As everyone made their way to Twilight's library Pinkie asked the boys all her typical questions. You know, like do they like parties and cake and parties with cake and what kind of cake do they like when's their birthday basic Pinkie Pie Q n A.
To answer her questions San loved any chocolate cake, Baygo preferred strawberry shortcake, Chuan just loved any cake, and Hotaru preferred pie over cake because most are made with fresh fruits.
Anyway, back to the main story everyone finally reached the library, and they all took a seat.
Sweetie, Gabby, and Apple Bloom all sat down next to their coltfriends on separate oversized chairs while Scootaloo just sat on Hotaru's lap wrapping her arms around his neck.
The brothers watched in amazement as Twilight made multiple scrolls and parchment float around her before setting them all down on a desk. Seeing their expressions the girls giggled.
"What's the matter haven't you ever seen magic before?" Apple Bloom asked the four brothers.
"Not like this we've seen our mother talk to her previous lives and open passageways through the spirit world but nothing like this," Baygo said still amazed at what they saw.
"That was just a simple levitation spell all Unicorns can do it." Sweetie Belle said, demonstrating by lifting a book with her magic.
"Okay, before we continue I would like to apologize for what has happened to you and for the way you were treated when you arrived," Twilight said with remorse in her tone.
The brothers looked at each other than to the one sitting next to them or in Hotaru's case on him before Baygo spoke." It is quite alright your highness, no one was hurt and we are all friends now and will be for the rest of the time."
"Thank you so much for this, it means a lot to me, I mean us, all of us," Twilight said, gesturing around the room for everyone." Now let's begin, shall we?" She said as she levitated some paper and a quill over to her.
"So first off when you introduced yourselves, you said you were the sons of Korra why is that?" Twilight asked ready to write our response.
"Korra is our mother and she Is the Avatar so it is our way of showing respect," San said looking around at everyone.
"Wouldn't you normally say you the son of your father, not your mother?" Rarity asks still a little peeved at how her sister is acting.
"That would be true, but we do not have a father, or I should say we never had one," Hotaru said as he saw the confused looks on all the girls." Let me try to explain you see our mother never had a relationship with a man, in fact, she was a virgin until she started her relationship with Asami Sato or as we like to call her mom."
"So I take it that your mother is what we call a Fillyfooler then?" Rainbow asked with as much tact as she could muster.
The boys looked confused until Gabby leaned over and whispered in Baygos' ear.
"Oh, you mean a lesbian then yes, she was," Baygo said which made the other boys nod.
"If she was a filleyfoo... lesbian then how in the hay did she up and get pregnant with you four, "Applejack asked scratching her head.
"Yes, I would very much like to know that as well Darling," Rarity said.
"Actually, I think all of us would like to know that, "Twilight said as she looked at everyone.
"To be honest, we don't know neither does our mother or any of the Spirits. All they say is that one morning she woke up and she was pregnant, but here is the biggest mystery she was and still is infertile. So how could she become pregnant with not just one but four babies at once?" Baygo asked.
"Well, I'll have to look that up next time I'm in Canterlot there has to be some form of spell that would cause it, "Twilight said as she looked up from her notes." Now let's continue, shall we? Can you tell me more about this bending of yours where did it come from and how are you able to do it when you have no magic at all?"
So for the next three hours, we explained and demonstrated the different types and styles of bending.
First up was San for his demonstration of earthbending one of the crystal walls into more shelves for books and, he then metal bent one of the empty suits of armor into a statue of our mother in her avatar state with the elements around her and everything. He did refuse to show lava bending due to it being too dangerous and he still was learning to control it.
Next up was Chuan he went about and showed off waterbending he even got Rarity into it by encasing her in a bubble of water but keeping her completely dry. He also showed them his healing ability when Rainbow Dash was hovering and back into a bookshelf having a very large book fall and strike her head.
"That is so amazing," Both Twilight and Fluttershy said.
"Oh, that's nothing I can also do..." Chuan was about to continue when he felt Hotaru look at him and mentally tell him to shut it.
"What else did you say you can do Chuan?" Twilight asked only to be interrupted by Hotaru answering.
"The other form of bending Chuan can do is considered Taboo and should only be done in very dire emergencies, and I suggest he show it to you in private," Hotaru said in a very stern tone causing everyone to cringe a little.
"Oh, ah okay, then shall we move on?" Twilight said a little hesitant from the way I spoke.
"I am terribly sorry your highness, it's just the bending art my brother speaks of is considered to be barbaric and cruel," Baygo said bowing to Twilight.
