Prologue:
After the war Percy felt bored, and useless, so he went to find help. First he went to Annabeth, who upon hearing him said that he was an idiot, and told him to leave her alone as she was busy designing a temple for Athena. As Percy, or Perseus as he called himself now, was about to leave Olympus, he walked into Hera, the Queen of the Gods.
Hera appeared to have seen his problem, and took him in front of the Olympian Council, who 'requested' to know what was bothering their hero, so he told them, everything that was troubling him. Surprisingly it was Ares who came up with the solution. By the end of the day the newly appointed Ambassador of Olympus, was on his way to the Palace of Hermes, so the god could send him to on his way to Alagesisa. Once there he met not only Hermes, but also his father Poseidon, the sea god, or so he thought, because as soon as he stepped into the palace, his father grabbed his shoulder, and flashed them to his own palace. Once Perseus regained his bearings, he found his father sitting on a comfy looking coach in a large sea green room.
Not waiting to be told, he sat down across of his father in a similar looking chair. Once he was comfortable, his father began speaking, and what came out of his mouth was not what he expected at all.
"Perseus, do you remember what happened on Mt. Saint Helens?"
Yeah, but what does that have to do with anything?
"Because you my boy almost unlocked the entirety of your power. You see when you were a child, you were very, very powerful, so much so that I had to do something about it, or else you would have burned up, and your body turned to ash. I of course could not allow that to happen, so I blocked them, only to come out in the most stressful of situations. The first time this happened, was when you battled Ares on the beach, the second time was in the Sea of Monster when you were battling Polyphemus, then again the third time when you lifted up the Sky, and then the fourth time. The largest release of your powers, when you blew up that mountain. That was when it changed, you for the first time released the all of your power and in doing so destroyed that binding. Due your nature as a child of the sea I could not place a permanent binding on your power, so I put in place a temporary binding, which would have lasted for about a month after your sixteenth birthday. Therefore I sent you to the island with Calypso, as she was the only one that could heal you at that time. Then as you were healing, and completing the quest, I thought of a solution, The River Styx, the only thing short of Godhood that could contain that kind of power. From there I influenced that Child of Hades to try and convince you to take a swim in the Styx. Now I warn you that the binding will release its hold on your powers sometime tomorrow. As to what you would be able to do, I'll leave up to you, but you should know that it will be a little uncomfortable, and you won't be suddenly super-fast or super strong, or have a ton of new powers. All that will come, but I would give it around three months before you can grace the world with that amount of power."
With that Perseus found himself ensnared in a bright gold light, and the next thing he knew he was in a crater on the forest floor next to a blue rock.
