The darkness was clouding the alicorn's disturbed mind, the increasing night didn't help a lot to clear her troubled mind, she ran as fast as she could in a damned place that had previously been known as the Crystal Empire, she never stopped to see each side while she was running, worried to see one of those damn monsters that destroyed her world, turning it into a fiery rock lifeless, the fear she felt was big, are few the times she had to do this things alone, but she hadn't choice, those monsters discovered their hiding place, yet with hurt in her heart, she saw herself, remembering as her eyes watered, as she saw her last friends sacrificing themselves for her, trusting in Twilight, hoping she'll give a best world for all... there couldn't be any mistake in this mission, this could be the salvation of what's left of her people, has passed a lot since she left the Everfree Forest, the place where she lived her last years, after walking some time in the ruined city, she reached to her destination, cautiously she stopped front the Crystal Palace, wasn't very difficult to enter in, after all the great door had been demolished ago long, the day when the demons came to this innocent world... once inside, she tried to remember where was the room she was seeking, she started walking trying to make as lesser noise as possible, sunken in her thoughts she realized that their hooves trod something, she looked down and saw something she hadn't seen long ago, a Canterlot guard's helmet, half melted by the green flames.
Twilight at that time had little flashbacks of that tragic day, was raining fire from heaven, whose beautiful blue color change to a depressing gray, ponies were running desperately through the streets, the whole atmosphere was flooded with cries of despair and agony... the royal army tried unsuccessfully to repel the invasion, is little to say that they failed front the power of the legion, Equestria was defeated in question of hours, and with this, the death of millions of ponies, and... the death of the symbol of hope of this earth, the light of each day, the reason that there was one day... very few were alive after the death of Princess Celestia, the few survivors were trying to live each day in a hell for years, hell which before could be called paradise, a peaceful world among many who fell victim to this hideous demonic force, but, the last one alicorn who continues alive in this world, Twilight Sparkle found something that could change the course of the world, in the Canterlot library, which had remained inaccessible since the fall of the capital, fortunately she could recover it a few days after that defeat... and before the corruption of Canterlot.
In the book of the most powerfull spells of Starswirl the bearded, she found an enchantment, which is able to transform the magic mirror of the Crystal Palace in a black hole, which would be able to take any being to any dimension, planet or even time choosen, in the middle of the walk around the palace, she didn't notice she passed next to a small imp, a small and black demon, with the seeming of a goblin, who began to see her with malice, then, the small demon placed his fingers on his head.
"Lord Vanezz, I found the alicorn" After saying that, the little demon retired his hands from his head, he started laughing hideously.
"Ah?" Twilight turned around in a defensive position, that creepy laughter couldn't be clearer.
"Show yourself, damn coward!" She hadn't any answer, then realized she has done a terrible mistake, she hoped no one have heard her, thought as she tapped her mouth with her hoofs, after seeing each side one more time, she continued his way until she ran into a door...is this, this is the room she was looking for.
Twilight Sparkle opened with difficulty the great door, after doing so she felt a cloud of dust lifted by the passage of the years, after the dust cleared, she walked to a covered huge figure with a blanket, using her magic she removed the blanket, revealing the mirror, the key to their salvation, once she contemplate the mirror, she sack of his black coat a picture of her with her five friends, is among her most valuable properties, in it, they all were in a group hug, and Pinkie had the idea to take a photo, she remembered that day as if it were yesterday, as if she really had lived it...she started to fell nostalgic, anger, sadness, frustration... but when she felt a tear falling from her eye was decided, firmly she keept her picture on her coat and went to the mirror.
"In your memoirs, I promise I won't defraud you, no this time" Then the alicorn began to conjure a spell which apparently was draining her energy quickly, after her horn shot a ray of light, and crashed into the mirror, it first began slowly to deform it, later it began to emit strange energies, but she started feeling than the spell was turning more difficult to control than she expected, black energies began to spread, as she was trying keep the control in the spell, the mirror frame started to disintegrate, and unexpectedly, a little and dark explosion happened, she saw herself obligated to close her eyes, cause despite the explosion can't do any damage, it could temporally blind her eyes, when she reopened her eyes she saw it, now, instead of the mirror, there is now a purely black oval, that strange portal created by Starswirl, and now opened by Twilight, gives the hallucination than in where is the portal, someone had cut a piece of the same universe, and left only one black oval space.
"It... It worked!" Twilight felt a great happiness, she didn't felt nothing similar in years, now more optimistic, she began to channeling a spell to determine the coordinates of the portal, the portal was working how had described Starswirl, but tragically in middle of her happiness, she felt a burn on her ear, the pain was unbearable, but the spell was complete, it wasn't the place she wanted, but that portal would lead to an unknown location.
"AAAAAAAAAAAAHHHHHHH!" Twilight fell, the pain the pain began to decrease slowly, but instantly she recognized that kind of magic, for her bad luck, behind her was standing her worst nightmare, responsible for the destruction of their world, and the agony of her friends... responsible for his misfortune, this demon is much more powerful than the others, his skin has a pale tone, has coldly black eyes as his mouth, hoofs instead of feet, big horns on his head, giant wings like a bat on his back, and wears an armor of a green hue, adorned with skulls, this demon began to walk to Twilight slowly with a smile on his black mouth .
"Hahaha, what happens, princess? Did you have planned to escape? And leave all us here alone? That offends us little pony" Vanezz said stroking the cheeks of Twilight, who felt an enormous anger at that time to the nathrezim, at this time all she wanted was to have the power to annihilate those...
