As Twilight Sparkle ran through the woods with her friends, trying to reach the castle of the two sisters, she wondered where the Elements of Harmony could be.

She needed to reach the castle, so they could find the elements, and stop Nightmare Moon. She skidded to a stop before a chasm, the rope bridge hanging. As Rainbow Dash flew across to tie up the bridge, and the attack by the fake Shadowbolts, she thought about how to go about finding them.

As they entered the pyramidal castle, they looked around. Unkowingly, one of the girls put her hoof on a stone slab, and as she moved on, it sunk down into the floor.

I awoke. The systems around my body, thawing me from the cryogenic sleep I had been put under.

I extended my senses, and the only thing in close proximity, was crystals, and a single egg. The crystal caves had been my home for the last three thousand years. No one, none but the last of the race of ponies who had settled this land before the tribes knew of me.

They had built the castle of the two sisters, that they had moved into. And they had built the systems that had kept me sleeping for three thousand years.

I heard footsteps approaching my chamber, and hiss.

"Who approaches my chambers?"

The last humanoid pony, given the form of a human by his parents, thanks to a spell that changes the DNA to that of a human. He comes into my senses.

"It is me, my Queen. I have come, because Nightmare Moon, has returned." I nod, and hiss.

"Thank you, for your sacrifice. Know, that your sacrifice will birth my race. And that, it will bring about the protection of Equestria." he nods, and then approaches the one egg in the room.

He kneels in front of it, as the egg opens. The insides shift, as my child moves around inside it. He starts to tremble, and I could not blame him. He was about to die.

The facehugger crawled out the egg, and crawled onto his face, sticking out its ovipositor into his mouth. It then hugged his face, and I could sense the lump going down his throat. As it finished disharching it's embryo into him, it detached, and the winded pony was breathing hard. He took a few minutes before he got up, but he finally did. As he turned to leave, he says.

"My Queen, it is an honor to serve you, and be the bearer of your children. I will go to the castle through the teleportation crystal, and destroy it. Then, I will await my fate. May your Hive live strong." And he walks over to a glowing blue crystal, one of only two on the planet, and touches it. He teleports away.

I sigh, and rejoice. My children will be revived again. A few seconds after the stallion human teleported out, an explosion happened to the crystal. It sent out shards, but none hit me or my egg, which had closed itself after releasing its facehugger. I now waited.

The stallion human appeared in the castle, as the girls were looking around. They had not reached the main chamber, which held the pedestals that bore the Elements of Harmony. He was In an adjacent room, built thousands of years ago for this day, and he waited for his end. Before he died though, he had one last duty. He took the last of his energy, and started to load it into the crystal. As he did, the crystal started to overload, and eventually, it explodes, shattering. He is thrown back, and is bloodied by the explosion. He coughs, and sits there.

After some time, he started to feel a tightness in his chest. He knew it would be soon. His breathing then became slightly labored, and the pain in his chest increased. He started to say goodbye, as suddenly his chest started to heave of its own accord. It bulged, and tore, until finally, it burst open, and he collapsed upon the ground, dead.

In the stallion humans chest, rising out of it, was a single chest burster alien. It was still young, but it was already growing. A few moments after it emerged, it scuttled off into the darkness of the castle. It would now grow, until it was a full adult.

Twilight Sparkle and her friends walk into a large room, and upon emtering, they see a large statue. It looks like a large sphere, with smaller spheres on spokes surrounding it.

"Girls, these must be the Elements. We need to hurry and get them off of there, before Nightmare comes. But be carefull."

Rainbow Dash and Fluttershy fly up and proceed to pull off all the stones, excluding the large one. They then set them in front of Twilight.

"What now? Anything we can help with?" Applejack asks.

"Well, the stories and legends say that the last element is brought put by a spark. So, maybe I can make one." Twilight answers.

She then strains, her horn starting to spark and flash with her magic. She surrounded the elements in her magic, and then tried to infuse them with the magic.

It didn't work. She panics, and tries again. And again. After the third try, she is worried.

"I don't know what's going on?! I can't seem to get them to spark." and they hear a laugh.

"Oh you foolish little ponies. You don't know anything about the Elements of Harmony. It was not supposed to be, and never has been, a physical spark. But the real spark, is for me to know, and for you to never find out." Says the mysterious entity that enters the room. The fog like being coalesces into the mare Nightmare Moon, and as she says the final sentence, she fires a beam of cold energy at the six girls in the room. They are blasted off their feet, flying into walls, columns, and other various debris. Nightmare Moon laughs at the pained mares in the room, and looks at them trying to stand.

She then looks down, to where she shot, and tries to find the elements. The elements she had made sure to miss, so as not to hurt them, were missing.

