Percy's POV

I was falling. I am falling straight into Tartarus and I am bored. You wanna know why? I've been falling for years now! Not years but that is how I am feeling. If Annabeth was here with m- No. I am just being selfish. I managed to throw her to the safety. Also I don't want her **there**. Actually now that I think about it how am I even gonna survive the fall? I don't think there would be any water down there. I am gonna die alone..One of my biggest fears. Dying alone. Will I even go to after life if I die down there? If even gods fear Tartarus then will Thanatos come down here to claim my soul? If Thanatos doesn't claim my soul then am I even gonna die? These questions flooded my mind as I was falling. What would happen if I died. No- I can't die. There gonna be a war and my friends need me. I can't fail them. What would they think of me. As I was falling I noticed a difference. The atmosphere was slowly changing to hellish red. As the atmosphere was changing I saw other changes too. For example I was seeing light down below. This was it I was gonna die. This is the end. Wait is that water I see down there? Ho- what?

I tried controlling the water. But something strange happened. I was not able to control the water. I tried again and again and again. But to no avail I still couldn't control it. If I can't control it then that means it is out of my dad's domain. And that means the 'water' will not slow down my fall. This was it.

"I love you Wise Girl" I mumbled. I probably won't see her again..Then I reached the water. When the water touched me I blacked out.

I opened my eyes. Where am i? Actually WHO am i? I couldn't remember a thing. I groaned as I sat up. I was struggling to breathe. It was like the air I breather in was poisonous. I coughed. There was blood coming out of my mouth. My lungs were hurting so bad. Also why do I feel like there is glass sticking around my body. As I looked at myself I realized that there was glass sticking out of my palm, knees, hands basically my hole body. It was hurting like hell. I pulled most of the glass out but there was still some glass sticking out of my body. Where did this glass come from. I looked around. There was glass everywhere on the ground. There is a stream to my right. Atmosphere is hellish red. Y-yeah I was right. It is definitely poisonous. I tried walking a bit but my legs gave up. They were hurting like a bitch. I decided sitting down. So I cleaned the glass a bit from the area that I was going to sit at and sat down. Now is the great time for thinking. How did I get here? Who I am? Why don't I remember anything? What is going on? I pondered on these questions but I couldn't find any answer to them. It was like my memories were erased. Gone forever. I decided to not dwell on it too much. Sure they were important topics but I needed to escape this..Place. If Annabeth was here with me then she would have come up with a plan easily. Wait. Who is Annabeth? It was like a part of my memory came back to me for a second and then just POOF. And it is Gone. I sat up and tried to come up with a plan. Keyword: Tried. Maybe if I went in one straight line I could get lucky and find an exit? That seems like a good plan. So I set off walking in one direction. After like 1 hour of walking I was so tired and hungry. I can't continue walking. I needed to eat something. My throat was dry. I needed a drink too. Coca-Cola and a cheeseburger would be nice. After some more walking I came across a cliff. That cliff dropped more than eighty feet that's for sure. He didn't really have a death wish but he can't just turn around and leave. First of all he can't really do that because well a lot of reasons. One of them being hunger. He examined the cliff. There was a tiny fissure running diagonally from the edge to the bottom. Maybe he would be able to climb down the ledge. I started climbing down the ledge. I was glad that I was not scared of heights. After some minutes I was at the bottom of the cliff. My hands were cut all over. Blood was spilling out of his hand. It was hurting like hell. He felt like giving up. He would probably die before he even finds the exit. But he decided that dying was not an option. Even if he was gonna die he will at least try to survive. So he started walking once again. After a minute of walking I came across a..River. Well if you can call it a river. It was made out of fire! Fucking Fire! Drink it, I heard in my head. Wait what? Did I just hear a voice in my head? Perhaps I was going crazy? Maybe from hunger? Perhaps from my tiredness. Even if the voice was real and I was not dreaming or something, drinking from a RIVER THAT IS MADE OUT OF FIRE!? I felt like I should trust the voice and do what it says but I don't really want my death to be like that. Drink from the river, Perseus. The voice revealed itself once again. Also, Perseus? Is that my name? I felt an urge to trust his words and go drink from the fire. Then I decided, Fuck it. If I don't drink from it I would die from hunger and tiredness. I was cut all over too. I stumbled to the bank of the river. Surprisingly river was not radiating heat. He thrust his hly and into the river and filled his hands with the liquid. The fire was not painful. It was the opposite. It was cold. The liquid felt cold in his hands. He raised his hand to his mouth and drank the fire-water. For one second he felt nothing. He was relived. But then he felt it. It was like his insides were boiling. His lungs felt like they were in fire. Which they were. His throat hurt like hell too. He started coughing. He never felt this much pain in his life. At least he thinks that way because he doesn't remember anything and this was the worst pain he felt. After a few seconds the burning sensation in his lungs and throat went away. He felt better now. Better than before. I sat up. Stumbled for a bit from the dizziness. I decided to turn around and leave this fire alone. Falling into a river made out of fire isn't ideal for him. After he turned around he locked eyes with someone. Or rather.. locked eyes with..something. This creature has spindly barbed legs. It looked like it was a spider. A big one. The creature snarled, then it lunged at me. On instinct I reached to my pocket and grabbed a..pen? from it? Next few seconds was blurry but the next thing I know I am covered in golden dust with a sword in my hand. Wait, where did the sword come from? I played with the sword a bit. I don't really know what I did but next thing I know the sword shrinked and turned into a ballpoint pen. The pen I grabbed from my pocket. So the pen could turn into a sword. Well that is interesting. "I need to learn how to turn this pen into a sword again or I am fucked the next time I face this kind of monsters" Perseus thought and started playing with the ballpoint pen in his hands. When he uncapped the pen and it turned into a sword Perseus jumped back. So that's how, Percy mumbled. He capped the pen and put the pen back to his pocket. Now that he had more energy he started travelling again. He only travelled a few hundred yards when he heard female voices. He hid behind a boulder. Maybe they know where the exit is, Perseus thought. The voices snarled. Getting louder as they approached from upstream. The voices sounded like a human. Maybe they were humans? Maybe they can help him? But he wasn't gonna risk it. Maybe they were monsters disguised in a human body. "Soon?" One of them asked in a raspy voice. "Oh my gods!" said another voice. This one sounded much more younger and much more human. "You guys are totally annoying! I told you, it's like three days from here." It was like he knew this voice from somewhere but he couldn't place his finger on it. There was a chorus of growling and grumbling. The creatures—maybe half a dozen.