"It is quite alright, I understand and it shows true conviction to your beliefs, "Twilight said, walking over to stand in front of Baygo. "How about we take a break for some lunch before we continue?" Twilight asked receiving around of stomachs growling as her answer making everyone blush and laugh.
Baygo excused himself and went outside a few minutes later he returned with four bags that were familiar to his brothers.
"Hey, aren't those our bags where did you get them?" Chuan asked as the brothers came over to take their own bag.
"Remember, we had Imoto carry them for us and since she's here with us so are our bags," Baygo said smiling before turning to Twilight. Princess as a show of gratitude to you and your friends, we would like to make a traditional meal from our world for all of you. And you do not have to worry it will be completely devoid of meat."
Hearing this the girls looked a little confused for a moment until Fluttershy explained that the brother minus Baygo were omnivores while he was vegetarian.
After a few minutes, Twilight and her friends agreed, and then they watched in amazement as the brothers took control of the kitchen. First, they saw Hotaru use Firebending to light the stove.
"Did you just see that he just shot fire out of his hand," Rainbow said looking around at the other girls?
"Yeah, he's totally awesome, but still not as awesome as you Rainbow," Scootaloo said with dreamy eyes until she looked over at her mentor big sis.
"Thanks, squirt but seeing as he's your coltfriend it's okay if he's as cool and awesome as me, "Rainbow said pulling Scootaloo in for a big sis hug.
Sitting at the kitchen table all ten girls watched as the boys worked their magic. The sounds and smells that were coming from the stove and counters were like nothing they had ever heard or seen. And after everything was done the fourteen sat down to their simple meal.

and Green tea.
All the girls were enjoying their meals if the Mmmmm's and ahhs were any indications.
"Where did you learn to cook like this your mother?" Fluttershy asked which caused the boys to start laughing.
"Sorry, Miss Fluttershy we did not mean to insult you or anything but, to be honest, we learn to cook from our Grandmother because, well..." Baygo was hesitant to finish when Hotaru did it for him.
"Our mother couldn't even heat up a pot of water without setting it on fire," Hotaru said bluntly as his brothers all nodded in agreement.
"That sounds just like you Twi," Pinkie said with a smile making all the girls giggle.
"I'm not that bad anymore both, Spike and Flash said, I've gotten a lot better, "Twilight said with a blush on her muzzle.
"Yes and thankfully you do not make toast that you can drink through a straw," Rarity said, looking at her little sister who responded by sticking her tongue at her which Rarity responded the same before they both laughed.
Everyone laughed at all this fun until it was time to get serious again after cleaning the table and dishes they made their way back into the library. Everyone took their original places again, except this time, Sweetie, Gabby, and AB followed Scoot's example and sat on their coltfriends laps as well. This time no one said a word about it. With all that settled Twilight wanted to continue their conversation about bending.
"So by process of elimination, I would say that Baygo your element is air since Hotaru started the stove at lunch," Twilight said looking a little smug.
"That is correct I am an Airbender and Hotaru is a Firebender one of the most powerful, I would say next to our mother there is no one stronger, "Baygo said looking for his brothers for confirmation.
"Thank you so much, little brother, for putting me on the spot, you are soooo kind," Hotaru said in the most sarcastic tone he could do.
" Ok, ok enough of that now can I ask where did bending come from?"Twilight asked as she pulled out more paper.
Well, Earthbending came from humans watching badgermoles for they are the original earthbenders," Sal said with pride showing the girls a picture of a badgermole.
"What about the others?"Fluttershy asked after coooing over the picture.
"The first waterbender was the moon or Yue, man would watch as the moon would push and pull the tides then one day a hunter was lost in the ocean and he prayed to the moon to help him get home. The moon spirits heard him pray and came down to earth, there they taught man and his people how to bend all water, and they like it on earth so much they stayed but doing so it may it possible for them to get hurt or die. (For reference watch Avatar the Last Airbender episode 120) 
"You know what I think, I think Princess Luna would love to meet you after all she is Princess of the Moon, "Pinkie said with her trademark smile.
Haring, this made Chuan smile, after all, he never met a Moon Princess before.
What about you Baygo where did Airbending originate?" Gabby asked her Coltfriend.
"Imoto's kind the sky bison were the first Airbenders," He said bluntly.
"Oh is that all I was just hoping for something more," Gabby said lower her head in disappointment.
