As she watched Adrian walk out with Princess Celestia, Twilight Sparkle felt more angry and miserable than any other time in her life. What made it worse, was the fact that she really had no right to be. Twilight knew that Adrian wasn't her's and that she shouldn't feel angry at Princess Luna just because she was showing romantic interest in the same pony she was interested in.

"So why do I still feel like I'm having my heart ripped out?"

Twilight wanted to be happy that Princess Luna had found somepony who made her happy but she couldn't, it just hurt to much. Then again maybe Twilight was reading too much into this, it was possible that Adrian was just friends with Luna and she had misread things. Twilight couldn't even convince herself, even if Adrian saw Luna as just a friend it was clear Luna wanted more. Twilight didn't understand how she had gotten so attached to Adrian so fast, no that wasn't true, she knew exactly how. Twilight loved her friends, but Adrian was the first pony she ever met who she was able to have a true intellectual discussion with since coming to Ponyville. Her friend's were by no means stupid and in some areas were even smarter than her. But none of Twilight's other friend's were book smart, so to speak, but Adrian was able to understand almost everything she talked about. Even more important Adrian made Twilight think, he asked questions and said things that made her see things in new ways. The only other pony who had ever challenged her mind as much as Adrian did was Princess Celestia. Twilight thought back to a conversation they had about magic not so long ago. . .

"So what you're saying is that magic is actually the manipulation of a form of energy that is interwoven into the very fabric of your reality?" Adrian asked in awe.

"Yes." Twilight replied smiling, impressed he grasped the concept so quickly. "But it's also able to be used without any conscious effort, that's how pegasi fly and walk on clouds and where earth ponies get there strength." Twilight elaborated.

"It sounds like a large number of life forms in your world evolved ways to use this energy in some manner or another. Like a dragon's fire breath or the cocitrice petrifying gaze, right?" Adrian asked remembering Twilight's mentioning such creatures earlier.

"Yes! Exactly!" Twilight almost squealed, excited to finally have somepony who could extrapolate things with the ease of a scientist.

"So what do you call this energy?" Adrian asked.

"It's called, Mutable Harmonic Resonating Quantum Cosmic Energy, but we call it 'Mana' to save time." Twilight replied.

"So why are unicorns the only ones who can control mana consciously? Is it a matter of biology?" Adrian asked thinking that a unicorns horn might be some sort of specialty organ for the purpose of mana control.

Twilight had to consider that one. "Well it is partly that, but I think it may have more to do with the fact that unicorns have a way of generating mana themselves, though we aren't it's only source. All creatures in our world generate a little mana unicorns just seem to make more and we can boost the amount of mana we create with training and practise. But the strongest mana producers are Alicorns, in terms of power output if a unicorn was a furnace an Alicorn would be more like a megavolcano."

"That would make them akin to gods, wouldn't it?" Adrian asked with a slight bit of scepticism, though on reflection he decided that if this world had mages, why not god's?

"We don't worship them, but I guess you could call them that, although they don't see themselves that way." Twilight responded.

"Twilight you said that all life in your world generates mana, right? So what about me? And how will the ambient mana affect me over time? Assuming it affects me at all."

Twilight had not been able to answer those questions, but to her it was wonderful that she now had a whole new and unique line of inquiry to examine. Twilight had begun falling for Adrian when she realized he was a scholar more than anything, and that he valued knowledge just as much as she did. Adrian also had a sort of odd charm that made him an absolute joy to be around, and even though he was not a pony she found his unusual appearance very enticing for some reason. Twilight had thought it was just an innocent crush, but when Luna looked at and spoke to Adrian, Twilight realized just how much she wanted him.

Twilight was surprised when Adrian came back inside with an incredibly serious look on his face, and his voice was disturbingly calm when he spoke.

"Twilight can I speak to you for a moment alone?"

Twilight just nodded and followed Adrian down into the cellar where he had been staying, Twilight felt her anger flare when she saw Luna was waiting for them.

"What is she doing here?" Twilight asked in a much colder tone than she intended.

"I asked Celestia to send her here, because this concerns her to." Adrian replied smoothly, pretending not to notice Twilight's tone.

When they were all comfortable Adrian took a deep breath, hoping he could resolve this without getting teleported into the center of the planet.

"Ok, I am going to be blunt, Princess Celestia told me that the two of you like me in a 'More than friends' kinda way, is that true?"

Twilight and Luna were both too surprised to answer, after all, they hadn't told Celestia how they felt and never thought she would tell anypony without talking to them, so they simply nodded.

"Ok, well I won't lie I think you two are amazing, and having either of you as a gir- sorry marefriend would be wonderful. But I won't choose one of you over the other, I like both of you too much to break either of your heart's. All I can do is promise that I won't choose anypony else either, I'm sorry I know you probably want to-".

