Author's Note

well, the chapter was too big, I thought about separating but I'm too lazy to create another name for the title so this is it, a chapter of 2,8k words, God I thought it would have a maximum of 1.5k.
maybe I will remove some things, I still don't know if this chapter explains too much

Memories of the past: Last day of Crystal Empire

Today ... Today may be the last day of my beautiful kingdom, I look from the balcony, admiring the crystalline buildings that rise through the city below and the castle, really, a beautiful view, if you ignore the monster outside the empire, there, at the top of a hill is a monster, the worst being that has ever crawled across the planet, a human, wearing the horns of countless warriors who tried to stop him and failed, adorning himself with feathers like trophies on his head, and mane strands are being used for decorative purposes, this thing is coming, and with it comes your army, countless ponies, griffins and whatever has entered your path constitute that army, controlled by a nefarious device that clouds the mind, and numbs the senses , if we had another week ... Just one, we would have found a way to break the spell, but now it’s too late, Sombra and his army couldn’t stop the human, now he’s at the door of my kingdom and the Crystal Heart can't maintain the shield up for more than a couple of hours, when the shield falls, the Cristal Empire will fall with him ... Do not delude me like my aunt Luna, who still believes in victory ... Luna, she wanted to die in a glorious fight against this monster beside her sister than to have come to the empire, but now she is here, and the look she faces the human is, for want of a better word, is creepy.

"Mom ... I'm scared." my daughter, Flurry Heart, a mare already, heaven ... Tomorrow she would be eighteen, now I don't know if we will pass today.

"Calm down dear, go to your room, mom and aunt Luna are discussing important things here."

"I don't want to! I know something is wrong! Uncle Sombra has disappeared! And Dad doesn't even look me in the eye anymore, he just trains the soldiers!"

Shining ... Really? "He is very busy with his work, but tomorrow ... Tomorrow he will have all the time in the world to play with you ok? We might even see Aunt Celestia! What do you think?"

I feel the furious look that Luna sends me, but I ignore it, not now Luna "Aunt Celestia? Is she okay? She doesn't answer my letters anymore ..."

"She is ok, dear now, please go to your room, Mom is having an important meeting here."

"OK..."

When I hear the door close let out a sigh, she can't know ... Never ... Damn Sombra why did you go alone to face that monster ?! You would have been a great help now ... Damn ... Who am I fooling, he got us two days and we didn’t take advantage of that time.

"You shouldn't lie to her Cadence ... She has to know."

"Know? Know what? That today is probably the last day of her life? That we are the last country of ponies that exists? That has no help coming from? That all the elements, Celestia and Discord are dead?!?!? Tell me Luna! Why I still don't know which one to choose !!! "

"I ... Look Candence, she has to know, not because it will be her last day, but because it will be the biggest day of her life, the day when we, the last alicorn, will defeat that monster, and rebuild Equestria ! "

"Stop lying to yourself Luna! We lost, he won ... We are outnumbered twelve to one, there is no victory, when that shield falls, we fall with him."

"If you want to keep thinking about it I don't care, what matters is, are you going to sit here and die? Let that beast kill your daughter? Because he knows who she is, and he knows that you are here, he will make a point of kill her right in front of you Cadence, will you allow it ?, will you allow your husband Shining Armor to die in vain? She is there, preparing the soldiers the best he can, and he will not hide, he will fight Cadence, What will you do? Will you fight beside him or will you hide here? "

I feel a whirlwind of emotions, anger, shame, fear, and ... There in the middle of this whirlwind, I feel something I haven't felt for months ... Hope.

-------------------------------------------------- ----------------- // ------------------------------- --------------------------------------------

Eleven hours ago I lowered the moon, Cadence believed that was my last sight of the moon, silly mare, there will be countless nights yet to come! I will do today, the most beautiful of the nights, after defeating this monster in human skin, I, PRINCESS LUNA SHOTING STAR, WILL DO THE BEST OF NIGHTS! IN HONOR TO ALL THOSE WHO HAVE FALLEN AGAINST THIS DEMON, IN HONOR OF MY SISTER, IN HONOR TO THE ELEMENTS, IN HONOR OF EQUESTRIA !!!

I feel a smile of pride forming, I look at my armor, with plates of the purest steel, blue as the bluest sea, and protective runes everywhere, on my left is my spear, with light details that I made myself, referring to all my history, from my rise, until my fall as Nighmare Moon and my return to Equestria, and on my right, this is my sister's sword and shield, this sword and her shield were all her personal guards they managed to recover, I will carry these weapons with pride, because while I use them, I know that my sister still watched over me, guided me, and helped me to kill that monster! I hear Cadence flying beside me, tears in his eyes, "it seems that you decided to accompany me in this fight Cadence."
"Let's get this over with Luna, together!"

