since becoming a princess. But there is still more out there for her to learn. Most especially in regards to her marefriend.

Twilight ventures out into the mountains to see a once-in-a-lifetime event. Disappointed by her friends not coming with her, Twilight crosses paths with a kindred spirit.

[Complete! With TVTropes apparently!]
Also, apparently, an animated trailer.

In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

For Twilight, her relationship with Rainbow Dash couldn't be better. She can't help but be happy whenever they're together, and the usually abrasive pegasus has shown her softer side. Recently, however, Twilight's started to notice that there's something on Rainbow's mind. Something bothering her about their relationship, and Twilight's determined to find out what it is. The answer she gets might just confuse her more.

After all, when it comes to something as subjective as emotions, there's no handy reference guide to tell you how you're feeling.

Twilight has always loved mysteries. Researching them, dissecting them, and finally, solving them. Almost nothing could compare to the joy she feels when finding an answer to a question no pony knew.

But there are mysteries with answers better left unheard, truths that aren't meant to be known. Now Twilight has solved a mystery with an answer she doesn't want, an answer she can never forget.
