Chapter 1: Escaping the Pit

The fall took longer than Percy expected. Annabeth had once told him that to travel down to Tartarus was an estimated nine day fall. Percy though that was a little shy of how long it actually took. In fact he would have guessed twice that. After a while it hadn't even felt like they were falling, simply floating in emptiness. But they both knew the truth. There was only one thing they knew for fact. They were going to die down here, and they would do it together. Then at last they hit the ground.

When he finally saw the ground below them Percy pulled Annabeth in close and rotated them in the air so he would hit the ground first. The crash knocked all the wind out of Percy's lungs but somehow didn't break any bones. Not that it made it any less painful for him. He could tell however that he had succeeded in preventing Annabeth from getting hurt much by the fall. When he could final breath again he managed to call out for Annabeth.

"I'm good. You?" she managed to whisper. He only nodded. With that their journey into hell began. They soon learned that pain didn't go away in the Pit. In fact every wound, no matter the size or severity reopened and the pain returned, yet they did not bleed out. It seemed that down here they had an endless supply of blood. The air burned their lungs like acid. It was as if the organs were trying to light themselves on fire. Then there were the hallucinations. It was like living in an LSD fueled haze. There were times when they knew they weren't sane anymore, but most of the time they couldn't even tell the difference between sanity and insanity.

The Pit seamed to feed off their fears, twisting them and forming new fears out of them. Percy was slightly afraid of Annabeth now and he could see the same fear in her eyes when she looked at him. Not that he could blame her for being scared of him. Much as he tried to tell himself otherwise he knew he was now more scared of himself than any enemy he had ever went up against. Something dark had awoken inside him down here, something he wished he never knew about.

It started a few days after they landed in Tartarus. For the days prior Percy carried Annabeth on his back, seeing as her ankle could not hold her weight for long. They had yet to see any monsters. Though the thought only worried them more. Then they heard a rustling just ahead of them.

"What do you think?" Percy asked hoarsely.

Annabeth lifter her head up from Percy's shoulder and gazed into the distance. "I can't see anything," she said at last. "And I am not hearing anything either."

"Must have just been another hallucination then," Percy said and pushed on. It was only a few minutes before the came upon Arachne. It was then that they realized distance was not what it appeared down there. The ceiling she drop down from appeared to be miles above them.

"What do we have here?" Arachne hissed, "Took a little fall did we? I am glad that I am the first to find you two. You will die together, that should give you comfort." The mother of spiders lunged at them. Percy was never sure where the impulse came from. Or why the though even occurred to him. All he could really remember was acting.

Reaching up with his right hand he held his palm out toward the monster. She froze floating there in midair. Percy could feel the blood flowing beneath her veins, and he smiled. There was a twisted evil laughter filling the air now as he began snapping each of Arachne's many limbs off her body. The spider made no sound as this happened however as every part of her was frozen, vocal cords included, and unable to move. He realized the laughter that was filling the cavern was his own.

"PERCY STOP!" Annabeth screamed. He didn't know how long she had been trying to break through to him, or when he had dropped her, but from the sound of her voice it had been a while. Looking back at her he still had the twisted evil grin on his face. "Percy, please," Annabeth begged with tears in her eyes.

You could kill her with those tears, a voice whispered in his head. That was the though that snapped him out of it. Arachne fell to the ground finally able to scream in agony. Percy took a step back as horror took hold of him.

Before they could register anything else though a gleaming golden spear jutted out of Arachne's skull and the Mother of Spiders turned to dust. A deep voice rumbled over them then.

"Hello Perseus Jackson," said the former Titan of Mortality.

Just by looking at him Percy knew that the Titan had somehow regained his memories. "You remember don't you?" Percy managed.

"What? That I am the Titan of mortality, pain, and the West?" Iapetus said with a raised eyebrow. Percy was too stunned to move. Looking down at the dust that had once been Arachne he added, "Oh and violent death, though I must say you did quite the job without me. He walked over to Percy and Annabeth. With surprising gentleness he picked up the two demigods and said, "Yes I remember. Now come monsters return quickly here. We must get you to out of here as soon as we can. I am here to see to it that this happens. You are far too important to be trapped in this place.

Over the year that followed the two demigods became rather close to the Titan. He helped them find their way through the Pit and even offered to help defeat his mother, though the idea of that disapearred as time went on and they realized it wouldn't matter now that they had been stuck in the pit for a year. He admitted that he was at first mad at Percy for erasing his memories but had since come to terms with it. He even went so far as to thank Percy for giving him the chance to become something better than what he had been in ancient times. He also protected Percy and Annabeth when the evil in the prison became too much for them to handle. As the Titan of pain he was more resistant to the power of the pit, even helping the demigods learn to deal with the hallucinations more easily.

