Princess Luna has always been the worse half of the royals and everypony knows it... She was, and somewhat still is, the devil that's known as Nightmare Moon... She does not wish to confess this horrid truth, for it haunts her continuously. And with being alive for who knows how long, it seems as if the oddest thing in the world has happened to her... Somepony has chosen to love and cherish her... They adore her nightly beauty and how mysterious she is... But, this love of hers is dangerous; she will cause harm... it is but an inevitable truth...

Twilight prepares for the most important night of her life. But it doens't go exactly as she had wanted...

Story was inspired by SolFoe's Study Interruption

It's the day of Hearth's Warming Eve. Twilight is preparing for the holiday when a surprise guest comes to her house. It turns out to be Princess Luna and she wants to spend Hearth's Warming Eve with Twilight and her friends. Twilight accepts and the two decide to have a slumber party! Little do the two of them know that a deep secret that both of them had will be revealed to each other. Will the secret bring them closer or tear them apart?

Redemption is rarely the end of the story. Princess Luna was given another chance, saved from an eternity of darkness by a lone unicorn. Without Twilight Sparkle, the world will tremble before the mare who rocked the world with her betrayal in days long past.

It's date night for Twilight and Luna, and they're both enthusiastic in their planning and preparations. Unfortunately, Celestia and Rarity both find out, and confessions are in order...

***************

Yes, I know the title is an obvious and shameless joke and I should feel bad. You come up with a better title.

Princess Luna finds more than a friend in her sister's student, and Twilight Sparkle gets a chance to study the moon and stars far closer than she ever dreamed possible.

An ongoing series of slice-of-life snapshots. Expect a castle's worth of clop-free d'aaawww.

These stories are in continuity with The Rustic & The Romantic and If the Flight Suit Fits.

Now featuring cover art by the inimitable Cerraka (formerly xaztein / crenair)!

All the World’s a Stage - Luna had a wonderful evening with Twilight and sang her heart out about it. Oh, and she might have left the door open.

Early Observances - If you're going to interrupt Celestia's sleep, you'd better have a very good reason.

However, after just one night together that is no longer true and together the two of them embark on journey of secrets, lies, trials, friendship, and true love.
