Disclaimer: I don't own Percy Jackson that would be Rick Riordan.

This story's actual title is The Son of Neptune. It is a follow up to The Lost Hero. It takes place during the same timeline as the Lost Hero. In other words this is what Percy lived through while Camp Half-Blood went on that fateful quest to save Hera.

One amnesia can ruin your entire day.

I was sitting in the middle of a classroom, dressed in an orange shirt, ocean blue pants and absolutely no memory of how I had gotten there. My right hand was clutching a blue ballpoint pen so tightly it must have been a matter of life or death but I couldn't remember why. My body was poised for flight and even in my amnesia state I knew I shouldn't be here.

I was surrounded by a bunch of snickering kids with bored expressions on their faces, they were all dressed in the same ocean blue pants and a white shirt except for a girl and a boy in the corner. They wore camouflage pants and a purple shirt. The guy looked completely calmed with his surroundings but the girl kept moving her pencil from hand to hand, as if she couldn't decide how to hold it.

The girl noticed me looking at her and met my gaze, she had a pretty face but her eyes looked cold and calculating. The sound of a door opening made me turn to the front of the classroom and what I noticed made my hair stand on edge. It was a middle aged woman wearing a long black sleeveless dress. She looked at the classroom up and down till she saw me and looked disapproving at me, like I didn't meet her expectations or something.

The moment lasted a few seconds but it left a clear message in my mind, this was not a woman who should be ignored or forgotten. At that moment the bell rang and the classroom got quickly emptied. I just sat there not knowing what to do or who I was.

Then the two kids who I had been watching at the corner got up and moved to my place. They were short but fit with a determined look on their faces. They were wearing name tags that I had a really hard time deciphering out, although I didn't understand why, but I finally made their names out: Reyna and Bobby.

"Who are you?" The girl named Reyna shouted at me, she looked really mad bordering on the line of crazy. "What did you do with him?"

"I don't know what you're talking about" At that moment she started pointing her pencil at me like it was some kind of sword.

"I will only say it once… Where is he?"

"I told you, I don't know…"

"Bad answer kiddo"

Reyna moved incredibly fast at me, but my instincts and reflexes took over and I blocked her punch, threw her sideways and stood my ground.

"How…" Bobby looked taken aback at this unexpected turn of events and regarded me with a sense of respect as he helped Reyna to her feet. "Who are you?"

"I told you, I don't remember"

"Lies!" shouted Reyna while she charged me with her pencil. But as she charged she touched the eraser in the pencil and it turned into a two foot length sword made out of gold.

"Celestial bronze doesn't shine like that…" I said, not aware of how I knew it. But I didn't have time to remember how I knew this, Reyna was closing in fast and I was completely unarmed. Once again, a fraction of a second before she could touch me my instincts took over. I uncapped my ballpoint pen and it transformed into a sword that I felt I had used for years.

I blocked Reyna's sword easily, she must have been a skilled fighter, but blinded by rage her skill was unchecked and it was easy disarming her. Bobby stared in awe as I disarmed his friend and her sword clattered to the floor back in its pencil form.

I stood there uncertain as to what to do next when I heard a voice behind me.

"Finish her!"

Unaware to us during the fight, the mysterious woman had entered the classroom, or had she never left it? The shadows seemed to conceal her, like they were part of her as she walked up to me.

"Finish her!" she repeated more insistently.

"No…" I told her as I turned my sword back into a pen.

"No…? Then I will have to kill you too, along with these demigods, son of Poseidon" she snarled at me as she started to change.

Her skin changed into that of a snake, she looked like a giant cobra from the head down and she slithered as she moved, but from the head up her head looked more like an eagle, with a razor sharp beak for a mouth and intense red eyes.

"Wow you look like a mutant chicken" I said before I could stop myself

"Don't look at its eyes" Bobby shouted to me "It's a basilisk, its glare can paralyze you"

Only too late did I understand what he wanted to tell me, I looked up and gazed deep into those red hate filled eyes, and I found myself unable to move.

I started to drift into a pleasant sleep, but pain brought me back into reality. Reyna tackled me just in time to get me out of the way as the monster slammed into one of the lockers. It roared in rage, poisonous venom dripping from its fangs.

Bobby launched himself toward the basilisk using a sharp golden knife that he had managed to retrieve from his bag. He was clearly a skilled fighter, but the basilisk was too much for him. He retreated back to where Reyna and I were standing, swords drawn, facing the monster.

It was at that desperate moment that my instincts took complete control over my movements and I charged, point blank into the basilisk, I don't remember what made me do it, I guess I just didn't want to see anyone getting hurt. The monster hurled venom at me, strong enough to kill 20 men and especially enough to kill one demigod but somehow it didn't hurt me. I don't remember how I did it, but next thing I knew, I was standing on top of the basilisk's body, holdings its severed head in my hand.

Reyna and Bobby looked incredulous not knowing whether to show surprise or anger as I started to walk toward them.

"That was…so…"

"It was nothing" I said trying to shrug away all the admiration, but I still didn't know how I had done it.

"Stupid!" shouted Bobby. "You should have been disintegrated by the basilisk's venom" He shouted in admiration.

I just shrugged, not knowing what to say. I didn't remember ever fighting monsters but it felt so natural, my sword had moved so fluidly and easily like I had been practicing for this all my life.

I still didn't know who I was, but I didn't have time to dwell on that, the basilisk was starting to sprout another head and was starting to mend all its wounds, in a few minutes it would be back in fighting form.

"We better get out of here" Bobby told me "I don't like it, but it looks like you must come with us"

After exchanging a few words and learning that they were on a mission looking for someone named Jason, I agreed to go with them. Partly because I didn't have a choice and partly because I wanted to know who I was.

As soon as I agreed to go with them, the ceiling of the classroom got torn to shreds and inside came a boy riding a hellhound, wearing full armor and a golden lance. He cast a glance around and set his fierce eyes on me. He sent a mayor Uh-Oh chill down my spine.

Thanks for reading. Please review.

By the way, according to Percy, a Basilisk is an actual Greek/Roman mythological monster and not something grabbed from HP.
