Percy Jackson was having a normal day.

Well before the dark mist came.

He was resting on the arpartments couch after a tiring day of training at camp. What camp?

Camp Half Blood. A training camp for demigods.

Percy woke to smoke. He panicked. With his water powers he flooded the house. But all he did was cause damage. He felt a cold shiver run down his spine and a really bad feeling overpowered his body. Percy quickly spun around. He took out Riptide and with a sharp zing, a three foot bronze sword popped out. Seeing nothing, Percy started to put Riptide away. As the sword transformed back into a pen, a dark puff floated into Percy. Literally. The dark puff looked like a black cloud with sparkles. It flew into Percy's back at disappeared. But it wasn't just given like that. Percy's eyes were no longer green. It was blue. Dark blue.

"Alright." Percy whispered sinisterly to himself. "Let's have some fun." He chuckled evilly. "And we'll start with this apartment."

Percy backed up and watched as his old apartment burn down. He smiled a cold smile. And left.

"Percy! What are you doing?" A voice yelled. Percy turned and sneered.

"Paul." He spat.

"This is your house too. Well, apartment. But same thing. Why are you burning it down?!"

"Mine? The only thing that's mine and will be mines is revenge. And sorry, 'dad' but you're in my way!"

"I'm in nobody's way! Just wait 'till Sally hears about this."

"Like Sally would care. She loves me more than anything."

Paul gaped at Percy. "Y-you're taking advantage of her. You never took advantage of her or anyone in this matter!"

"Well, things change, Paul. And I appreciate it if you could leave me alone."

"B-but," Paul grabbed Percy's shoulders before he could walk away. "This is her apartment too. Where would Sally live? Do you not care?!"

"Oh Paul," Percy said with sympathy. Fake sympathy. "Of course I don't care."

"W-what?!"

"Now leave me alone. I have thing to do. And I'll start by destroying you!" Perch rose. He held out his hands, palms up. Dark fire exploded on his palms and his eyes started glowing.

"Percy, please. Do you not care?" Paul pleaded. For a millisecond, Percy's eyes flickered from blue to green. But it was enough to take control again.

"Run! Paul run before I-aughhh!!" Percy felt the dark power returning his body. His voice sounded glitched and broken.

"Percy! I don't understand-!"

He didn't finish his sentence. Percy blasted Paul away before the dark magic took control of him completely again. The blast wouldn't kill him, but it wouldn't feel so good either.

Sorry it's short. I wanted to get a chapter out soon so you would at least know what's going on.

Thanks for reading.