When his words were spoken we didn’t see, a river of fire coming out of that little hill, the whole shield was engulfed by flames as yellow as the sun that watches over us, and this incessant river continued for countless minutes until it stopped abruptly, all of us, soldiers, captains and princesses, we saw with a slight fear the shield fall.

"SOLDIERS OF EQUIS, TODAY WE DO NOT FACE A SIMPLE MONSTER, TODAY WE FACE THE BUTCHER OF OUR SPECIES, TODAY WE FACE A DEMON THAT IS NOT LOOKING FOR ANYTHING MORE THAN DESTRUCTING US, TODAY MY FAITHFUL SUBJECTS, WILL WE WIN THAT BEAST THAT COMES AT OUR GATE, OUR HOME! THREATENS US WITH HIS ARMY! SO? WHO'S WITH ME !!! "

"WEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!"

It begins.

-------------------------------------------------- ----------------- // ------------------------------- --------------------------------------------

I am the High-Captain of Equestria, king of the Crystal Empire, and one of the greatest fighters of the war against the Griffin Federation, and even so, all these titles are worth nothing, medals are not taking up arms and going to face our enemies, no are helping the wounded or shooting arrows at the human, no, titles are useless, now I’m just another soldier in the middle of this sea of swords, spears and arrows that has become the central gate of the city, in the heavens, the few pegasus that escaped from Equestria and managed to get here are facing the ... Candence calls them shells, Shadow called them plans of the past, these soulless beings, these ... Shells, are innumerable, each pegasus has to deal with more than four of them to we have a chance to win the fight in the sky, the fight here on earth on the other hoof... If it weren't for the considerably slow response time and the fact that we are funneling them we would have already been slaughtered, however the rivers and rivers of ponies that come don't stop, griffins fall from the skies, snatching the poor soldiers and taking them to the skies, they never come back ... Or fall,

"RETREAT! MAKE A DEFENSIVE LINE NEAR RESIDENTIAL NEIGHBORHOODS!"

Every step taken back means more of these shells within the empire, and the explosions in the sky do not indicate that things are going well, Luna and Cadence are going to face the human and I haven’t seen them for almost half an hour, their only sign of life is the color of the clouds, which sometimes turns blue, sometimes yellow and even black, the only signs that a fight is on, that there is still hope!

Then, a crash, so loud that even the shells stopped what they were doing and looked at the skies, almost like a truce, and we saw ourselves, falling from the sky a dark blue figure, flames coming out of it. "No..."

Everyone knows what it is, who she is, I can see the fear in the eyes of the few ponies of Equestria, and the despair in the crystal ponies, "FIRM, KEEP THE POSITION, DON'T STAND BACK, KEEP FIRM !!!"

Reinvigorated by the almost desperate words I shouted, they maintain their position, they have to maintain, because if these shells pass through us, there will be nothing between them and our families in the castle.

I release a magic missile, another one sending several ponies flying, but their places are quickly filled with new ones, they are countless, so I see, a big minotaur running towards us, I try to stop with missiles or shields, but he ignores them, even the holes in his chest did not stop him from hitting our shield wall, it was a disaster, several died, several were paralyzed, but our enemies didn’t, they continued, and in less than a minute our defensive line was gone, "RETREAT TO THE CASTLE! LOCK IT! "

"Captain and you?"

"I'm going to get Cadence and I'm going, I want a circular shield wall, understood ?!

"Y-y-yes captain!"

With that I teleport to the highest tower in the city, and I see, Cadence being chased by that monster, with a snap of fingers he creates huge fireballs and throws them at my wife while laugh insanely, I create a shield as fast as I can , stopping those black flames from reaching her

"RUN CADENCE! I'LL KEEP HIM BUSY!"

"NO, HE WILL END YOU!"

"I WILL BE OK, WHEN IT FINISHES HERE I WILL RUN TO THE PALACE!"

"SHINING I--"

"DAMN CADENCE LEAVE NOW!"

I feel one more of the fireballs hitting my shield, I also see it cracking and breaking, and there in the sky, a few centimeters from the shattered shield, was Cadence, tears welling up in her eyes as she mouthed an inaudible word, and with a pop , she disappears, ok ... She is safe now ... I feel the mana of my horn cool down, however, I am removed from my trance by a fireball, I cannot let them pass, the castle gates are being pushed, in seconds they fell! Ok Shining, it's time to shine.

I put everything I have, countless shields appear in the skies, preventing rains of fireballs that come out of the clouds, trapping everything that flies away of the castle, covering every window and stained glass, and covering the castle gate, even if only a few seconds, I'll give them those seconds! "NO ONE WILL PASS!"