"I see you've been playing with magic, haha" Said his companion, Derzanor a pit lord, who came out of the shadows, the pit lord is an unpleasant being, is huge, it's like a centaur morbidly fat, has huge tusks sticking out of his face, and he, instead wore armor with a reddish hue, he said this when he saw the mini black hole that Twilight created.
"And I see than Vanezz brought his pet"
"Grrrrr, How dare you?!" Derzanor was about to slap Twilight with his huge hands but was stopped by an even smaller hand.
"Isn't yet time for that, my friend, we yet have a question for her... what's that?" The nathrezim said gravely pointing to the portal.
"What do you care? You said long time ago than our magic is pathetic and..."
"I care because if you don't know, you're in territory of the Legion , and you're doing magic without permission in our territory , we will not allow any... "
"Your territory?! Am I invading your territory? YOU AND YOUR STUPID LEGION INVADED AND RUINED OUR WORLD, OUR HOME!..." Twilight tried to avoid the tears, in seconds those two stupids started laughing, for the eyes of both demons she just is an inferior being, she is aware of that. "What gives to you the right to destroy innocent worlds? Why do we deserve this?"
"Please, do you think that your world had at least a chance to fight with us? Just look!" When Derzanor said this, Vanezz teleported to the three outside the Palace, a vile and dark magic surrounded them, Twilight was dizzy for the magic, when she realized was out in the courtyard of the Palace saw it, hundreds of demons acclaiming to the Nathrezim and the Lord of the Pit, they all shouted in an unknown tongue, many with a shrill voice how imps, while others (the biggest) with a serious and intimidating voice, like Eredars and include some Infernals, Twilight sadly saw some (demons), which long ago were like her, trying to don't be distracted by their feelings, she saw his chance, if these were all the demons on Equis, and if Vanezz and Derzanor forgot her black hole... maybe it was time to carry out the plan C.
"You just look, we are only a few hundred! A small part of the Legion was more than enough to destroy this filthy world, CONTEMPLATE THE POWER OF THE LEGION!" Derzanor in the middle of his speech collared the Alicorn "Only a few intelligent ponies accepted our offer and joined to us, and now, very soon we will end up here, THIS PUNY PONY IS GOING TO BE THE PERFECT SACRIFICE FOR OUR DEMONIC LORDS!"
Twilight has to act now, in a second she teleported herself out of the reach of demons, in one of the Palace balconies.
"So you are all in here..." Twilight said, her horn began to shine.
"WHAT THE HELL DO YOU THINK ARE YOU DOING THERE!?" Derzanor cried enraged, suddenly, a magical aura was drawed on the ground where the demons were, the aura began to shine. "GRRRR" The pit lord was ready to charge to the alicorn, but his superior smaller stopped him, putting his arm in front of him.
"Bring her" Vanezz said firmly, soon five Felhunters, which have the appearance of a deformed dog, began to climb where it was Twilight.
"You should never underestimate us" Twilight felt even more courage, the demons were getting closer of her, but she didn't pay much attention to them.
"Her horn is shining" Dernazor began to suspect than something was wrong.
"You yourself saw their magic, it can't cause us a high damage" Vanezz answered very trusted
"I told you... never underestimate our power" Her horn then issued a wave of purple light, which got a long distance, and happened quickly what she expected, the felhunters sent by Vanezz arrived to Twilight, but before they could touch her with its claws, an invicible force, like gravity attracted them inside the palace, like the other hundreds of demons, who began to make even more unpleasant noises, trying to escape the invicible force.
"It worked too..." Twilight began to run back to the room where the portal was.
"What the hell is happening!?" Derzanor cried amid the chaos, hundreds of demons were being drawn like a magnet to the Crystal Palace, lot of them, colliding with walls of the Palace.
Twilight knew the portal would teleport the demons to somewhere in the past, but it won't teleport those wretches to Equis, she hadn't managed to finish the spell, she just hoped than wherever they will stop, it won't be a place with life, she came quickly to the room where the portal was and saw it.
In a second all demon present, even a powerfull infernals began to be swallowed by the portal, it was like watching a swarm of giant flies around yourself, unfortunately she didn't realize than the portal, or rather black hole was becoming more and more bigger.
"WHAT'S HAPPENING, WHAT DID YOU DO STUPID PONY?!" Vanezz cried seeing the alicorn, the Dreadlord was running quickly, trying to don't be eaten by the portal, next to him flew a huge pit lord, this was heading at high speed to the portal.
"AAAAAAAAAAHHH" Having cried this, the huge pit lord was sucked into the portal, among the few demons that remained was Vanezz.
"YOU, you'll pay for this" The Natrezhim cried to the Alicorn, who slowly approached him.
"First, I think you need a boost" Followed, Twilight shot from her horn a large beam to the demon,rather than do hurt, it only scattered the Dreadlord, and he was quickly absorbed by the portal, Twilight barely noticed what happened to the portal, now she saw how the portal was tearing the same space time, this was one of the warnings gave Starswirl, never leave alone the portal.
"It's becoming unstable..." When she was going to do something with the portal, happened another dark explosion in the room, stronger than the first, she was forced to close his eyes, it was so dark that caused pain in her eyes, after passing some seconds, she opened them again.
"...It's over?" She said softly, without idea of what she had done, she soon found where the portal was, it had disappeared, leaving nothing.
"What... what happened!?" Had happened something totally illogical, before her eyes she watched how the portal was devouring itself, she was shocked, in a second, all those responsible for the destruction of his world disappeared, with the portal disappeared, and she hadn't idea where they are now.
But... she haven't idea of what she has done.
