Metal Blade woke to the sounds of yelling. She groaned softly as she rolled over. She could feel the hard, cold floor beneath her. It reminded her of the time she had spent in the Southern... Oh, no! Metal Blade screamed in her head. Without wasting a second, she scrambled to her hooves, and looked around her, her eyes flitting left and right. She could feel her heart rate pounding in her chest. It was as she had feared. She was locked in a cell in the Southern Army's base. Locked in a dungeon within the Castle of Two Sisters. In the other cells, were residents of Ponyville. That explains why Ponyville attacked in in Sugarcube Corner. The real residents were here. Other groans from around her derailed her train of thought. She looked around, and, to her relief, she was not alone. Twilight, Luna, Cadence, Shining Armour, Applejack, Pinkie Pie, Fluttershy, Rarity, and Rainbow Dash were all with her. Wait a minute... Metal Blade began to feel her heart pound even faster. Where's Ruby?! Without sparing any time, she turned her concentration towards the cell door, focusing her magic into her horn with the sole intent of blasting the wall in, but no magic came to her. She quickly felt her horn, and to her horror, she felt a small, metal object wrapped around it. A magic nullifier! She realized. Without thinking, she charged at the cell door, slamming against it with all the force she could muster.

"Ruby!" She screamed at the top of her lungs.

She could hear groans from the others, but she did not care. Ruby was with Argon, and she needed to save her. How? She didn't know, however, all of her noise she had made had successfully woken up her friends.

"Somepony..." Twilight mumbled into the floor. "Stop that noise."

"Twilight!" Metal Blade yelled as loud as she could. "Argon has Ruby!"

It was as if lightning had struck the room. Everypony was suddenly up on their hooves, all trying their hardest to take the doors down. Some however, trying to take off their magic nullifier rings.

"Hey!" A gruff voice sounded from atop a flight of stairs. "Keep it quiet down there!"

Just then, a softer, and kinder voice spoke up.

"Don't you remember, Blaze? We were supposed to take them to Argon once they regained consciousness."

"Ah... Right you are, Frost." Blaze replied in a softer voice. Then, in his loud voice, as if her were commanding an army, he spoke again. "All right! Fetch me the prisoners, so we can take them to Lord Argon!"

All at once, a squad of ten ponies came down the flight of stairs, each on wearing the signature red and black armour that represented their status as guards in the Southern Army. One calmly unlocked the doors, then stepped aside to allow Metal Blade and the rest out of the cell. On her way out, Metal Blade examined the armor the guards had. She could tell they were enchanted, so physical harm was out of the question. She realized that her only option was to go quietly to meet Argon. Celestia. She reminded herself. It's Celestia, not Argon. It's obvious. Why else would all of Ponyville attack just because she nodded her head? But was that even Ponyville? They arrived in front of two large oak doors.

"In." One of the guards said, and shoved Metal Blade into the room beyond.

After she regained her balance, and her friends had entered the room alongside her, she looked around the room. It was a sept. An underground sept, with many different halls that she knew leaded to different places that she knew was below the Castle, each hall had two guards. Each one sporting the black and red at armour. Yet the place looked like it was decorated for a ritual. There were red and black banners, with gold lining just about everywhere she looked, and in the center of the room, were ten candles, all laid out in the pattern of a circle, and there, in the middle of that circle, was Ruby, looking scared out of her mind.

"Ruby!" Twilight and Metal Blade shouted in unison, whilst the others simply stared at the scene in horror.

Twilight and Metal Blade began to run towards Ruby, but a cloaked, hooded figure stepped out of one of the halls, and silently cast a teleport spell. Suddenly, Twilight and Metal Blade found themselves back where they were before.

"Stay." The pony said in a gruff voice, before calmly waking over to Ruby.

"Argon, I take it?" Twilight spat.

Argon nodded, and lifted his hood. He was a dark red unicorn stallion, with dark grey striped running down his back, and a jet black mane, that looked alarmingly like Ditzy's. He was taller than the average unicorn, but the feature that stood out the most were his eyes. They were a deep Crimson colour, that brought out the blood lust in his eyes. It was almost hypnotic, if you were to stare for too long. Twilight opened her mouth to speak, but was cut off by Metal Blade.

"That's not Argon, Twilight. Argon never existed. That's the princess."

She hadn't meant for it to sound so blunt, but the reactions she got were jarring.

"DO YOU REFER TO MY SISTER?!" Luna roared at Metal Blade, the hostility in her voice apparent. "PRAY YOU DO NOT, OR I WILL HAVE YOU HUNG FOR THIS OUTRAGEOUS ACCUSATION!!!"

Suddenly, Metal Blade felt somepony give a sharp blow to her stomach. She fell to the ground, wheezing slightly as Twilight drew her forehoof back.

"Don't. Ever. Say. That. Again." She growled to Metal Blade, while her friends made similar noises of shock and outrage.

"Girls." Metal Blade weakly protested as she picked herself up. "Please listen to me. I know this, because-."

"Because what?!" Twilight screamed at Metal Blade. "You had better have a good enough reason for this outrageous claim! For if you don't I will send you to the darkest dungeon in Equestria!"

"Listen to me!" Metal Blade yelled back. "I know, because when we were all at Sugarcube Corner yesterday I saw Celestia give a nod to a pony next to her! That was when I warned you, but I was too late!"

Twilight stamped her left forehoof on the ground in anger, her expression livid. "THAT DOESN'T MAKE ANY SENSE!!!"