Adrian stopped mid sentence when he noticed Luna had an odd smile, not a devious smile just, odd.

"Uh, Luna, why are you smiling?" Adrian asked slightly concerned, after all he couldn't imagine that "No" was a word a princess slash god heard very often.

"Well, there is another option if Twilight is open to it." Luna giggled with a mischievous glint in her eye.

Twilight looked confused for a moment, then she facehoofed, and smiled.

"Of course, I completely forgot about that!"

Adrian was starting to get a little worried, he could think of a myriad of things they might be talking about and all of them were rather unpleasant.

"Oook, want to tell the clueless human what you two are talking about? FYI if it involves a guy named Solomon I am going to be very put out."

The two mares didn't know who Solomon was, but decided to explain the old Equestrian custom.

"Well. . ." Began Twilight, "you see, in the past Equestria has faced a recurring problem of unequal gender ratios."

Adrian was already getting an idea of where this was going, but he was certain he had to be wrong.

"And, how does this relate to our current dilemma?" He asked, confidant that his first guess was impossible.

Luna finished explaining, confirming Adrians first guess was right after all.

"Equestria has always had more mare's than stallions and sometimes it was so great a difference that there were ten mares for every one stallion. So a law was decreed that permitted a stallion to partner with more than one mare if the mares were willing, and forming what we call a Herd." She said joyously.

Adrian felt both excited and a little freaked out.

"Whoa, whoa, so, you two are going to what? share me."

When luna and Twilight smiled and nodded, Adrian felt distinctly lightheaded for a moment.

"And, you two are ok with this? I mean don't get me wrong, this is every man's dream, but can you two really manage to handle sharing a lover without killing each other?".

Twilight nodded.

"I have no problem with it, all I care about is that I can be with you, I was a little upset but that was before I remembered about the, Herd Act."

Adrian assumed that "The Herd Act" was the name of the law they were siteing, also he was quite certain that Twilight had been more than a little upset.

"Ok, girls I'll give it a shot."

Less than twenty feet from the most life altering discussion of Adrian's twenty two year life, Rarity, Pinkie, Rainbow, AJ, Fluttershy, and Spike were awkwardly trying to make small talk with Princess Celestia. She had come in right after Twi and Adrian left, while everypony in Equestria loved the Princess, it was still a little intimidating to be face to face with an immortal godlike entity and leader of the country. The girls and Spike had been silent so far, eventually Celestia decided to start, by inquiring about their strange new extradimensional friend.

"So girls, Spike; after getting to know him what do you think of Mr. White?"

The girls and Spike looked at one another, each worried about saying something that might accidentally paint Adrian in a negative light, until finally Rainbow spoke.

"He's awesome, he tells the coolest stories about how humans use technology to do all kinds of things because they don't have magic. He told me they can build these amazing machines called jets that they use to fly, and that they can go faster than sound and the pilot's need these special suits so they don't black out and. . ." Rainbow was interrupted by Applejack.

"He tol me tha humans use somthin called gee-net-ick engineering ta make plants do all kinds a crazy things, but he said there was some kinda problem with it caused by corporations, whatever they are. He knows an awful lot about plant's an how ya can use em for things like medicine."

Fluttershy was the next to speak.

"Adrian is so fascinating he knows all about animals, even I didn't know some of the things he does."

Rarity chimed in with.

"He is a true gentlecolt your highness, he has wonderful manners and could not be a more charming guest."

Spike also spoke up.

"Adrian is really cool, he knows all these amazing stories about dragons and zombies and demons and all kinds of things like that."

Finally Pinky pie who had been nodding in agreement while the others spoke decided to give her two cents worth.

"He loved the cupcakes I made him and he's so nice, plus he never tried to eat my brain even once."

The princess was slightly puzzled at Pinky's rather odd praise for Adrian but decided it was some kind of joke.

"It sounds like you all are becoming fast friends, I'm so glad to hear that."

Celestia may have been smiling outside, but inside she was very worried. She knew that Luna and Twilight were both levelheaded ponies but that didn't matter much when love was involved. Love had a way of turning even the most sensible pony into a completely irrational nut, and when two mares wanted the same stallion it could get very ugly. Still, ten minutes had gone by without any sign of fighting between Luna and Twilight, "so far so good" Celestia thought.

"I wonder why Adrian wanted to talk to Twilight alone." Rainbow Dash asked offhandedly.

Everypony in the room stared at Rainbow with a disbelieving expression.

"Yall are kidden right?" asked Applejack.

Rainbow scowled.

"Uh, if I knew why would I ask? besides they didn't tell you what the reason was either, I was here the whole time and Adrian never said a word to anypony but Twilight."

Applejack smiled.

