Canterlot Castle, Equestria

You woke up startled. You just had a nightmare about the Flood landing here. If that happens, this planet will die in under a day. You got out of your bed and went looking for Luna. For it being in the middle of the night you had trouble finding her. You were about to give up, but then you saw a partially opened door. Strange, you never have notice that before. When you went inside, you were amazed. It was a workout gym, with equipment, boxing sandbags, and a training area. You walked in and saw Luna training on one of the sandbags. "Hey Luna," you said to her, which mad her jump.

"Oh, hi y/n, you scared the shit out of me," she said, being the first time you heard her curse.

"So, what is this place?" You asked her. "Is it your private gym?"

"Not really," Luna said. "But only me, Tia, Cadence and her husband know about this place, and now so do you." You remembered that Luna called Celestia by her nickname. Every sibling had a nickname for one another. You and your [brother/sister] where no different.

"So, do you mind if I use any of the equipment?" You asked.

"Go ahead," Luna said, focused on punching that sandbag to death. You walked over to the chin up bar and did 100 of those. Then you benched pressed 150 pounds. You can't do bench presses well, because you were more of an agile, fast kind of body type. Then You knocked three sandbags off their hinges, and you did this all in under thirty minutes. You decided to take a break, and saw that Luna was doing the same. You went over to go talk to her.

"Hey y/n, do you want to spar with me?" She asked as you walked over.

"Sure," you said. "Just prepared to get your ass kicked."

"I wouldn't be so confident if I were you," She said. "Princesses also have elite combat training."

"I'll still win," you said, as you picked up one of the training poles, and she did the same. When you both stepped on to the training area, you wasted no time getting down to business. She made the mistake of attempting to strike first, which you made her pay by rolling around her and hitting her in the back.

"Ow," she said. "Are you OK?" You asked her. "Yeah, if they weren't meant to hurt, the staffs would be softer." You two continued. She went on the offensive side, being smart and surgically hitting you in effective areas. But you blocked them all. Her attacks where getting predictable. You knew the easiest way to win a fight was to be unpredictable. You tried to hit her, just to see what she would do. Because of that, she ducked and tripped you, then popped up to lunge and attack again. But you started to swing the pole wildly to hit any on who came near you, which Luna made the mistake to do. She ended up hitting the ground. You walked over to help her up, but she pulled you to the ground, flipped over you and pinned you down.

"What where you saying about winning?" She asked, thinking she had you beat.

"Still saying it, I expected you to do that," You said knowing she was sitting on the training staff. You then use it to throw her up in the air. When she hit the floor, you walked over to her.

"Y-you win," she said. You helped her up.

"You did good," You said to her. "For living in a relatively peaceful planet, you blew my expectations for your combat abilities out of the water. But your attacks where way too predictable."

"Where did you learn how to do all that stuff?" She asked.

"The UNSC. They give really good CQC training to marines," you said.

"Can You teach me?" She said with cute puppy doll eyes.

"Only if your available every Tuesday and Thursday night," You replied. She looked so happy at your response, and it made you just as happy seeing it. After that, she asked you to leave she could change. You obviously did it, you didn't have that good of a relationship yet. You went back to your room to change as well. After you both Were done, you met up on a couch and started to snuggle.

"Hey y/n," She said.

"Yes babe," you said

"Do have any more episodes of that show thing on your chip. What is it called, Red vs Blue?" She continued.

"Of course," You said, pulling out the communication chip. "I have all 17 seasons of it." For the rest of the time you were up, you and Luna tried to watch as many episodes as possible. But eventually, you had to go back to sleep.

The Crystal Empire, Equestria

When the train pulled into the station, there were guards waiting to help carry your stuff. You waved the off because you where more than capable to carry your own shit around. You were kind of disappointed. Soldiers where meant for fighting, not hauling around luggage. That was meant for another person to be hired. When you and the sisters went to the castle you noticed something. All the people where shiny, like a crystal. You thought that was neat, and it is combat effective. If you reflect the sun and blind your opponents, you can take the upper hand. You had to focus. Celestia and Luna are tasking you with escorting them to the castle. At first the royal guards were hesitant, but then Celestia told them how she tried to jump scare you, but you didn't flinch because you noticed her five minutes ago. But the job made you a little paranoid. See with your job, you've seen the worst of the world and where tasked with killing it. It wouldn't be surprising if one person in this world wanted either Celestia or Luna dead. You had to protect them. When you got to the castle and went in, you let your guard down. The only way now for there to be a threat is if one of the guards tried to commit regicide. When you Entered the room, you saw Princess Cadence and her husband, Shining Armor, who was also Twilight's older brother. Because you did not know him, you offered to shake hands.

"Hi, I'm y/n," You said.

"Shining Armor. I heard you are a space soldier," he said.

"More or less. And I heard you where the captain of the royal guard. Seems like a high rank," You said.

"Yes, it is, how about you rank in the military you came from?" He asked. " I am ranked at a specOps sniper, not the best rank in the UNSC, but definitely not the worst, you said.

"Then what is the highest rank? He asked. You responded with "It depends what branch of the UNSC you are in, and if you went to college or not. The highest rank in the navy you can get is Fleet Admiral, but without college its petty officer. For the marines, the highest is General, or Sargent Major without college. But for me, because I'm a sniper, normal ranks do not apply to me ASIB4 is the highest rank I could have got."

Before Shining could ask another question, Cadence stopped him, and the Princesses got down to business. The discussed treaties, the state of other nations, doing a literal shit ton of red tape, the usual government stuff. When they were done, about two hours, two long hours, Luna decided to tell everyone that you were dating.

"Everyone, I have new to share. Me and y/n are dating." Luna blushed after saying this obviously embarrassed.

"Well, I wish you both the best of luck in your relationship and that it turns out for the better," Cadence said.

"Yes, same here," Celestia said. "But how long has this been going on for?" "Only a few days," Luna said.

"y/n and I wanted to keep the info private and only among friends because he didn't want to deal with the citizens giving him too much attention."

"Yeah," you said. "They will figure it out eventually, it doesn't take a genius. For about another hour, the you all talked about the general things in life, before you all had to go on the train and go home.
