Percy's POV

The next morning, I woke up from a good night sleep in three months. "It's the calm before the storm" I thought as I clean myself up and headed down to the kitchen for breakfast. When I reached the floor, I had the shock of my life. The kitchen was thrashed and it was in a mess. Plates were smashed to pieces and the table was overturned and the fridge was wide open. I immediately headed back up to my room and suit up. I went back down to the kitchen and started examining the mess. I found a note attached to the overturned table. It stated,

"Come if you dare, Perseus Jackson. See you on the battlefield soon. Thanos."

I gritted my teeth. He dares to attack the Mansion. I yelled,

"Jarvis, Assemble the team now. They need to see this."

Jarvis replied,

"Of course sir." With that, I looked back to the mess and wondered why Thanos would attack the Mansion first. I look up, my eyes showing dismay. I said to myself,

"He is targeting Olympus straight." Without waiting for the team to assemble, I went to the rooftop and fired the grappling hook, climbed to the nest building and sprint to the Empire State Building.

When I got there, there were people milling about, ignoring me. I walked up to the front desk and the bald guy was sitting there, reading a book. I said,

"600th floor."

He look at me and handed me the keycard wordlessly. I made sure that no one is entering the elevator and I entered it. I inserted the keycard and pressed the button and lean back and waited. Soft music was playing, but I was too worried to listen to it. Finally, the elevator stopped with a pleasant 'ding'. I ran out and saw that Olympus was fine, but I could not be so sure. I sneaked up to the throne room and enter silently. I hid behind a pillar and saw the Council in deep discussion. I eavesdrop on the conversation. I heard Athena say,

"...not doing well Father."

I frowned at this and wondered in my mind,

"Who are they talking about? If I stick around, I might hear something interesting?"

Zeus replied,

"If there is anything I can do to help her, I will. But the Fates overrule me. I cannot do anything."

Artemis cut in,

"But if we cannot do anything, Annabeth will lose strength and she is needed in this war." At this, my anger rose. They kept this from me. I said,

"You all dare keep this from me."

The gods gasps and look at where I am standing in the shadows. I walked out, Earthshaker in my left hand, emitting a faint white glow, and my right hidden blade was out to its full lethal length, glowing faintly. I said, my voice hard and cold,

"Why have you kept this from me? ANSWER ME!"

My dad said,

"Percy, if we can tell you, we will. But the Fates do not allow us. I am sorry that you have to find out this way, but we do not have any choice."

I grit my teeth and said,

"So, you are willing to see me suffer through the night for three months?! I have been having nightmares for the past three months and it is all about her body lying in front of the Doors and none of you appeared to comfort me?! The Avengers tried to help me through, but it was never enough. I need her, and you all just kept her hidden from me! Let me ask you, do the Avengers know about this?"

Hades (he has a throne on Olympus) said,

"Yes, they were sworn into secrecy by the Fates. They all tried to help you. We all try to help you. We're sorry if you have to find out this way, but the Fates did not allow us to tell you unless you found out on your own or until the war started."

I yelled, shaking the room.

"Even the Avengers know about this. I thought I could trust them. Turns out I was wrong." With that, I turn on my heel and storm out of the throne room. I walked to the elevator and entered it. Tears were running down my cheeks. My entire world was destroyed. The Avengers and the gods were only using me. The elevator door closes and I slid down to the floor, tears of betrayal running down my face. At the moment, I chose to return to Camp Half-Blood, now empty as the demigods are evacuated to Olympus, to think things through.

Zeus's POV

I sat on my throne, stunned. I did not believe that Percy was here. He must have something to tell us, but overheard on the things that we said. I said to Athena,

"Athena, get Annabeth and summon the Avengers."

Athena quickly sent an iris message to the Avengers and ran out to get Annabeth. A few minutes later, the Avengers (Yes they are allowed on Olympus as they themselves are demigods, Other than Thor of course) arrived and Annabeth stood with them. I said,

"Guys, we have a serious problem." And I told them everything that happened. When I finish, all of them were shocked. Natasha said,

"We have to tell him the full explanation. Do you know where he is?"

Poseidon replied,

"He is at Camp Half-Blood. I will bring you there." With that, the council adjourn and the Avengers and Poseidon disappeared in a golden light. Annabeth remained behind, her face having a sad expression. I walked over to her and asked,

"Annabeth, you ok?"

She shook her head and said,

"What if he hates me for not telling him that I am alive?"

I replied,

"Don't worry. If there is anything related to Percy that I know, is that he will never hate you."

Percy's POV

I stood on the rocks at the beach at camp. The wind was blowing, making my shoulder cape that is to cover my left gauntlet backwards, flying in the wind. I sigh, letting everything go. I thought about what the gods said. Maybe I was too impulsive when I was in the throne room. I thought about the Avengers. I don't hold anything against them. They were sworn into secrecy by the Fates. I close my eyes and open my senses. My ears picked up footsteps. I turned and saw the Team standing there, my dad was right beside them. I asked,

"How did you find me? I told no one of my whereabouts."

Natasha replied,

"Poseidon told us and he brought us here. Also we owe you an explanation and apology. We were demigods, nearing immortality like you, but we could not tell you as it will lower your chances of achieving godhood in battle. For that, we are..." That was when I interrupted,

"Guys, I don't hold a grudge against you. Maybe I was too impulsive back in the throne room, but I was pissed. But, now I understand, I could not see Annabeth until the war. But, no more secrets ok." That's when I heard,

"Ah, how touching. A pity it won't happen when I take control of Earth." I look up and saw Thanos standing in a war chariot, being pulled by horses made of hellfire. I glared at him and bellowed,

"There is no chance for you to rule here Thanos. Leave before we strike you down like the Avengers did before."

He chuckled and said,

"Ah how foolish Perseus Jackson. You are but a mere demigod. You can never defeat me. See you at the battlefield. That's where your final resting place is." With a laugh, he lashed the horses and took off to Manhattan. I cursed under my breath. But Tony cut in,

"Guys, we have company. Lots of it."

I look up to the skies and saw Thanos army. It was massive. The infantry divisions were roughly a million, and they were protected by at least ten thousand chariots per division. I cursed and said,

"No wonder the Fates said that we need the gods' help. This army is massive." With that, I activated the comms link built into my gauntlet, broadcasting a message to Zeus. I said,

"Zeus, we have an Omega level threat. Ready the Olympians. The invasion has started."
