What secrets does Vault-Tech hide under those lies of safety?

PoV: Steel Breaker
Location: Ponyville, Equestria (Formally known as The Capital Wasteland)
Time: 1:00 P.M

Tia, Dogmeat and I have been walking through ponyville to meet with Luna, while the residents seem afraid of Dogmeat he doesn’t pay them any mind. We soon heard the sounds of flapping wings, looking up I saw it was Luna and her guards. She landed gracefully as the crowd of ponies were bowing at her and Celestia.

Luna walked timidly towards me, trying to avoid eye-contact. She got closer to me, earning her a threatening growl from Dogmeat, resulting me and Dogmeat being surrounded by spear points.

"Spears, really?" I asked as I turned to Celestia and gaining a shrug from her.

"Do you even know who you're talking to!? She's the princess, show some respect you filthy dirt pony!" A unicorn guard said as he jammed me with his spear. I focused on all the guards, my eyes turning green as I activated V.A.T.S. and targeted all of them for a sweep kick. I quickly got on the floor and sweep kicked all of the guards, making them fall on the ground. I got up and dusted my hands as I walked towards the unicorn guard with a straight face.

"Pathetic." I growled as I turned to Luna.

"And you have some explaining to do!" I shouted at her, earning a calming nuzzle from Dogmeat, calming me down.

"Start with why you locked me up." I sneered as I sat on the floor, petting dogmeat as he laid on top of my lap.

"While I was Nightmare moon and before going to fight my sister, I had remembered that you could easily have fought me and won without even trying, so I had only one option, smash the vault control panel inside and close the door, leaving you trapped inside." She said, looking down in shame.

Dogmeat let out a small whimper as he looked at Luna. I remembered that he and Luna were the best of friends and the night when she locked us up broke his heart. Luna started to tear up and got on her knees.

"I'm sorry Doggy, I'm s-so s-sorry." She sobbed, a few tears making their way down her face. Dogmeat got up, walked towards her and began to nuzzle her. She quickly embraced Dogmeat as she started to cry.

"You could've talked it out or create some festivals celebrating the night for the nights but you chose to forcefully take the throne and almost destroy the world." I said, still angry at her but sighed as I looked at her.

"I may not be the best influence on you two but I know I had taught the both of you how to talk your way out of a fight." I said to her.

"And finally, What would your father think if he was here?" I said.

"He would be disappointed in me." Luna whimpered, still hugging Dogmeat.

"No, he wouldn't be disappointed, just heartbroken." I spoke softly as I offered my hand to her. She grabbed it as she used to pick herself up.

"How's your arm doing?" Celestia asked as she healed her guards. I looked at my right arm and flexed it a bit, resulting in to move awkwardly as it emitted a mechanical grinding to emit from it. I sighed as I realized I need to get it repaired.

"I need to get Andy." I said as I began to walk but stopped as the Pip-boy showed an incoming projectile. I leaned back easily as a spear flew by and planted itself in a wall. I stood back up and saw that it was the racist unicorn that threw the spear.

"Stand down, Lieutenant!" Celestia shouted as she grabbed him with her magic. I flipped him off as I began walking back to the Vault to get my arm fixed. I stopped and looked at Dogmeat.
"If you need me boy, I'll be back at the Vault for a bit, but I'll be back." I said, gaining a nod from him.

PoV: Twilight
Location: Castle Friendship, Throne room
Time: 2:30 P.M

I was visited by my old mentor and her sister an hour ago to discuss Steels living arrangements, while in the middle of conversing, I've noticed that Luna seems strongly attached to Dogmeat. I asked where Steel went and they informed me he went back to the Vault to get something done. That was an hour ago and he still isn't back. I needed to find him, as the Everfree is a dangerous place no matter who you are.

"Twilight, where are you going?" asked Spike interrupting my teleport.

"I need to find the stallion we found today. He's been out in the forest for about an hour and a half." I said to him.

"So? He could take care of himself, right?" Spike said.

That made me remember earlier today, when he took down the pack of timberwolves without even breaking a sweat.

"Maybe, but it wouldn't hurt to make sure he's alright." I said, earning a sigh.

"Fine but I'm coming too." He said as he stood next to me. I cast the spell and appeared in front of the Vault door in a flash of lavender light.

"What is this place?" Spike said as he walked through the door.

"From what Steel said, this is a Vault, a place where it was safe but he didnt tell me from what." I said leading Spike to the R & D section of the Vault. I heard screaming coming from inside the room.

"Only a little bit longer, Sir and it'll be good as new." I could hear Andy's voice over the screams of agony. I opened the door and went inside. What I saw shocked me, Steel was laying down on an operating table while shirtless and his right arm was gone, blood could be seen dripping out.

Andy then turned around holding Steels arm, though it wasn't a regular arm and started reattaching it.

The sound of flesh being pierced could be heard as it slowly reattached to his body. Looking next to me and Spike staring horrified at the gory mess.

"There we go, see if it’s good now." Andy told Steel as his arm started to move sitting up and moving his arm, he started flexing his fingers and wrist, then proceeded to move his hand.

"How long have you two been standing there?" He asked out loud, not even looking at us as he started to use what looked like magic on his arm, making it look inconspicuous.

"We got here when Andy started putting your arm back, speaking of which, what happened to it?" I asked him levitating a bucket over to Spike, just in case.

"Long story but It has Celestia and Luna's father making the arm." He said as he put on his shirt and Jacket.

"So, you want me to keep this a secret?" I asked him.

"Nah, let them judge all they want, I dont give a flying fuck about discrimination." He said as he began walking out.

PoV: Steel Breaker (The Lone Wanderer)

"How can you use magic if you're an Earth-pony?" Twilight asked me.

"I ain't a normal Earth-pony, that's for sure." I said as she prepared to teleport back to her castle. I was blinded by the flash created by the spell and regaining my sight in Twilight’s castle. I looked at my Synthetic arm sighing as I recalled the events leading to it.

"Come with me Steel, I want to study the thing on your wrist." Twilight said grabbing me with her magic and dragging me off to Gods know where.
