A/N just a warning, if you didn't figure it out from the description and the prologue this is going to be a dark Percy fanfic so it's going to have a lot of violence, some swearing, and perhaps other mature scenes, so I might end up having to rate it as mature.  I just haven't decided yet how graphic it's going to be. As much as I don't want to dissuade any of you from reading my story, I also don't want any of you to accidentally read something you're not comfortable with. now I've warned you so read on if you want to.  Also, this story isn't going to stick all that close to canon. 

Leo Valdez had not been the first demigod to mysteriously vanish from Camp Half-Blood. A little over two years before Leo disappeared, Annabeth Chase and Percy Jackson had both gone missing on the same day. They had never been found and some wondered if Percy might have had something to do with it. In the months before his and Annabeth's disappearances, Percy seemed to have changed. He had gone from his typical cheerful self to getting angry and violent over things that he would previously have considered minor.

Unbeknownst to everyone, his time in Tartarus had affected Percy more than he'd let on to his friends. After his escape from Tartarus, he could tell the place had warped his mind leaving him almost a completely different person. Yet despite knowing this he found himself liking the change. For a while, he pretended to be the same old Percy Jackson who would do anything for his friends. In reality, he was no longer that person and Annabeth quickly noticed the change. Their friends had noticed when their relationship seemed to be falling apart, but none had ever found out why.

Leo was sooo bored, The only time anyone even came near his cell was to give him food and water. Although he was thankful that they weren't starving him he was afraid if he didn't get out of the cell soon he might just lose his mind. He wasn't even sure how many days had passed since he had been captured. He could only guess based on when his meals were brought to him.

He had seen the man who had abducted him pass by his cell a few times but the man had never stopped to explain who he was or why he had taken him. Leo had also heard the sounds of screams or crying emanating from a room further down the hall. Leo didn't want to imagine what was happening in there, and he didn't want to find out either. Despite that he had a guess for what might be going on in that room, he just hoped he was wrong.

Perseus was lying in bed next to the goddess who he had been dating for over a year now. He was pleased to be able to have some time alone with her since he had been extremely busy ever since the preparations for the war against the Olympians had fully got underway. Yes, Perseus Jackson had turned against the gods, and he had no intention of going back to them. They just used him and all their other children to do things that they could have just got off their asses and done themselves. Demigods were basically just servants to them. The gods tried to act like they cared, by helping a little occasionally, or with extremely rare visits, but in reality, they didn't care and Perseus knew that there were others who would be better rulers than they were.

Perseus smiled at his girlfriend, he thought she was beautiful with her black hair and brown eyes. Sometimes it was hard to believe that they had once been enemies.

Perseus kissed her, and she quickly returned it. Her lips felt cold, but he didn't mind, that was normal for her considering that she was Khione, the goddess of snow. It was her who had convinced him to abandon the gods and help to overthrow them. It hadn't taken that much convincing since he had already started to hate the gods and how they treated their kids.

Perseus sat up and commented, "As much as I would like to stay here with you, I should pay my old friend Leo a visit, I'm sure he is wondering why I brought him here,"

Khione nodded and chuckled before asking, "Can I come with you, I'm sure Valdez's reaction will be quite amusing,"

Perseus chuckled as well before replying, "Sure, his reaction to finding out that we are together will probably be even better,"

They both laughed at the thought of how Leo would probably react to everything that they were about to reveal to him.

The couple quickly got ready, using their powers to do so. Rather than walking down several flights of stairs they simply teleported down to the floor where Leo was confined. They walked toward his cell and found him eating. He must have realised they were there because he looked up from his plate.

"Hello Leo," said the man who had abducted him. Although he had a better view of the man's face Leo still didn't know who he was. He had a guess, but Leo doubted that he was right. Leo could see that beside the man stood a goddess who he had no trouble recognizing. He wasn't even completely surprised to see her with the man. What did surprise Leo, was the fact that they seemed like they might be a couple.

Leo replied, "Who are you and why did you bring me here?"

The man replied, " Ouch that hurts Leo, you don't even recognize your old friend?" after he finished his comment the man had a sinister smirk on his face.

Leo suspected that the guy wasn't really hurt, and he also wondered if his guess had been correct after all.

"Percy?" Leo said, still unsure whether he was right or not.