"What! What did you do to the Elements?! Where are they?!" Twilight and her friends struggle to their hooves. She looks to where the elements where, and sees them gone.

"What? I didn't do anything to them. They where right there?" she then looks around.

Unseen by all of those present, a creature has been skulking around the room. I was on the ceiling, watching the proceedings with it's senses, and echolocation. It hisses ever so slightly, and starts to make it's way down to the floor. it climbs down the walls, and reaches the ground. The holes in the ceiling provide light to the room, and the creature makes its presence known to the occupants of the room.

As all eyes turn to the unknown creature, it hisses, and stands up. AND UP. It stands, taller and taller. Eventually, it is done standing up.

The creature was about 7.51 Ft tall. Its exterior, was black, and looked like insect chitin. It had a tail, longer than it's body, and tipped with a dangerous looking spike, with small ridges leading from a foot before, up to the tip. It had long, well muscled arms, each one tipped with six fingers, two being opposable thumb like appendages on either side of the hands. Its head, was the most terrifying part of it.

It had no eyes. The top of its head, was smooth, and devoid of features. It snarled, and its lips pulled back, leaking saliva that dripped onto the floor. It opened its mouth, and hissed at Nightmare Moon, and showed it's second mouth in its jaws.

It started to advance on Nightmare Moon. The mistress of darkness, now terrified at the creature standing above her, slowly backed away. She charged up her magic, and blast the creature with a spell that would have frozen a manticore in seconds.

The creature didn't even flinch. It kept coming at her. She kept backing away, and finally, she hit a wall. She turned to it, and then back to the creature. She was now terrified, and kept firing off frost spell after frost spell, hoping one would stop the creature. The creature gets right up to the mare, and can smell the fear on her. Nightmare is crying, and shrinking back from the creature that has resisted her most powerful frost spells.

The creature gets down on the mares level, and opens his mouth, shooting its second mouth out to stop just at the mare. It stops just before her eye, and Nightmare Moon's eyes roll up into her head from the shock.

As the mare of the night faints, the creature jumps onto the wall. The remaining conscious ponies follow its movements, as it moves to a portion of the ceiling that has some holes that aren't all the way through. It then reaches into one of them, and grabs several objects out of it. It shows each one, and drops it.

Twilight's quick thinking, literally, saves the objects from falling upon the floor and breaking. As she levitates them before her, she sees they are the stones that have the elements. She looks back at the entity.

"It swiped them right out from under us." She says.

The creature then drops from the ceiling. It stands up to its full height. And then it hisses at the girls. The all skitter back in fright. It advances. Rainbow runs up to stand beside Twilight.

"Come on! I'm not afraid of you. We got your back Twilight. We can take this thing." Twilight smiles at her friends words, and then stops. At the smile on Twilights face, the creature also stops.

"Oh my Celestia. That's it! The spark isn't physical! I know what the spark is!" Twilight says.

The alien creature hisses. Fluttershy perks up from her hiding place behind Pinkie Pie.

"What did you say?" She asks, seemingly to no one. The alien hisses again.

"Twilight's right? She needs to use it against Nightmare Moon? What do you mean?" The creature let's out a shrieking hiss.

"Friendship is magic. The elements are of friendship. Magic is the final piece. Cleanse Nightmare Moon. Twilight, we need yo use the elements on Nightmare." Twilight had listened to the whole conversation, and with her theory confirmed, she nods.

Nightmare Moon was starting to come to her senses, and was getting up. Twilight and the girls stood in front of her defiantly.

"Nightmare Moon, I figured it out. Your right, it isn't a physical spark. It's the Spark of friendship. And when I heard my friends had my back, I realized, that I actually was happy. And I realize now that each of them embodies one of the Elements of Harmony. Girls, let's cleanse the Nightmare."

The stone orbs started to glow, and each orb started to hiver, each glowing a different color and spinning around a different mare. They spun faster, and began to glow brighter. As it got painful, they changed into different necklaces around five mares. Twilight was grinning, and then the giant orb on the pedestal glowed a lavender hue.

Out of the orb, a crown like object flew out. It flew over to Twilight, and landed on her head. Twilight was smiling.

"Nightmare Moon, Friendship is Magic." And a beam of magic came from the collective pieces of jewelry. It struck Nightmare Moon, and the entity inside her started to come out of the mare. The nightmare manifested itself as a black cloud, which was then disintegrated in the powerful attack.

What was left behind, was a small blue alicorn. She was taller than most ponies, but smaller than the current ruler. As she opened her eyes, she saw the creature that had scared the Nightmare. She whimpered, and shrank back.

