[Summary chapter Year One] + [More on Ymir & Arianna]

Volume 1 Year One Ends with this chapter.

Summary so far.

Eren is brought into the magical world for reasons unknown. He is first found, bloodied and without half his libs and an eye in an alley in the Magical Diagon Alley. There, a visiting Astoria Greengrass first notices him and calls her mother to tell the grotesque scene, essentially saving Eren in the eyes of many.

Eren is brought to the Saint Mungo's Emergency ward by soon-to-be ex-Auror Alastor Moody, who had reached the scene after reporting with Auror John Dawlish, a Healer and trainee auror.

After a week of treatment, Eren is all patched up where he is interrogated by now Ex-Auror Alastor Moody, Nymphadora Tonks, a trainee auror, and John Dawlish. Thereafter Eren is released from the Mungos after the last health check by Senior Healer Andromeda Tonks, who helps him by calling the Knight bus and giving him money for the ride.

Eren goes to Gringotts, and with an inheritance test receives the Dumbledore trust vault access, but the Goblin notifies Aberoforth Dumbledore, Lord of the House after his elder brother, Albus refused to take the Lordship.

Aberforth was surprised to say at least. With much of his House and family now beyond life, he reaches out for Eren, thinking to be Aurelius's son, his grandson, which made the most sense for an heir to be found.

Next, we find Madame Irma Pince, the librarian of Hogwarts School for Wizards and Witchcraft. The Daily Prophet tells the public that she had died due to an underlying cardiac disease but Dumbledore's sources at the DMLE said it was a murder, her heart had been pierced internally.

Dumbledore had to hire someone new for the post. He had doubted that Voldemort might be alive, and one of his subordinates had made this unfortunate event a gate for their entry into Hogwarts.

Later Eren had been hired as the librarian for Hogwarts. His first priority is found to be researching Grindelwald- but all sources directed him to the conclusion that he might be dead.

Eren had visited Hagrid again, previously they had met in Gringotts with Harry. In the hut, Eren found a Niffler, one that had been in Hagrid's hut for quite some time. Eren adopted the niffler after knowing that the creature was infamous for his stealth and love of shiny things.

In one of the Staff meetings, Dumbledore came across a strange phenomenon, where the Elder Wand... or the Deathstick was rolling towards Eren at times. He verified the event by letting it go many times. 

On Halloween, trolls snuck past the Hogwarts wards. It met Hermione who had been crying due to contact bullying. The troll had been subjugated quite easily by Yeager's crystallizing powers. Later Albus and Quirell looked after the immobilised troll, and the diamond transfiguration as they deemed it, an advanced and quite useful branch of magic.

On November 3rd Eren had been summoned by Gringotts. Before leaving Hogwarts Eren came by the cursed Mirror of Erised. Both Dumbledore and Eren confessed that they had seen a similar reflection, one including lilies, just not how the lilies were signified.

At Gringotts Heir Dumbledore was informed that his head of the house had requested a meeting. Eren complied, setting the date of Christmas Eve for the meeting.

While he was out, Eren had reached out to Bathilda Bagshot, a blood relative to Grindelwald. After a nice talk with the old lady, she was obliviated. 

Near Christmas, Eren had been asked for Nicolas Flamel by Hermione, for which he gave Hermione the reference for Albus Dumbledore's Chocolate card.

On Christmas, everyone exchanged presents. Eren had also received some, from the staff members and one pocket watch, surprisingly from a student, Hermione.

Again for Eren, coming across the mirror of Erised was fate before leaving Hogwarts for something. This time, however, he saw the mirror being gawked by a child. Harry, using his newfound invisibility cloak had dabbled into the art of curfew breaking. They discussed the dark artefact for some time before Harry was given detention.

Eren left Hogwarts on the night of Christmas Eve. Outside Florish and Blotts, he met Aberforth waiting for him, from the dawn.

They gave each other vows that neither will harm the other, and then port keyed to somewhere private.

chapters 14-15 are the base of the fic, the backstory, and how the titan-shifting powers came into existence.

It seems in the four-way duel between Aberforth's spell, Grindelwald's spell, Albus's spell and Arianna's mere existence as an Obscurial, something indescribable happened.

Arianna happened to be tossed out from the bounds of the magical dimension, into the dimension where slavery ran rampant, and Fritz's were the royalty.

She had been a slave for the royal family, before the Obscurus within her mutated, no longer held back by the laws of magic, granting permanent, hereditary powers of the titan shifting to her.

She did not want any of those, but as a girl of ten, now twelve in that world, she was forced into a life of servitude. The King, in awe of her powers, graced her with the opportunity- no one ordered her to be her concubine. 

The twelve-year-old Arianna, now Ymir Fritz was subjected to horrors beyond any world, made to fight wars for the Eldian Empire, giving birth to Maria, Rose and Sheena after five miscarriages. 

Finally when death came can greeted her body like a friend, the Obscururs within her held back her soul for themselves, cursing her for a hellish eternity of healing the bodies of titan shifters, which she continued to do for the next 2000 years, alone.

She saw how the Fritz King had her daughter eat her remains, and her grandchildren eating the remains of her daughters.

For 2000 years, she suffered, suffered eternal damnation, before Eren came.

She remembered her brothers. The memories of centuries ago were still there, she remembered Albus and Grindelwald and Aberforth. Those who could sacrifice anyone to save the world. There had been many Albus, Aberforths and Grindelwalds in the history of the eldian empire. Different names but the same noble goal.

But Eren was not them.

No Eren was not them.

He would see the world burn for that special person. For his family For his friends For anyone worth something for him.

Centuries ago she would have said it was not their fault, they did not know she would be sent here, and it was all a mistake.

But the Attack Titan holder, and later the converter of all Titans told her, it was their fault.

She was not the bad girl here. 

That they were all to blame.

He gave Ymir a cursed emotion. 

He gave Ymir love. Unconditional, Love. 

He did not see her as Ymir, the titan goddess, the bringer of destiny, war, or anything, not as Ymir Fritz of royal blood, not Ymir the titan, but just as Arianna.

Arianna, the twelve-year-old girl, out of her place, and dropped into hell.

He saw her for just her... for just Arianna. 

So she cried, all the tears for the last hundreds of years, came there. 

She cried. Arianna cried, not Ymir not anyone else.

And he gave her what she needed. 

Peace.

He took all the powers within her Obscurial. He took her curse of eternal hell and returned love for her. 

In the end, she could ask only one thing from her Father. 

Just one. Before she passed on to the next life. 

Just one.
