Percy POV:
Ever since I left Canp Half-blood I felt like something bad is going to happen to me, I don't even know if I can complete this task without Annabeth,my girlfriend
Later Argus dropped me off at a train station then gave me a platform trolley with my luggage on top,I asked "Argus, if we're going to a school, then why do we stop here at a train station?" He gestured his hands as if trying to say that 'It's a mortal world, what do ya expect?, go to one of those trains'I got that message , then Argus left the station, left me so confused what to do next, they're so many un-answer questions in my mind: 'Why do I have to go alone?, What do I have to do next?, If this is a magic school then why a mortal station , et cetera
I signed them I walked in. I saw a family with red-haired and a dark brown-haired , just like in my dream, I watched them talking for a couple of minutes , then they run to the platform 9 3/4 , shocking me, I thought they would be injured I ran to the family and said "What?! Why did he do that? And where is he?!?" later, a woman with red curly hair told me "Oh dear, have you ever been to 'Hogwarts'? And what is your age? You seem to be older than Ron 4 years, how come you haven't to Hogwarts yet?" she said then I flustered, "Oh uhh..I...I'm an exchange student from umm...Hecate's magic academy" I lied "So my boy, My name is Molly, Molly Weasley, we'll come to platform 9 3/4 this is Fred" she said " He's not Fred, I am" he said " Sorry George , this is Fred" Molly told me "Mom, just kidding, I'm Fred not George" Fred said then chuckle with his brother "So..."I said "So have to run through the wall right?" I asked "Yes now by the way bro, what's your name" Fred or George asked(I can't tell that who's Fred and who's George) "I'm Perseus Jackson, Percy for short" I answered
"Well Percy bro you gotta run through the wall ,man"
Fred said "You go first, so I can watch how it's done" I said. Later Fred grab his platform trolley then ran through the wall I said "Okay, this is cool, can I be the next one? I said "Oh sure dude" George said "Well then, let'a go" I said then Molly was definitely winking at me. After that I ran as fast as I can through the wall, first I thought I was gonna crash but fortunately I didn't , then I walked in and enter the train, I thought to myself ' This is a mortal world, how could Hogwarts hide from them without any mist?' But then I thought again 'Oh...right...magic spells blah blah blah' Hope that I wouldn't meet any empousa or dracaena down here. I tried to find a room in the train to sit, I found one but suddenly I have a feeling like Annabeth told me to 'Find Harry and sit with him' , then luckily I found him, I knocked the glass-door and said "Hello,my name is Perseus Jackson, can I sit with you guys?" I said, feeling like I'm a kid introducing myself for a project in school "Sure, by the way I'm Harry, Harry Potter" he said. Oh gosh, this boy seems a bit weak, so I'll have to try my best to protect him,another girl said "My name's Hermione Granger, glad to meet you" she smiled then elbowed the red haired boy I saw him running towards the platform 9 3/4...He must be a Weasley "Hi Perseus" he said nervously "I'm Ron, Ronald W-"
"Weasley" I interrupted, blamed my ADHD "What? How do you know I was going to say that" He asked
"I saw your mother .Milliy Weasley"
"My mom,Molly"
"Right,and your brother,Greg"
"George"
"Right"
"And Fred"
"Right, and Fred"
I signed, again I muttered under my breath "Curse you ADHD" "So you have only brothers?" I asked non-curiously "Well, actually I have a sister,my younger sister, Ginny, and my another brother,the oldest brother,Percy ,just like your name" He said "Like Perseus?" I said "No" he answered me annoyingly
"Alright that's enough for chit-chat Ronald" Hermione said Then she looked at me "Why haven't I see you before?" She said, probably blushing at me(Though I didn't know why)"Cause I'm an exchange student from Hecate's magic academy" I lied 'smoothly', thank gods...they bought it, next time I have to thank Dolos for my 'lying skill' "Oh well, 8 hours left until Hogwarts" said Harry who had been so quiet this whole time "I'ma watch the views" I said afterwards they all nodded, after 8 extremely boring hours of sitting on a train, Harry said "Welcome to Hogwarts, and uhh what is your age you told me?" "About 18" I said "Woah bro, we're only 14" Harry said "Yeah..Well I would like to explore about Hogwarts after being in Hecate's magic academy for 6 years" I said flustering
"Alright the train stopped, let's get of here before we get in trouble" Ron said "Agree" said Hermione Then we walked into a huge gate, after that enter the school, a massive school, I found myself in a some sort of huge dining room? I guess..Later and old man, who I think he was very wise indeed, said "Welcome everyone I'm Albus Dumbledore, Professor Dumbledore of course, Welcome my children!, welcome to Hogwarts, school of witchcraft and wizardry, today we have new friends and family here at Hogwarts, also we have a great news! We also have an exchange student from 'Hecate's magic academy', now we will be sorting houses" He said then Harry gestured me to wait until he calls my name, I wait, for so long I thought my ADHD would explode,then finally "Perseus Jackson!"
