Days turned into weeks, and weeks into months; and everything was harmony and happiness for the reunited family. Twilight even stopped her research trying to confirm or refute King Flames’ story. After all, this two couldn’t be the monsters he described. They were polite and kind-hearted ponies; respected for nobility, and military thanks to their great combat abilities and also modesty and good will. And were helping every the Guard to reach their level in the battlefield.
But for them, the most important thing was to spend as much time as they could with their beloved daughters and recently asked them to tell all what they missed; and of course they happily agreed. And considering a very especial night for the Princess of the Moon was coming, that day they told the story of Nightmare Moon. Of how Luna’s jealousy turned her into a dark being whose only goal was to bring the eternal darkness.

When she finished, White Nightmare raised an eyebrow.

“Unbelievable” she sighed.

Luna lowered her head ashamed.

“I know mother, I… was weak, my emotions took the best from me and betrayed my own sister. I attacked her, I forced her to use the Elements of Harmony against me…”

White chuckled happily.

“No, you don’t understand darling, what you did is past history. I’m not mad, is just I’m a little surprised Luna. Somehow you demonstrated to be connected with the past doing such things”

Twilight shivered, a small gesture that wasn’t unnoticed by the Old Generals. But ignoring it, Dark Moon explained to the family:

“Not lowering the moon was one of the old Death Ride’s characteristic punishments. He used to calm any possible insurrection without using violence”

“There’s no worse crime than hurt another pony” said White Nightmare. “That was one of your grandfather’s most sacred rules; since those were war times and we should stay together; and when he faced insurrection, my father limited himself to show the people why they needed him”

Luna and Celestia just awed in surprise. It was strange, but they had to admit those were different times. Dark Moon continued:

“But the most important thing was that the last time he did that, you were a baby; perhaps you had a week or two. It was only a week and a half before the dragons invaded us and… well, you know, let’s leave it there”

“Dark Moon, allow me to correct you” said White Nightmare: “the most important thing was the name you chose for you Luna. Nightmare Moon; Nightmare like me, and Moon like your father. It seems like you based your actions in old memories, I’m still astonished"

The sister exchanged a small look of surprise while Twilight and Pip just raised an eyebrow, but then happily thought about all the fun they had during the Nightmare Nights and it was interesting knowing the real connection between Luna and the past.
After a few minutes of silence, Dark Moon asked:

“Luna, do you mind to show us your form of Nightmare Moon?”

Luna blushed a little, but after a while she made her transformation into the dark alicorn. White Nighmtare smiled impressed and Pip only shook his head in delight at his wife’s transformation; by their way Twilight and Celestia shared a small chuckle.
But Dark Moon just sighed clearly annoyed.

“You know? You’re much more prettier when you look exactly like me”

The family laughed happily, moments like that were worth to keep having. They were a great family and everything was completely fine.

At the next day, the Royal Family had to prepare for their duties. The last day somepony asked for an audience with the four of them: Celestia, Luna, Twilight and Pipsqueak. It wasn’t something very common, but not completely unusual. In fact, in some occasions the ponies asked for Candace’s and Shining’s presence as well.
But that day there were only the four of them so they sat on their respective throne and made the Guards a sign to let the ponies pass.
They were twelve mysterious-looking ponies, white as snow and covered by light blue hoods that completely covered their eyes. When they saw the monarchs, they bowed respectfully. The monarchs made a small nod as a welcome gesture and Celestia smiled.

“Greeting my little ponies. Yesterday you sent a message telling us you had something very important to discuss with us. So go ahead, what’s so important that you need all of us?”

The older one made an step forward and spoke with an emotionless voice:

“Is a pleasure to meet you, Rulers of Equestria, protectors of Harmony and Peace. We’re here to ask only for one thing: the well-known generals White Nightmare and Dark Moon shall come with us to the No-one Lands to be judged and condemned to death penalty. They should answer for their crimes in hell, where they’ll receive the punishment for their actions of the past”

Silence, only silence for a while. But Luna walked to one who spoke:

“How dare you?” She asked in normal voice but ready to reveal her Canterlot one for the end: “How dare you to dictate a sentence? YOU’RE NO ONE TO COMMMAND US, WE’RE HERE THE RULERS NOT YOU, AND…”

The pony shrugged with calm.

“Be careful how you speak to us, little pony. You don’t know how to recognize your superiors when you see them?”

“My superiors?” Asked Luna outraged.

