Am I destined to be the villain?

A duel for the world and an end for a Villain

He was literally fighting inside his mind...it was like a battlefield had come into being,
"Now, let's settle this, you've harmed so many people, you killled and sealed everyone in the castle, and now you want to yet again harm my dearest. You will not get away with it, I have beat you once before. I can beat you again Vasileios."
"You fool of a man, how can you not see! With my help you could have anything you ever dreamed of! Any lady or man in the land- argh- you bastard!" Will saved no time, as soon as Vasileios started talking about replacing Nico there was an arrow sticking out of Vasileios's arm,
"Less talk, I'm tired of this, your the culprit...and truthfully my patience has been truly sucked dry. Now. Draw your weapon." Will spoke, his words calm and collected but stabbing like a thousand arrows,
"How dare you! I am a son of Poseidon! You will listen you damned son of Apollo!"
"I've grown tired of talking, draw your weapon or would you rather fight me without one. I may not know much of hand to hand combat but I'm sure I can win against a coward like yourself."
"You- YOU WILL NOT SPEAK TO ME THAT Way!"
Good. Just what Will wanted, that anger would add to his attacks making them sloppy and easily dodge-able,
"Stay still you whores son!"
"My mother may not be the best but you don't get to call her that!" There it was, that final shot,
The two exchanged hits, all will needed to do was wait for an opening but surprisingly even though his opponents attacks were clouded with anger he still held much force in each attack, as a Greek his attacks left little defense, so in a fight with someone who shared his skill it would be easy to trade shots, Will however did not have his battle experience or his strength,
But one hit at a pressure point and he could incapacitate him, no blood, he wasn't even sure if they could bleed, the two men exchanged many blows each one getting weaker and weaker, to Will it was apparent his opponent was running out of stamina.
Good. Only a little more and-
"what!?" Will thought, a dagger. Where did he get that from?! Hidden in his clothing was a dagger, he slashed upwards, it hit him, Will drew blood.
"Ha- haha all that talk was just for fun I guess"
Will knew it was a dirty trick but currently he was busy with more important issues like why his wound wasn't healing,
"Ahh... I see you've noticed my little daggers special effects! Well you see, this boy here...well, it has the added bonus on top of being able to shape shift of having a forever bleeding effect, it's quite interesting,"
'Shit. If I can't stop the bleeding I'm as good as dead.'
"Now why don't we start again!"
He was at the disadvantage, dodging while desperately holding his bleeding wound,
If only he could get a weapon, if only,
"What's wrong! Not so high and mighty now! Come one! Go for it! Hit me! Or are you too scared? Gonna cry to your mommy? Oh wait, your mother's not gonna come even if you do cry!"
Will knew what he was doing, he was trying to rile Will up, make him loose his composure, do a sloppy mistake and get killed, little did his opponent know he was fully prepared,
His memory was coming back and he knew something that his opponent didn't, that weapon was originally his past life's weapon, and if he spoke it's name. It would listen to its true owner, he just needed the right time, he just needed a good opportunity, and this was that opportunity,
He was forced onto the ground, the dagger within his reach, although it seemed like Vasileios had the high ground, in truth he was ten steps behind,
"Now, it's time for you to die and for me to kill your little fiancé and the rest of that camp. I always thought you were a coward for using such a ranged and different weapon but, perhaps this is something I can agree with you on. Goodbye Konstantinos." Right as Vasileios was about to drive the daggers point into Wills neck, Will spoke it's true name,
"Anatolí ilíou" the dagger illuminated, pushing Vasileios off him and back to the other side, the dagger had transformed into something worthy of a hero son of Apollo, though simple in design it's radiance could be felt by all who layers eyes on it, and the minute Will took hold of it, he could feel all himself regenerate, his powers, his strength all of it, and even his wound stopped bleeding,
"How. You. You can't, that name. You can't possibly have remembered!"
"I didn't, one thing you over looked Vasileios, my past self was a smart man, in those glass bottles in my room, was hidden a slip of paper, it told me the other side of the prophecy, and the name of my weapon, you may have strength but you lack in intelligence, you were so blinded by your greed you over looked too many things, and now the very weapon you sought to plunge deep into my heart will be the one to end you."
"No. This can not be! I planned for over a thousand years! It cannot be!" Vasileios yelled, lunging at Will, Will however dodged as swiftly and fast as light itself, before Vasileios could realize the dagger was only a few centimeters away from his heart,
"You-why, why do you not finish me dead, it is evident I have lost this duel, so finish me."
"As much as I want to finish you. You don't deserve eternity in Tartarus, no one does not even monsters, though you won't be able to posses people anymore, I'll give you a second chance, a chance to make amends, you'll stay at camp as a sword instructor, helping people, but just remember, I will always know what you do. So if you harm even a hair in anyone's head, I will come for you."
The silence didn't last very long, but it felt like that,
"I see, hahaha! Just as brilliant and cunning as always Konstantinos, I admit, I have lost, I will abide by your rules,"
"Good, now I think it's time I wake up and you get out of my body, also my name in this life is Will, Will solace",
"Yes yes, oh-it seems I'm being forced out as we speak, and it is good, greetings sir William Solace, thank you for this confusing yet appreciated sign of mercy. Though you may not know the extent of it, I am in your debt for showing me a good fight as well as the light of understanding, thank you."
On the other side, Wills body sat still, no more of the struggle, until,
"Nico! Look! Will he's getting up, everyone be ready for round two,"
Inside Wills mind it may have felt like a century but outside only a few hours had passed,
Will got up, and so did another figure,
Dark brown hair and gray eyes, he looked very similar to Percy, similar age but a lot taller, all of them realized,
That was the spirit,
"W-Will?" Leo asked very cautiously as he slowly lowered his weapons(ie his screwdriver)
"Hi guys um...sorry for the wait?"
"WILL!" Everyone called out, just glad their friend was alright,
"Will! You stupid idiot! I hate you! Your so stupid!" Nico could be heard in the back,
"I-Im sorry Neeks..."
"I-I hate you- Stop! Stop! What are you doing! Hey! That tickles! Put me down!" Nico shouted as Will picked him up and began spinning him,
Everyone seemed to forget the knew face,
"Oh shoot right, so...everyone, this is your new sword instructor, Vasileios! And also one of Percys half brothers!"
"No way we just fought this guy and now he is not only alive and ok but gets employed?!" Percy was let's say very very tired and done with Wills bullshit, everyone was,
"Yeah haha...sorry bout that, um...I kinda made a deal cause I don't really think he deserves to be sent to Tartarus...he's done terrible things but...no one deserves that...so I made a deal with him, if he stays here and does fine, which means no killing now hurting or harming anyone then he gets to live, and I think he has some words he'd like to say to Vivian,"
"Vivian."
"Vasileios."
"I-I am so sorry, I know nothing I say will change what I've done but I just hope, if you can't forgive me now you'll give me a chance to make amends for what I've done..."
"I-I like you said cannot forgive you, it will take centuries for all my kin to reform, but...I-I will give you a chance..."
"Thank you."
They all knew the scars of the past can never be erased but what's more they all knew for a fact that, they can always heal, as to not forget and forgive blindly but to forgive and give a chance to understand is to know and too know is the mist powerful weapon of all.
