A/N, To everyone who is reading this Thank you. The Avengers should become part of the story soon, although it might be another chapter or two before that happens. I know this is very different from all the other stories I have written so far but I really wanted to try writing a dark Percy story and this is what I came up with. I don't normally ask for comments, but please let me know what you think of this so far.  now go ahead and read the chapter. 

Annabeth Chase remained unconscious for several days. Chiron and the demigods were starting to worry that they might still lose her despite what Apollo had done. Annabeth opened her eyes only to see bright lights above her. She quickly shut her eyes again and blinked a few times before she was able to keep her eyes open.

She could still feel pain all over her body, but it wasn't as bad as it had been after Perseus had first tortured her.

Annabeth could see she was in Camp Half blood's infirmary. She heard the door creak open and looked in that direction. She quickly recognized Chiron. A smile spread across the old centaur's face as he saw that she was awake. He walked over to her bed and stood beside it. He walked over to her bedside and looked down at her. "How are you feeling?" He asked.

She replied, "it's all still painful, but not as much as before,"

Chiron nodded, he'd expected something like that, after all, Apollo hadn't healed her completely, he'd simply healed her enough to make sure she wouldn't die. Chiron spoke again, "I do not wish to make you relive painful memories, but what happened to you Annabeth? Who did this to you?"

Annabeth grimaced and tears welled up in her eyes. The memories were coming back to her. She struggled to keep her composure as she began to explain, "Did you notice how Percy changed after we escaped from Tartarus?"

Chiron nodded before saying, "More than once I told him that if he needed help to come talk to me, he never did,"

Chiron had come up with a guess for who had hurt Annabeth, he was just hoping he was wrong. Annabeth continued, "Tartarus changed him somehow, and one night a while after the war ended I noticed Percy didn't go to the campfire. So I looked for him to find out what was wrong. After a while, I found him in the woods, but I could hear him talking to someone,"

"I eavesdropped on their conversation, and I quickly realized that Percy had turned against the gods and he was planning on leaving to join a new war against them. The person he was talking to was Khione. I was going to try and sneak away to tell you what I'd heard when Percy noticed me. I tried to talk to him to make him change his mind but he wouldn't. We ended up fighting. He defeated me and when he left he took me with him because he didn't want me to tell you all of this. He imprisoned me and that's where I've been ever since I disappeared,"

Annabeth mentioned how she had tried to escape a few times and that her punishment for doing so was torture. As she talked a few tears managed to escape and she would have wiped them away if she could have moved her arm. Her injuries prevented that. She kept on talking, explaining how it had been Percy who tortured her and why she thought he had sent her back to camp rather than just letting her die from her wounds.

Once again Chiron had a pained expression on his face as he learned that one of his favourite students had turned against the gods and how they would soon be fighting a war against him. Annabeth had also told him that it had been Percy who took Leo and that Leo was now imprisoned in the same place she had been.

A few hours after Annabeth explained to Chiron what had happened to her Perseus was at the base where his forces were preparing for war. Before him stood his spy from Camp Half-Blood. He was saying, "Annabeth told Chiron about what happened to her this morning. He announced that we will have a head counsellor's meeting tomorrow once Annabeth is able to get up and walk around more easily. She is still in a lot of pain,"

"Good, she deserves it, and It only further proves my point that the Olympians don't give a shit about us because Apollo didn't heal her fully before leaving,"

The spy asked, "Does she deserve it though? Sure she was going to snitch to Chiron but she's not evil,"

"Are you having second thoughts about what side of the war you are on? I could easily put your father back on the list of gods I plan to kill," Perseus said, irritated.

The spy replied, "No I'm on your side, I just think torturing her almost to death might have been a bit extreme,"

Perseus shrugged, "Perhaps it was but I needed those fools to see what I'm capable of, besides I'll put her out of her misery soon enough,"

The spy nodded, not questioning him further. Perseus said, "Now go back to the camp and come back tomorrow after that meeting and tell me what happened there. In your spare time, you should also try and get your sister on our side. I would rather not have to kill her,"

The spy replied, "I will,"

Perseus turned away from him and teleported away.

