Chapter Text

There was a tiny boy running through the fight at Hogwarts.

That was not a surprise itself to the great Lord Voldemort as there was a war going on and the seventh year students along with the staff and the Order were running around trying to stop him and his Death Eaters. No, what surprised him the most was that the boy looked to be around a fourth year at most. And he was wielding a silver muggle sword from one of the fallen suits of armor while waving his wand with his other arm.

Three werewolves were circling the boy, as though he was a delicious appetizer. Most of the others that faced him were dead, as though a mere boy could lure and kill all his werewolves. If he wasn't angry at the incompetence of his dogs, he could be impressed with the tiny boy.

Perhaps, if he wasn't a mudblood, he could be a fine recruit to his cause.

His mind set, he strolled forward from his place near the woods and entered the battlefield to cease his curiosity about the boy and punish the three– no, two – werewolves. He could hear gasps and cries of horror from around him and more than five spells thrown his way. He simply waved his wand and the spells dispersed, as if they were never there.

He stopped near the boy and the last standing werewolf. 

Fenrir Greyback, mayhaps recognizing his owner by his scent alone, stopped in his tracks and tensed up. Not taking his eyes off the boy for one second, he greeted his master.

''My lord, I was just finishing up'' he breathed the air in, licked his lips and smirked ''This little one has the most enticing smell. It reminds me of tales of old, of powerful kids to–''

''Gods, you lot never shut up''

Lord Voldemort raised one of his hairless eyebrows, placing the accent as one across the pond. Perhaps Canadian? Or American? Well, it didn't matter. Something that Greyback said caught his attention. Powerful kids? He looked at the boy again, his tan skin and green sea eyes never leaving Fenrir, even with a bigger predator close to him. Foolish and insolent but smart at the same time. But powerful?

The battlefield felt too quiet for a second but the moment passed. And he could see the questions in his followers eyes as they continued to battle.

''Greyback, cease it. A little boy should be no match for you and your pack but look at them now. Go elsewhere, I need a word with this boy''

Fenrir flared his nostrils again, too deep in his hunger for the American to obey.

''But, my lord…''

''Crucio''

The kid jumped out of the way but the cruciatus wasn't aimed at him. Greyback screamed and howled, like the little dog he was. He trashed around at nothing, his claws ripping his own arms to shreds. Lord Voldemort, as the merciful lord he was, granted him mercy.

Still enjoying the torture in the air, he didn't notice the boy moving as fast as a snake and plugging his sword in Greyback neck and retracting it in less than 2 seconds.

Lord Voldemort saw red and before he could even question it, he sent a cruciatus his way. The boy dodged again, almost getting caught by the proximity. Curse after curse, the boy dodged and continued to do so, creating a distance between them.

And curse after curse, the more calm Lord Voldemort became, sanity coming back to him slowly. No attack touched the boy and the battlefield became quiet once again to observe a moment or two of this one sided duel. He wondered…

In a moment of geniality, he pushed back against the mind of the boy. Entering a sea of memories, Voldemort found himself in a muggle camp for a moment, snarling at the kids for a moment but stopped in his tracks at seeing magic around. The air was filled with magic, even more than Hogwarts. Flashes of this place played around his mind in quick succession, a world of more raw magic and divinity than he even thought were possible were revealed to him. This boy, no, this demigod, would be his.

As quick as the thought came, the sea of memories swallowed him whole. He could feel a riptide shake him around, confusing, drowning and spitting him out on the walking world. Lord Voldemort staggered, almost falling to his knees before a flash of a Stupefy from the demigod wand hit him square in the face.

_____________________

Silence fell on the battlefield as Percy stunned Lord Moldyshorts.

He was tired, bloody and by his professor's faces, in a great deal of trouble but he didn't care. The werewolves that were ready to tear him apart because of his demigod's status lay dead at his feet, the dude that tried to curse him was stunned and some Death Eaters were running to help their snake-faced master. Professors and allies alike positioned before him and the rushing Death Eaters.

''PERSEUS JACKSON!'' yelled Professor McGonagall ''WHY DIDN'T YOU EVACUATE WITH THE REST OF YOUR YEAR?! AND–'' she stopped and went pale after finally looking at him.

Percy could imagine why. He was holding a blood soaked sword, he was surrounded by very dead, very gutless werewolves and he didn't miss the way she looked shocked at the sign of an unconscious Voldemort between them. The battle was still going on and the light of spells awoke her from the situation.

''Drop the sword and evacuate, we will handle… this'' McGonagall said as she sent a spell in the direction of a Death Eater.