All things considered everything was going rather well for the trio. That was until Hyperion showed up. When he did everything changed. That was the day the world began to end for Percy.

He came in the middle of the night, or at least what passed for night down here. Percy and Annabeth were sleeping while Iapetus stood guard. Hyperion snuck up behind his brother and struck him with such force that it knocked the titan unconscious. He then captured the demigods and took them deep into the depths of Tartarus, away for their protector.

In the lair Hyperion had created for himself he began to toy with the two demigods. He would take turns torturing one or the other of them while the other was forced to watch. Several times Percy was tempted to use his newfound ability to control all liquids to free them. But he did not think he would be able to control himself and was scared of what he would do with that power.

One thing Percy did come to notice however was how much Hyperion seemed to enjoy torturing Annabeth. During one of the more brutal days Percy had even pull against his chains with such force that he broke his left arm and dislocated his right shoulder. Slowly the things Hyperion was doing to Annabeth got more and more vile. Then came the day that he crossed the final line. It was the day the last bit of restraint shattered within Percy. It was the day Hyperion raped Annabeth.

Percy was forced to watch as the titan performed the unspeakable act.

When Percy's rage broke the whole of Tartarus felt it. Even the mortals in the world above felt him unleash his anger as the earth quivered. All Percy could think about though were Annabeth's screams as they tore more pain into him than anything else had.

The sea cannot be restrained. His father's words rang out in his mind fueling his hatred for the Titan of the East. With a roar he shattered the Celestial Bronze chains that bound him to the wall opposite Annabeth and Hyperion. Turning at the sound Hyperion gaped at the Son of Poseidon.

Percy through himself at Hyperion fully intending to rip him apart with his bare hands. With greater speed than Percy could contend with in his wounded state Hyperion drew his sword and slashed. Scarlet filled the area as a gaping wound opened just over Percy's heart. Hyperion drew a dagger from a table next to him and lit his hand on fire. The Celestial Bronze blade turned white from the heat of Hyperion's flame. The Titan then drove the blade into Percy's already broken arm. Twisting and turning the blade as he continued to slice through Percy Hyperion let out a monstrous laugh and yelled, "Now I have my revenge sea scum!"

Hyperion withdrew the dagger and was about to finish the job when with a tremendous crash the Titan was slammed away from Percy.

"RUN BOY THE DOORS ARE CLOSE AT HAND! RUN!" Iapetus bellowed. Quickly running over to Annabeth Percy froze as looked at her.

She was beaten and bloody. Her cloths where shredded and she was curled into the fetal position crying. "Wise girl," Percy said approaching her slowly so as not to frighten her. She looked at him with pain and fear in her eyes. Percy pulled off what was left of her shirt and gently placed it on Annabeth.

"NOW IS NO TIME FOR MANNERS BOY. RUN!" Iapetus bellowed as he continued fighting his brother.

With a grunt he pressed his right should into a wall and forced his shoulder back into place. It wasn't the best job in the world but it would have to do. Percy reached down and lifted Annabeth just by her armpits. Realizing who he was Annabeth tried to support as much of her weight as she could and they began a slow stumbling run away from the scene of the battle.

Slowly the pain of their wounds seemed to lessen and Percy knew they must be getting close. The problem was he was also starting to get light-headed from the blood loss. Suddenly two miraculous things happened. First, the sounds of battle disappeared. Second, there was a sudden burst of light as something in front of Percy began to open.

"TRAITOR," Hyperion yelled in the distance.

Someone was running to catch up with them again. Even though Percy could tell by the sound that it was just Iapetus he sped up. They were so close now, and even if Gaea was waiting to kill them on the other side of the Doors of Death it would be better than remaining here.

Titan of Mortality caught up had caught up with them now and in one swift motion scooped up the demigods and picked up more speed. The doors were now fully open and the sounds of another battle could be heard in the outside world.

A boy appeared in the doors and under different circumstances Percy would have smiled. As it was he didn't think he would ever smile again. Seeing the trio coming Nico jumped out of the way as Percy barreled through the door as they came through the door. What they saw froze rooted them to the spot.

In Nico's had there was a golden scepter and legions of undead solders fought against monsters and giants. Frank could be heard bellowing orders to the skeletons as he and the rest of the seven fought an army of well over five hundred of the foulest monster Percy had ever seen. They could see four giants leading the enemy army.

