On the year of 1962, a strange event had occurred in the lands of the former Soviet Union. This tale began when squadrons of German bombers were tasked to continue their duties of exterminating the Russian people and the remains of their civilization. It was supposed to be a normal bombing run... until it wasn't. Pilots started to report a geographical error in the Southern Urals, where lakes had replaced what was supposed to be mountains.
For several weeks, the Oberkommando der Wehrmacht viewed the initial reports with skepticism. Then they ignored it and moved on with their duties as they had other priorities than shattering the destruction of what they saw as subhumans. Despite their unwillingness to accept the reality that a piece of land had simply disappeared, the commanders of the Luftwaffe matched the reports with other squadrons. Evidence of this disappearance couldn't be ignored as they proceeded to inform the higher echelons of the Nazi government.
It was the most bizarre event to have happened in history and it piqued the interest of the Third Reich. Yet, the distance between the disappeared land and the frontiers of the German settlements was too much for them to care. After all, the important government officials of the Reich were preparing to carve up the remains of Hitler's ambitions as he lay on his deathbed. Some going so far as to destroy their fellow Germans for power.
At best, the disappearance of the Russian region had remained a footnote compared to the priorities of what the Germans had for the future. In the eyes of the Nazi regime, if it caused a possible loss of life for the Russian people the fewer subhumans they would have to deal with in the future of conquering the eastern front.
In hindsight, the Germans should have taken the disappearance of four important individuals seriously. Although there were those who would miss the Anarchist-Communes of the Orenburg Council or the valiant peacekeepers of the Ural League, it also removed the threats of the Dirlewanger's Brigade and the mysterious soldiers of the 22nd Motor Rifle Division of the NKVD who occupied the infamous Black Mountain.
One could say it was a blessing or a curse, but what can be certain in this tale is that these four minor groups would bring the future of the Motherland when they returned. Until they came back to their world, these people of the Southern Urals would find themselves in the world, unlike their own - Remnant.
When morning came, an eerie silence had disturbed many of the people in the village. For the first time since the fall of the Soviet Union, the Luftwaffe bombings stopped. There were no recent bomb craters or new casualties to those that snuck out in the middle of the night. People thought of this as a strange ruse by the Germans, but things didn't stop there. Trucks full of soldiers from the Ural League were passing through in their worn-down Red Army uniforms. Apparently, they were passing by to see whether their reports was the same as other villages.
One of the soldiers - a young man - stepped down from the truck to see children playing in the streets while many civilians talked amongst each other about the lack of bombs in their village. Underneath his right arm was an old sub-machine gun that had seen battle during the era of the Great Patriotic War. He looked to his left to find a fellow comrade from his platoon finish a conversation with a civilian and then he approached him. "Oleg, is there any news on the radios why the Nazis stopped bombing us?"
The soldier, who was far older than he was, had begun to shake his head. "Nyet, there is nothing except static. Alexei, how about you report this to the comrade-captain? He might get word to the rest of the company."
"I'll go do that. Hopefully, this is the last time we'll ever sleep with bombers over our heads."
The world of Remnant was surprised by the air of change that had occurred. Shipping lanes and trading airships were spreading rumors that they were discovered new land. Of course, those who made these claims were met with skepticism and ridicule by government authorities. Yet, they continued to plague the news media as some people took the chance to see for themselves. To quell these rumors, an Atlesian patrol fleet had been tasked to locate the new landmass.
They had found it.
A newly discovered land had been found and General Ironwood took the initial report with great interest. Scouts reported that the land was far different than the other continents as the Grimm were no longer sighted throughout the land. He took the information in with caution, but these developments were enough for him to pull his scroll out of his pockets and call a friend. "Ozpin, I got something that may concern you."
Author's Note: Originally, I had no intentions of making a HOI4/RWBY crossover again, but a plotbunny occurred in my head with an old idea.
For those who don't have a slight clue what I'm crossing with, there is this mod called The New Order: Last Days of Europe. To summarize the alternate timeline, the Third Reich and the Japanese Empire have conquered their territories and broke the Soviet Union into various factions. The rest of the free world is basically sitting in the United States. However, they kinda don't have much impact in this story until I decide otherwise.
With the Southern Urals transitioned into Remnant, they sit in the middle of the seas between Atlas, Mistral, and Vacuo - interrupting trade lanes with their arrival.