“YOU SILENCE SIMPLE PONY” Yelled the older one, with a voice hundreds of times most powerful than the Royal Canterlot Voice. A freezing wind came out of nowhere and covered both windows and floor with a thin layer of ice. “WE’RE NOT PONIES LIKE YOU OR THE OTHERS, WE’RE THE ANCIENT GUARDIANS OF THE WORLD, THE ONES WHOSE COWARDNESS CONDEMNED THE RACES TO A TERRIBLE FATE; ON THE HOOVES OF WHITE NIGHTMARE AND DARK MOON”

Luna walked backwards scared. Celestia, Twilight and Pip just stared at the white ponies; fear was bursting in their eyes. Celestia finally managed to mumble something:

“Windigos”

The spirits stood indifferent but the older one just shrugged.

“They’re already sentenced to death penalty” he said with normal voice. “Just give them to us, this should be done in order to correct our mistakes of the past”

Twilight began to cry:

“Please, don’t ask us such thing! You’re supposed to be the Guardians of Harmony! You shouldn’t ask such horrible things as death penalty! Please, nopony deserves death penalty no matter what they did! Please you can’t do this!”

The older Windigo stared at Twilight, making her tears to froze immediately. The cold increased by seconds.

“Shut the fuck off, Twilight Sparkle. You chose to not to believe King Flames, even if the horrors he described were completely truth. I wish he was exaggerating but someone who lived the horrors of that time could never add more to the actual thing. But it was all truth: the carnages, the massacres; even that time they mercilessly slaughtered the original Bearers of the Elements of Harmony and plant a tree where the rotting corpses were fertilizing the soil. All those horrors were part of our history, so even you who are their family have to admit those monsters deserve the death penalty and much more. Flames’ mercy were admirable in its time; but now it proved to be a mistake. You freed the murderers, and if it’s true you never knew why they were locked; that doesn’t mean we’ll let things go just like that. Again: you know that they deserve much more than death penalty”

“No, you’re mistaken!” yelled Pip. “I, I, I’ve living with them for a few and I can assure you, they’re great ponies! They’ll never…”

The door opened letting pass the Old Generals, White Nightmare seemed very delighted with the visit; Dark Moon seemed more annoyed than anything. White Nightmare chuckled happily:

“Ey Dark Moon, look: the poor little cowards decided to show after so many years! Is kind of cute, don’t you think?” Mocked the white unicorn.

Dark Moon didn’t seem that aroused.

“Look at them: they come here to poison our little daughters’ mind with their lies. We’re not monsters, we’re warriors; nopony deserves the death penalty, and much more less to be defamed like that. I know we had our disagreements but still, you have no right to tell our daughters such things about us; you should be ashamed of yourself”

The older windigo glared at them:

“It’s a true disgust to meet you again, White Nightmare and Dark Moon. But I don’t care what you think about your punishment, you can’t avoid it; you should prepare yourself and…”

White Nightmare caught the spirit with her horn; immobilizing the windigo with her monstrous power. He tried to escape and run away but the General was too strong. The other ones ran to help their brother but Dark Moon extended his wings as a warning, forcing them to stop.
White Nightmare just stared to the winter spirit:

“You can’t come here saying you want to kill me and expect that I won’t defend myself. Anyway, what can you win tormenting my beloved daughters with that stories? Oh, I remember now: you feed from discord and hate; you plan to destroy Equestria but you know you can’t defeat us so you decided to put our daughters against us”

Twilight nodded:

“It’s true, IT’S TRUE!”

One by one the Monarchs walked to the Windigos.

“I don’t know what are you planning, but I’ll protect my Kingdom no matter what. I don’t care what I have to do to protect my little ponies; but sill you can’t separate my parents now than after all this years I reunited with them. You are disgusting” said Celestia.

Luna joined:

“Guardians of harmony and peace, you say? I don’t care what kind of lies Flames told Twilight Sparkle; but nopony here will believe you”

“Your story have no sense” added Pip.

The Old Generals smiled proud of their family; but then one of the Royal Guards attacked White Nightmare with a powerful green light beam. The impact sent the white unicorn against a wall, creating a few cracks on it. She screamed in wrath while the guard who attacked her helped the windigo to stand.
The guard turned into Chrysalis.

“You still owe us for your cowardly, but still, you have to start with something”

The windigo smiled.

“You came” he said weakly.

“And she’s not alone” said another of the Guards, turning into Discord. “It’s over, monsters”

“Stop it Discord!” Shouted Celestia. “You can’t convince us to believe than our parents are monsters! They’re great ponies! They’re our family, they’re…”

Chrysalis walked to them:

“Luna, Celestia, I don’t fucking care who; just, look into my memories. I’ll open you the door, just let me show you why I hate ponies so much”

The Princesses exchanged a concern look but nodded and Celestia walked to her enemy, with her horn glowing. Dark Moon spotted this but Discord stopped the pony.

