Last night
In Luna’s quarters, the princess of the night uses her power to lift the moon. As she does, her sister Celestia lowers the sun at her own bedroom. They do this so together so neither would strain their bodies doing this task. However Celestia had to do this ritual alone for the past thousand years and it has weakened her body and soul. Though her appearance hasn’t changed for a thousand years, only those such as Alicorns or Powerful unicorns can see how diminished her once bright soul has become.
It hurts Luna both physically and mentally seeing her eldest sister so unwell. Hearing that she lost to Chrysalis just paints a picture of how weak Celestia has become. She used to be able to deal with these types of villains by herself, she used to take down armies with but one stroke from her weapon, she used to take on god like beings such as Discord or Tirek. Now she'll be lucky if she could lift a mountain.
Stars begin to fill the sky and the great rift can be seen tearing the night sky, an abhorrent sight that ruins the natural beauty of the stars. And every time Luna even catches a small glimpse of the rift, laughter fills her head. Evil daemonic laughter that constantly mocks her, it only lasts for a short time, but the laughter always sends shivers down her spine. And the laughter will only ever get worse the more glimpses of the rift she sees.
However the laughter began to shift from her head, to her very room. There’s someone in her room. “Who’s there? Show yourself!” She demanded. Then the laughter suddenly stopped.
Six masked figures male and female wearing brightly coloured skin tight clothes come out the shadows. One from the corner of her eye, another uncurls from the ceiling, two place their hands on Luna’s shoulders giving her a fright. Another cartwheels out of the closet, boops Luna on the snout and giggles. And Finally the last figure jumps down right in front of her this one was wearing a bright coloured trench coat and the mask had a wide devilish grin. “Princess of the Night, it is about time we had a little chat.” Said the leader of the group.
“Who are you? And what do you want?” Luna asked.
“Oh where are my manners.” He bows to the princess and introduced himself. “I am Troupe master Diac-Vann. And we are the Harlequins. We’re here to protect you”
“I assure you uh, Clown. I don’t need your protection.” They all chuckle at Luna’s comment.
“There’s no doubt about your abilities Princess, but even you with all your power, cannot face a Solitaire.”
“ A what?” She asks. Diac-Vann points to the balcony, There Luna spots two People standing there. One is a horned hooded figure, staring at the great rift in the night sky. Insulting what ever dark creatures reside there just for existing. Luna can feel this creatures evil, she can also see that it has no soul what's so ever. The other is the mage that showed her the prophecy waiting for her to come forth, she looks very patient.
“Just interacting with the Solitaires is a bad omen. And they rarely speak outside of performances, so speak with him quickly.” Diac-Vann warns the Princess. And before Luna moved to her balcony Diac-Vann added to his waning. “And don’t try pushing him off the building, The last mon-keigh who did that got his head crushed by him three seconds later.”
Luna took a deep breath and walked to the balcony, she stood right next to the Solitaire. His horned mask has a blank expression unlike the others, he just continues staring at the great rift as he speaks. “The Dathedian.”
Luna and the other Harlequins flinch, except for the mage. “Excuse me?” Luna bravely responds.
The Solitaire explains. “There are many names for The Dathedian. The Imperium calls it the Cicatrix Maledictum, The Orks crudely call it Gorks Grin, whereas the Leagues of Votann give it no name in fear of feeding it power. But your kind, like so many other species in the galaxy call it the Great Rift.”
“What does this have to do with the Prophecy?” Luna Asks with impatience in her tone.
“The forces of Chaos has poked its way in the prophecy without our knowledge.” The Mage joined the conversation. “If we don’t act now everything we have done may be all for nothing.”
“So now you don’t speak in riddles Mage.” Luna Scorns the mage.
“I am Shadowseer Nea-Yryr. And forgive me for what I did during our first meeting, I only did so to put you on the right path.” She apologises to the Princess. “But now your world, and our plans are in immediate danger.”
“What do you mean?” Luna Questions.
“Sombra. Is here.” The Solitaire answers. “An Astartes that’s been alive since before the event known as the Horus Heresy. A deadly seer who can cause Daemons to posses the bodies of any living creature. A man so twisted, he'll stop at nothing to get what he wants.”
“He seeks the same thing you do. And if he gets his hands on it, he will summon a warp storm to consume your world and your people will be forever damned by the ruinous powers.” Nea-Yryr added.
“Then I will Stop him.” Luna Said to them.
The Harlequin troupe laughed at what she just said, yet The Solitaire doesn't even chuckle. “Many have tried to kill Sombra, Even his own men tried to kill him. But all attempts were in vain.” The Solitaire explains.
“Then what should I do? I can’t just let him destroy my world, so that he can gain more power.” Luna asks.
“No you shouldn’t, The Phoenix lord has returned yes? Find the one named Twilight Sparkle and speak with Asurmen.” The Solitaire suggests. “And no matter what, get them to wear the armour.”
“And if we fail?” Luna asks.
The Solitaire pauses, his demeanour has changed from some form of calm, to a more sorrowed one. “Show her everything.” The Solitaire orders the Shadowseer. She quickly placed her hand on Luna’s forehead plaquing her mind with the horrors of what chaos can do. Entire worlds corrupted by mutation, bloodshed, disease and pain. Powerful warmongers brutalising innocent people in the name of their dark gods, children screaming with fear. And the laughter, that horrible laughter of thirsting gods, feeding of the misery and pain of mortals.
