Written back during season one, this is yet another origin story about how the sisters fell out a thousand years before the series began.

AU. Based on the first season. Twilight and Celestia begin to drift apart due to a misunderstanding. Will Luna speak up and repair the breach, or will she remain silent to keep her new friend, Twilight, all to herself? What other challenges will face everypony involved because of this new relationship?

It's a simple little love story. Unfortunately, love's not simple.

Based off this sketch I drew at work and the resulting skype conversation.

Princess Celestia invites Twilight Sparkle to join her on the roof for sunbathing. The two share a tender moment together building a greater friendship together and moving towards more...

Luna is on a mission and she will not rest until her mission is completed. Her objective?

To snuggle with her big sister.

Twilight is a princess, and traveling the land to meet ponies far and wide; an excellent opportunity to make more friends. So why is she so unhappy?

Many years after sending her beloved protege to Ponyville, unease sits heavily on Princess Celestia's heart as her relationship with Twilight Sparkle seems to have cooled despite all they've accomplished together. On the advice of her sister, Celestia sets out to investigate and resolve the lost connection with her most faithful student. What does it mean to be a Faithful Student...or a Princess of the Sun?

Earned a six-star rating on Equestria Daily and featured on its very own TVTropes page!.

Luna is back from the moon.

And she is pissed.

...No, not at Celestia. Those drapes don't match the windows. The furniture doesn't match the carpet. Seems that aesthetic knowledge has declined since she left; good thing Princess Luna is here to save the day with her interior design skills!

The two ponies I care for the most, my dear sister and most faithful student, have betrayed me. My most loyal guard says I'm just being paranoid, but what would he know that I don't also? I thought the nightmare was over, but now it's clear it never went away. In fact, it's only gotten stronger and more cunning, as evidenced by how it's turning all that I hold dear against me. Well, it won't succeed, and I'll do whatever it takes to make sure of that. Mark. My. Words.

Do you remember being born? Torn away from everything that is familiar and cast out into the unknown?

I do.

It haunts my dreams.

It's Luna's first winter back home, and her work is weighing her down. She goes flying to clear her mind, but soon she wonders if anything has changed at all after her time on the moon. Soon she has to face her hatred in the form of windigos, but she doesn't know how to stop her own hatred. Can she find the solution in her dreams?