''But I can still fight–''

''Evacuate now, Jackson!''

Dropping the sword but gripping Riptide at his pocket, he quickly ran in the direction of the castle. As he approached it, he saw his former Professor fighting one of the bad guys, still trying to go help his lord. Percy looked back at Professor McGonagall, noticing she was occupied and fired another Stupefy but now in the direction of the Death Eater. It hit his back, sending him to the floor.

Remus stopped his wand work, looking at him and snarling for a second like a farmish wolf before stopping himself and looking confused at his own reaction.

Ah, Percy tensed up, he forgot Professor Lupin was a werewolf. 

''Mister Jackson'' he looked around, before sniffing the air ''Please evacuate''

''Thank you, sir''

As he entered the halls, he signed a sign of relief. He didn't have a silver sword with him now and looks like Professor Lupin was a good guy after all, like Tyson.

Thinking about his brother, he quickly looked around the empty hallway. He should go to the Room of Requirement but his blood still roared for a fight. As he navigated the halls, he heard an explosion close by and tried and failed to not go after the source.

As he approached, he heard cries and someone shouting no's over and over again. He ran across the Golden Trio and two Weasleys, one dead and another he didn't recognize immediately. He tried to speak but curses flew from the hole created, hitting the hall behind the trio. 

Dam.

''GET DOWN!'' shouted Harry, him and Ron both grabbing Hermione and ducking ''PERCY, COME ON, WE’VE GOT TO MOVE!''

Percy looked around until he remembered that the redhead was also called Percy. He was holding his dead brother, protecting him from any spells that could hit the cooling body.

Percy looked around the scene some more, noticing the way a hairy leg was climbing slowly through the hole. He uncapped Riptide, ran and shouted.

''MOVE'' as he went in the direction of the emerging spider and stabbed it. Someone screamed and he didn't recognize who, he only had eyes for the spiders climbing through the walls ''IT BROUGHT IT'S SIBLINGS!''

He kicked the spider corpse through the hole. The body hitted some of the spiders, like a spider-sized bowling. Annabeth would have hated it. He almost shouted strike.

Harry, realizing what he was doing, went ahead and threw some spells towards the rest of the spiders, stopping all of them from climbing. More curses flew in their direction from the air, definitely flying Death Eaters, and he used his sword to block a nasty one.

Wide eyed, his ally looked at his sword, his wand and at his stature, definitely thinking what a growing guy like him was doing in a battlefield. Harry decided it was not the time or place to ask and said

''Let’s move, NOW!''

The other Percy was still clinging to the dead body. And dam, that was definitely Fred. Harry tried to hold Fred's body by his armpits while crouching down. Percy, him and not the other Percy, pitying Harry, sent a quick feather light charm at the body. The redhead Percy, realizing what was going on, quickly helped Harry carry the body to somewhere while Percy helped to block any curse that got close enough.

After depositing Fred behind a suit of armor and seeing the other Percy run away after a tall man, he was pulled along with Harry to a safer place. Which was a tapestry of some sort with the rest of the trio. He looked around, noticing that the two others didn't notice him yet because of the dark.

'' to me – LISTEN, RON!''

''I wanna help– I wanna kill Death Eaters—'' griefed the redhead in rage mixed with his pain.

''Ron, we're the only ones who can end it! Please– Ron– we need the snake, we've got to kill the snake''

Percy decided to say something for once.

''Hi''

Jumping out of their skins, the two tensed up before looking down at him. They only relaxed slightly, still distrustful of anyone besides their close knit trio. Hermione looked at Harry, clearly accusing him of bringing the kid in their secrets.

''Harry…''

''Look, I wasn't thinking and he is a kid. I couldn't leave him alone at the corridor even if he killed an Acromantula''

And knocked out Mister Snake-Face, thought Percy. As silence fell, he locked up, noticing the stares.

''Blimey, mate, you did what now?'' shock overcame Ron's grief. 

''Did I say it out loud?''

''Yup'' interjected Hermione ''And called Voldemort Mister Snake-Face''

''Dam'' said Percy. Then he looked at Ron ''Look, focus on whatever your quest is. You lot are the only ones that can do it by the looks of it. Grief, pain, step it aside for now because this is not the end, it is only the beginning. And until the sun goes up, we will hold the ground for you to complete whichever quest you were given''

Nodding at them, he took a step back ready to go.

''Not me though'' he huffed ''McGonagall told me to evacuate after seeing me stun Voldemort''

''Professor McGonagall'' stressed out Hermione ''But you won't be able to go through the Room of Requirement. It caught fire, fiendfyre''

''Well, looks like I will hold the ground too'' Percy said, smiling. They looked at him like he lost his mind.

