You will have to listen to What I've Done by Linkin Park. I'm picking on Nico again. I'm always picking on Nico. I'm bullying a fictional character.

Nico's POV

The sun glared at the dying ground of sand. Nico slowly took in his surroundings, heart seizing up. Small droplets painted the ground, droplets that turned to form larger puddles of scarlet.

It was a picture of dead bodies, both monsters and demigods. They were carrying slash marks, some with the light scratches of blades, others with the giant gouges of talons and claws. The heat of the sun only enhanced their motionlessness, the way the soul seemed to be empty. Nico's sword slipped from his wet, stained fingers as he trembled.

Among those bodies lay familiar faces: Annabeth, Percy, Hazel, Frank, Leo, Jason, Piper... His heart sank. The unstoppable demigods, the seven of the prophecy, lay like limp ragged dolls on the rough sand, sleeping on a bed of their own blood. Still trembling, he leaned closer, and with a dull horror, he realised that some marks were caused by demigod weapons. By swords.

His sword.

No. His couldn't be right. He didn't do this. He didn't kill them.
But you killed Octavian. Or have you forgotten about that?
But that was necessary. That was different.
Was it? Or are you saying that to justify yourself?

Nico stepped back and tumbled, falling to the ground with a thump. A voice groaned. Reyna lay behind him. The wound on her chest was seeping red tears as she coughed. "Nico..." (A/N: is this a repeat? Unintentional.)

Nico scrambled closer and put her head in his lap. "Reyna, oh my gods Reyna, it's going to be okay, you'll be fi-"
"No I'm not," she spoke hoarsely, "you made sure of that when you stabbed me."

Nico inhaled. "I did what?" He whispered.

"You stabbed me Nico. You killed all of us."

No. No, this couldn't be true, Reyna was lying, blood loss was making her delusio-

"I know what you're thinking." Reyna gave him a tired bloodied smile. "It wasn't you. You would never hurt us. Well you did."

No no no.

"We begged you. We needed out. We've done so many horrible things in life and we just couldn't live with the guilt anymore. We showed you how much we hurt. In the end you agreed, you would make it quick. You bought us here, to the middle of nowhere."

Nico would've never agreed to such things, he-

"We were confused at first. But then you unleashed the monsters and you let them attack us. You lied, you promised to make it quick. But you watched them attack us and you laughed. The true nature of Hades revealed itself, the dark, cruel, malevolent side."

Tears formed in his eyes. Was this really him?

"And we're so proud of you Nico."

What?

"You've always been so drawn away from us, so out of place that it seemed you would never grow into yourself. But when that side of you emerged, we saw that you were growing up into that strong, beautiful demigod we always knew was there. We were scared at first, but then we were proud, proud of our little Nico as he tore our skin and shed our blood."

Tears slipped down Nico's face.

Reyna's brown eyes were starting to dim. "Percy and the others always saw how miserable you looked. It always increased slightly when you looked at us. Then it hit us that we tied strings to your past and misery. It only added to the pain we already felt. So we came up with an idea. Our lives were full of pain and aching and you were reminded of sorrow when you saw us. We didn't want to live anymore.

Those last moments, we realised how hard it has been for you. You were a true Ghost King and we loved you. We have always loved you, the way you are. And we are hlad to have died by your hand."

Reyna slowly closed her eyes. "Never forget that Nico."

A sob escaped Nico's lips. Tears poured down his face as held Reyna's dead body in his lap.

He cried for his friends. And he cried for his new freedom.

For some reason, 4th of July by Fall Out Boy played in my head when I wrote the last few bits. How was America's fourth of July?
Technically, it ended 17 minutes ago.
