Hello everyone! This is my first fanfiction so I apologize if it is a bit weird.

WARNING: Mentions of rape/torture/possible curse words. YOU HAVE BEEN WARNED

There may also be spoilers. I'm not really sure though. This takes place after Blood of Olympus. I DO NOT OWN ANY CHARACTERS OR SETS OUR ACTIONS (well kinda) OR ANYTHING RECOGNIZABLE. NOW ON TO THE STORY! :)

Chapter 1

Annabeth POV

"Olympians and Demigods!" Zeus thundered. "As you know the threat of Gaia is rising once more. Only this time, things are different. This time she has on her side the Titans, Giants, Monsters and Kronus himself to aid her. And this time, we do not have Perseus Jackson to save us."

I bowed my head, trying to hold back a few tears. Over 600 years ago about a week or two after Percy's half-brother Zach Danielson came to Camp Half-Blood, Percy mysteriously vanished over night. Nico and Hades have been searching the Underworld for signs of his sould but so far nothing. This leads me to hope that maybe he somehow gained immortality. But why he never came back is a question I don't think even Athena herself could answer. I looked up as Zeus continued speaking.

"In order to defeat this threat I have requested the Army of Chaos himself to assist us though it pains me to have to ask for help. Anyway, Here they are!"

We all turned our heads as hundreds and hundreds of people clad in black capes with black shirts, pants and boots walked in. I stared, mouth agape. A few though not many near the front had certain Greek symbols on the front of their shirts. There was an Omega symbol, and Alpha symbol and others. But there was one person with a star on their shirt. I wasn't able to figure that one out. I watched as they all stood in neat, strict formation as if waiting for an order. After a few tense seconds, the one with the Omega symbol strode forwards and began to speak in a voice that was eerily familiar.

"Hello Gods and Goddesses of Olympus. My name is Omega." I heard a few people snort at his statement. He either didn't hear it, or he ignored it. Either way he went on. "I am the son of Chaos, second most powerful person in the Universe." His mouth (which was all I could see) twisted up in a smirk as Zeus fidgeted in his throne after this statement. Omega cleared his throat and went on. "And the Leader of the Chaos Army." We all stood there in silence, taking in what he had said when my mother Athena decided to speak up.

"How can you be a son of Chaos?" Omega turned to face her, and remained silent until she began to squirm in her seat. With a smirk of satisfaction he said

"I was adopted." Athena nodded before asking her next question

"Who is your biological parent?" Omega's smile dropped immediately, and he turned hard and stoic as he said in a monotone voice.

"A God or Goddess in this room." I sighed internally, knowing my mother wouldn't be happy until she got a clear answer. As predicted she asked another question

"Which one?" At this Omega all but growled out

"Figure it out Goddess of Wisdom." He then turned to his troops and began barking orders

"Those of you assigned to Lady Artemis and her Hunters, transport yourself to where her camp is. Those of you headed to Camp Jupiter, head over there. The rest of you." He sighed and said in a somewhat sad voice "You're with me at Camp Half-Blood." All the Gods and Demi-Gods watched as Omega followed his troops out the throne room doors. For a moment he stood in the doorway as if wanted to tell us something. Whatever if was, he changed his mind and slammed the throne room doors behind him. All was silent until Ares muttered

"I hate him." I nodded. It didn't take much for me to hate someone, but I knew right then I hated Omega more then I should.