Dumbledore said "It's just Percy" I said, he smiled , he whispered to me "This is the sorting hat, Percy, I know you're the son of Poseidon, Chiron told me, but keep it as a secret as long as you can my child, good luck" When he finished, the sorting hat said "Perseus Jackson hmm...Isn't Perseus the son of Ze-" I cover his mouth "Shut up! You'll destroy my cover!" I whispered loudly then the crowds started staring at me , whispering about me until professor Dumbledore raised his hand , everyone stopped, the sorting hat continue, "Hmm..Hufflepuff no..Ravenclaw  not so much...shall I put you in Slytherin or Gryffindor..hmm..so hard...well Slyth- no GRYFFINDOR!" , As I walked to Gryffindor dinner-table people was staring at me probably because I covered the sorting hat's mouth (Kinda disgusting actually) I'm glad that Hermione saved a seat for me "What was that for?" asked Ron "I don't know, I felt like he was going to tell my personal information" I lied "Well then, Percy, welcome to Gryffindor family" said Harry
Hermione POV:
Wow..Percy's handsome..well a bit..but I think he's a little suspicious, Is he a death eater? I'll ask him "Hey Percy" I said "Hmm?" Percy said , with still his food in his mouth (I literally have no idea why was he the only one with blue food) "Are you a death eater?"I asked "Death eater?, I have no interested in 'Eating Thanatos', what do you expect?" He said confusedly
"Oh" I said , but Ron and Harry was literally looking at me and shake their heads, later professor Dumbledore said "Alright everyone, time to go to your new house" then he waved his hand, all the food were gone
As we walked to our common room, Percy stared at everything as if he'd never seen these before
Every thing was pretty fine until professor Mcgonagall yelled "Perseus Jackson!" I thought 'oh, so he must be in trouble now' "Jackson, come with me, the head master would like to see you in his office" she said then Percy joined her and walked with her
Percy POV:
Oh gods..am I in trouble for covering the sorting hat's mouth? I hope not...then professor Mcgonagall said "Sherbet lemon" "Umm..sir would you like me to umm..get Sherbet lemon?" I asked before she could answer, the floor moved, It moved higher and higher, I started to understand that this 'is' Dumbledore's office, if Annabeth knew that I've just known , she would probably say 'Oh gods seaweed brain, you've just noticed?' then a few seconds later, I'm in a huge room,and I saw the sorting hat on one of the shelves , then Dumbledore came in "Would you mind if me and Percy would talk alone?" He asked , "No,not at all" Professor Mcgonagall said He nodded and Mcgonagall left the room. Is he going to send Annabeth here? Will he send Annabeth here? Is Annabeth going to be here? so many questions about Annabeth,wise girl until "Percy"  said Dumbledore , as I was thinking about Annabeth, I flinch, "Yes sir?" I said "My child,I called you 4 times" he said then I whispered something like "sorry", he smiled "Don't worry, but we need to talk about your 'water power', Percy, I need to warn you that some witches or wizards here can see, even there's Hecate's mist, so Percy, try not to use your power so often, okay?" "Okay"I said , then gave him a thin smile "Very well,good night Perseus" he said "It's Percy" I complained.
Then I walked back to Gryffindor's dormitory ,then I showered and sleep, again...nightmares...
In the dream, I was in Tartarus  again, but it was the scene that I was fighting Tartarus with Annabeth, Tartarus yelled "Hahaha funny indeed, you're in 'me', how could you possibly fight against and win?" he laughed "We could win this!"I yelled back and gasped in pain , I fell down to my knees "PERCY,NO!" Annabeth shouted, then I jumped and use my last power to fight Tartarus, Tartarus then yelled something "Percy, wake up!" but  I realized it was Harry's voice
Harry POV:
Oh no...Why was Percy sweating all the time and why he was shaking all the time? "Percy" I said to him gently "Are you okay?" I asked "Yes..yes I am ,Harry, and thanks for asking" he said "You should go eat breakfast, also get ready" I smiled, he nodded then I went to ' the three  broomsticks' and joined Ron and Hermione , I sat with them "Hey" I said "Um hmm?" mumbled Ron "I think something's wrong with Percy guy" I said "Yeah,I've been discussing this with 'mione, yesterday I saw Percy in the boy's restroom, he was washing his hands so it's wet right?" He said "And..?" "The problem is it should be wet for like at least half a minute but instead, his hands quickly dried after like a second" he took a breath and continued " Then I asked him"
'Why did your hands dried so quickly'
Then he simply replied ' what?, nah you must be imagining' then he walked off" Ron told his story
"May be he's a death eater" I suggested
"Yeah, I was thinking the same" Ron agreed
"But you might actually was dreaming Ronald,and besides that doesn't make him a death eater" Hermione replied "Well, you like hi-" "Ron! For the last time, I do not have a crush on him!" she said
"Whatever" Ron grumbled "Hey guys!" yelled Percy from far away "Thanks for saving a seat for me" he said happily "And-, wow! American food!" He grinned
"Woah woah woah woah, you're American?" asked Harry "Umm..yeah, didn't I tell you?" He said "No" Ron said "Okay..so I'm gonna eat k?" Percy said "Yeah whatever" I said then he eat, for some reasons his food were still all blue!, I guessed that yesterday day when professor Dumbledore told professor Mcgonagall to get him, he got his chance to asked him for blue foods
