Much happened after the defeat of Sombra.
First of all, Chrysalis didn't hear the end of it when she learned she had been saved by her enemies. When inquiring why he hadn't let the clutches of Tartarus drag her to Hell along with Sombra, Discord simply told her that, unlike her, he was not vengeful. Not anymore. This moved the Changeling Queen to the point that she released every pony of the Royal guard of her control, and even freed the Royal Sisters from the stone prison, and decided to accept whatever punishment they would give her. Celestia was surprisingly mercifully, much to the ire of most pony population, the mane six included. She allowed Chrysalis and all of her Changelings, minus Stormfly and Mist Wing, who were no longer part of the Hive, to leave. After Chrysalis and her Changeling Hive left, they were never heard from again. Everypony assumed she had decided to give up on conquering Equestria, and preferred to try and live a normal life. But someponies were surprised when sometimes, new-coming neighbors had flashes of green every now and then.
Stormfly had initially wanted to leave and find someplace else to raise his daughter, but Screwball convinced him otherwise, even offering him to stay at the library, despite her parents' protests. Eventually, Screwball's puppy eyed face convinced both the Changeling to stay in Ponyville and Twilight and Discord to let him stay with them at the library. At least unit he found someplace else in Ponyville to live in.
Fukkuteru, having no reason to return to Saddle Arabia (the temple he used to study was gone, after all), decided to make his nest at a nearby cave in Everfree forest. He would visit his new pony friends every now and then, but it took a while for the citizens of Ponyville to warm up to a Kuros. However, when they came to accept his as one more member of the family, his visits became almost daily, and at times he would help wherever he could.
The mane six, Discord, Shining Armor and Cadence returned to Canterlot to wait for the so expected day. Princess Celestia pampered Twilight and Cadence as an old grandmother would and wanted them to be as comfortable as possible after all the events. Stormfly and Fukkuteru, although thanking the Princess for the invitation, politely declined it, saying that the ponies from Canterlot would not be as welcoming as the citizens of Ponyvillle. Besides, Fukkuteru wanted to taste those 'famous' cupcakes everypony often spoke about.
In other words, everything was back to he way it was...
The doors of Canterlot Hurricane Hospital burst open as Discord brought Twilight, who was sitting on a wheelchair, sweating uncontrollably and breathing heavily, followed by the rest of the mane six. Shining Armor was next as Cadence, in a similar situation as Twilight, was brought into the hospital on a wheelchair.
The mare in the reception, with a white coat and a straight pink mane with creamy steaks, was taken by surprise when Discord nearly ran Twilight against the counter.
"Her water's broke!" He cried out in a tone which would have made everypony laugh were the circumstances different. "We need help!"
The nurse quickly nodded. "I understand, but first you'll have to check in, mister-" she was interrupted abruptly when Discord took her by the shoulders.
"Check in?! Where?! At the concierge's desk?! Why are you being so mean with me?!"
Applejack rolled her eyes and addressed at the nurse. "Ignore him, he's just ah little panicky."
"Shining, it hurts!" Cadence cried out, drooping her ears and breathing heavily.
"Don't worry, Cadence! Everything will be fine!" The white Unicorn assured her as he held her hoof. "You'll be fine!"
The nurse, after giving Applejack the papers to fill out, immediately galloped to the mares' side. "How frequent are the contractions?"
Discord whined. "Paw. Constant." Twilight was in So much pain that she did not realize she was crushing her husband's lion paw.
The nurse rushed through the white doors leading into maternity ward, and in mere seconds was back with a group of nurses who took Twilight and Cadence from their respective husbands and pushed their wheelchairs into the maternity ward. Before going through the doors, the nurse from the counter gave Discord and Shining Armor a last glance.
"In a few minutes you'll be able to accompany your wives at the birthing room, just wait."
Then she disappeared through the white doors.
Many ponies consider the waiting room to be boring, silent and an increase in anxiety.
