The Iron Revenant of Zero

Chapter 1: The Summoning

Tristain, Halkeginia

In the country of Tristain there located a prestigious school for talented mages, Mages that also are Nobles in Tristan.
This is The Tristain Academy of Magic. This is where Louise Franscoise Le Blanc De la Vallerie attend, She is a petite girl with Pink hair and pink eyes, she had a flat chest that she was not proud, and she also have a rather hot temper making her your typical tsundere. Louise is the youngest daughter in the house of Valleries whom an Elite house of Noble in Tristain.

She is now 17 and a Second year in the academy her grades in her academics are quite good in fact she excel on her peers in studies, but in terms of spells she fails miserably, in fact her runic name is "Zero" because of her lack of talent to complete her spells, her spells always ends up in a huge explosions they also think that she just have no Magical Talent and not worthy of being a noble.
But today it will all change as she is hoping because today is the "Springtime Familiar Summoning Ritual".

The day all second year mages will summon their Familiar Companions .She is determined to summon the most amazing familiar of all. she will show her Rival the Germanian Redheaded Harlot named Kirche Von Zerbst that she can finish the Ritual without failing, heck if she manage to summon something amazing she'll rub it in the face of her rival.
She was thinking what will her summon will be... will it be a Gryphon? a Manticore perhaps or maybe a dragon! 'Please be something amazing and special' she thought,
but her thought vanished when her Rival spoke.

"So Louise you re still holding what you said earlier?" asked the tall Redhead.

"Y-yeah I will show you Zerbst! I will summon the most amazing and powerful familiar of all!" Louise replied proudly.

"Then I'll be watching Zero!" Kirche said with a wink.

"GUH!" Louise Clenched her small fist at the redhead s comment.

"I'm gonna show that Harlot what means to be a Vallerie!" said Louise while stomping her foot on the ground.

Her anger stopped when a bald teacher stepped forward from the crowd and spoke.

"Alright, all of you listen" Professor Colbert said to his students.

Professor Jean Colbert your average everyday bald Professor he wore glasses like a common teacher but don t let his appearance deceive you. His Runic name was "The Flame Snake" and he is a retired soldier.

He served under Karin "The Heavy wind", the famous wind mage of Tristain. He has a dark past, a past that became a reason for his early retirement in the service.
None of his students knew about this and he remained silent for it. His past keeps on haunting him every day, The Screams of his victims the charred remains of humans that he set ablaze that day. All he wants now is peace and penance for his mistake and teaching in a academy full of promising young student mages.

"All of you know that today is the Springtime Familiar Summoning ritual."Colbert spoke to his students.

"and today you will summon your Familiar companion."Colbert continued.

"Now i all taught you the incantations and Binding so who wants to go first?"Colbert asked his students All the students looked at each other until someone from the crowd stepped forward.

"I-ill do it S-sir!" said the Student.

"Alright Step forward and begin the incantation" Colbert instructed the Student. The student nodded at his teacher s signal then proceeded to summon his familiar.

#################################################################################################

A few hours passed and almost all of the student have their respective Familiars, Some familiars are normal animals such as a dog, cat, mouse, bird and even some snake but some students summoned peculiar Familiars such as a Giant Floating eyeball, a Basilisk, a giant earth mole even the Germanian Redhead got a Huge Red Reptile with a Flaming Tail (no it s not a Charmander) which was a Salamander, but what tops the most is what the Gallian Tabitha summoned.

Tabitha summoned a Dragon. Its Scales are blue and its Size towers all of the familiar in the Courtyard even Its wing expand so wide that it covered almost all of them. The said Dragon seems to be a young one and it's species they are not sure if it is a Wind dragon due to its color. Louise now feels nervous, because how on Brimirs name can she top that? her confidence plummeted so low that she was wishing for any familiar now, Heck even a simple Dog or a Frog can do cause now She doesn't care all she wants is to pass the ritual so she can still continue studying at the Academy. 'Please I don t want to fail!, any familiar will be fine' she wished in her thoughts ,but her thoughts are interrupted when her Bald Teacher Spoke.

"Have all of you summoned your Familiars?"Colbert asked the students.

"No sir! Louise the Zero hasn't summoned one yet..." said a student from the crowd.

Hearing her name Louise flinched, then glared at the student that called her by her nickname.

"Miss Vallerie!"Professor Colbert called out to the pink haired mage."Please proceed with the ritual." Colbert continued.

"Y-Yes Professor!" Louise said nervously.

"What do you think she will summon?" asked a flamboyant boy in the crowd.

"Heh maybe a huge explosion or worse!" said a fat boy from the crowd.

The crowd of students began murmuring to each other about what will the Vallerie will summon. Some started to laugh and shouted some jeers and insults on her.
The Pink Haired mage heard those comments and suddenly a tick mark appeared on her head. She was about to throw tantrums at them but the bald Professor break her to it.

"Silence!"Colbert shouted at the crowd of students "This is unbecoming of a noble! all of you behave yourselves!"he trailed then signaled by raising his staff at Louise to continue the ritual.

With a nod Louise muttered in her thoughts 'Please don t fail...'.

"Here we go!"Louise took a deep breath and started the incantation.

Shadow Isle, Runeterra

Runeterra a continent in Valoran where the Shadow Isle is located. A once beautiful place called the Blessed Isle, an island gifted with treasure and beauty but after the curse that eats the whole island with Black Mist shrouding the island and all of the beauty it boasted parished and even its inhabitants are cursed and died because of the effects of the Black mist.

Creatures from nightmares replaced the islands inhabitants, The Undead freely roamed the island and search for intruders that enters the island.
Anyone gets close to the island and those who perished in the black mist that shrouded the island meets their doom. It is said that the Shadow Isle didn t really exist and the said island is haunted by spectres and malevolent spirits to became a story to scare to children if they don t behave enough.

