Celestia would later awaken from a most refreshing deep sleep to find that her sister kept her promise. The sun was at rest in it's proper place and Luna's beautiful pale moon illuminated the night with it's ghostly light.

"You're awake... that's good. I do hope you're feeling refreshed enough to head out," spoke a soothing familiar voice whom she didn't have to second guess. Apparently Luna had walked in without even a knock.

"A little excited, but that's nothing I can control," Celestia replied as she turned to meet her sister. Their eyes met, big goofy smiles across both their muzzles. "So, was that just a one time thing?," Celestia asked, breaking the quietness.

"My sanguinary penchant can never quite be satisfied. Then again, I'd like to avoid rushing you to the royal infirmary for a blood transfusion. Then there'll be the rumors. The guards will suspect I might have resumed my plans to take over the kingdom, just without the appearance of Nightmare Moon," Luna laid out a myriad explanations, but none of them a clear answer.

"Yes," Celestia interrupted her sister with a hoof to her muzzle, "Or no," she added as her hoof pulled away.

Luna took a long deep breath and exhaled it through her nostrils in thought as she eyed her sister, "Somepony might think I've turned you into a bloodletter, Tia."

Celestia canted her head, the subtle hint of a sly grin twisted across her muzzle,"And what if you have?," the white alicorn queried as she moved toward the side of her bed. From beneath one of her many pillows, she whipped out the scabbard of a rather short blade with a golden pommel, black handle and silvery cross guard. With it wrapped within the golden glow of her magic, Celestia unsheathed the blade slowly. Her eyes remained fixated on her sister though and she could see a faint craving gleam in those bluish eyes as they flickered teal for a second.

"Celestia, please," begged the Princess of the Night as she stepped closer. It wasn't a plea to stop though, it was one filled with the pang of desire as she watched Celestia levitate the small blade down to an extended foreleg. The finely sharpened edge sliced through the thin flesh with little effort as Celestia's magic guided it. Her irises expanded as she saw a trail of her sister's blood run down her foreleg.

Like a starving beast who had happen upon a carcass still fresh, Luna was soon cradling her sister's foreleg while her tongue hungrily lapped up the scarlet nectar.

Celestia sighed in bliss, watching as her sister fed on her blood as it continued to spill out of the self-inflicted cut, "Yes, drink to your heart's content, sister." Celestia's nether regions were damp by the time Luna was satisfied with her meal.

A little bit later after a restorative elixir...

Luna and Celestia were sailing effortlessly side by side through the dark midnight sky. Under the cover of darkness, only a few Royal Guards noticed the all too familiar silhouettes heading down toward Canterlot.

"Stay close, Tia," Luna was quick to say when they landed in what seemed to be a small, but seedy part of Canterlot. There were plenty of derelict buildings who now only played host to what few undesirables that called the royal city their home. They swept through several small alleyways until finally Luna and Celestia arrived at their destination. A plot of land that was just that. An empty plot of dirt.

"Well... this is exciting," Celestia mouthed, eyeballing her sister with a bit of suspicion.

The dark blue alicorn hushed her sister, "Quiet... and wait right here," then proceeded to move toward what she could only see was a rather large vacant lot.

Celestia raised an eyebrow and then watched as her sister moved ahead of her, "Of course, if you insist." The solar princess was beginning to wonder what sort of trickery her sister was planning. So far, it wasn't very exciting. Her eyes moved to the freshly mended cut on her foreleg. Celestia then watched as a mute witness to the sight of her sister now apparently talking to thin air. There were words exchanged, but she could only barely make parts of what appeared to be a one sided conversation.

Luna soon returned, looking quite pleased as she nuzzled into her sister's neck. The white alicorn immediately returned her affection. "Okay, you can come in, but you'll have to know the rules first," Luna whispered into her sister's ear.

"Come in, where?," Celestia asked. She could see nothing. She couldn't even sense anything. Far as the princess could tell, it was just empty.

"It's the best night club that doesn't exist, Queen of Hearts," Luna went on to reveal. She pointed a hoof toward the vacant land. "It's there, but that doesn't matter. There are some very strict rules for the patrons."

Celestia perked her ears up. She was very puzzled, but this talk of a secret night club that apparently doesn't exist was at least more amusing than the vacant lot. "Rules?," Celestia probed.

Luna nodded, then took a deep breath. This was going to take a bit of explaining. "First rule, never refer to a pony or anyone else by their real name. It's the most important. We all have nicknames."

Celestia slowly nodded, taking in the information, but it only made things a bit more muddled. "Okay, nicknames. Though, why?," Celestia quickly asked.

Luna giggled before explaining much to Celestia's delight, "Let me put it like this," she moved a hoof toward what was apparently an invisible night club, "In there, everypony goes by a new identity that has no connection to the outside world. I'm not Princess Luna, I'm just Lulu. Nopony is allowed to acknowledge the fact that I'm the Princess of the Night."

Celestia just seemed bewildered, rubbing her head as though all this was just making her have a headache, "Okay... so then do I know you or do I not know you when we're inside?"

"You'll know me as Lulu, and for your nickname, you'll go by Tia," Luna explained.

Celestia again, slowly nodded in acknowledgement, "So I'm Tia, you're Lulu and we're not sisters, right?"

Princess Luna's head bobbed up and down repeatedly in approval, "Yes, we're just friends as far as anyone else is concerned."

"Why though?," Celestia asked, still not quite sure why such a secretive invisible night club had to use such complicated rules.

"You'll find that out soon enough, just stay close and I'll introduce you," Luna embraced her sister in a hug, her teeth grazing the supple warm flesh of her neck as she nibbled playfully. "It'll be fun, trust me."

Celestia eagerly embraced her sister back then whined as she proceeded to tease her with a few playful bites along her neck. "I trust you, but this best be something spectacular for all the trouble we're going through to get inside."

As the two sisters came closer, Princess Luna's horn ignited with an aura of her blue magic. Once the specially crafted spell was cast, a large three story building composed of bleached marble with large stain glass windows seemed to slowly shimmer into existence. It absolutely towered over the rest of the run down shanties. On the front, a magically powered red neon sign buzzed with life, advertising the name which Luna had mentioned earlier, "Queen of Hearts."

Celestia gasped in amazement, mostly because she had never even known of this building's existence nor that something could be hidden from her view. She could hear voices inside and booming vibrations of music extremely heavy in bass.

Luna nodded her head forward, eyeing her sister with a rather inviting smile and heavily lidded eyes that were definitely of the provocative nature.

They both wandered up to the large red double doors that swung open as if all too eager to have their presence. Vibrations of bass could be felt through their bodies as they walked in side by side. A cacophony of ponies' voices screaming and hollering were nearly as loud as the music. As they disappeared inside, the doors slammed shut and the building faded back into nothingness.