"They didn't need ta say nuthin, haven't ya'll noticed how Twilight and Adrian look at eachother?"

"Or how luna was acting around Adrian?" Asked Rarity.

"Yeah Dash, even I figured it out." Spike said in a slightly condescending tone.

Rainbow glared at her friend's.

"Ok, fine let's hear you guys's theory."

Rarity sighed before replying.

"Dash darling, it's obvious that both Twilight and Luna are infatuated with Adrian."

"Infatu-wha?" Rainbow asked confused.

"Twi an Luna have a crush on Adrian." Applejack clarified.

It took a moment for dash to process that, before she responded.

"Seriously?"

As Dashes friends were explaining to her Adrian was digesting what his two newfound love interests had told him. First and foremost all members of a herd were equal, second if a mare wanted to join the herd then it had to be agreed to by all members of the herd. A herd could be any size but it was rare for one to have more than about five to six members, also only one male to a herd unless the original male was bisexual. Same sex herds were permitted but they were not very common. Homosexual relationships were in no way considered odd or bad, Adrian had asked because even if the answer didn't affect him personally, prejudice due to sexual orientation was among the things he detested most in the world. Finally Twilight and Luna agreed that since Adrian was going to be in Canterlot he should go on a date or two with Luna.

Adrian was amazed at how quickly Twilight had gotten over her jealousy, "It's incredible how psychologically different they are from humans, no wonder they never had a real war.". Adrian was constantly surprised by how easygoing ponies were when compared with humans. If a strange lifeform crashed down in the middle of a human town it would have been treated very differently. Adrian shuddered when he thought about what humans did to things they didn't understand. The more he learned about this world the more Adrian felt like he wanted to stay, here leaders were not corrupt, here big business was not in near absolute control. Equestrians were not instinctively driven to commit horrific acts in the name of greed, and they did not automatically hate things that were different. Adrian was awoken from his pondering by the sound of Luna's voice.

"Adrian? are you well?"

"Huh? oh sorry girls I spaced out for a moment, this is a lot to take in."

Twilight smiled.

"It's fine we were just saying that we should go up and let everypony know what's going on, they probably think Luna and I are going to start hurling spells at each other."

Adrian nodded giving a theatrical bow.

"Ladies first."

Back upstairs everypony froze as they heard the hoofsteps of Twilight and Luna ascending the basement stairs, everypony held their breath as the doorknob turned. Nopony spoke as Luna, Twilight and Adrian stood in front of there friends, till Adrian spoke.

"Ok first the good news, Luna, Twilight, and I have talked things over and we found a solution to the problem."

Everypony (Celestia included) breathed a sigh of relief.

"Which brings me to the better news, Luna and Twilight will be forming what I am told is called a 'herd' on a trial basis. Also I would like to point out to their family and friend's, that in the event that this news drives you to homicidal mania, this was not my idea."

Adrian was prepared for a lot of shouting, anger, and the possibility of Celestia incinerating him where he stood, so he was rather surprised at the response he got.

"Congradulations!"

"Way ta go girls!"

"Oh how wonderful!"

"Oh, that's so romantic!"

"Awsome!"

"Allright Adrian!"

Only one pony remained silent.

"Sister is something wrong?" Luna asked.

Princess Celestia had not said a word, and she wasn't smiling, getting to her hoofs the princess slowly advanced on Adrian never taking her eyes off him. Adrian locked eyes with the sun princess and despite being terrified he refused to show it in any way. Refusing to back down even when every cell in his body was screaming at him to run. Celestia stopped with her face inches from his, Adrian felt like an ant about to be squashed, if he had been watching this in a movie he would have called himself a suicidal moron. For a long time the goddess of the sun and the impudent mortal continued to glare at each other, until the corner of Celestia's mouth started twitching. Celestia managed to keep her face serious for about three more seconds before she broke down laughing.

"Hee, s-sorry I just- ha,ha, couldn't resist, HA,HA,HA, the look on your faces was hilarious, Lulu, Twilight you looked hee,hee, like you thought I was going to eat him, HA, HA priceless!"

Luna looked like she wanted to strangle her sibling.

"SSSIIISSTTERR!! I am going to KILL YOU!"

So saying Luna levitated a number of cushions off the floor, Celestia let out a small "Eeep" before running out the door, laughing as she doged her sisters hurled pillows with ease. Luna started chasing after her big sister continuing to hurl pillows and promises of vengeance, it was safe to say that this was a side of the princesses that no pony had seen before.

"Um, do you think we should do something?" asked spike.

"Yes." replied Adrian, "We should make some popcorn and get a camera.".

Author's Note

Be honest, do you know any siblings who don't tease each other like that on occasion? Also if you spent a thousand years away from your sibling wouldn't you want to enjoy being a sister/brother again?