Shadow Isle is also where Mordekaiser's Castle located he was called with nicknames such as "Lord of the Undead" the "Iron Revenant", and "The Master of Metal". Mordekaiser is Living Giant armor that wields a giant Mace that he uses to crush his enemies.

Mordekaiser was once a mortal, a brutal warlord-king that rules the East Valoran long ago before the rise of Demacia and Noxus.
All of his enemies fear him said fear they used to allied themselves with each other to end his dark reign. After the long and bloody battle he finally met his doom.
He stands in the mountain of corpse and looked at his enemies in his doom.
In his dying moments he laugh even as he succumbed to deaths door before he dies he promised his enemies that he will rise once again and take revenge on them one by one.

His body was hurled upon a immense pyre amid great celebration from his enemies. While the flames were unable to do more than blacken his armor, Mordekaiser s body was reduced to charred bones.

The fires burned for days on end, but as they finally died down and the victors moved on, a coterie of sorcerers slunk forward and sifted through the ashes, gathering up Mordekaiser s armor and bones.

They bore them away in secret, and on a moonless night they laid the skeleton upon a rune-carved slab and enacted a spell of vile, necromantic sorcery.
As their dark magicks reached a crescendo, a shadowy form appeared upon the slab. The deathly shade rose to its feet, leaving the skeleton behind.
It was a wraith formed of pure darkness, yet its eyes burned with malice. The fire-blackened pieces of armor slammed into place around the shadowy spirit, as if drawn to a powerful lodestone, and the sorcerers dropped to their knees before their risen master. They had been promised great power for their service, but had not foreseen how they were to be rewarded.

And now he is sitting in his throne staring out of nowhere and continuously sighing out of boredom, He just finished a match in the "League of Legends" of the Institute of War and it turns out an all out Victory for them. Now he has been thinking about his next schedule he Call one of his servants.

"When is my next match?"asked Mordekaiser with his deep voice.

"Sire, you have no match for today" said an undead servant in front of him.

Hearing it he sighed again as he look at his servants.

"Why am i not that popular?, like that damn Yasuo! I can best him anytime of the month!"Mordekaiser asked.

"S-Sire m-maybe because you're a little s-slow?"said the servant nervously.

"Slow? I m Slow!?" Mordekaiser shouted at his servant, well he knew he is one of the slowest Champion in the League ,Heck even that fat Drunkard Gragas can outrun him.

Seeing their Master's anger the servants gulped nervously. They knew that they don t want to piss their master.

"I beg of you!"

"Huh?"Mordekaiser heard a voice a sweet voice like a young girl. Hearing the voice he stood up.

The servants cower in fear when they saw their lord stood up knowing that they will feel his wrath.

"My Familiar that lives in this vast Universe"

"Where does that voice come from!?" The Lord of the Undead asked his servants earning some raised brows from his servants.

"We don't understand Milord." a servant asked.

Mordekaiser looks around but found out that only him and a couple of servants can be seen in his room.

"Stress is killing me..." Mordekaiser said with a sigh. His servants just sweatdropped at his comment.

"I Plead from the bottom of my heart!"

"There it goes again!"Mordekaiser said annoyed about the voice that he keeps on hearing.

The Servants in the room just look at each other at their Lord's predicament.

"Perhaps you should rest now my Lord?"The Servant asked.

"Yes... maybe I should" Mordekaiser replied.

"Answer to my Guidance!"

Before Mordekaiser move from his throne, A Green oval shaped portal appeared in front of him shocking his servants in the throne room.

"Master! is the League summoning you again?"asked one of the servant.

"No I don t think this one's from the League.."Mordekaiser replied.

"The league will most likely alert me if I have been chosen to fight for their summoners" he continued.

"Master this feels like a summoning portal." the servant said.

"Indeed...it is." Mordekaiser said eyeing the portal.

Mordekaiser feels something in the portal, it's not connected somewhere in Valoran. He felt its power calling for him the portal needs him. He looks at it curiously then the idea hit him, If this portal does not come from the League then who is summoning him?, then he remembered the Voice earlier, 'Maybe it's from that voice? whoever is summoning me must be desperate' This thought give him a chuckle, maybe this is his ticket to a new adventure.

Many idea struck him if it is not somewhere in Runeterra where? then an answer popped to his metal head "A new world" he muttered, A smile makes his way to his darkened face.

"Hue hue hue hue hue!"Mordekaiser laughs.

"M-My lord?" asked his servant nervously thinking that his master might get Violent any moment.

"I will go through the Portal!" The Undead lord declared to his servants.

"B-But Sire! What if you don t come back? What about the League? The council will be disturbed by your disappearance!"
the servant with slight worry on his Lord.

"Bah! let them be they enjoy picking that Unforgiven than giving me a spotlight!"Mordeakiser spoke with anger.

"Those fools in the Institute doesn't know power!"He paused then he answered the servant s question.

"Just tell the council that i have been summoned by another summoner!"He continued.

"What about the Castle? Sire?" The servant asked.

"Well... let Thresh, Hecarim and, Karthus take care of it at the moment" Mordekaiser answered.

"They are my trusted companions! They can guard this castle with ease from any invaders!"He continued.

"Yes Sire we shall inform them about the events" One of the servants answered.

"Very well! Farewell my Servants i shall meet my summoner!" With that the Lord of the Undead stepped inside the portal.

"Goodluck Sire!"Both servants said in unison.

In a blink the Undead Lord of Shadow Isle disappeared leaving two undead servants staring at the throne.

"Well master is gone.. so now we can relax and watch Piltover heat all night long!"One of the Servants announced with joy.

"Wonder if Officer Vi and Officer Caitlyn apprehended that notorious Jinx?" Asked one of the Servant.