Actually, Airbending was the first one, man ever learned if I remember the history lessons mother told us, "Hotaru said which made Baygo and Gabby smile a bit.
"And what about Firebending no wait, let me guess the sun right?"Rainbow said with a hint of sarcasm in her voice.
"Yes, how did you know, well actually dragons learned it first, then they taught man, but the sun is the first Firebender, "Hotaru said with the same sarcastic tone she used on him.-
"Seriously, I was just joking, but you mean you learned firebending from the sun?"Rainbow yelled in complete shock.
"Like I said the dragons were taught first, then man, was after he was deemed worthy though, "Hotaru said looking at Rainbow with a smile.
Lowering his head Hotaru took in a deep breath. "But of all the elements, fire is the most dangerous it would be closely considered to be a living thing," Saying this made all of them look confused at him." You see fire does what man can do It breaths, eats, and can reproduce, but if you take away its air or food it will die just like a man the only thing it can not do is think for its self." He said looking at them with a stern expression.
"That makes it sound like fire, is nothing more than pure evil and destruction," Twilight said, lowering her notes to look at him.
"True, but you must remember that even if all seems lost life finds away and even in destruction there is creation,"Hotaru said by showing them by burning a potted flower to ashes only for its roots and seeds to remain unharmed.
After another hour of talking about everyday things Twilight thanked the boys for all their help she began to get all of her papers stacked in order."Now all I have to do is write a letter to the Princesses about you for then everything will be taken care of," She said as she began to write one more time after finishing her letter she used her magic and in a flash of light it was gone." There now all we have to do is wait for a reply and we'll know where we go next."
Mean While in Canterlot
Celestia and Luna were sitting on their thrones in the great hall Half listening to the complaints of another snobby rich pony who thinks they're entitled to everything just because they are a noble. Suddenly, as the noble was about to continue a flash of light shut him up there floating in front of Celestia was a scroll taking it from the air, she opened it and began reading it. This caused the noble to huff which was short as a look from Luna stopped him from saying more.
"Sister is that a letter from Twilight?" Luan asked, leaning over to read what it said."Why did she not send it with Spikes dragon fire?"
"Remember Lulu Spike is visiting Lord Ember in the Dragonlands and he will not be returning for two more weeks," Celestia said as she turned to look at her sister.
"Forgive me, Tia, I had forgotten that so, what does our fellow Princess say in her letter nothing bad I pray?"Luna said as she attempted to read the letter again.
"No, in fact, it is very good news, It seems that four humans have arrived in Ponyville and they hail from the Elemental Nations and are in fact the sons of the Avatar, "Celestia said as she handed the letter to her sister.
"What, you mean to tell me Kyoshi's sons are here?" Luna said with a smile on her muzzle.
"No, sadly this is a new Avatar named Korra and it seems the each of her sons is a master of each element," Celestia said as her sister finished reading the letter.
"Too bad it isn't Kyoshi, I really liked her, "Luna said with a smile.
"The only reason you two like each other so much is all the pranks you pull around the castle growing up," Celestia said looking at her sister who responded with a raspberry.
The noble that was listening to all of this cleared his throat to gain the attention of the princess' look on in surprise as they both ignored him and proceeded to rise from their thrones and depart from the great hall completely ignoring him. Turning to one of the guards for help the guard just shrugged his shoulders.
"I think, court is over for the day you might want to come back Monday and try again," The guard said, to which the noble stomped his hoof and left in a huff complaining the whole way out.
Walking down the hallway, both Princesses make their way to the Royal Gardens there they have a chariot waiting for them.
"Do you think it's a good idea to just show up at Twilights without informing her first sister?" Luna said as she slowed her pace to their destination."Remember what happened last time."
Stopping in her tracks Celestia stood there for a moment. Huffing she materialized a quill and parchment with her magic where she quickly wrote down something, then sent the parchment away before placing the quill into one of the many flower pots near her." There, I just sent her a letter, now she knows we're coming happy?" Celestia said as she continued her trek to the gardens.
"Yes, and I thank you, sister, for I still can see young Twilight so frazzled when we last visited without informing her it was just dreadful," Luna said as she caught up to her sister.
"Oh Lulu, Twilight has been a princess for six years now she should have learned that stress is part of the job by now," Celestia said with a slight chuckle.
They finally made it to the gardens where a chariot waited for them. Climbing aboard they giggled like schoolfillies within moments they were airborne and traveling to Ponyville.