"Oh? Then where is she?" Metal Blade replied.

"Simple!" Twilight responded. "She's right... over..." Twilight looked around, searching for her mentor.

Luna looked for her sister as well, her shock and anger replaced now by genuine horror. Due to the fact that Celestia was nowhere in sight, Metal Blade now had some claim to her statement. Suddenly, Argon began to chuckle, earning him the attention of everypony in the room.

"What's so funny? Where have you taken my sister?!" Luna asked, her voice rising rapidly.

"Dismissed." Argon said, waving a hoof as he did so.

At once, the guards exited the room. Leaving only Argon, Ruby, and the others alone in the room.

"Where is my sister?!" Luna roared at Argon once again.

"Oh, LuLu." Argon spoke, his voice now sounding alarmingly like Celestia's. "You're so easy to fool."

"WHAT?!! Luna bellowed at Argon. "DO NOT JEST WITH ME, YOU SCOUNDREL!!!

Argon said nothing. Instead, he calmly charged his horn up, and let loose a wave of golden light, and as it washed over him, he began to change shape. His already tall form became taller, his coat turned a pearl white, on his flank, the cutiemark of the sun was born. His jet black mane became one of a rainbow of sorts. His eyes reverted back to their original violet appearance, and from his back, a pair of wings sprouted. After some other changes were made, Argon was gone, and there before the horrified group, stood Princess Celestia.

Twilight felt her heart grow cold with fear as she witnessed the unmasking of Argon. She now knew that Argon was indeed Celestia, for she knew a magic terminator spell when she saw one. She now knew who her mentor was... and it hurt. It hurt to see the pony she had viewed as a second mother betray her. It hurt to find out that her closest friend was her worst enemy. It hurt to see her idol turn out to be exactly what she despised. All her life, she had viewed Celestia's greatness as her goal, and she had tried to match it, but now? Now she saw Celestia for who she really was. A cold hearted, power hungry pony. She might have been able to feel rage, but her sorrow, and hurt overpowered any other emotions she might have felt at that moment.

"Twilight." She heard Celestia's voice, and looked up hopefully, hoping this all was some sort of prank. Instead, all she saw was Celestia with a small frown on her face. "I want you to join me, Twilight." Celestia began. "I can offer you so much in this. I want to build a new world for us, where we can rule as deities, but I don't want to do this alone, so please. Join me."

Twilight felt all of her sorrow turn turn to anger. Her mentor, Princess Celestia, wanted het to rule by her side? After she had lied, and betrayed Twilight? After she had foal napped her daughter? After she had pretended to care for Ruby's safety?! Twilight took a few deep breaths, prepared to give her mentor her answer.

"No." She said

"What's that?" Celestia inquired, stunned by her student's response. "You said no?"

"Yes, Primcess. I said no." Twilight clarified. "You betrayed me, when you were like a second mother to me. You worked against me, when you pretended to be on our side. You PLOTTED TO FOAL NAP RUBY, WHEN YOU PRETENDED TO CARE FOR HER SAFETY!!!"

Celestia turned her head away from Twilight's harsh glare. "I see." She finally muttered. "I had hoped your answer would be different." She then turned her head back to Twilight, but her eyes were fixed in a point beyond. "Kill her now, Starswirl."

Suddenly, Twilight felt a sharp pain in her heart. She looked down, to find a long metal spear sticking out of her chest. She couldn't hear much anymore, but one so ment stuck out amongst at the cries and screams she could only dimly hear.

"Good bye, my... Faithful student."

Rainbow saw her friend, her closest friend, get pierced by a spear, just like everypony else. She was unable to stop it,crust like everypony else. However, she was the first one to reach her friend when the last of her life left her body. She couldn't stop the tears in her eyes from flowing, nor did she want to. Then she heard a voice. One that silenced the others. One that should have died a long time ago.

"So she was your prized pupil?" A snide voice called out. Silencing her friends. "What a pity."

Rainbow looked towards Celestia, just in time to see a silver flash of light, and from it came a silver unicorn, with the longest beard she had ever seen. That was when she felt a surge of uncontrollable rage.

"You... BASTARDS!!!" She roared at the top of her lungs. "I'M GOING TO BUCKING MURDER YOU ALL!!!"

"I'd like to see you try!" Came a voice that was all to familiar to Rainbow.

"Th... Thunderlane?" She squeaked, her voice no louder than Fluttershy's.

"Yes." The stallion said, stepping out from a side hall, advancing on Rainbow Dash. "It's me." He jeered, taking out a knife from his belt.

All of the fight in Rainbow left her body. She couldn't do anything. Her hung legs buckled, causing her to fall down into a sit position, Thunderlane advancing in her all the while.

"But... You... Thunderlane... Why?" She squeaked.

"You want the truth, Dash?" Thunderlane spat. The spite in his voice unbelievable. "I've always hated you. I may never have shown it, but I always have. You always rubbing your achievements in everypony' face like your the boss. I remember when Cloudsdale charged us with supplying the water. You took charge and tried to use if for personal gain. Always bossing us around like its no big deal." He was standing over Rainbow now, relishing in the fact that her friends were too shocked to even stop him. He placed his left forehoof on Rainbow's shoulder. She made no effort to stop him. "We have only one price in the Southern Army for that." Thunderlane readied his dagger, and shoved it twice into Rainbow's stomach, then for good measure, slit her throat. "The price is death." He said as she slumped to the floor.

He never gave her time to scream.
