A/N: This is my first try at writing fanfiction. It is a Percy going back in time story. Hope you like it. Reviews appreciated.

On a large platinum throne sat a 25-foot long man with a long black beard that reached the end of his sternum, with silver wings protruding from his back. He looked no older than 30, but his eyes gave away his age. His dark golden eyes held unfathomable experience and power, barely controlled under the surface. Near him, a sand hourglass floated as though suspended in the air, and a pitch black scythe was strapped to his back. He was watching what seemed to be the birth of a baby. His nephew was born today, and yet the smile he had did not reach his eyes. His golden eyes met the baby's bronze eyes and suddenly, he felt a connection. This infant was destined to have a modicum of control over his domain. And yet, instead of joy, he felt a sense of impending doom following this realization. His brow creased in confusion as he mused over why an innocent infant would scare him so much. For a moment, the thought of looking into the fate of the little one came to him. Before he could decide, however, the aura of the infant reached him. How odd, he wondered, the little one seemed to have an aura of immense power, and yet different than what the infant's siblings had. The primordial felt a taint of darkness from within the baby. The aura wanted to control everything, to rule over everything. Nothing would be superior to it.

The primordial had a decision to make; he had to decide whether or not to give a significant portion of his power over time to the baby. As the primordial of time, he was able to see the future. He didn't like doing this as it was against the ancient laws but the circumstances were too serious; the power of his domain was boundless, it could be used to change fate itself. He had to be sure. As he used his power to peer in the future, the truth became apparent. If a high portion of his powers went to the baby, the world would be doomed. The child would rule over all, his tyranny would never end. For the world to survive and flourish, the power the baby received over time would have to be minimal.

It concerned him still to think that should he ever wish to fade away, the child could claim control over his domain and the world would suffer. That cannot be allowed to happen. Pondering over the possible solutions, one struck his mind and he liked it. Yes..The world would need a Hero. It would need someone not bound by the Ancient Laws and yet capable of challenging those in power, capable of bringing change and peace to the world. One who would not abuse this power, but use it to help the world advance, to face threats to the world.

He kept sifting through the future searching for this hero until he saw the birth of a child millennia away. A pure, brave soul, he would face trials far beyond any faced by a mortal before him. He saw that the mortal would suffer betrayal from many but would never turn his back on those who needed his help. Such a mortal would understand his role and accept it without question. Still, as a mortal, his power over Time would be severely limited, and to prevent any mishaps due to the power manifesting, he would key it so that it would awaken only when the Hero's need for it would define the future of the world.

Having seen the future and believing it to be the best course of action, Chronus, the Primordial entity of Time, came to a final decision.

His nephew, the Titan Kronos, would never be able to claim control of his domain.
That power would go to Perseus Jackson and would awaken when all other hope is lost.

Several millennia later-

Percy struggled to keep the doors of the elevator, that connected Tartarus to the land of the living, open. Blood was seeping out from the numerous cuts and bruises on his body. The only thing that prevented him from passing out that very moment, was his companion in the Death Elevator. Annabeth.
He needed to hold on, for the sake of everyone that had helped him get so far. Bob, Damasen, little bob, they had all stayed back. He was sure his friends from the Argo II were on the other side of the Doors, holding the stupid button so that they can bring him and Annabeth back. He had to hold on.

The longest eleven minutes of his life passed by painfully slowly, and his arms started to go numb. Just before the Elevator reached the Doors, a sudden blast rumbled outside, jolting the elevator hard and they both lost their grip on the elevator doors. The doors flew open with a scream, and Annabeth fell flat on the floor, careening dangerously on the edge of the now open doors. In a moment of pure fear and desperation, he pushed Annabeth back into the lift, managing to get her safe. But as he started to slip through the doors, he lost his balance and fell forward into the darkness. His arms flailed to catch onto the elevator somehow, but his bloodied hands could not find any purchase on the floor or the doors, and he fell.

His tired body now freefalling, he started to lose consciousness. Right before his sea green eyes closed, the last thing he saw was Annabeth's face, shouting his name with tears on her shock stricken face, getting further and further away.