As they rode in the chariot the royal sisters sat in silence until Luna looked out the window and squeeed. "Sister, sister, look, look, is that what I think it is?" Luna said in a childish tone while pointing towards the large furry form outside of Twilight's castle.
Looking where her sister indicated Celestia let out her squee of excitement. "Yes, it is, oh, I haven't seen one in like forever and It looks as fluffy as I remember," She said thinking about their first encounter with flying bisons.
They were both jolted out of their thoughts as the chariot made its landing outside the doors of the Castle of Friendship aka Twilight's home.
"Well, I guess it's time to meet our newest residents of Equestria," Celestia said as she made her way off the chariot.
"Yes, let's, I just hope they are attractive, so we can get to know them more intimately," Luna said with a little sexy devilish smirk.
"Lulu that is no way for a princess to speak," Celestia said with a shocked expression which quickly turned to a grin. "I hope they are too, I haven't had a good rut since before your banishment." She said as she wiggled her hips.
As they made their way to the doors they had to jump back in surprise as the large doors swung open almost hitting the two royals in the face. Standing there was their fellow princess, Twilight Sparkle looks calm and collective but her hair still had a bit of a frazzle to it.
"Celestia, Luna its so nice to see you, what are you doing here?" Twilight said looking from one to the other.
The sisters just looked sideways at each other and were thinking the same thing." Well, here we go this should be fun."
Ten minutes earlier at Twilight's castle
As the girls were telling their new coltfriends of their adventures of when they were younger a flash of light caught their attention. Floating in the air was a scroll right in front of Twilight. Grabbing it, she opened it and started reading seconds later her appearance changed and she began to hyperventilate.
"Darling, what seems to be the problem?" Rarity asked her.
"No no no this isn't good, not now I'm not ready, there's so much to do," Twilight said as she became more frazzled.
Walking over to her Rarity took the scroll and read it herself.
"Oh my, I see what has caused you to become so disheveled," She said, placing her hand over her mouth in shock.
"So are you going to tell us what the big news is are we going to have to guess?" Rainbow Dash asked getting just a little ticked.
Looking at her friend with a glare Rarity cleared her throat. " It just says that the princesses wish to meet our new friends and are coming here."
"Really that is nice of them when will they be here?" Pinkie said, jumping up and down in excitement.
"Now," Twilight said which caused the boys to look at her with some fear.
Seeing this Baygo had Gabby moved so he could get up. Moving to stand in front of Twilight he placed his hands on her shoulders and looked into her eyes. And with a calming voice, he spoke to her." Ms. Twilight look at me you need to calm down and breathe, everything will be fine, we're all here and can help so please relax."
Hearing his voice Twilight looked into his eyes, she felt absolute serenity and relaxed, almost instantly. Taking a deep breath, her appearance changed to normal.
"Thank you Baygo I just kind of get a little freaked out sometimes," She said with a slight blush.
" It is quite all right, sometimes I had to help our mom when she had her little freak outs," He said scratching the back of his head.
What happened next was a montage of events Pinkie took Son and Chuan to the kitchen to make some snacks. While Rainbow Dash, Scootaloo, and Baygo did a quick clean-up with their speed. As everyone else just tittied up the library placing books and scrolls back on the shelves. Watching all of this Twilight was in awe at how everything was turning out in the short amount of time given to them. When everyone made their way back to the library Baygo passed Twilight a little too quickly causing her mane to become slightly messed up when Flash Sentry opened the doors to let them know the princesses have arrived. Hearing this Twilight made a mad dash to the front doors, opening them with a little too much force to greet her fellow princess.
"Celestia, Luna it's so nice to see you, what are you doing here?" Twilight said looking from one to the other.
"We received your letter about the arrival of four brothers and we wished to meet them," Celestia said after she regained her composure after that greeting.
"Oh yes, of course, you would please come in they are in the library," Twilight said as she stepped aside to allow the sisters to enter.
As they walked the hall Luna spoke up. "Is it true that they are humans from the Elemental Nations and the children of the Avatar?"
"Yes, that is what we were told by them, but may I ask why are you not concerned about them being human?" Twilight asked looking at both princesses.
"I believe it would be best to explain to everyone present," Celestia said, looking at her former student with her motherly smile.
Not pushing it further Twilight lead them to the library doors. Opening them the three were greeted by thirteen figures bowing with, "Welcome your Majesties," said by all.
Looking over the group Celestia and Luna's eyes fell upon the four humans who each held the hand of their love.
Both Royals sighed and thought the same thing. " Damn they're already taken."