Perseus grinned, "I thought you could figure it out, although I go by Perseus now,"

Confused Leo asked, "Why I thought you didn't like being called by that name,"

Amusement evident on Perseus's face he replied, "Well, my name means to destroy, and that's exactly what I plan on doing,"

"So you are starting a new war against the gods,"

"It's not just me Valdez, there are many others who believe those arrogant assholes should be overthrown,"

Leo half expected to hear thunder rumble outside despite the thickness of the building's walls, but he heard nothing.

Leo decided to take a chance and see if he could get any information camp could use if he ever managed to get out of this place, Leo was nervous though, he remembered all too well what Percy was like before he left camp, he had changed dramatically from the cheerful, kind, loyal, and sarcastic guy that Leo had known during their quest on the Argo II.

"If you're so sure you can win against the gods then how large are your forces?"

"Do you think I'm an idiot Leo, why would I ever tell you that," He was clearly angry, and as he spoke Leo soon found out just how much. Percy had raised his hand Leo lifted off the floor and flew backward until he hit the back wall of the cell, he remained pinned there as it started to feel like he was being choked. Despite the fact he was finding it hard to breathe he thought of how what was happening reminded him of what Darth Vader always did to people in star wars. Leo didn't know how Percy was suddenly able to do something similar but Leo was pretty sure that the force wasn't a real thing.

Leo didn't think about it much though, as he was a bit occupied with struggling and failing to breathe. He barely managed to croak out, "sorry," before Percy kept him there for a couple more moments and then stopped letting him drop to the floor.

"I suggest you be more cautious about the questions you ask from now on Valdez, you should also avoid insulting me, or khione, you know what it would probably be safest to just not insult anyone here," Leo didn't respond right away because he was breathing in as much air as he could after he was deprived of it for so long. He was also kind of scared now, He hadn't known what Percy was capable of now.

"I think you scared him," Khione commented, amusement evident in her voice.

Perseus replied, " Good, He needed to know that I'm not the same weak fool that I used to be,"

After Leo was back to breathing normally and had found the nerve to speak again he asked, "So you're with her now? What about Annabeth?"

Perseus snorted, "that relationship was basically over when she and I left camp, she's still alive if that's what you were wondering, but she might not be for much longer. Whenever I'm in a bad mood and need something to take it out on I spend time with her,"

Leo's eyes widened as he gaped at his former friend, "You torture her!"

Perseus replied, "She noticed how much I'd changed, and she found out that I had turned against the Gods. She was going to go snitch to Chiron. Before she could though, we fought, I knocked her out and took her with me when I left. Back then I still cared about her so I tried to convince her to join me but she refused. I couldn't have her running off and going to the gods so I brought her here. She has tried to escape a few times but since she was punished for those attempts she hasn't tried again. Because she turned her back on me when I needed her the most after we escaped Tartarus I was furious with her, my anger and her escape attempts were what originally led to the torture, but I still sometimes enjoy punishing the bitch who betrayed me. I haven't done it in a few days though.

So Valdez, learn from her mistakes, don't try and escape, it wouldn't do you any good anyway. You wouldn't survive even if you made it out of this building,"

As if to emphasize his point a bloodstained knife appeared in Perseus's hand, Leo couldn't help but watch as Percy fiddled with it. He also wondered if the blood that stained the blade was Annabeth's.

Leo wondered why Percy didn't think he would survive if he escaped this place, but he hesitated to ask because he wasn't sure if Percy would even tell him. As Leo watched Percy made the knife vanish from his hand. Now that it was gone he removed his gaze from Leo for a moment as he turned and looked at Khione, Leo saw a smile form on his face, and he was surprised to also see genuine affection for Khione on Percy's face. Leo had started to doubt that Percy was still capable of having those kinds of feelings after many of the things that Percy had just said and done.

Leo was also surprised that Khione seemed to also have genuine feelings for Percy as well. Khione quickly kissed Percy and then she said, "I think you have scared him enough for now, let's go,"

Perseus agreed, and they were about to walk away when Leo said, "Wait,"

"What?" Perseus asked, irritation clear in his voice.

"Why did you capture me and bring me here?"

"Think About it, the gods use demigods like you to fight most of their battles for them, what would capturing one of their strongest children do for me? If you decide you would rather be out of that cell, and on the winning side of this war I would allow it, you would just have to swear on the styx not to betray me,"

Perseus and Khione walked away, leaving Leo to consider everything Perseus had said.
