Hi! So this is my first Fanfic and I really hope you enjoy it and constructive criticism is accepted.

I don't own Percy Jackson. It all belongs to Rick Riordan

I warn you there may be violence in this story and it's an eventual Percico

Hierarchy Nonsense

Chapter 1

Nico looked out his cabins window which overlooked the Poseidon Cabin. He saw Percy coming out his cabin with the same goofy smile Nico had found himself becoming so attached to. Following Percy from his cabin was his new half brother Triton. He wasn't new like he'd just found out his heritage but he'd been living underwater with his father for years. He was basically an older Percy by appearance but Nico could sense something was off about the other boy.

It was almost breakfast so Nico showered and got dressed before making his way to the dining pavilion. As he walked in he got the usual quick glances as he made his way to his table. He wasn't hungry but he knew that if he didn't turn up the Percy would come bursting into his cabin to drag him down there. Most people would find this annoying or creepy but Nico liked how it showed someone still cared about him, even when no one else would.

Nico looked up to see Percy smiling at his from the Poseidon table and Nico felt a blush rise in his cheeks. His eyes looked over to Triton who was staring at Nico and Percy with a look of disgust. Nico didn't understand why Triton was so disgusted by the fact that he and Percy were friends but he did his best to ignore him. He suddenly noticed that Percy had stood up and was walking over to him.

"Hi Neeks" chirped Percy with his usual goofy smile.

"Hi Perce" said Nico "Shouldn't you be at your own table"

Nico looked over to the Poseidon table and he saw Triton was about to break his cutlery.

"Nahh, Breakfasts nearly over and Chiron won't mind" said Percy who was now sitting across from Nico. "So what are you doing after breakfast?"

Nico shrugged "I was just planning on going into the forest for a bit to get some peace"

Percy shook his head and laughed.

"Well I have sword practice after breakfast but after that do you mind if I join you" asked Percy.

Nico knew he could say no so he simply nodded his head.

"Ok then, I'll see you there Neeks" said Percy standing up.

Nico watched as Percy walked out of Pavilion and let out a sigh. He walked back to his cabin to grab his sword and a book he wanted to read that he borrowed from his father's library and walked out into the forest. He sat down against an old tree and read his book for at least an hour before he heard footsteps from behind his tree.

"Percy ... Is that you" asked Nico

He stood up and looked round the tree to find not Percy... but Triton.

"Nope, but close I guess" he said with a sneer.

Nico stepped slowly away from the older boy as he began to casually walk up to Nico. Nico looked to the ground where he saw his sword and his book. He hadn't grabbed the sword because he didn't think he'd be in any danger as he was still just in the border that protects camp but now a gut feeling was telling him that he should have.

He made a lunge for his sword but Triton was faster and grabbed him round the neck before slamming him into a tree.

"I need to speak with you demon spawn" spat Triton.

Nico tried struggling out of his grip but had no luck. "Talk about what?" He gasped.

Triton tightened his grip on Nico's throat before throwing him harshly to the ground. He threw him so hard that Nico bounced from the ground before landing painfully.

Nico could feel searing in his left wrist and let out a groan as he tried sitting up but triton placed his foot on Nico's chest.

"You're friendship with my little brother is unacceptable and wrong" said Triton adding pressure to Nico's rib cage.

"He's a son of Poseidon, one of the most powerful gods and you belong below the ground in a burning pit with your pitiful father" he sneered "You shouldn't be friends, you're not even worthy of kissing the dirt he walks on"

"The camp isn't run by any hierarchy nonsense" Nico gasped "So take you bad breath and people issues and get lost"

Nico knew that was a bad idea before he had even finished his sentence. Triton looked enraged.

"How dare filth like you speak to me like that" Triton spat. He raised his foot from Nico's chest and stomped it back down with so much force that Nico heard his ribs crack. Nico closed his eyes as they began to water and Triton delivered so swift kicks to Nico's sides.

Once Triton was finished kicking Nico he sat the boy up by his neck, invoking a hiss of pain from the younger boy.

"Your friendship will stop, one way or another, consider this a warning" said Triton. He tightened his grip "And if you tell Percy about this little encounter, you'll be staying with your father permanently.

Triton released his hold on Nico's throat leaving the boy coughing and wheezing and walked away towards camp. Nico sat there in silence for a few seconds taking in what had just happened when he heard some footsteps in the distance.

"NICO" called the voice that Nico found himself being addicted to. Then he realized that he couldn't let Percy see him like this.

"NICO, WHERE ARE YOU?"
