==A Thousand Years Ago==
Humanity is finally gone. thought the now-Queen Celestia. Those monster have finally been saved. It was true(ish). There was not a single human left in the world, and Earth was no more, Equestria's Barrier had covered it days ago.But why do I feel so empty? She thought. Probably because of my sister and student. She decided. But I had no choice. She reasoned. The humans had corrupted them. I could not save them, they were already ponies. She thought desperately. Pure, perfect, lovable ponies. Yet they had been corrupted anyway. Just like so many others. Link Heartstrings, Terra Pie, Mara Lunamoon... the list when on for hours. They had been corrupted, and for that, they had died.
==Three Days Before==
Humans were everywhere. Men, woman. Children. And among them... ponies. Earth ponies, pegasi, and unicorns. Stallions, mares, foals. Laughing together, playing together, eating together. In perfect harmony. The human occupants of the bunker numbered almost ten-thousand. The ponies numbered almost seven-thousand. There were scientists and artist, cooks and beggars. Politicians and lawyers and doctors and teachers and priests. People and ponies from every race, religion, country, and career imaginable. All together, all at peace, all in harmony. For here, in their runic, lead, hidden bunker, they were safe. The lethal energies of Equestria could not tough them here. For the fist time in almost 8 years, humanity was safe. And that called for a celebration. There was singing and dancing and laughing and playing. Young boys fought with wooden swords side-by-side with young colts. Little girls played dolls with little fillies. Everyone was happy. However, that was about to change. Suddenly, a massive explosion was heard.
"What was that?!" yelled a man.
"Where did that come from?!" screamed a woman.
"Was it Celestia?!" panicked a mare.
"Have they found us?!" cried a stallion. Cries like these echoed throughout the compound.
"SILENCE!!" boomed the former princess, Luna. And like magic, everyone, pony or human, fell silent.
"Thank you, Princess Luna." said the President of the Bunker(they had spent some times setting up a democracy, equal rights for everyone, human or pony, even alicorns).
"It's just Luna now, Mr President." replied Luna.
"Of course." said the human. "Now," he continued. "We have not reason to believe that Celestia has entered the compound. Let us keep a level head in this." he reasoned. "Only organization can protect us. And organization drowns in panic." he said in a I-am-calm-so-you-should-be-too tone of voice that, surprisingly, made the crowd calmer. "I suspect that this is nothing more than a prank, by some no-good teenagers."
"Then allow me to correct that theory." said a male voice.
"Who goes there?!" demanded the president.
"Oh, just little ole me." replied the pony as he stepped out of the shadows.
"SHINING ARMOR!" screamed a woman. "HE'LL HAVE HIS ARMY WITH HIM!!" she panicked.
"RUN!!" shouted someone. And so they did. Parents garbed their children as they ran, but some did just the opposite. Unicorns charged their horns, human guards grasped their guns, and the sound of gunshot filled the compound. When it stopped, about 24 human and unicorns remained in the room, all others having fled.
"Is that all you've got?" asked Shining Armor.
"But-but how?" stammered a human.
"My special talent is defending of course." replied Shining Armor. "So it was quite trivial to construct what you humans call, what was it again? A wizard's wall." That made the humans turn pale. Yes, they had heard of a wizard's wall. It was part of a best-selling fantasy series from before the contact. It was the most perfect shield ever made, at least against non-magical opponents. It didn't expend energy beyond the initial set-up, it couldn't be broken, and it couldn't be bypassed. It stopped anything non-magical. Anything. You could explode a large sun on it and the people inside wouldn't even notice. The Equestrian Barrier was the same way. Fortunately, it did nothing for magic. Another shot rang out, and Shining Armor crumbled.
"How' d you do that?" asked a pony to his human comrade, who had just killed Shining Armor. The human smiled wolfishly.
"The wizard's wall stops anything purely physical, which means any technology. And he had a second shield to stop anything purely magical, like you're attacks. What he didn't count on was something in between."
"And what was in between?" asked the pony.
"A alicorn bullet, coated in copper, engraved with an ancient norse 'death' rune."
"ALICORN?! As in the sustenance unicorn horns are made from?!"
"Yes."
"AND WHERE DID YOU GET IT?!"
"I killed a newfoal."
"Oh. Okay then. Newfoals, not properly alive anyway."
"Exactly. Now lets get out of here."
"Agreed." said all the humans and human-allied ponies as the fled the room. Suddenly, a scream was heard.
"NEWFOALS!" screeched the voice.
"OH GOD, THEY'RE CHILDREN!!"
"Children?!" exclaimed the alicorn-bullet-user. He swore. "She must be sending our own converted young against us."