"I wonder" said the third voice. "if perhaps you do not know the way, young one."

"Oh, shut your fang hole, Serephone," said the second girl. "When's the last time you escaped to the mortal world? I was there a couple of years ago. I know the way! Besides, I understand what we're facing up there. You don't have a clue!" Mortal world? What are they facing up there? And Fang Hole?

"The Earth Mother did not make you boss!" shrieked a fourth voice. Earth mother?

More hissing, scuffling, and feral moans—like giant alley cats fighting. At last the one called Serephone yelled, "Enough!"

The scuffing died down.

"We will follow for now," Serephone said. "But if you do not lead us well, if we find you have lied about the summons of Gaea—" Summons of Gaea? Who is Gaea? What is happening?

"I don't lie!" snapped the second girl. "Believe me, I've got good reason to get into this battle. I have some enemies to devour, and you'll feast on the blood of heroes. Just leave one special morsel for me—the one named Percy Jackson." Percy flinched. He doesn't know why he flinched but he did. Also what battle? This was getting more creepier every second.

The creatures shuffled off, their voices getting fainter. I knew that I need to follow them. They knew how to escape this hell.

I've been following them for hours now. I was tired again. I was beathing heavily. I am lucky that I am around 150 meters away from them or they would have noticed my breathing or the sounds that I was making while following them. Yeah I suck at stealth. While I was following them I decided to think about the stuff that happened today. At least I think it is today. There isn't really night or day here. How did I even get here. I couldn't remember anything but maybe I can remember small snippets of my memories. No matter how much focus I put into it I still couldn't remember a thing. Maybe it doesn't work like that? It was worth trying. What was the voice in my head? Did the "person" who spoke in my head put me here? It wasn't making any sense. Why would it put me to this place, then help me? Maybe it changed it's mi- Wait where is the creatures? "Shit" I thought. I didn't pay any attention to them and now I lost them. Maybe they were my last chance. Now I would fucking die in this place. Great! Just Great! But then they emerged from behind the rocks and 5 of them formed a ring. I was tired. I couldn't defend myself. Even if I was not tired I can't defeat 5 of them at the same time can I? 'Worth Trying' I thought as I drew the ballpoint pen from my pockets and uncapped it. I watched it as it grew into a sword. Man I love this thing.

"Percy Jackson," she cooed. "How awesome! I don't even have to return to the mortal world to destroy you!" Who is Percy Jackson? Didn't the guy who talked in my head that I was Perseus? At least it called me that.

"Who?" I said through raspy voice. The girl rolled her eyes.

"Where is your little girlfriend?" The girl which I guessed was the "second girl" growled.

"What girlfriend? I- I don't remember anything" I croaked.

"Don't play dumb with me Jackson" She said.

"Why are you trying to kill me?" I said as I took a step back. Apparently behind me was a cliff because I nearly fell.

"You have nowhere to run. I will take my revenge after you killed me two times." She snickered.

"I didn-" I was cut off by her lunging at me. I watched in horror as she raised her fangs. I was too weak to raise my sword. I tried to jump into the right. So I will not get injured and she will fall of the cliff. Unfortunately and fortunately she made huge cuts in my chest and she fly off the cliff. Fortunately I didn't die. I was injured pretty bad. I was in my laying on the ground. I couldn't do anything. My sword was not here with me either I dropped it when I jumped to the right. This was it. My vision started getting blurry I could make out the girl though. She lunged straight at me. I couldn't do anything. 3...2..1. I closed my eyes and waited for the impact. Nothing touched me though. I opened my eyes. The girl was frozen mid air. Everything was frozen around me. Or at least I thought so because my vision was so blurry. There was 3 flashes. Then some..chanting noises? Suddenly It felt like I was teleported to somewhere and I blacked out.