Harry winced then, grabbing his scar. He looked pained and Percy looked at him, confused before remembering the rumored connection between the big evil guy and Harry Potter. Maybe the pain was a way of it showing itself?

''He is awake and furious. Bellatrix was close by, I think she awoke him…'' he furrowed his eyebrows ''He went flying to the Shrieking Shack… Nagini was there and he is looking for Snape… and a boy?''

''You, mate?''

''No, he said to Nagini it was a… what he called him? A demigod?''

Percy held his breath. How did Voldemort know about his origins… does mind reading really exist in the wizarding world? Did Voldemort invade his mind and saw who he was? He tried to remember his fight but he was only focused on surviving and going back to camp. Someone touched his elbow and he jerked back as if slapped. He looked up.

''Huh, were you listening?" Ron asked.

''Nope'' he popped the p ''I get distracted easily.''

''Right…'' Harry drawed, scrunched brows again ''Do you know something?''

''A little'' they looked at him, expecting him to elaborate. He didn't  ''I can't really–''

Before he finished talking, two Death Eaters ripped open the tapestry the four of them were in. One of them, opening their mouth to scream Potter, got interrupted by a punch Percy threw at them, knocking them out cold. The other, surprised by the physical attack, took a second too long to switch the direction of his wand at Percy.

A second he took full advantage of.

Grabbing the wand with his hand and snapping it in half, Percy headbutted the Death Eater hard enough to confuse them. The mask broke and the evil dude's nose got broken with it. He cried and got a stunning jinx on his back.

''Bloody hell'' Ronald looked at him with respect ''Never thought I would see muggle's brawling up front and being used on a Death Eater! He is going to be pissed at his wand's when he wakes up''

''Not my problem'' Percy looked at them ''We will hold the fort, go on''

The trio looked at each other, perhaps making a decision by the stares alone. 

''We never were introduced, did we?'' Harry said, almost softly ''Who are you?"

''Fourth year, Hufflepuff'' he smiled ''My name is Percy Jackson''

Harry was pretty sure the group's new acquired teen knew what a demigod was.

It was the way Percy got nervous immediately after the mention of him. The way he breathed way too late, almost like he was holding it in. And Harry? He could only pity whoever caught Voldemort's attention this time. He just hoped that Percy wasn't involved in some way, he was too young to be involved in whatever Tom’s had in store for the demigod.

Demigod, what a strange word.

He could guess the meaning behind the word demigod but he didn't know how anyone could be half God. Maybe Jesus? Was Jesus a demigod?

Before he could ask himself what the word actually meant, Hermione looked at him.

“Harry, you get the Cloak on” said Hermione “Never mind us–”

Harry threw it over all three of them, pausing to look at Percy that blinked at where they had stood. The boy looked at their disembodied feet quickly before looking up at where their heads were supposed to be.

“Will you be ok?” 

“Yes, I can hold myself alright in a fight”

“We can tell” Hermione looked at the blood on Percy’s hands a second too long “Be careful, Percy”

“You too”

Before he could say something more, the younger boy nodded at them and ran to battle. They soon followed after him, invisible to the eye, soon finding themselves in a corridor full of duelers with portraits screaming words of encouragement towards the students. The teen at the front barely stopped to assess the situation before blending in with the duelers, attacking any Death Eater that was too focused on someone’s else.

The trio moved and Harry could spy Parvati and Dean both with downed Death Eaters at their feet with the help of Percy. Before they could escape the chaotic corridor completely, they heard a “Wheeeeeeee!” from above, and he saw Peeves passing through, dropping Snargaluff pods at the Death Eaters.

Ron made a sound of pain as one of the pods had hit directly over his head, the green roots floating in midair, shaking in Ron’s effort to shake them loose.

“Someone’s invisi–” 

Before the masked Death Eater could finish the sentence, Percy jumped him from behind, quickly taking him out with a curse and a punch. For a moment, Harry could swear he and everyone focused on Percy before the two remaining Death Eaters tried to take the teen out in the next breath.

In a blink, Percy dodged the curses and fired two curses himself. Before anyone could comprehend what was happening, Percy moved and grabbed the wand of a masked Death Eater and snapped it in half. The second guy tried to gain control of his bearings and sent a Sectumsempra in the direction of the teen, who dodged it. The curse hit the other Death Eater in the chest and Percy jumped in the direction of the one who almost cursed him before punching him in the face and knocking him out.

There was silence in the corridor, blood dripping from the masked guy on the floor. Harry motioned for his friends to continue but he couldn't stop himself from wondering as cheers broke in the corridor behind them.

