Part 2: Chapter 8:
Luna shielded her eyes with her right wing as Nova teleported both Alpha and Charlie away, back into the mountain, to their separate rooms.
"So, you decided to side with them?" Said a voice behind her. She knew exactly who it was; no pony else talks with such pride and royalty. "Father would be disgusted by your choice." Celestia said with disgust as she limped toward her ex-sister.
Luna turned her head around and sneered at Celestia, noticing her limp and scarred flank. "Looks like he taught you a lesson."
"What?" Celestia said as she looked at herself. "Oh, yes. Well, I wasn't ready. He caught me off guard."
"Right…" Luna said slowly as she turned to face the middle of the room. "And that open scar on your flank was always there." She said as she chuckled. "You are aware that you are the WORST at lying, you know that right? You couldn't even hide your obsession with cake from the public!"
"That's not true. You and I both know that was a rumor." Celestia said as she stood next to her.
Luna's jaw dropped in disbelief. "Are you serious? There's a fucking picture of you eating cake in the Museum of History!"
"No there isn't." Celestia replied, ignorantly. "You always were the loud one."
"You are worse than your cousin Blueblood."
"Hey, he's our cousin."
"Not mine anymore. I am not your sister now. No longer considered royalty. I do not use my crown, nor do the others call me 'Princess Luna'." She watched as her sister's leg began to heal inside the beam. She snorted loudly as she saw how slow it healed.
"What's so funny?" Celestia said, watching her leg heal.
"I know an eight year old colt who can heal bones faster than you in that beam."
"Yeah, I killed him a long time ago. Wait." She suddenly looked at Luna. "We are talking about Epsilon, right?"
"Who?" Luna asked, confused.
"Epsilon."
"Who's Epsilon?"
"Epsilon, as in Beta's friend."
Luna stared at Celestia, her eyes open wide before teleporting away. Before she did however, she shot a bolt of magic at Celestia, pushing her away from the beam.
Celestia screamed in agony before regaining self-control and lowered the scream into a growl.
The following day, Alpha was working in the metal-work room, wearing a face mask while modifying his welding torch to be able to use it at a higher temperature than it could be used so he could repair his wing on the go, not to mention using it as an improvised weapon. Luna entered the room and watched Alpha as he and Beta slowly increased the amount of fire through the nozzle. She looked around and noticed Charlie on the right side of the room, sleeping in the corner, his right eye open and green as Delta kept a cautious watch.
The glowing eye looked around the room before noticing and focusing on Luna before blinking twice then closed as Delta finished his watch. Luna walked over to Alpha, nudging him with her wing. Alpha stopped what he was doing and looked up, flipping up the face mask with his free hoof and smiled as he recognized Luna.
"Hey. What's up?" He said with a friendly smile.
"Nothing really." Luna easily lied. "Is Beta awake?"
"I am. Why?"
"After Nova teleported you two," She nodded at Charlie. "back to the mountain, Celestia appeared behind me."
Alpha's eyes widened.
"After a brief talk she mentioned the name 'Epsilon'. Does that ring a bell?"
"Yeah. Epsilon was one of the bullies I spared during my Rampage."
"Why did you spare him?"
"I pretty much mind-raped him, but doing so I learned out that he was a mutant in hiding. I spared him after I learnt that although he bullied me, he was forced to do it out of peer-pressure and the fear of being found out. Why?"
"You spared him, as in he survived, right?"
"I think so, yeah. Why?"
"Epsilon…Epsilon…" Delta muttered as he slowly stood up and walked over to Alpha. "Sorry about interrupting but I heard you speak about Epsilon."
"What do you know about him?" Luna asked.
"He…was my…third in command? Sombra was my Second in command. Why?"
"Delta… I have no idea how to ask this nicely but did Celestia kill you?"
Delta nodded. "I don't really like thinking about it. It wasn't very fun dying. Painfully."
"Did Epsilon take over after you died?"
"He was dead long before I died."
"How?"
"Why are you so interested in this?" Beta asked.
"It's fine Beta. During the second month of the Battle, Celestia sent out her personal death squads, nicknamed 'Death's Children', these squads were pretty much the representation of Beta's bullies; mean, strong, and hard to kill."
"I know. The platoon of the 117th."
"Right, well we mutants were able to overpower most of them easily, but during the third month, Celestia herself began to kill. Easily overpowering mutants like a sledgehammer against an orange. Epsilon, my third in command, stayed behind, against orders to retreat in hopes of buying his friends time to escape. He had a wicked ability to heal not just his own but other ponies bones. Celestia found him and well, they dueled." Delta sighed sadly. "You can figure out the rest."
Luna realized her mistake and quickly apologized. "I'm sorry; Celestia mentioned his name and said that he was a friend of Beta's. Just wanted to make sure."
Delta shook his head and smiled. "It's fine. It's in the past and we can't do anything to change it but hope we don't repeat our mistakes in the future."
