Artemis's POV

When I flashed in, I could see the gods had their weapons aimed at the assassin and commander. I was about to warn them, when the assassin waved his hand, and their weapons shrunk. Dad's bolt became the size of a toothpick, Poseidon's trident became the size of a keychain. The same happened with the weapons of the others. The assassin made some chairs appear out of nowhere and he and the girl sat down. His cloak changed shape and became a suit. The same happened with the girl. The man and said,'Now we can talk like normal people'. My father immediately shouted,'WHO THE HELL ARE YOU?'. I almost laughed, but the assassin replied,'I am rhought that Chaos would have told you when we were coming, but sure, I am the Assassin of Chaos, Nebula Havoc'.

The girl said,'I am the Commander of Chaos, also known as Diamond Grace'. Immediately, my father calmed down. I felt the tension in the air calm down a bit as they said this. Poseidon then said,'We are grateful for your help'. Everyone on the council nodded at his words. Then, Athena asked the assassin,'We do not know the power you hold, could you be willing to give us a demonstration?'. The assassin thought for a minute before nodding. I thought he was about to summon his sword, but what he actually did was ask,'I need around 3000 square miles, to show around 0.001% of my power'. My eyes widened. That was a lot of space, he would only use 0.001% of his power. My father nodded and they both disappeared. A screen appeared in the center of the throne room and you could see both of the figures. They were in an arena which was around 3000 square miles. The assassin got his 2 katanas out. He then slashed at the air so fast, I couldn't see his hands. Then, a small white light ball began to form. It began to grow as he somehow went faster. When the ball was the size of a car, he punched it with his hand. As it flew upwards, he flew and slashed it with his right sword. Suddenly, the color of the ball changed and slowly so did the shape. It took the form of some hole, but the problem was it was sucking in air. It was so powerful, the ground began to split. Then, the ground began to shake and began to rise. Boulders formed and the were sucked in by the hole. In 1 minute, there was a massive crater on the ground. The assassin flew upwards, and slashed the hole with his right sword. Immediately, the power of the black hole decreased, until it was gone. Then slowly, the black hole disappeared.

I was shocked, but when I looked around the throne room, so was everyone else. My father was speechless, mainly because he had never seen anyone do this before. The assassin landed on the ground, and he performed the same process he had before, but instead of slashing at the ball with his right, he slashed with his left. The ball glowed and turned purple. The assassin flew out of the arena. As he sheathed the katanas, there was a massive explosion and a bright light shone which was so powerful, that it made me close my eyes. It was so powerful, it blew me back and the others on to our seats. When the light cleared, the crater had become even more bigger, but what surprised me was that the assassin wasn't even out of breath. Then, the assassin and the commander reappeared in the throne room. We all stared at them. They were really powerful. I thought that my father was going to kill them as they were a threat to him, but instead he said,'Thank you for that demonstration, now, could you be willing to teach some of the campers'. The assassin thought for a minute before looking at the commander. She nodded and the assassin said,'We will train them, but we will teach them the basics of what we were taught'. Father was about to complain, but Athena said,'Very well, you can teach them the basics only'. They both nodded and disappeared.

Percy's POV

We arrived at the bottom of Half Blood Hill. I sighed, this was going to a long day. Me and Piper began to walk forward, but suddenly, a few campers came out of nowhere. They had either their swords, bows, daggers or spears pointed at us. I was about to rush forward and cut all of their weapons, but Chiron came and asked,'Are you 2 the soldiers that Chaos mentioned were coming'. Me and Piper nodded and the campers became shocked when they found out we worked for Chaos. Unfortunately for them, an idiot didn't believe it. The voice shouted,'Yeah right, there is no way that it possible'. I looked at where the voice came from, and I realised it was Matt. I sighed. He really was an idiot. He said,'I bet you are actually weak and I could beat you without trying'. Chiron said to him,'Matt, don't try to mess this up for us'. Matt didn't listen and said to me,'I could easily beat you'.

I smiled and said,'Sure, I we can have a fight, but to make things a bit more even, I won't even use 0.0001% of my power'. Matt was obviously angry at being ridiculed and said,'Sure'. He led me and Piper to the arena. When we got there, he summoned a sword to his hand. I just made Nightblood appear in my hand. The sword was looking more deadly than usual, that it mainly because the angrier I get, the deadlier it becomes and even a little cut, can hurt a thousand times more. I just held my sword pointed at the ground and looked like I was bored. Matt charged at me. I could tell he hadn't even improved a bit. I dodged every attack he sent at me. In a few seconds, he was tired as sweat was dripping off him. I sighed.

As Matt charged again, I sidestepped and held my foot out. He tripped, but as he tripped, I used my time powers to make everything seem slower and gave him around a hundred minor cuts. When he dropped to the ground, he was bleeding a lot. He screamed as he felt the cuts begin to eat away some of his flesh. The campers looked at me shocked. I shrugged it off and decided it was time to leave. Even though Matt was screaming, I held my sword at his throat. I was thinking of asking him to yield, but a better thought came to my mind. I kicked his face hard, and it hit the ground hard. He was unconscious before he hit the ground. I smiled and left the arena with Piper behind me. When we reached a clearing, I used the powers I got from Chaos and created a massive cabin for us. It was probably 5 times larger that the Zeus cabin, and it was even larger inside. I wouldn't actually call it cabin, but mansion would be a bteer word for it.