Where did they even find this kid?

_____________________

Percy was tired from jumping and dodging curses but he is fine.

He could do some water though.

The cheers stopped as more sounds of explosions and fighting penetrated the corridor. For some seconds, all he could hear was the distant cries of people battling for their lives. It reminded him too much of Zoe’s final battle in Mount Othrys. At least there he knew everyone who fought alongside him. 

And against him… but you can't look a pegasus in their mouth.

Before he could get lost in grief, a hand grabbed his shoulder. It was a seventh year Gryffindor student, Jean, if he was not mistaken.

“That was brilliant, mate. That punch? 10/10, would replay it again a thousand times” Jean exclaimed, smiling. “After this is all over, teach me, alright? Oh, I am Dean, by the way.”

“Percy and sur–” 

A loud sound was heard, almost like someone forced the doors open. Signing to himself mentally, Percy looked at Dean.

“We talk later”

Dean nodded, retreating to stay close to a girl from his house and year. The group of students looked lost on what to do now, many not looking at the blood soaked and very dead Death Eater. The ones that were alive were unconscious and uncuffed. He frowned, raising his wand and commanding magic, Mist itself, to listen to him, tie the remaining bad guys up extra tight and to grab their wands and give it to him. With a pocket now full of wands, he considered what to do with them now. 

Percy has already broken some wands since the battle started. Would the magical government punish him for that? Take away his wand? He could do magic just fine without it..

Mind set, he grabbed the wands and snapped them in half. He could sense the Mist vanishing from the wands, now no more than sticks. Percy threw the mistless sticks to the ground, making sure the Death Eaters would see them when they woke up. The students that stayed behind catching their breaths gaped at him. Some even murmured asking themselves if he was crazy. 

Whatever, what could they do? Sue him? For surviving and breaking some nazi’s wands? 

He heard more screams and raised his wand while his other hand instinctively grabbed Riptide in pen’s form.

Biting his lips, he went to battle.

“You have fought valiantly. Lord Voldemort knows how to value bravery”

Percy jumped at the cold voice. It was not the first time he heard Voldemort’s voice today but the high, unnatural way the sound carried itself was not easy to the ears. His godly side was sure there was something more going on with that dude.

He looked around, noticing the way everyone, even the Death Eater’s, had stopped their battles to listen to Mister Snake-Face monologue. Gods, was he using magic in his voice? Should he start to fight the distracted purebloods supremacists?

“...I command my forces to retreat immediately”

Like the command it was, the Death Eaters left in black smoke. Up and up in the air they flew. Percy almost prayed to his Uncle to blast them but no lighting came.

“To the demigod that defied me, I will come for you. Join me, show me the way to a glorious path where only magical beings remain. I will even spare your loved, magicless ones. Show me your gods and pray they are as merciful as me”

He blinked. Hades, he didn't have a second of peace, did he? Now he really prayed to any god to get offended and strike Voldemort's for such hubris.

"I speak now, Harry Potter, directly to you. You have permitted your friends to die for you rather than face me yourself. I shall wait for one hour in the Forbidden Forest. If, at the end of that hour, you have not come to me, have not given yourself up, then battle recommences. This time, I shall enter the fray myself, Harry Potter, and I shall find you, and I shall punish every last man, woman, and child who has tried to conceal you from me. One hour"

Almost like breaking out of a trance, the wixes started to murmur to themselves. Some were confused by the sudden lack of enemies to fight, others gasped for air and dropped to the ground. Others looked around for their loved ones, searching every face for someone they knew. He could see couples reuniting or couples torn apart by death. The staff were counting students and making sure the injured were treated and safe. The dead’s bodies were levitated to the Great Hall from any corridor and crack they could find.

It was following everyone’s steps that Percy noticed the actual contents of the murmuring.

“A demigod? Like the old, pureblood stories?”

The what stories now?

“Grandpa always told me the gods were real and lived in Britain…” murmured Neville “No one ever believes him”

He blinked to himself. Didn't Chiron tell him that England once held the flame of civilization? Did the gods interact with the wixes during their stay? Before he could muster courage to join the conversation and act like a clueless wizard, a sound to his left caught his attention.

It was Firenze, part of his flank soaked in blood and still pouring. He tried to stand, but his injury impeded him. He looked directly at Percy.

“One of The Seven” declared Firenze “A great honour, Perseus Jackson”

He wasn't sure what "The Seven" part meant but the way the centaur spoke made sure it meant a lot to him. And his full name… yeah, Firenze knew he was a demigod. Percy decided then and there to get out of close proximity of him.

