A/N

Guest- Yeah, in this universe their Great War was like our World War, and that is actually what I am setting Niflheim to be. They are Remnant's Germany.

Guest II- I plan on giving Prompto, Gladiolus, and Ignis semblances that do somewhat go with what their "special" moves are in FFXV and thanks for the support! :D

Red- I know Noctis is older than Prompto, but I always saw Noctis as a younger brother of the group and it kinda worked for the pairings that I want to do, but yeah I have made some minor changes to somethings of the game just so that it would work with my fic.

Chapter V: Brothers

"I'm awake!" Prompto yelled as he felt someone shaking him to wake up.

Prompto had been studying in Beacon's library when he felt the comforting warmth of the library begin to embrace him and he soon found himself asleep on top of the book he had been studying. He looked up from the book he had been using as a pillow and saw lilac eyes looking back at him.

"Morning, sleepy head!" Yang said with her usual friendly voice.

"What time is it?" The still half asleep Prompto asked as he took out his scroll.

"Must've been hitting those books pretty hard, huh?" The blond brawler said sarcastically.

"Can't you tell?"

Yang takes a seat next to Prompto and gives him a questioning look.

"Uh… Is everything okay?" Prompto asked with a raised eyebrow.

"Y'know, for brothers, you and Noctis look nothing alike."

"Well, that's because I'm his adopted brother."

"Really? King Regis adopted you?"

"Yup!" Prompto said giving Yang a huge smile.

"What about your actual parents? What happened to them?"

The question caught Prompto off guard and the Prompto that Yang had come to know had disappeared. Prompto looked down at his feet and stood silent for a while. "They… They were killed by Grimm." Prompto replied still looking down at his feet.

"Oh." Was all Yang could muster up. "I-I'm sorry. It was a stupid question. I should've known something bad had happened. I'm sorry."

"It's fine, Yang. It happened a couple of years ago." Prompto said as he tried to fake a smile.

A silence then fell between the two blonds of their teams until Prompto spoke up.

"A few years ago my village outside of Insomnia was attacked… I was the only survivor." Prompto said with sadness present in his voice.

"Prompto, you don't have to tell me if you don't want to. I won't pry or anything."

"It's fine. I never really told anyone what happened that night. I just feel like I need to share."

"Okay…" Yang said as she looked at Prompto with worried eyes.

"You see… I… I wasn't born in Insomnia. I was born in Niflheim…" Prompto said as he looked up at Yang to see her expression. Yang looked at Prompto with a mix of surprise and shock, but said nothing indicating that she wanted him to continue.

"My parents were from Niflheim, but after the war, they despised the Imperials just as much as everyone else did. They started to protest Niflheim rule with others that wanted to get rid of the Emperor after his attempt at world domination. Soon after the protests started he Emperor Ledolas had begun executing protesters. My parents and other protesters escaped the kingdom and made our way to Insomnia, but were denied entry."

"That's horrible. Why did they deny you guys?"

"I don't really know, to be honest. I think it was because tensions were still really high between Insomnia and Niflheim and they were afraid that the grown ups would turn out to be spies. We decided to make a tiny village just outside of Insomnia. We hunted, and managed to keep ourselves protected from Grimm, until one night…"

6 Years ago, Outskirts of Insomnia

"Prompto, time for dinner!" A average height woman, with blond, long hair called from the dining room of a small brick cabin.

"Coming, mom!" Said an 11 year old Prompto as he ran down the stairs of the cabin house.

Prompto takes a seat at the table and waits for his parents to sit so they could eat.

"Smells delicious, darling." Says a tall, built, dirty blond haired man as he sits down at the table next to his son.

The family of three begin to eat their dinner when shortly after a scream of terror is heard from outside.

"Grimm! Grimm are attacking the defenses!"

The man gets up from his seat and grabs a revolver a holster that had been hanging from a hook by the entrance.

"You two go find a place to hide." Said the man to Prompto and his mother.

Prompto's mother picked him up from his seat at the table and the two head to the basement of the cabin as his father headed outside with his weapon.

Gunshots, fighting, and screams of death were all Prompto heard even with his mother's best attempts at covering his ears from the terrifying noises coming from outside. Soon everything had gone silent.

"Stay here, Prompto. And don't move until I come and get you." The blond haired woman said as she kissed the top of her son's head and made her way outside with a kitchen knife in hand.

Then more silence was all Prompto heard as he awaited his parent's return.

"Prompto! Run!" His mother screamed from outside the cabin.

Prompto got out of the basement and headed outside to follow where his mother's voice came from. That's when Prompto saw his mother and father on the ground, his father dead, and his mother gasping for air. Both with giant slashes on their backs and chest.

