A Hollow in Rainbow Sand

Location: Canterlot Castle/PoV: Jack

It's been about a month since Luna returned to Equestria and agreed to be my marefriend. We knew each other well before I confessed, but I still wanted to take things slow. Unfortunately, that didn't happen.

Flashback: One Week Ago

I stood guard over Luna as she 'slept'. She wasn't really sleeping, instead patrolling the dream realm. The sun was about to come up, so she would probably finish up pretty soon.

As if she could hear my thoughts, her eyes snapped open. Just I was about to ask how it went, she grabbed my arm and flipped me onto the bed on my back. Straddling me, her horn flashed with magic as the walls, windows, and door all glowed as well.

I opened my mouth to ask what she was doing, only for her to kiss me rather ferociously.

"I'm sorry Jack, but I can't hold back anymore!" Luna exclaimed as she pulled back.

"Luna what the heck?!? I thought we were going to take this slow?!?" I said in shock as I tried to get up, only for her horn to glow again before my arms were tied to the headboard. Panicking, I tried to turn into sand only to have nothing happen.

"I've waited over a thousand years Jack, and with estrus cycles happening every year, it builds up. I was willing to wait a little longer, but one of the dreams I saw featured you. You and another mare, doing things that brought back those feelings. I want you to do to me what your dream self did to that mare!"

Flashback Over

It only took her a few minutes from there to...*Ahem* persuade me. We didn't leave the room until it was time for Luna to raise the moon. Even then, she dragged me back afterwards!

The next morning we walked into breakfast with a distinct limp. Celestia had smirked at us for only a moment before looking at me with a serious face. The conversation I had with her at that moment took an unexpected turn.

Flashback: 6 Days Ago

"I hope you realize what will happen if you break my sister's heart, Jack." Celestia said.

"Oh trust me, I'm more than aware." I replied as I sat down and summoned a bottle of painkillers with the kaleidoscope. I would have gotten some for Luna too, but I wasn't sure if human medicine would be safe for ponies or any other race from Equus to take. Luckily it seems that she was far ahead of me and was already taking some medicine she had requested a nearby servant to get for her.

Then I turned to Celestia with a glare of my own, "Just like I hope you realize what'll happen if you or any other mare gets between us."

To my surprise, she looked genuinely confused. Then she said something that shocked me to my core.

"Why would you not want another mare in your herd?"

My shout of "WHAAAAAT?!?!?" was heard throughout all of Canterlot.

Flashback Over

It took Luna kissing me again to calm me down. Apparently there was something 'lost in translation' in a sense.

It turns out that the gender ratio in Equus was skewed 10:1 towards females. Because of this, harems (or rather HERDS) were legal. Luna and Celestia seemed shocked when I explained that humans normally married one person and stayed with them their whole lives. They were even more shocked when I mention that humans had no genetic bias towards one gender or the other.

Anyway, after breakfast Luna dragged me back to her room. Though this time, rather than engaging in more explicit activities (Thank goodness!) she wanted to have a serious discussion with me about rules for if I did want a herd.

When I explained that I would be more than willing to only have her, Luna shook her head and muttered something about me being too noble for my own good. She then explained to me that she wanted me to have a herd, but that she would have to approve of any other mares I brought in.

Right now, however, I had more important things on my mind. Such as the fact that an entire squad of the night guard were now in the medical wing with severe magical exhaustion and a few physical injuries. Due to magical exhaustion they would be unconscious for at least a month. Now this would be cause for concern on its own, but this was the fifth squad this week. Whatever is doing this is scarily efficient, and only struck at night. Even doubling the squads per patrol route after the first attack did nothing to impede it.

Luna, Celestia, and the captains of both the day and night guard (A unicorn named Shining Armor, and a bat-pony named Shadowed Blade respectively) were attempting to help me figure out what to do.

"Something has to be done!" Shadowed Blade exclaimed as he slammed his fist to the table, "My men are getting completely torn to pieces by whatever this thing is!"

"Calm down Captain Blade." Luna said with a minor glare, "I understand that you're worried for your soldiers, but getting angry will do nothing. If we are going to get this right, then we must keep control of our emotions."

As he hung his head, Shining Armor put a consoling hand on his shoulder. Apparently the two saw each other as brothers in all but blood due to the amount of joint missions together.

"Princess Luna is right Blade." Shining said, "I would feel the same way if my men were attacked like this."

Turning to Celestia, he offered to have the day guard join in on the night patrols.

"While it may work Captain Armor, your men need their rest. The lack of sleep would only hinder them." She replied.

We descended into a ponderous silence for a few moments before an idea occurred to me.

"Everyone, you are aware that I can reform my body from any point with enough sand, correct?" I asked. They nodded, "Well what if we have all of the remaining night squads carry a sandbag with them at all times? If they are attacked, then they will dump the contents of their bag, allowing me to appear at their location to at least try and hold off whatever is attacking them."

"A sound idea in principal Jack. However, what if you cannot defeat the attacker?" Celestia asked.

