The life of Titan shifter

"Just a minute," Eren said, pulling his pocket watch and the niffler with it. "He is a little mischievous."

[OST Attack on Titan Season 2 - Ending | Yuugure no Tori]

They walk in a straight line, and finally, a small castle and a well are in sight.

There was a table and chairs outside beside a dry well. (Img- AOT scout old headquarters.)

"Where are we?"

"Madagascar, this place held some similarities to my home. Come sit down." The old man complied.

"Water?"

"No. I just want answers-"

"I am not your grandson or your nephew."

"Then how did you fool the goblins? How did you fool the ancient magics?" Aberforth got aggressive, not fearing Eren to harm him after his oath.

"I am still of your bloodline."

"How-?"

"Let me tell you a story." Aberforth stood up, but it was followed by a yellow lightning striking him on his wand arm turning his wand to ashes in a matter of seconds." Aberforth brought his spare wand to cast a curse but his eyes did not believe him.

Before him was Eren's body engulfed with steam, which had its limbs regrew from scratch as if there was no injury in their place.

Eren removed his bandage from his eyes, a new eye taking its place. Now he could see it- the similarities. The blue-grey eyes.

'No, it can't be possible. It is not possible. There is no possibility!' 

Eren walked slowly and took the wand from a surprised Aberforth, who was not reacting after the revelations and possibilities of such a thing.

"H-How-?" Aberforth's voice was hopeful and fearful.

*Sigh*

"About Three thousand years ago, the Fritz family established themselves as the rulers of Eldia.

The Eldian kingdom became an Empire in a thousand years and by around 1000 BC, they were one of three dominating Empires on the face of the world."

"Eldia? Fritz what are you talking about!? I just need-"

"Sit down, Aberforth." Dumbledore was taken back for his name to be used, and more so when Yeager had cut his hand. Completely unknowing of their meaning.

Aberforth complies in the face of an unknown threat, possibly blood magic, begrudgingly complying with what Yeager had to say.

"Where was I- Yes. Around 1000 BC the Eldian monarch- Fritz received the the boon of God. A power that could help him conquer it all. The world within his grasps. 

War as humans knew was over, and a new type of war fare emerged. The powers of the titan emerged. 

You see, King Fritz owned a slave, Ymir who by stories came by a tree, where something or someone gave her the gift of Titan shifting.

She grew up to be fourteen-fifteen meters tall, and her injuries healed as they were never there. No Army could resist a giant that tall. And with that Ymir spearheaded hundreds of wars, securing the Eldina domination.

In return for such boon, King Fritz graced Ymir with the golden apple- to be her concubine her broodmare." Eren recited the story with no change in expression while Aberforth was disgusted by the story.

"Ymir complied, as a slave and nothing more, she complied. and every day the King would fuck her, from the age of twelve to the rest of her life. You see, he wanted more of her, more of Titans. About five miscarriages later, her womb mutilated every time, and she gave birth to a child, Maria, then Rose and last child Sheena. Any more of her children were stillborn.

Finally, Ymir was free after thirteen years of her servitude. Death greeted her body like a friend and she died while protecting the King. A noble death.

Upon her death, the Eldian empire lost its weapon of domination. And the children of Ymir did not show any hint of titan powers the King thought of a method." Aberforth was listening quietly making sense of the story.

"My daughters. Give birth and multiply. The blood of Ymir must not perish. If you die, my daughters, have my grandchildren eat your spines. If my grandchildren die, pass their spines from child to child. Even after I die... my Eldians will rule the great lands of this world with their enormity. And my Titans shall reign forever and ever."

He was alarmed.

"King Fritz forced- no, asked her daughters to eat the dead Ymir, and so they gained the powers of Titan shifting. From them, the powers of the Nine Titans emerged. The Eldina Empire ruled the world as they knew it for 17-1800 years.

In about the year C. 750 Karl Fritz, the 145th monarch of the Fritz family, inherits the Founding Titan and succeeds his predecessor as the monarch of Eldia. Ashamed of Eldia's history of genocide he conspires and gathers most of the Fritz royal family to Paradis Island, Eldia's last remaining undisputed territory. 

This incited war among the others who had titans with them, the remnants of Eldia. Over the course of the war, the Marleyans took advantage and succeeded in gaining the power of six more of the Nine Titans possessed by Eldia: the Colossus Titan, the Armored Titan, the Female Titan, the Beast Titan, the Cart Titan, and the Jaw Titan.

Using the seven Titans, Marley gradually gains control of the continent. King Fritz uses the Founding Titan to create and order countless Colossus Titans to form the three concentric Walls—Maria, Rose, and Sheena—to protect the remnants of Eldia.

In order to stop the war, King Fritz sends a false message to the people of Marley, demanding that the surviving Eldians must be left alone or the Colossus Titans will "flatten the entire Earth" quite literally.

I was born on March 30th, 835 C to Carla and Grisha Yeager, the Attack titan at that time."

"You see, the attack titan has another power besides the shifting, Like other Titans. Its users could meet its previous users." Aberforth flinched at the possibility.

"And I met the original, the founder of the Titans. The Devil of Earth, the God of Eldians, the founding titan. I expected to see an all-powerful being."

...

"But what I met was just a girl. Cursed for suffering till the end of time. Cursed with powers beyond her, memories of bleeding heart, thoughts crueller than truth, wounds painful than love.

She was just a girl. Not of that world. A cursed existence. 

She was just a twelve-year-old girl there. Not the First titan, the protector God of Eldians the Devil of the world.

She was just a girl there. Not Ymir Fritz

Just Arianna."