The giants ranged in height from thirty to sixty feet. The largest giant had had green legs and hair and Percy knew at once, from Jason's descriptions, that this was Porphyrion. Then there was a forty foot tall giant with bronze legs and hear that was like the flames of the sun, "Molios, the Bane of Apollo," Iapetus whispered seeing where Percy was looking. The giant next to him was thirty-five feet tall. Its eyes were silver like its legs but this giant was completely bald. "Aigaion, the Bane of Artemis," Iapetus informed. Then there was the strangest giant in the group. He was thirty feet tall with golden scales. His head was that of a lion with a main of wheat. He had the arms of a bear, the torso of a man, the legs of a dragon, and the tail of a horse.

"Leon," Iapetus said for the last time, "The Bane of Demeter."

Just then there was a blinding flash of light. When it dimmed Zeus, Apollo, Artemis, and Demeter all stood in front of him weapons drawn. Iapetus set the demigods down and Percy collapsed to his knees as the lightheadedness got worse. The gods launched themselves into battle with the giants and their army.

All Percy could do was think, I'm dying. Leon slipped around the distracted gods now towered over Percy, Iapetus, and a now unconscious Annabeth.

"You two shall have the great honor of being our sacrifices, demigod." The giant's voice was ludicrous. Unlike his brothers who all had deep threatening voices Leon's voice was a high squeal as if it were an excited little girl talking instead of a thirty foot tall male giant.

In his delirious stared Percy heard himself taught the giant, "You never hit puberty did you?"

The giant made a noise that must have been a roar but sounded more like an elephants trumpet. Percy pulled out Riptide and tried to hold it out in front of him but he didn't have the strength to lift the blade. Iapetus reached around and grabbed Percy's arm holding it up as he through his spear at the giant's feet. Leon stumbled and fell toward them. Percy's sword pierced the giant's chest just as a golden sword-tip sprouted out of Leon's face. The giant turned to dust revealing Demeter.

"Hm," Demeter hummed, "I remember him being tougher." Without another word she turned to help her family.

"We have to close the doors," Iapetus said. It was true. Even with the gods here helping with the fight the monster were returning so quickly that it didn't seem to matter.

"How?"

"Someone will have to sacrifice themselves to lock the doors." It took Percy a second to comprehend that.

"What no…"

"I am the perfect candidate Percy. I am a titan that will only make the seal that much more powerful. The doors will never be able to open again. Do me a favor though will you?"

Percy nodded, "Anything."

"Don't forget what it means to live. And tell my mother… tell her from me, this was for my father."

Before Percy could say anything more the titan ran back to the Doors. Percy watched as the Titan began to glow. It drew the attention of everyone and for a second the battle was frozen as they all watched the Titan of Pain. Markings began to glow around the door and with a final explosion the titan was gone and the doors were seal. Percy's friend Bob was gone.

Then at last he fell into unconsciousness.

WHEN Percy woke he found himself in a dimly lit room he didn't recognize. Standing around him were three figures and lying next to him was another that he could tell was Annabeth. . He didn't stop to think he just attacked. He had to protect them. He grabbed the closest to him and pined them up against a wall by their throat. He felt the other figure put their hands on him and he swung the first like club sending them flying. They got back up and came at him again.

"I'LL KILL YOU ALL!" Percy scream, his voice seeming to shake the area around him.

He thought they might be saying something in return but he didn't care what it was. He wasn't going to let them get anywhere near Annabeth. He reached out with his leg and kicked the smaller of the two figures back into a wall. He still had the one he used as a club clutched by the throat in his right hand, he could tell that this was a female monster now. He lifted them and through them with such force he heard something crack when they hit another of the walls. The largest figure rushed at him seeming to almost change as it grew closer.

Percy rushed to meet the beast. Raising his right arm up to the air he drove his elbow down into the skull of the beast he head a bear like roar of pain. He remember the two bear twins Luke had once had following him and figured this must be one of them. He grabbed the monster by its fur as pain shot through his left arm, but he ignored that for now. He would have to deal with that later. Lifting it up into the air he swung it around and down onto the foot board of the bed. The bear let out a human like scream of pain.

Percy heard the one of the others coming up behind him and twisted around to deliver a massive uppercut that sent the monster sprawling onto the floor. Percy leapt onto the monster chest and began to punch the creatures face with as much force as he could. Something sharp pierced through his left arm and he looked down to see a bone was now sticking out of it. The monster tried to rise and with his right hand he slammed monster head back into the ground. It was the small one again he realized. He grabbed the monsters hair and used it to pull the beast's head back up and drove it back into the floor.

Before he could repeat the process a door open. Percy caught a glimpse of a man wielding a golden trident rushing into the room. There was a flash of gold, a sharp pain in his forehead, and the world faded to black once more.