Prompto looked around him and saw nothing but the people he once called friends being mauled and dragged out of their houses by Ursas and Beowulves.

"Prompto…" His mother called out to him.

"Momma… Papa..." Prompto said as tears began to run down his face as he kneeled down by his dead father and dying mother.

"Prompto… You have to leave… Please…"

"I… I can't. I don't want to leave you and papa."

With what energy she could muster, Prompto's mother wiped the tears from his face and smiled at him.

"My beautiful boy… I… Lo-"

"Momma… Momma please don't go! Please!" The blond boy screamed as he shook his mother for her to wake up.

One of the Beowulves then took notice of the young Prompto and began to creep up on him. The beowulf then plunged at Prompto, but was stopped by a dagger.

Prompto then looked up and saw the Kingsglaive fighting the Grimm that had overrunned his village.

"Sir, we have a survivor here. What should we do with him?" Said one of the Kingsglaive.

"We'll take him to King Regis, looks like he was the only survivor."

Present day, Beacon

Yang couldn't help but give her blond friend a hug as he told her the story.

"I am so so sorry you had to go through that, Prompto." Yang said as tears began to fill her lilac eyes. "I can't imagine how horrible it was."

Prompto didn't reply, he sat there quietly, and shaking from reliving the events from that night.

"I… I'm okay, Yang." Prompto said trying to reassure Yang.

She let go of Prompto from the hug and wiped away the tears that had formed in her eyes.

"That night was the worst night of my life, but… It also opened me to friendships and bonds that could never be broken."

6 Years ago, Insomnia

"Your Highness, we have a survivor from the Grimm attack outside of the kingdom, a boy. Around the age of the Prince." A Kingsglaive said as he brought Prompto to the throne room in the palace of Insomnia.

The King sat on his throne as his Kingsglaive reported to him about the attack.

"How old are you?" The King asks Prompto as he makes his way down from the throne to Prompto.

"11." Said Prompto with his eyes to the ground.

The King gets on his knees and puts his hand on Prompto's shoulder "What's your name?"

"Prompto, your Highness." He replied with his eyes still to the ground.

"We will take him to the orphanage, my Lord." A member of kingsglaive said as he grabs Prompto by the shoulders.

"No, I will take him in."

"But, my Lord. He's from Niflheim."

"And it is because we denied the people who left niflheim entree that his parents were killed. I'll take in the boy and raise him as my own. End of discussion."

"Y-Yes, my Lord." the Kingsglaive said as he bowed and exited the throne room."

Present day

"King Regis could've just let his men send me to the orphanage, but he took me in and he did treat me like his own son. Even though Noctis didn't really treat me like a brother at first."

"Did he not like you?"

"I honestly didn't know. He always gave me the cold shoulder whenever me and him were in the same room, but he never really said anything to me."

"So… What happened? You two are like inseparable now."

"Well it was a couple of months after I had moved into the Palace and the King had business in Atlas so we tagged along."

6 Years ago, Atlas

"Alright, you two. This meeting shouldn't take long. Be good and I shall take you two out for some ice cream afterwards. Deal?" The King asked the two boys sitting in chairs outside of the meeting room at Atlas Academy.

"Deal!" Shouted Prompto in happiness with the thought of getting ice cream while his younger brother just sat in the chair in silence.

King Regis ruffles both of the boy's hair and heads inside of the meeting room.

"Hey, Noct! Wanna see these cool pictures I took on our way here?" The blond boy asked his black haired younger brother, but received no response.

Prompto sighed in sadness and looked down at his pictures.

"Y'know, Prince Noctis. You should learn to be nice to your new brother." Said one of the King's security guards as he saw the look of sadness on Prompto's face.

"He's not my brother." Noctis said with no emotion in his voice. "He's just some orphan my dad took in because he felt sorry for him."

Prompto looked at Noctis, saddened by what he had heard and started to tear up. He got out of his chair and ran out of the academy.

"That was uncalled for, Prince. He may be an orphan, but your father took him in because he witnessed horrors no boy his age should see." Said the guard before him ran off to look for Prompto. Leaving Noctis by himself.

Prompto ran through the streets of Atlas heading in random directions until he realized he had gotten lost.

"I miss you… Momma… Papa." Prompto said through his tears as he put his back on a building and slid to the floor and began to cry into his knees as he held them. It had been an hour since Prompto had ran off and the sun had began to set.

"Hey." A familiar voice called out to him.

He looked up from and saw Noctis holding two ice creams in his hand, one vanilla, and the other chocolate.