“Pleasure. I have to go, someone I know is calling me”

He ran off to the row in the middle of the Hall. He only stopped when he was some feet away from Firenze and any talk about demigods. Percy tried and failed to blend himself in with the friends and family’s of the dead. He couldn't see anyone he knew in the row but that didn't mean much as the Weasley’s were close enough to where he was, mourning the loss of their son and brother. 

He didn't know them but he knew Ginny.

He approached her, cataloging the dead. A Gryffindor, an Order member, another Gryffindor. He bites his lips, shakes his head and looks at a tear-stricken Ginny. Her eyes are unfocused on her dead brother.

“Hey” Percy, supplied, as he does. Ginny focuses on him for some brief moments before looking at the dead again. At least she is listening, he observes  “It was fast”

Ginny looked at him now, fire in her eyes.

“What?”

“I arrived at the scene just in time to see him” he pauses, looking at the corpse “Fred Weasley died as he lived, laughing. He was happy to reunite with his brother and happy to hear him joke”

There is silence, more tears leaks from Ginny's eyes. She sniffs and looks back to Fred’s still body. 

“I bet he just arrived in Elysium” Ginny says “Bet he is having a blast right now, meeting his idols”

Nodding along, Percy tilts his head. Did all purebloods believe in Greek gods and he just realized it now? At least he knew Elysium and the Underworld existed by going to visit it once but the wix community only knew it through myths and some contacts with the gods then and there, he guessed.

“He will need a coin. And a burial shroud”

“Yeah, he will– wait, what” she blinks away the tears “You know that these aren’t used anymore for wixes burials, right?”

“How will he pay Charon, though?”

“Who?”

“Oh gods, this is why Charon wants a raise”

Ginny snorted but looked close to crying again a second later. 

“Merlin, I don’t even believe in the afterlife. I just hope he is happy wherever he is”

Percy bit his lips. He really wished he could say: Hey, your brother? Is on the waitlist of DOA Recording Studios. How do I know? I visited it and the Underworld once to confront my Uncle Hades and don’t worry, Elysium looked very nice.

Yeah, no way.

But instead he said:

“One day you can hug him again, Ginny. Believe in it and it will become real”

“You suck at this”

Percy remembers Nico Di Angelo eyes glaring at him. Is not hard to believe that he does suck at consoling people ( and keeping promises , a traitorous part of his mind tells him).

“Ginny?”

They both turn to look at the new arrival in unison. Hermione is looking at them with an expression of worry and tiredness that can be explained by her months on the run and her best friend being sentenced to death or to be hunted down. 

“Fred… he didn't make it” she touches Ginny elbow, sad eyes not focusing on the corpse but on the present “We didn't manage to save him from the explosion, I am sorry”

“It's not anyone’s fault” mumbles Ginny. She gets a hug from Hermione

“It is the Death Eaters and Voldemort’s fault though” he states “War is not gentle, it has no mercy to give”

Both girls look at him, exhausted and miserable. Perhaps even a little wary of his tone.

“Yeah…” murmurs Hermione “It’s their fault, isn't it?

They stay in silence for the dead, moving closer to the others. He isn’t sure how he will fare when the battle returns, he was lucky to live this far in it even if his godly blood makes him harder to be fought.

He looks to the side, seeing Tonks dead body and her husband, Professor Lupin, alive and filled with swollen eyes of crying. 

Ares has no mercy, indeed.

_____________________

Percy felt numb as he walked around the grass.

He could spy Ginny helping a girl, he could see Neville bending down to pick a dead body. He could see Harry, under his mist-filled Cloak, approaching the other gryffindor and removing the cloth to talk to him. Percy strolled to talk to them, catching the end of the conversation.

“Just in case they’re—busy—and you get the chance—”

“Kill the snake?” Neville asked.

“Kill the snake”

“Kill what snake?”

They both jumped at his voice, blinking at him. Harry hesitated.

“Kill Nagini” Neville said, furrowing his eyebrows, “Percy, aren't you underage?”

“Eh” Percy smartly said “Anyways, Harry, you doing ok?”

“I’m fine, thanks”

Silence enveloped them. Harry decided to walk away but Neville grabbed Harry’s wrist.

“We’re all going to keep fighting, Harry. You know that?"

“Yeah, I–”

Percy observes as the words escape Harry. Should he stop him from sacrificing himself? As he observes the Gryffindor walk away and get the cloth on top of himself again, he bites his lips. They all heard Voldemort’s announcement. Die at his hand or watch everyone’s die for him.

Percy knew what his own choice would be.