Poseidon came rushing into the med-bay of the Argo II with Frank, Nico, and Hazel floating along behind him. Frank was the only one who was still conscious, but there was a small trickle of blood coming out of his mouth.

"What happen?" Piper gasped.

"Percy woke up," Poseidon replied

"Okay, but what does that have to do with these guys?" Piper asked her voice thick with worry.

"Percy did this to them. I am afraid that the Percy who went into Tartarus isn't the same as the one who came out," Poseidon replied.

Piper watched as the God of the Sea took the three demigods deeper into the med-bay to join Jason and Leo. Hopefully Apollo and Asclepius would get them all healed up soon.

The next time Percy woke he was chained down to the bed. Annabeth was still next to him and while she had a set of chains binding her to the bed as well, it was far few then what bound Percy. She was still unconscious. He tried to sit up but the chains prevented him from making much progress. He could feel that his wounds had been heal though so he at least had that going for him.

"I talked them into keeping you guys in the same room. I figured you could use that after…whatever happened down there."

The voice scared Percy so bad that a one of the chains binding him broke. His instincts told him to attack but in the back of his mind he recognized the voice and held back.

"Calm down," the girls whispered. There was something about the words though that seemed to carry extra weight. Despite himself he felt his body relax. Turning his head around him he saw a ragged looking Piper in the corner. "Sorry," she whispered. She sounded distant and worried.

Percy looked at her in confusion. They had been in Tartarus for a year, the rest of the seven should have been long dead by now.

"What happened, where are the others?" Percy asked desperately.

"In the med-bay. Don't worry they are all alive. Though you did quite a number on them."

"What do you mean, I did a number on them?"

"You don't remember?" Piper asked raising an eyebrow. Seeing Percy's look of confusion on Percy's face she began to explain. "After your friend sealed the Doors we were able to push Gaea's army back a little. Artemis and I managed to kill Aigaion. Apollo and Leo killed Molios. But when it came to Porphyrion, well we ended up retreating. We had to get everyone out of there while we still had a chance. You, Annabeth, Jason, and Leo were hurt. So the gods gave us a chance to escape.

"You woke up in here. Frank, Nico, and Hazel where in here keeping an eye on you guys. You looked so bad when you came out of that place. We were scared that you wouldn't make it so Frank was doing what he could to make sure you stayed alive till Apollo and Asclepius could tend to you. Nico and Hazel came in with him to keep an eye on your life force.

"When you woke up… you attacked them. You nearly killed Nico and Hazel. Frank was still conscious when your father brought them into the med-bay. If it wasn't for him they would all be dead by now. Why would you try to kill your friend's Percy?" She finished her speech accusingly.

Percy stared at her for a moment. He had been glancing at Annabeth every now and them but for the moment he focused on Piper. His eye were different from what the Daughter of Aphrodite remembered. The playful, mischievous, light that she remember was gone. Now they looked almost fractured. It was like Percy was constantly teetering on the edge of going completely insane. She understood then what Poseidon had said about Percy being different and the idea of Percy being the way he was the first time he woke up frightened her. His eyes didn't seem to show any remorse for hurting his friends.

"I…" Percy began as flashes of what had happened came back to him. He struggled with his chains for a moment then stopped. He looked irritated now. "I didn't attack them. There were monsters here that was what I attacked. I couldn't let them harm Annabeth. Not this time. Not like before." He looked extremely agitated suddenly he shifted under the chains as one of them broke. Again he stopped.

"What happened to Jason and Leo?" Percy asked suddenly as his eyes snapped back to her. There was a dangerous light in them now. A light that frightened Piper more than anything she had ever seen.

Piper took a breath. "They're alive. They aren't sure if Jason is going to make it." He voice cracked at the end. Percy might have tried to comfort her if his chains would have allowed it, but he wasn't sure about that. Percy looked back to Annabeth again afraid she would just disappear and he just couldn't live with that.

"We are on our way to Olympus, now. That is where the final battle will be."

"Is she," Percy began.

"She's fine. Apollo healed her leg. He said that since the initial injury occurred outside the Pit it could be healed. He took care of your wounds as best he could but some of the healing is going to have to take place on its own."

Finally Percy asked the question that had been gnawing at him. "How are you guys even still alive? I mean we have been down there a year. Have you guys just been floating around up in the sky all this time waiting for us? Did you really turn you backs on everyone like that?"

Piper looked at him strangely as she was walking to the door. She looked as confused by his question as he was by her still being alive. "Percy," she said slowly, delicately almost, "You were only down there for two weeks. We still have two more before Gaea has risen."
