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

Just one

Arianna wanted Eren to hate her, for destroying this perfectly normal world.

For killing people in ways unimaginable to others.

For cursing this world.

"The world was cursed long before you came. It was not your fault. It was never your fault."

And she cried, leaving this world into the world of unliving, finally at peace.

For Eren, watching the girl suffering was enough.

How much did they have to suffer?

From the dawn of the Eldian Empire, how many died just because some children had attacked each other with spells? 

It was never her fault.

Eren did not blame the children of the other side either.

But Arianna, or Ymir was not forgiving. Maybe she was in the beginning, thinking she could do everything, a new start in this world.

But now now. She had but one wish.

[summary continued]

The next day after meeting with Aberforth, Eren comes into the Grand Christmas week feast, a tradition at Hogwarts from when it first started.

There Dumbledore informs that he will be organising the bi-monthly staff meeting a day before the norm, as he had an emergency Wizengamot summon, by Amelia Bones regarding something secret.

The same night, Harry and Draco were given detention in the forbidden forest, due to being out of bounds the day before.

There they follow the Unicorn blood trail, and Draco becomes pale white. 

He then explains that a Unicorn is the purest a living being could be, and killing it was a taboo by magic itself. Drinking the blood of a slayed Unicorn is something even the darkest wizards refrained from.

A cloaked figure casts the killing curse towards them, which Malfoy saves by pushing into opposite sides, ultimately saved by the arrival of centaurs.

The events once followed at the end of the term, were being followed in December end. The Golden Trio reached out to Professor McGonagall, with information about the philosopher's stone and how it would be stolen that night.

Meeting a response they did not expect, Hermione suggested going to Professor Yeager, as Eren had been supportive of all the students in the school, counselling them on matters, personal and public ones.

Eren responds like Minerva, but to their relief, he informs them that he will check the security arrangements himself.

The Golden trio, trusting they were followed him into the third-floor restricted area, under the invisibility cloak, which Eren promptly ignored.

In front of the Mirror of Erised, they (Eren and Harry) find Quirinus Quirell. Where he reveals he has the Dark Lord present in the room.

Ereni petrifies Harry, dueling Voldemort, now possessing Quirell wholely. The unforgivable were cast like they were stunners. After a brief duelling, Voldemort, pushes Eren down, using the Cursiatis curse on him for a long period.

He then tries to find Harry but finds himself stuck on the ground by means of the diamond transfiguration Quirinus had seen, as Yeager's word.

Surprisingly the torture curse with unimaginable pain, did not have the desired effect on Yeager.

The two again aim their wand at the other and push a wave of the killing curse which meets the others' in the middle. 

The two curse wrestle for domination, where the Dark Lord uses the life force to fuel the spell, his and Quirinus's. 

His spell enlarges and gains more momentum, nearly reaching Eren's wand and hitting him, before Harry pushes him aside, burning the flying wraith of the Dark Lord to Oblivion, if not the minimum part of it flies away.

Just in the nick of time, the staff approaches, with Dumbledore and Severus witnessing the last moments of the Dark Lord's majority of the wraith.

Minerva aims her wand at Eren, but the situation is relieved by Albus' and Harry's words.

The matter of Quirell was made public, establishing himself as a dark wizard and you know who's sympathizer. Eren gains some fame for defeating and protecting children.

The next day Dumbledore talks to Harry and Eren in the infirmary, telling Hary how his mother's protection of Love defeated the Dark Lord twice.

To Eren, he offers to be one of the Order of Phoenix, an organisation which actively participated in the first wizarding war, now much needed after the fact that you know who was alive was established. 

In the next Great Hall's grand feast, Dumbledore announces the promotion of Eren from Librarian to full-time Defence against the dark arts professor.

Just then Amelia Bones, the head of the DMLE arrives and places Eren under arrest for murdering Lord Aberforth Dumbledore, Lord of the Noble House of Dumbledore.

His trial is organised the next day itself. Surprisingly, Eren is only charged with the murder of Aberforth Dumbledore, and not Irma Pince and Quirinus Quirell as the daily prophet had reported a day prior.

The trial becomes an international incident because the victim happens to be one of Dumbledore's family, the family of Supreme Mugwumpt of ICW, Chief Warlock of the Wizengamot and many more titles.

Trial Chapter 22-23-24 

In the end, it is established under veritaserum that Eren Carla Yeager, or truthfully Eren Grisha Yeager-Dumbledore-Fritz is the new Lord Dumbledore by blood and will of Aberforth Dumbledore, who had actually killed himself, due to reasons unknown.

Suicide happens to be one of the worst taboos in the magical world because it means to forfeit magic's greatest gift, life.

The Daily Prophet reports the situation and most of its major points, including Albus Dumbledore's leave from the office of Chief Warlock of Wizengamort, Supreme Mugwump of the International Confederation of Wizards and the headmaster of Hogwarts School for Witchcraft and Wizardry, for a period to the beginning of the next term.

The House Cup is won by Ravenclaw, but the Weasley twins somehow make changes to make Azkaban win the House Cup.

The Year One Ends here.