Princess Celestia and Twilight and Shining's parents, Night Light and Twilight Velvet, arrived shortly after Twilight and Cadence were taken into the delivery room. Discord and Shining Armor soon went to accompany their wives in their hard task, but the others were told to wait. The doctor would come to see them after the foals were born and the mothers taken into their room; they had asked to be placed in the same room, for they wanted to meet each other's foals. There were also other ponies waiting, families or individuals who were waiting to hear the fate of a loved one.
After two hours of playing poker, napping and walking around the waiting room, Doctor White, whose coat was, ironically, a dark gray color, walked out from the white doors and called out, "Familiars of Twilight Sparkle and Princess Mi Amore Cadenza."
Immediately, he was surrounded by the mane six and Twilight's parents, but it was princess Celestia who spoke, "How are they, Doctor? Are the foals alright?"
Doctor White smiled warmly. "Congratulations, everypony. Princess Mi Amore Cadenza gave birth to a healthy colt. But Miss Sparkle had a little more effort to do to birth her foals-"
"Whoa, whoa, whoa, there doc!" Rainbow Dash exclaimed, "Foals?"
Doctor White nodded, "She had triplets. Two healthy colts and a filly. Mr. Discord fainted when the firstborn's head was crowning, but I'm not sure if he fainted out of excitement or shock."
Immediately, everypony started chattering in excitement about the foals, and laughing at Discord's antics, but Night Light addressed the doctor once more. "Can we see them?"
"Of course. Follow me, please."
The room Twilight and Cadence had been accommodated into was painted in a soft white, and the beds' sheets were colored a soft red. When the group of ponies entered the room, they all awed when they saw Cadence holding a small bundle of blue in her hooves, Shining Armor by her side. Twilight Sparkle, on the other hand, was holding three, two wrapped in blue and one wrapped in pink. Discord was staring at his triplets, his chest swollen with pride and his eyes with tears. The thing the new mothers had in common was that their manes were a mess.
"Aaawww!" Pinkie Pie was the first to react, "Four little foals for us to play with! Who hoo!"
Rarity immediately hushed her, "Pinkie Pie, the babies surely must be trying to sleep!"
Twilight smiled at her friends, "It's okay, Rarity."
The Twilight parents, the mane six and Princess Celestia walked closer to the beds to take a look at the newborns.
Cadence and Shining Armor's colt had light sapphire bluish gray coat, almost similar to his father's. His straight mane was a moderate sapphire blue, like Shining Armor's, but the streaks were colored dark violet and pale gold, no doubt from his mother's side. His big cerulean eyes were looking at the ponies around him curiously, and his hoof was entangled in his mother's messy mane.
Twilight and Discord's triplets were a completely different story.
The firstborn colt was identical to his father. He was a smaller, chubbier version of his father; he had a round head colored amber yellowish gray, and big goat-like ears, and a single fang on the left side of his snout. However, he had obvious traces of his mother's genes. He had a spiky fringe of moderate sapphire blue with moderate violet and brilliant rose streaks. The tuft of his tail, poking through the blankets, was colored the same as the fringe of hair. His eyes were moderate violet with light yellow.
The second colt looked completely normal; he was a normal unicorn foal with light mulberry coat, close to his mother's color, and his mane was a pale white, like his father' tail tuft. His eyes were a moderate violet, like Twilight's, and his horn was a little curved. It would probably have the same shape as his father's goat horn.
The filly, like her oldest brother, resembled Discord more than anything, but her head was a pale light grayish mulberry. The fringe of hair on her head and the tuft of her tail was white, and her eyes were completely like Discord's: brilliant crimson with light brilliant yellow. But the mane on the back of her head was the same color as her mother's mane.
"So, how will you name our grandchildren?" Twilight Velvet inquired as she stroked one of Twilight's colts.
"Well, after thinking it thoroughly, Cadence and I decided to name our colt Blade Kiss." Shining replied, stroking his son's mane gingerly.
Princess Celestia walked closer to Twilight Sparkle and took a look at the triplets. "And how will you name the triplets, Twilight?" She smiled warmly.
Discord and Twilight glanced at each other before Twilight motioned to the oldest of the triplets, "This is Night Charge." She looked at the second. "This is Lavender Dusk." And finally, she muzzled her snout against the filly, "And this is Astral Aurora."
They were together.
They were a family.
And they were happy.