"Alright Percy, it's time for our first lesson" I said
Ron POV:
"Umm...guys" Percy said "Why are the girls's staring at me and making fun of me?" he asked then I rolled my eyes "Anyway" Hermione started speaking "Our first lesson is in Charms" she said "But I'm 18, aren't you guys like 14?" he said "True,true" said a voice behind our backs "Professor Mcgonagall" I said "Well,Dumbledore said that Percy's going to be attending some classes with you guys and some classes with 18 years old-classes" said Mcgonagall "Okay" he said then continue eating "But sir anyway, do you have like..books in Ancient Greek?, you know I can only read those clearly" he said "Certainly, Dumbledore prepared for you" she said "Oh okay great" he said "Your books will be ready in your classes, he's your lessons table" said Mcgonagall then she walked back to her room
"Dude" said Harry "What?" asked Percy "Why do you need to read in Greek?" asked Hermione "Yeah, I was thinking the same" said me and Harry "Umm..Well my father is a Greek and my mother is American" he took a deep breath and continued "But I can read or speak Greek better than English" he said "Well then can you speak something in Greek?" asked Harry, I knew he was suspecting Percy as a Death eater "Alright, Σου είπα ότι μπορώ να μιλήσω" "Okay" said Harry then narrowed his eyes then sent a message through his eyes 'This guy is definitely a death eater, seems like he's trying to cover himself as a Greek-American and talks in another language so we couldn't understand', I nodded
then Hermione lead us to charms class
Percy POV:
I signed , I wish Annabeth could see these amazing constructions I thought , later we walked to Charms class, the first thing Professor uhh I don't know whatever said was "Ah Mr. Jackson" said Professor I-don't-know then he raised his eyebrows as if reading my mind "I am professor Flitwick" he said "Now, would you like to show me some of your magic trick from Hecate's magic academy?" he said, then I panicked , but with no reason, I started speaking some thing like 'Ferula' then bandages started appearing
"Merlin's beard!" shouted Flitwick "Very good Mr.Jackson!, very well, so now, we're going to learn this spell, so open page 3" said the professor, yet the lesson was VERY boring since I've already known every spells "Hey" asked Hermione "If you're going to sleep, then you must know many spells, besides you should sit up and concentrate" Hermione said "Nope, it's boring" she looked angry then held me a half-torn piece of paper "Fix this if you're a 'genius' now" I groaned and a random spell popped to my head "Reparo" I said , then the paper started un-torn itself and fix it "Splendid Mr. Jackson" Flitwick said "Looks like- oh! Time is up! Bye!" "Bye Professor" said everyone in the class the we walked off except for me, I dashed off, I quickly ran to the boys to Harry and said "Hey bro, I'm still learning with you guys in defense against the dark art" I said excitedly but then Harry said "Hey, actually this year's new update is to break every classes , 20 minutes per break" Harry said "Great!" I grinned, I love to break
Afterwards , we walked back to our common room, we were talking and napping happily until a young man with pale skin, blacks hair, wears all back like he's just returned from a funeral, he has a skull ring on his hand and he was wearing a black cowboy hat (which was covering his face except some of his hair and chin)
"Hello Percy" said that young man, I flinched, then he continued "I've come here to check on you" he said, then removed his hat, it was Nico di Angelo, "Yo Nico" I said cheerfully "You know him?" asked Hermione "Of course we're friends" I said , "Would you mind if I talk to Percy?" Nico asked, behind him, it was Will Solace "My b-friend can introduce me and himself to you guys" "Boyfriend" Will corrected him then he waved me to follow him
"Dude, why didn't you bring Annabeth here to?, I would like to be with her" I said "She's on a another quest" Nico said "What quest exactly?" I asked
"Uhh I can't tell you now, but you'll know it anyway" Nico said "Chiron sent me and Will here to tell you about the 'triwizard tournament', it's most likely a contest of 3 schools, 1 per student, each one will be chosen by the goblet of fire which you have to write your name on anything then put into the cup, but this year Rachel said that it's not gonna be 3 students who passes the choosing section, there'll be 5 students who passes that" said Nico "Why is it interesting? "Yeah you'll get the Triwizard cup and 1000 galleons" he said "A thousand galleon is like 25000 dollars?" I asked "Yes, and I'll be staying here for like 4-5 days, exploring the forbidden forest" said Nico, he looked non-excited about going to the forbidden forest
"K bro I'm gonna return to the common room , in case if you need me, shadow message to me and does Dumbledore know about this?" I asked
"Yes, certainly, yes, Chiron contacted Dumbledore about this earlier today wait yesterday" he said
He signed "I wish sis,Bianca could live and see this" he muttered under his breath, sometimes he seemed like he got over Bianca's death sometimes he didn't, "Anyway did you guys visit Estelle?you know my half little sister? Estelle Blofis?" I asked "Not yet" he said "But Will has been wanting to" "So I guess bye?" I said
"Yes, bye,see ya later Percy" Nico said then gave me a thin smiled
