Prologue: Let's start at the very beginning.
It was 1945.
Albus Dumbledore, one of the greatest wizards to ever walk the earth, had decided to embark on a noble crusade of righteousness against one Aurellius Dumbledore, and one Gellert Grindelwald, myself. He was of the opinion that my own plans to interfere in Muggle affairs such as the second Great war, eventually reveal wizardkind to the world, and establish a new order that would put wizards with talent and ingenuity over those who did not, and thousands of Muggle slaves to wait on their master's every need or desire.
I was personally of the opinion that he was standing in the way of progress, and caring for a race of beings that were unable to use magic, had and would likely continue to be hostile to us based on history, and had a very narrow view of things. "Good." That's what he claimed to be crusading for. A concept that got in the way of actions one could use to both gain plenty of power, and advance themselves through life with a much more casual ease than those who adhered to concepts like "Good" and "Evil."
Personally, I couldn't believe Dumbledore actually adhered to such things. At least, I mused with a reluctant sigh about the man I loved's actions, his brother didn't carry the same delusions. Ah yes,
Credence. When I had originally met the young man, his identity had been unknown to me. My gift of clairvoyance had shown me that an incredibly powerful Obscurus would be able to kill Albus and despite previous contingencies keeping him from acting against me, one could never be too careful.
I had mistook his younger sister to be the Obscurus due to no recorded ones surviving to be his age, and cast him aside after assuming him to be useless.
His response to my foolishness at the time nearly destroyed New York City, and it had taken me a long amount of time to string him along and regain his trust. But now he was here, at my side. Aurellius Dumbledore, a person of mass destruction and enough power to kill Dumbledore.
It was regrettable that he must die, but his opposition was more than simple annoyance. Unlike several of the others in my way, Dumbledore actually had both the honed strength and knowledge to bring my work to an end.
As Dumbledore and his pawns approached Nuremgard Castle, I sighed and made sure everything was in order. The dis-apparition charms were in place preventing anyone from apparating in for miles, similar to Hogwarts's own security measures. Abernathy had been tasked with erecting as many barricades as possible to slow their advance, Gunnar was marshalling as many of my soldiers as he could to both keep Albus's forces from entering to bother me, and to make the chokepoints Abernathy was setting up into a meat grinder, akin to the slaughterhouses muggles used for cattle. Queenie would halt Newt and Tina and their muggle companion, and Vinda would do her part in making sure that we weren't disturbed.
Dumbledore himself made it through Abernathy's barriers within the first fifteen minutes of the skirmish. Newt and Tina made it through within thirty four. Somewhat impressive on their parts, I noted as the slaughter began to take shape in the courtyard. Even the muggle was doing well, even if following the path his friends blazed before him with little effort on his part besides a few blows and assaults.
"Cave Inimicum." I muttered, as the room I was in began to mold itself in response to the Elder Wand, defenses springing up, traps being set, and nothing that would do anything more than slow his advance. Into the room behind me I went, Aurellius waiting.
Dumbledore arrived as quickly as he could, the sounds of several of my subordinates panicking informing me of his approach.
"Albus." I spoke, as he slowly made his way through the defenses, blocking my first volley of spells with ease. "I'm so glad you've arrived. I'm impressed you managed to gather so many supporters, given your lack of collaboration with the ministry. Tell me, just how many of them are teachers?"
"A few." He responded with a bit of coyness as he made it through the final barricade, nodding to both myself and Aurellius.
"I don't believe you and your brother have formally met each other. Albus, Aurellius. Aurellius, Albus."
"Charmed." Aurellius replied with a stonelike expression, with only the scowl and minimal movements keeping him in contrast with the sculptures adorning the...increasingly damaged castle. After we were done here, I was going to need to renovate Nuremgard.
For a brief moment, all of us remained silent. Albus held his serene expression, and the two of us smiled at each other while Aurellius simply glared at Albus.
It was he who cast the first spell.

"Immobilus!"
Jacob froze in place as Queenie's spell hit. Unable to move, unable to continue getting in their way, unable to keep reminding her of why she had switched sides, unable t-
"Stupefy!"
Be a distraction. She grimaced as she turned to block Tina's own spell, and then dodged Newt's own by millimeters.
They were a pair, the two of them. Acting in tandem, complimenting each other's skills, and keeping her on the ropes. She was beginning to think that Grindelwald didn't know what he was doing, telling her to keep the three occupied in this specific spot, while he and Aurellius fought Dumbledore. Dumbledore! She was beginning to think less on winning this encounter and more on getting through it.
That was when Vinda dropped the building on them.
Herself included.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Fire spread from the Elder Wand to be doused by water coming from Albus's own.
Bursts of energy tore through parts of the wall and floor where he was- had been standing as he moved to counter Aurellius's powerful but clumsy attack with his own weaker yet more finessed bolts of lightning.
The fight moved up Nurengard's ornate tower, with each blow being a step and each step becoming a blow. Bits and pieces of stone, wood, and glass tore off from the building and flew at Albus, only to be batted aside or collapse into sand. More bursts of energy from Aurellius, as the tower actually shook from the blows. I gave a brief look to him of disapproval at the large amount of damage he was doing, before a blast of pure light itself nearly tore through my shoulder.
Dumbledore kept pushing. Finally, there were no more stairs to move up, and we were on the top of the tower, where we could see every single bit of the battle. Wizards marched into a increasingly growing meat grinder, trained beasts tore through my soldiers and- Queenie was in position.
"Vinda." I hissed once as I cast a single nonverbal spell. "Do it n-"
A single bolt of light tore through my leg, as I fell and gave a shriek.
For a brief moment, Dumbledore's attention tore itself from Aurellius to me, and then to the scene below as the tower began to shake.
Newt Scamander, Tina Goldstein, Queenie Goldstein, and the Muggle vanished under a lot of rubble, as the tower itself began to move, causing me to question if I had miscalculated in a single moment of panic.
Thankfully however, it stopped, and I turned my attention to- A single shadowy tendril poking out of Albus's chest like a large spear of some sort, followed by more as Aurellius tore through him like a beast of prey. A single teardrop appeared in my eye for a moment, only to be concealed by a look of disgust at what little was left of one of the greatest wizards to ever live.
"Episkey." I snarled, as the elder wand did its best to patch up my leg's damage, and I got to my feet with a limp, nodding to Aurellius.
"Bring his body."

A/N: Hello all. As an avid fan of
@YeahOkayCool 's "Memoirs of Darth Plagieus" fan work, and a fan of Harry Potter, I pondered making a fic where Grindelwald defeats Dumbledore and begins working on his own big picture schemes, all the way up to the 90s with Harry Potter and friends in a English Wizarding World ruled by him.
Figure I'll see how far I can take this.
Hope you all enjoy!
