So this was decided late one delirious night when a friend and I were super late getting home from a convention. I swear to God we were acting like we were drunk and we hadn't even had a single drink… so this is like an exhausted induced pairing that I ended up shipping soooo…

She flicked her pony ears. There were no noises in the quiet Palace of the Two Sisters. No one, save Twilight Sparkle, came here anymore. But she, on nights when the ponies nightmares were few and far between, rare that they may be, she would visit her old home. Her dark wings rustled against her side. Her brilliant moon gleamed brightly down on her through the broken ceiling.

Luna closed her eyes, feeling the dancing moonbeams on her face. Even after a thousand years of being captured in the moon, nothing felt better than her beautiful moonlight. She felt her wings spread of their own violation and lift her through the hole in the roof and into the gentle moonlight.

After basking a bit longer in the gentle glow she angled down to the Tree of Harmony. This beautiful crystalline tree may have bestowed a castle on Twilight Sparkle as Princess of Friendship, and Luna would be the first to attest to how special the young Alicorn was the Tree seemed to be trying to speak to Luna, and as far as she knew, she was the only one it had attempted to speak to.

She just couldn't hit the right resonance of magic to hear the great magical Tree yet. Her blue clad hooves gently touched the ground and she strode forward, head held high, horn glowing as she searched for a spell.

Before she could find one, however, she sensed something she knew all too well. Darkness. Her ears slammed back on her head and her spell changed.

"Who is there? Be forewarned, this is a sacred place in a peaceful land and a Princess of the Night, I shan't allow you to bring evil upon it!" Luna warned raising her wings to appear more threatening. A dark figure snaked around the Tree of Harmony.

"Hello, little princess," hissed a dragon of ancient times. Luna hadn't seen a dragon of this species in thousands of years. He was wingless with a long serpentine body. Spiked horns jutted from a black mane and reptilian eyes had locked onto her. Whiskers danced around a muzzle of razor sharp teeth.

"What business have you in Equestria?" she demanded. "Depart from the Tree of Harmony lest I be required to use force."

The dragon chuckled and rested his great bulk at the tree's roots, long claw tapping the bejeweled earth beneath him. "I come to you, alicorn, because you are darkness, like myself, and your magic is equal to mine."

"Mine power is not for you to exploit. I am a princess in these lands and have no interest in aiding you, your conquests," Luna argued. The dragon shook his head, chuckling low and dark. Luna didn't like the sound of it. Her pinfeathers stood on end and visions of Nightmare Moon flashed in her mind.

"Little Princess of the Night," he said, somehow making it mocking, "Yet you abhor the darkness within yourself?"

"I know not of what you speak," she responded.

"You deny the truth to me as you do yourself. I see the darkness within you," he growled low, lowering his muzzle to her.

Luna's heat was pounding. Her instincts, ancient and buried, were screaming in her ears, yet duty demanded she protect her home. She would do just that.

Look to the Tree to keep the Harmony. Her eyes darted to the Tree. The moon on the trunk was glowing. Luna knew what she must do. She leapt into the air with a mighty push of her wings and sent her spell to crash into the mark on the Tree that matched the one adorning her flank.

Magic erupted from the Tree. Dark tendrils wrapping around the dragon and pulling him into a portal, but not before he grabbed Luna's back hoof dragging her into some unknown world with him, far from Equestria.

Now the reason this is so short is because it is merely the prologue. The chapters will be varying in length but I can promise chapter one is indeed longer than this. R&R! :D