He reappeared in a large undersea palace, no it wasn't Poseidon's. Poseidon was no longer his father. He hadn't been since shortly after Perseus left camp. Poseidon had somehow found out that Percy had turned against him and the other gods. Because of that Poseidon had basically disowned him, taking away his powers and any other connection he had to the sea. For some reason, he had never told Chiron or the other gods about Percy betraying them. Perseus wondered whether it was because of arrogance. Perhaps Poseidon thought that once Percy was basically a mortal he would no longer be a threat. Or maybe he was ashamed that his son who he had once called his "favourite" had turned against him. Regardless, you are probably wondering how percy could go to this undersea palace if he was no longer Poseidon's son. The answer to that is because he was adopted by none other than Pontus and Thalessa. Not only that but when Hydros faded because he had been almost completely forgotten Perseus had been chosen to replace him as the Primordial of Water. Now Perseus stood before his adoptive father. Pontus said, "Are our forces almost ready to march?"

Perseus replied, "Yes father The war can begin very soon. We should be able to attack before the gods and demigods are prepared,"

Perseus asked, "Father How soon does Thanos plan on going after the stones?"

"About a month from now, maybe a bit more. He does not believe that he will need help to acquire them, but if the need arises he will call on you to assist him,"

Perseus nodded, He was not against the Titan's plan for the world. Sure many people would disappear, but why should he care? The only truly good people he could think of were his mother Sally Jackson, and his former stepfather Paul Blofis, but they had been dead for over a year now thanks to one of the many terrible people who inhabit the planet. The world needed to change, and perhaps Thanos's plan might help. Perseus knew that good people could also vanish, not just bad ones, but their sacrifice might be worth it if things turn out well in the end. Perseus had no intention of stopping Thanos, he didn't feel the need to.

The next day when it was time for the camp half blood campers to have their head counselors meeting, Annabeth Chase sat up in her bed. Her arms ached as she used them to help push herself upright. She turned herself so her feet hit the floor, her legs also ached in several places once she attempted to stand. She had already put on fresh clothes earlier in the morning, so now she was ready to go to the meeting. She knew she would soon be able to leave he infirmary and stay in her mother's cabin with her half siblings.

The entire time that Annabeth was attempting to stand, Will Solace was standing nearby in case she needed help. He had been shocked when she randomly appeared near the cabins, tortured almost to death. An image flashed through his mind, he was remembering how Annabeth looked that day. Her body had been covered in cuts, burns, and bruises, and her limbs were broken and bent in ways they weren't supposed to bend. Seeing her like that had horrified him. And he felt the same way as he remembered how badly hurt she'd been. Thankfully his father had helped so she would survive.

Will walked with Annabeth as she went to the meeting, he needed to go anyway since he was the leader of Apollo cabin. As the demigods all sat down at the Ping Pong table, you could say that they weren't happy campers as they waited for chiron to start the meeting. Many of the Campers were curious about what had happened to Annabeth, and who had tortured her. Annabeth had only told three people besides Chiron about what she had gone through. Those were Malcolm, Grover, and Piper.

Nyssa, who had been leading the Hephaestus cabin in Leo's absence, decided to speak up. She said, "Chiron, what is going on, first Leo disappears, and then Annabeth comes back almost dead, Is there going to be another war? Who's behind all this?".

Chiron grimaced before replying, "That is why we are having this meeting, there is going to be another war and one of the enemies we will be facing is Percy Jackson, although according to Annabeth he just goes by Perseus now."

Most of the campers gasped, and their eyes widened. Most of the younger campers were thinking of how they wished they didn't have to fight against someone who had once been their friend. Older campers couldn't help but think of Luke Castellan and the second Titan war. Nico Di Angelo feigned a look of shock, but he had known already that Percy had turned against the gods, and that soon he would lead the latest war against them.

The demigods' attention remained on Chiron as he continued speaking, "Annabeth, do you want to tell them what you know?"

Annabeth nodded before she began to speak, "I don't know who Perseus might be working with, but he most likely isn't starting this war on his own. He never told me much about his plans, but I know that he has gotten more powerful, and he might have become a god. I also know that Khione, the snow goddess, is on his side, because she is his girlfriend, and Perseus told me himself that he abducted Leo, and he is keeping him in the same place were he had me, "

"Where is that? Could we go rescue him?" Nyssa blurted, concerned for her half brother.

Annabeth replied, "No, I don't think we can. I have no Idea where the palace where he was keeping me is. I was unconscious when he took me there. I tried to escape a few times, but I never made it very far before he caught me," tears began to well up in Annabeth's eyes as she recalled the punishments that had followed those escape attempts.

Regaining her composure Annabeth continued, "I never even made it out of the prison floor. When Perseus sent me back here he did it using his powers so I've never seen the outside of the building or its surroundings,"

Nyssa's face fell, her hopes of saving her half brother had been dashed by everything Annabeth had just said. Piper and Jason also looked disappointed. Despite this they weren't ready to give up on finding Leo. Maybe they could still figure out where Perseus was keeping him.