“Chrysalis is volunteering herself for one of the most invasive spells of all time, so why do you want to stop her? Unless she have something you don’t want them to see”

The General was about to say something but his elder daughter already began. White Nightmare shivered:

“Please don’t…”

Too late, before them the images began to form showing Chrysalis’ past, especially the day when her hive was invaded by the ponies:

The changeling were nomad people, something that kept them safe for a very long time; but one day the warrior race came to the main hive, the one where the Royal Family lived:

The ponies arrived and walked through the hive killing every changeling they spotted; since babies to adults, all exterminated by the ponies. It was when the army arrived where the Royal Family lived.

A young changeling queen protected how they could to the little Chrysalis. All the soldiers walked apart, letting pass the leaders of the army: the Old Generals White Nightmare and Dark Moon. Dark Moon laughed with cruelty.

“So we arrived the heart of the changeling people: Queen and Princess”

White Nightmare relished.

“Tell me, Dark Moon, when you see a scene as beautiful as this you don’t want to… destroy it?”

The Pegasus nodded.

“It’s my turn, remember?”

“As you wish, but the Princess is mine” said White Nightmare.

And before the Queen could react, Dark Moon took her by the neck and then, she decapitated her. The little Chrysalis began to cry full of fear, but before she could run, White Nightmare caught her with her magic.

“What’s wrong little Princess? Do you miss mommy? Don’t be afraid, you’ll see her again in no time”

Chrysalis keep crying, irritating White Nightmare that made her send powerful lightings against the little girl; who began scream in agony. After five minutes of torture, the sadistic unicorn finally freed the Changeling Princess.

“What’s your name?” Asked White Nightmare.

“Chrysalis” mumbled the changeling.

Said that, White Nightmare made appear a spade in front of Chrysalis.

“Crissy: you’ll dig two tombs: one for mommy… and one for you”

She was about to cry again, but the sadistic unicorn made her horn glow as a warning; and the little girl obeyed, burying her own mother at the laughs of the murderers.

“Look at the bright side” smiled Dark Moon, “We’ll save you the bother to fill this tomb”

Then, an explosion of power sent away the monsters. A young Discord appeared and took the young Chrysalis in arms.

“Lord of Chaos!”

“You won’t die like this, little girl. Your race needs a ruler, someone who guide them against the Empire”

And before the monsters could react, they disappeared before they could do something.

Celestia freed Chrysalis, who were crying, whining in her anger. An awkward silence reminded, interrupted only by Celestia and Luna’s sobs; trying to get away from their own parents.
White Nightmare tried to approach but her daughters were too afraid of her.

“It’s, it’s, it’s all a lie!” Shouted Nightmare. “Come on, you know me, I’m mommy!”

Still nothing, they were crying in fear.
White Nightmare felt like her own world were demolishing around her.

“No, please don’t believe them!” Shouted again White; but her husband put a hoof on her shoulder.

“Dark?”

“Just stop it” he said calmly. “It’s done, they exposed our true nature to our daughters and there’s no way back. Harmony? Peace? Kindness? Friendship? They’re the same kind of people we used to kill just for fun; so since the beginning we both knew this isn’t our place”

White Nightmare finally nodded and turned to the windigos.

“Excellent move, now our daughters see us as monsters; and all because Flames took us away from them. If only we they were raised by us, they would see us as heroes; their role models; not the abominations they think we are”

Then, she created an ax covered in fire that ripped in two the nearest windigo; killing him instantly. The other ones prepared for battle but she just shrugged, approaching to a window.

“And this stupid were lucky. Listen to me carefully: you who exposed us to our daughters, we’ll kill you all; but not like this one, no, slowly and painfully; and your suffering will increase so much, than you’ll beg us for your death”

“And since we’re such good ponies, we’ll grant your wish” completed Dark Moon.

Said that, the white unicorn teleported away while Dark Moon flew through the window, but before he left, he turned to his daughters:

“We’re monsters and we admit it; but believe us when we say we love you more than anything. Still, if you try something stupid like trying to stop us, we’ll have to hurt you badly. But don’t take this wrong, you’re the perfect monarchs for times of peace. Just, don’t follow us, please”

And he flew again.
Everypony in the room were shocked, leaving the room in deep silence; but then the Princesses began to cry. Daughters of murderers, daughters of the monsters.