But the creature turned, and ran away, disappearing into the shadows without a sound. The main six got up off the ground, having collapsed from exhaustion after firing the friendship canon.

"We did it. We beat Nightmare Moon." Twilight says. A motherly voice was heard then.

"Indead you did, my student. I am sorry, I didn't tell you my whole plan. But the whole thing hinged on you finding friends. All I could do, was point you in the right direction, and train you to defend yourself. Can you forgive me?" Celestia says. Twilight looks at her teacher.

"Yeah, I guess I can. But, you owe me for getting our asses kicked." She says. Celestia nods.

"That is understandable. Now, let's hope somepony else, can forgive me as well. Isn't that right, Luna?" The sun goddess says to the blue alicorn. Luna then hugs the white mare, and says.

"I am so sorry sister. I shouldn't have listened to it." Everybody present save the two hugging were surprised by this development. They took care of it differently. Twilight was thinking.

'Well, I guess it makes sense now why she didn't tell me everything. I probably would have ruined everything if I had known she was trying to save her sister. I can forgive her for this mess she caused me and my friends.' After she got done thinking that, Rarity spoke up.

"Wait, does anypony know where that creature went?" And everypony looked around. Celestia looked confused.

"What creature?" She asks. Luna speaks up.

"I saw it leave, just before Celestia arrived. It disappeared into the shadows. The creature was terrifying. It was so bad, the Nightmare shrunk away from it. And our strongest frost spell did nothing against it."

Celestia seemed disturbed by this. But she didn't say anything. Suddenly, she noticed one of the walls to the old throne room was broken. She gets up, and moves towards it. As she gets closer, she starts to feel a magical barrier, and as she continues on, it dissipates.

Where there was once thought to be a wall, was now a door, broken and blackened by an explosion. Out of it, came the smell of blood. And it was fresh.

"Twilight, you and the girls don't come any closer. Luna, come here." Luna comes over to her sister. They slowly make their way into the room.

Inside, they see a stallion, and blood. Scorch marks blankwt the walls, shrapnel of some crystal embedded in to multiple places.

The sisters enter the room. They walk over to the stallion. Upon getting closer, luna notices something, previously unseen in all the dark blood and shadows.

"Sister, look at his chest." Luna says, disgust showing on her face. "It seems to have been burst Out of. Also, look at his body. It isn't shaped like a ponies. Its more like those old tribes of ponies, the ones who were here before us."

Celestial nods.

"Yes, though those tribes consisted of both ponies and a hybrid, part pony, part Human, they said. They also are the ones who gave us this castle. Something seems off about all these coincidences." Luna nods as well.

Luna then see's something, in the pocket of the clothing the stallion wore. She pulls it out, and see's it is a piece of paper, folded up. Upon unfolding it, she finds a note, and reads aloud to her sister.

"Dear royal sisters,

You dont know of me, but I know of you. I have been awakened. And my children, will have hatched from the chest of this stallion. I am sorry for the loss of the life, but he gave it willingly, so my child may grow. I will not use any ponies, but other creatures, are fair game. If they are found, know that it is in protection of your kingdom, that they died. And if Fluttershy finds them, tell her they passed quickly, and painlessly. You will not meet me. Not yet. Yet my child, you might see, but do not seek, for ponies will be prey. I will leave you one thing, a name for my species.

We, are Xenomorphs."

As Luna finished reading, the two sisters heard a hissing sound coming from all around them. Looking around, they finally see. A single creature is in the room with them, up on the ceiling, above the body, near a hole in the wall leading outside.

In the light of the morning sun, the Xenomorph screeches at the two sisters, and then rushes out the hole, into the Everfree forest beyond.

Author's Note

This is a new story, one of two. This story won't follow full Aliens lore, so I'm sorry, but I will put some lore bits that I can find and will be important for the development of the aliens.

Also, I am not going to tell how she got displaced as a full chapter. She went to the convention, dressed as an Xenomorph queen, found a sculpture of a Xenomorph egg, bought it, and was sent three thousand years back.

The ponies at the time, long before the three tribes came and settles, found her, and she had them build her a place in the crystal caverns, connected to a trigger set in a castle that later became the castle of the two sisters.

She gave them some human DNA, and then had them figure out how to transform ponies into human-pony hybrids. After that, she was put into cryogenic sleep, the freezing being a slow time spell that was activated by the trigger in the castle.

The stone that was stepped on, had a slight deterrent spell, that steered any who might prematurely step on it from doing so. It wore off after 2999 years. And the descendents of the tribe who found the queen were tasked to forever keep one child who would be a hybrid.

All I am saying, is this was well planned. There is to be a small time skip, nothing great, but you might recognize it.

Have fun, and thanks for reading.
