Prologue:
In the Japanese classroom of Fuyuki City's Homurahara Academy 3rd year class B, sat a tall, dark haired young man. Resting his head against his fist he stared out at the harrison, his green eyes half laden in thought over his current predicament.
You see, this young man was a person of legend. His very name struck fear in his enemies and brought hope to his Allies. He was the Fear of Monsters, Bane of Titans, Slayer of Kronos, Destroyer of Giants, Gaia's Blight. He was the Hero of Olympus, leader of Camp Half-Blood, former Praetor of New Rome. He led the very armies Olympus against her enemies. He is Perseus Jackson.
Just six month months before Percy and his allies fought against the very physical manifestation of the Earth, the primordial Greek goddess Gaia in a desperate war for the survival of both the Mortal World and the Eternal. They were are only armed with the prophecy of seven, their wits and past experience. They had destroyed Gaia's children the Giants, the Gods Bane's alongside their godly parents. Then they fought against Gaia herself in their final battle on the war torn slopes of camp Half-Blood. This was were in her last moments, she sought to leave one last devastating blow upon her enemies. She used what was left of her power in attempt to obliterate her enemy Perseus Jackson, her son's slayer. It was the ironic fact that very act of slaying Kronos, the reason of her hatred, was what saved him and landed in the place was now.
When Kronos was destroyed and his remains scattered to the four winds, his power exploded outward from his host encompassing everything in its way. A small taint of it was left on those who were closest, specially Percy who was standing only feet from him. So as Gaia's great power impacted Percy's form it mixed with it and activated the lingering power of titan lord and flung him into the void of time itself.
But time is like a web with interconnecting and branching timelines were anything is possible and do process left Percy exposed and undefended to any being with the power influence it. And that was what exactingly happened.
Alaya, the collective unconsciousness of mankind, the drive for survival, reached out and plucked him for use in its own devices. Now here, Percy Jackson stands in a new route on the path of fate as he strives to return home.