"And here's the minor catch to this plan." I replied, "If things turn out that way we can blast it with the elements of harmony. But in order to do that..."

"We would need to bring in my sister and her friends." Shining said.

"Your sister? Who is she and what do she and her friends have to do with the elements of harmony?" I asked in confusion.

That got a laugh out of almost everyone there, confusing me even more.

"Big brother!" Twilight exclaimed as she glomped Shining armor on sight, which left me reeling.

"What? But...But the two of you are nothing alike!" I asked while scratching my head.

"I do concur, my dear Twilight. Why did you not tell us you had a brother, let alone that he is captain of the day guard?" Rarity asked, making Shining raise an eyebrow and Twilight go red.

"W-well...It just never came up..." She stammered while looking down and kicking at the dirt with her hoof.

HNNNNNNNNG! TOO ADORKABLE! With a hand clutching at my chest, my body fell to the ground as my spirit was forced to take a few steps back to keep upright. I looked between my spiritual hand and my body a few times. I couldn't help but grumble bit. I was killed, not by a demon lord or anything remotely epic. Heck, even Celestia throwing me into the sun for kissing her sister would be more appropriate. But no, I was killed by a deity be damned CUTE-ATTACK!!

Oop! Healing's done. Rebooting systems now.

PoV: Fluttershy

I watched in shock as Jack had what seemed to be a heart attack. I quickly snapped out of it and kneeled by his side, performing CPR.

Once...Twice...Three times...Tears started to appear in my eyes before Jack took in a massive breath.

"Great deities above! Of all the things to die from..." I heard him mutter as he sat up while massaging the bridge of his nose. He looked around and noticed my position. "Oh, hello Fluttershy, what are you doing on your knees, next to me of all people?"

Oh Celestia why did he have to word it that way? I haven't told anyone but Rainbow dash but I am a large fan of...Adult media. My mind started going into overdrive as most of the blood in my body flowed into my wings and face.

When Fluttersy's eyes rolled into the back of her head, Rainbow Dash was quick to get behind her and keep her stiffened wings from hitting the ground. I couldn't help but smirk a little. The night before last Luna had finally told me who it was that had the wet dream about me. Of course the first thing that came to mind was...

'It's always the quiet ones.'

After Fluttershy had recovered and Celestia had explained the situation, the girls agreed whole heartedly to help. With that, my plan was approved.

So here I was, meditating in the throne room to both be ready to switch at any time and warn the others. It's almost midnight, so if the attacker's going to-There!

"Heads up, it's here!" I shouted, "Garden near the fountain! I'm going!"

With those words I switched just as the others started to rush out the door.

When I arrived, the first thing I saw was a single night guard attacking the others. I quickly restrained him, only for a black mist to escape his mouth as he went limp. The mist possessed another guard and kept up the attack.

"Well that makes things more difficult." I said with a grimace as I began deflecting all of the magical attacks while blocking the physical ones with shields formed from my sand. Things went on like this for about fifteen minutes until the girls arrived and blasted the guard with the elements.

The mist was quickly ejected and coalesced into a very familiar form.

"Nightmare Moon!" Twilight gasped. There was a definite difference in Luna's dark side however, Namely that she was missing her wings. Two guards quickly held her arms while another put a horn ring on her to keep her magic restrained.

"Let me go you fools!" NM began to shout, "I need this! I need this sustenance to survive!"

As she spoke, she was glaring at everyone there, though I noticed she was looking at every male there with slight undertone that I couldn't quite place. I had a suspicion, and synchronized with an alternate of myself who was an empath.

Immediately, I was slammed with three emotions in major amounts. The anger was expected, the grief was slightly surprising, but the third...

"Luna, use empathy on her. I think her reason for attacking will make a lot more sense." I suggested. She gave me an odd look before taking it. It took a few seconds for shock to register on her face, then she had to cover her mouth with her hand to hide a massive grin.

"Can you feel that?" I joked, which broke the camel's back as she rolled on the floor laughing. The others looked between us for a few moments in confusion as NM glared at us.

As Luna regained her composure, I whispered our discovery into Celestia's ear, which made her face glow so red I was sure she almost went supernova. She immediately looked to Luna for confirmation and received a nod in response. With a sigh, she ordered her guards to release NM into me and Luna's custody but leave the ring on her.

As NM looked between us in confusion, Luna took on of her arms while I took the other and we dragged her into Luna's room.

Yup. That last emotion I felt was LUST!

The next morning, NM (Or rather, Nyx as she insisted we call her) was a completely different person. Apparently having over a thousand years of negative emotions and lust shoved onto you really screws with your psyche.

Nyx now acted more like a total hippie who was on an eternal high. Her manner reminded me a lot of Luna Lovegood from Harry Potter. A lot of what she said didn't make sense to most, but thanks to kaleidoscope I realized that she was talking about things from other dimensions. Thus we bonded over the craziness that was the multi- and omniverse.

It only took about a day for Luna to want to bring her into the herd. I agreed whole heartedly.