And then the visions shift to the past. Her past. In the the empty throne room of an abandoned fortress. The dark gods reach their hands out to Luna, telling her everything will be alright. She begs to herself, on her knees, shouting to herself not to accept their power, and yet she has no control over her body. And so she unwillingly accepts the power. And then suddenly she wakes up, her mind racing, breathing rapidly until she realises it was just a nightmare. A sight into her past, and a vision of what’s happening in the expansive galaxy.
The Harlequins are gone, they must’ve left during her vision. She should feel a sense of calm, yet what she saw herself do in that dream, What she did in the past, she regrets every waking moment of her immortal life. Her eyes started to water and Luna burst into a sobbing mess of emotion.
Then her bedroom door opened, a concerned Celestia slowly made her way to her little sister who is in tears and crying in the corner of her room on her knees. "Luna, are you okay?" Celestia asked as she got on the floor.
Luna didn't answer she just reached out to hug Celestia. This came to a surprise to Celestia since Luna was rarely the type who hugs. "Shh, I'm here now. I'm here." Celestia says in a calm soothing voice. "And I won't leave you, I promise I will never leave you again."
"Why?" Luna sobs. "Why won't you hate me? I hurt so many ponies, I hurt our friends, our family and most of all you. And you are suffering due to my selfishness. Why won't you hate me?"
Celestia strokes her sisters head and then she answers. "Because I learnt that hate gets you nowhere in life. And despite what you have done in the past, it does not mean you're the same pony that tried to bring Equestria into an eternity of night. You are my sister, and I love you."
Luna calmed down little by little. Her eyes began stopped the tears from flowing yet the sadness still resides in her heart. "Sister. Promise me you won't go."
"I won't." Said Celestia thinking nothing of it at first.
"No...I mean it." Said Luna. "Please don't overexert yourself anymore, let me help you. Let me take responsibility for my actions."
Celestia now understands. "Okay. I promise I won't go."
Present day
On the outskirts of the Crystal empire on top of the snowy mountains, Three members of the crystal guard climb the mountain to investigate recent sightings of an anomaly in the sky. The icy winds blast at their faces, their hands cold to the touch, they honestly cannot wait to get this over and done with, so that they can go home and get warm. They do have some protective gear, warm coats, gloves, hats, scarfs and goggles. And they even brought their own spears, just in case they run into anything dangerous. But even with all this gear they still feel the cold.
Soon the wind stops and the group was surrounded by thick fog, the snow drops float in the air as if all time has stopped. They look up and see a gigantic ship in the sky. Coloured black and trimmed with gold, the ship is covered with spikes and guns, armed to to the teeth and ready for war. “Warn the princess, the shields need to be raised.” The captain orders. one of guards ponies nods and quickly runs back to the kingdom.
“You look cold soldier.” A voice calls to the rest of the group. The two ponies raise their guard and point their spears in the direction of the voice. They see a heavily armoured creature sits on a rock right in front of them. It has black armour with gold trims and massive shoulder pauldrons, he has a red tattered robe over the armour, a horned skull for a helmet, leather gloves and a fiery staff with a symbol that has a creatures skull on fire and eight points. “Would you like to warm up?” it offers the two ponies.
“Who are you and what do you want?” The captain demands from the stranger.
“I am Sombra, and I only wish to tell you the truth.” Sombra’s words makes the ponies feel the chill even worse than before. He levitates towards to ponies and continues speaking. “What if I told you that reality as you know it is a lie? And that Gods are real?”
“I’d say you’re insane.” The captain starts shivering. His hands feel numb and he lets go of his spear, he cannot move, he cannot feel any warmth. “What’s happening?”
“I understand how you feel, I thought the gods weren’t real once. That was until my mind was opened, and when my father showed me the primordial truth of the galaxy.” Sombra preaches. The captain is absolutely freezing, his heart is racing yet it’s not warming his body. “You look cold soldier.” Sombra repeats himself. “Would you like to warm up?” The captain nods, unable to speak because of the cold. “All you have to do is hold my hand, and you’ll never have to suffer again.” Sombra tells him.
Every bone in the captains body is yelling. ‘don’t do it! It’s a trick!’ But it’s so unnaturally cold, maybe if he just touches it slightly, nothing bad would happen. So he takes hold of Sombra’s large hand. At first nothing happened, but then he started to feel warm again. However as his body temperature begins to rise he feels violated somehow.
And then he begins to puke out all the contents of his stomach, then once that was empty he spews out two litres of blood. Sombra laughs maniacally as the pony screams in pain. The captain right arm mutates into five purple tentacles with spikes, his torso turns into a large gaping maw and horns comes out of his eyes. His screams turn into a predatory screech. “Your suffering has ended xenos. Be glad you survived, for now.” Says Sombra. “And as for you.” He speaks to the other pony who’s frozen in fear. They try to make a run for it, but Sombra blasts a bolt of fire out of his hand, setting the poor soul ablaze. Sombra laughs as his entire Chaos Space marine army comes out of the fog and he says. “All hail king Sombra.”