"Why?" asked a pony. "Celestia claims she's taking over Earth to 'save' humanity's children, yet she sends them here to die? Doesn't sound like a very good PR tactic to me."
"You got that right Twilight."
"Excuse me?" asked the pony. "What did you say?"
"Oh, please. You really thought no one would see through your veil? I mean, your face is almost identical, your mark is a checklist and a quill, you called yourself "Silverlay", AND you knew the "Princess of the Sun" personally before the fall. You didn't even have a good cover story."
"Huh." replied Twilight. "I admit I'm impressed, no human has ever seen through me veil before. May I ask your name?"
"Harry." replied the Human. "Harry Merlis."
"Interesting name for a human."
"Let's just say I'm... unique."
"Alright then." The battle raged for hours, the mindless army of Celestia versus the last of humanity. Humans fought back, forcing the ponies to fight for every inch of ground. For every inch they gained, the ponies lost a foot. Then she came. The Tyrant Sun: Queen Celestia Solaris of Equestria.
"CEASE THIS FOOLISH FIGHTING AND LAY DOWN YOUR WEAPONS!!" thundered the voice of the Tyrant. "WE HAVE COME TO BRING YOU SALVATION!!" But the humans didn't cease fighting, nor did they lay down their weapons. Instead, they rose them. To their own heads. They new the Queen couldn't be hurt without magic, and that was one thing they lacked, the remaining human-allied unicorns were nearly all dead. "NO!!" boomed the Queen's voice. "I WILL NOT ALLOW YOU TO KILL YOURSELVES!!' As she spoke she grasped the human's weapon with her magic and pulled them away. But the humans didn't give up. Since they could not fight, and they could not die, they ran. And oh, how they ran. All the way to the top of the bunker, all the way outside, exposing them to Equestria's lethal magic, killing them. Instead of becoming ponies, they had chosen to die. But this did not dampen Celestia's spirits. "MY LOYAL SUBJECTS!!" yelled Tyrant Sun. "TODAY WE HAVE SAVED HUMANITY FROM ITSELF!!" she shouted, and a cheer went up among her armies. Until suddenly-
"BURN IN HELL YOU MONSTER!!" Simultaneously, a titanic blast of black flames shot from underground, racing towards Celestia, who narrowly dodged it.
"Impossible!" She shouted, seeing who had shot it. "How are you not dead?!" For the assaulter was a human, and not just any human: Harry. With a left hand on fire. Black fire. He responded by hurling another blast of the prior mentioned fire at the alicorn. "How are you doing this?!"
"Celestia Solaris, Tyrant Sun Queen of Equestria. I lay my judgement upon you." The human said emotionlessly. "I sentence you to a fiery Hell." And so it began. When the alicorn tried to use her wings to gain an advantage, the human sprouted his own, demonic blood red wings of hatred. "Did you never think?!" He demanded as they fought. Did you never imagine, that maybe, just maybe, there could have been peace? Even once!?"
"It never would have lasted! Not so long as your kind were slaves to your barbaric nature!" This only served to enrage the human even more.
"OUR barbaric nature?! We're not the ones who wiped out billions of innocents just to stoke our egos! WE WEREN'T THE ONES WHO DESTROYED THE PEACE!! THAT BLOODS ALL ON YOU"
"I DIDN'T WIPE THEM OUT I CONVERTED THEM!!"
"YOU MURDERED THEM!!! EVEN NOW I CAN HEAR THEIR SOULS SCREAMING, TRAPPED IN A LIVING HELL, TRAPPED BY YOU!!!"
"WHAT'S THAT SUPPOSED TO MEAN?!"
"COME AND FIND OUT!!" Harry materialized a sword and charged Celestia. Celestia pulled out a bottle of potion in her magic and threw it. It hit Harry in the chest.
"No matter." Said Celestia. "You shall explain once you are a pony." A minute passed. Nothing happened. Another minute passed. Nothing happened. Harry stood up and brushed the break-away glass off himself.
"You honestly thought that would work?" Harry said as though sharing a joke.
"WHAT?!" howled Celestia. "HOW ARE YOU IMMUNE?!" She demanded. Harry chuckled.
"Your damned potion only works on pure breeds. I'm a mutt. Half man, half demon. They call me a cambion."
"If you possessed such power, why did you not use it before." Harry chuckled again before responding.
"For a cambion to wield their powers, they must first soar higher than ever before, then fall further than they have ever dreamed. I have never been higher than I was in that bunker, and never lower than after it's fall. I am the last of my kind You made me this way Celestia. Allow me to return the favor."
==Three Days Later==
The stone statue had once been the mighty cambion and the last human sat in the Newly Established Canterlot Gardens next to the statue that was once Discord. among so many others. Celestia starred at it, his last words ringing in her ears.
I will return.