"I couldn't remember if you liked chocolate or vanilla, so I got you both." Noctis said as he handed both ice cream cones to Prompto and slid next to him.

"I-I'm sorry. I didn't mean to sound mean."

Prompto looked at Noctis and handed him the chocolate ice cream cone.

"Huh?" Noctis said, giving him a questioning look.

"Your favourite flavour is chocolate, right?"

Noctis then nodded and took the cone from Prompto's hand and they both sat there, eating their ice cream until the security guard drove up in an Insomnia vehicle.

"There you two are! The King was going to have my head if I didn't find you two!"

The two boys get in the car and begin to drive out of the kingdom.

"The meeting is running a little late and your father wants me to get you two back to Insomnia, before it gets any later."

Their vehicle meets up with a convoy of 4 cars that are to escort them back to Insomnia and they leave Atlas. A few hours of driving and the sun had set. Noctis and Prompto were both in the backseat fast asleep until the car then begins to swerve, waking the two boys right up.

Prompto looks out the window and sees the two cars ahead of theirs being attacked by a king Taijitu.

The 8 guards from the two cars get out of the vehicles with their guns drawn and begin firing at the giant two headed snake grimm. The two heads attack the guards and capture a guard in each of its mouths and toss the dead guard at the car where Noctis and Prompto are in, frightening the two boys.

The remaining 6 bodyguards circle around the snake and 3 are crushed by its tail, killing them instantly.

"You two stay in here" The guard instructs the boys as he grabs his sword and gun and heads out of the van to join the fray.

The 4 guards prove no match for the Grimm as they are eaten and tossed around by the giant snake.

The grimm then turns its attention towards the van where the two boys are hiding and slithers its way to them and knocks van to its side. Noctis and Prompto struggle to get out of the van, but they succeed. Noctis' right arm is damaged from the glass of the windows, and Prompto's leg had been cut up. The snake then picks up one of the guards and tosses it at Prompto, knocking him to the ground, helpless. The snake then begins to slither towards Prompto, but Noctis stands in front of Prompto, holding the guard's blade in his left hand and his right covered in his blood from the cuts of the glass shards.

"I won't let you hurt my brother!" Noctis yelled at the top of his lungs as he lifted the sword towards the fast approaching snake.

Prompto looked up at his younger brother with tears in his eyes.

The snake lunges at Noctis and Noctis prepares to attack, but the snake is then stopped by a sword decapitating one of its heads. The grimm shrieks in pain and its attention is turned towards the one that attacked him.

It turns towards the direction where the sword had come from and sees king Regis as a war axe, broadsword, war hammer, and double headed axe circle around him in crystallized versions and his security guards.

"Make sure my sons are okay, I'll handle this." He instructs his men as he gives the now one headed snake grimm death stares. The giant snake then lunges towards the King with its mouth wide opened, but is blocked by the broadsword, King Regis then pushes the Grimm back and launches his weapons at the snake and the snake falls to the ground, weakened by the attacks.

King Regis then walks up to the dying Grimm and summons his war axe.

"This is for hurting my boys." King Regis then swings down the axe with both hands, using all his strength and decapitates the head and the grimm starts to disintegrate.

King Regis then turns towards where his sons are being looked at, and they begin to run towards their father.

"Are you two alright?" He asked his boys as he took them in his arms.

"We're okay, just a scratch." Noctis said as he returned his father's embrace.

"Yeah, just a scratch." Prompto agreed.

"Come on, boys. Let's go get your scratches looked at." King Regis said as he picked Prompto up so he wouldn't walk on his bleeding leg.

Present day

"Ever since then, Me and Noct have always had each other's back." Prompto said with a small smile forming.

"Wow…" Was all Yang could say as she heard Noctis was willing to fight a King T aijitu to protect Prompto. "Remind me never to ask why some siblings don't look related." Yang joked as she tried to lighten the mood.

Prompto chuckled at the joke and looked at his scroll. "Looks like it's almost dinner time!" Prompto shouted in glee earning "shhhhs" from several students in the library.

"Sorry." Prompto said sheepishly while rubbing the back of his neck. Prompto then starts to head out of the library and turns to Yang "You coming?"

"I'll be right there."

Prompto heads out of the library and Yang gets up from her seat and notices a dropped photograph. She picks it up and looks at the picture.

King Regis, and Noctis sitting around Prompto with a cake in front of him that says "Happy 12th Birthday!"

She then turns the picture and notices words on the back

"First family picture"

Yang smiles and puts the picture in her pocket

"Yang, hurry up. I'm starving here!" Prompto said as he opened the door to the library.

"I'm coming, I'm coming."

Yang gets up from her seat and heads out the library