With each fireball one of the various shields falls apart, and he is aiming at me, every second has less shields around me, but I cannot run now, I cannot retreat, I have to protect the castle I have to protect Cadence I have to pro---

BOOOOM!!!

I feel a colossal pain, when I realize I'm falling, falling from the tower, I see the place I was, destroyed by a magic missile, I feel a cold run through my body before looking at the floor, sorry dear, I wiil not be able to get there...

Ahhh, satisfaction, there is no better word to describe this moment, Luna gave a hell of a job to kill, but who knew she would freeze when she saw Celestia's horn? And without Luna helping her, Cadence was an easy target, until that unicorn got in the way, boring guy, full of shields, but one hour he ran out of shields, then it was just waiting for the right time and BAM! He was gone, he has potential, then I take his horn and Luna's horn, now it's time to play!

-------------------------------------------------- ----------------- // ------------------------------- --------------------------------------------

"Cadence where are youuuu?"

I stop in front of a door with the Crystal Heart symbol and smile, add all the strength that my body allows and kick the door, the hinges give way and fly out and inside, she was, Princess Mi Amore Cadenza and her daughter , this will be a glorious fight! I can already feel the adrenaline ---

"No, please no..."

"What?"

"Please ... Not in front of my daughter ..."

She was crying, CRYING, where was that warrior spirit? That desire to kill me? Did it die with Luna? Perhaps.

"Mom..."

"Shhh dear, everything will be okay ok? Mom take care of that."

With that she gives a kiss on the daughter's forehead, and she passes out, a sleep spell, cowardly, boring, but extremely effective.

"(sniff) can we leave her room at least?"

"Why should I? Actually, why shouldn't I kill you now?"

"From a mother to a father."

I feel my heart racing, how does she know that? Maybe ... No, Celestia would never say that, and Luna is not the most talkative of all, so how?

"You have ten seconds to explain yourself, how do you know that? If not, i'll blow up this castle!"

"I can see the soul of somepony Spencer , looking into eyes, and your eyes tell me that you have a daughter."

"..."

"Please."

"OK."

Why am i leaving the room? Only they are missing! They are the last targets on my list! Damn why? I don't detect any spells, so why? Why do I feel my eyes moisten, why do I feel my heart racing? I leave the room and walk to a corner and wait, I see her leave and different from what I thought, she stayed there closed the door and remained still.

"Has ... Is there any chance that you won't kill her? I do anything, I cast any spell and I give you my horn, I tell you where Celestia kept her personal file, where Luna keeps her weapons I ---"

"I want a way to go home."

"I ... I can't do this ... No one can."

"I know, but I'll find a way, even if I go to all the great libraries in the world!"

"Are you afraid ... Why?

"Am I scared? Cadence, I invaded your kingdom and my soldiers are all coming to your precious castle, I don't think I'm the one scared!"

"You are afraid ... To come home, afraid that they fear what you have become."

"WHAT DID YOU MAKE ME!!!"

"Spencer, nobody knew, I mean, do you really think we would allow that?"

"You allowed it, now i'm here, and you're living too much for someone so insignificant."

"Spencer, I know you're angry, but my daughter was very young, she had no way of knowing! I beg of you, just as I still see goodness in your heart, please spare her !!!"

"You talk too much Cadence."

I take a horn from my coat, it's is a white horn that I got from one of the Canterlot nobles, my second best magic missile horn, she doesn't even deserve the expense of the other horn.

She seems to understand the message and points the horn at me, let's finish this, I saw the lightning coming towards me, it was just a matter of deflecting and shooting the missile, it hit her in the chest, she flew a few meters and entered the wall.

I walk as slowly as I can, with heavy steps, I know she is alive, alicorn are difficult to kill, and that is the best part!

"P-p-please, spare her, I beg you ..."

"Where were you while i begged?"

Done, a missile right in the face, she was dead, the target now is her daughter, I open the door and there she is, calm serene in her bed, so many things were going through my head, would this be the fight I would have with her? Killing a child while sleeping is not my thing, but doing what, I put the same horn that I used a little bit against her head and ... And ... Why am I hesitating? It’s just letting go of the mana, and it’s over, I ended my revenge, but why? Why the fuck can't i kill her?

"Mr Spenceeeeeeer, what do you think you are doing with my niece?"

"Damn it."

"And better not to do that!"

I let out a sigh, obviously it was not compassion or something, I would never feel it for these ponies, it had to be her, I take a small pill in my coat, is the last one? How the universe has a sense of humor.
I swallow the pill, I hear that demon scream something, but it doesn't matter, it's gone, I can feel the effects starting, some things are already changing color, everything seems to happen faster, background screaming noises become bigger, and hesitation gone.

Psfuu

She is dead, my vengeance is complete, all of them dead, each of them, and why, now, after all this ... I feel nothing but ... JOY !!!
