"Wait a minute, what do you mean when you say "One of the most deadly wars in history?" Ozpin asked the helmet wearing man.
"Well, you know how you guys had "The Great War?"
"Of course, it's one of the first things I learnt about as a General, why do you ask?" Ironwood answered.
"Imagine that, but with more death and entire cities being destroyed in minutes,"
The theatre would pause in terror at this, even those in Salem's faction sans Tyrian would shiver at this "What could be more deadly than the Great War?" they'd all think to themselves.

Ruby would be the first to speak up "W-what do you mean by entire cities being destroyed?" She'd ask, hoping the man was joking.
"Exactly what you think I mean, cities would be bombed, populations would be killed, it was terrible," Slays would answer, making Ruby sit in spooked silence.
"By the way, before we get into this, the people from the reality that this takes place in are all gonna be replaced by you lot. So while Ruby in here might be a nice girl, she might an evil, racist dictator hellbent on killing populations based on her own prejudices, Salem might be a dead revolutionary instead of an evil god thingy, etc, etc,"

The cast would sit in confusion, but would eventually nod, getting what the man was trying to say.
Salem would be confused at the man's statement, while Ruby would shiver in fear at the thought of her doing that, Yang would put a comforting hand on her shoulder.
"Don't worry, Sis, while you might be evil in there," She'd point to the Screen. "You'll always be good in here," She'd point to Ruby's heart.
"T-thanks, Yang,"
"No worries, Sis!"

"By the way, considering you're all about to see some mega fucked shit, I'm gonna bring someone back. Skiddadle Skiday, stop being dead Magnet Waifu," Slays said.

Suddenly Pyrrha would just pop back into existence, making the entire theatre stare in utter shock.
"P-Pyrrha!" Jaune would say, running towards the girl.
"Jaune! It's you!" Pyrrha would declare.
"Jaune could you tell her what's going on?" Slays would ask.
"O-okay," Jaune would say, explaining what they were about to watch, making Pyrrha look as scared as the rest of the theatre.

"Before we start, you should also learn how this world works, instead of four kingdoms, there's hundreds of different countries in my world most of them have different languages, currencies, leaders etc,"
The theatre would be astonished at this, that amount of languages and nations both scared and intrigued them.

Jerry the Monkey would start the film and the theatre would prepare to see one of the most important events in Slays' world's history.

World War II in 39 minutes

The audience would shiver at the fact that this was the second "World War".

There'd be trumpets playing while a scene of horses and soldiers walking down a street, which would then cut to a man in a German military uniform, complete with a helmet with that spike on it saluting at the camera

"Nice helmet," Coco commented.
"I know right? It's called a Picklehaube, I believe, traditional German thing,"

The black bar at the bottom of the screen would say "Nov 1918 - End of World War I Germany signs the treaty of Versailles (1919).".

"What's this "Treaty of Versailles?" A curious Salem asked.
"It was the German terms of surrender for World War I, they had to: Shrink their Military down, demilitarize a part of their own country and a pay a huge amount of money they didn't have," Slays would answer.
"So, once they won they decided to weaken this "Germany", how cruel," Salem would think to herself.

The bottom of the screen would say "Germany's economic sanctions: 132 billion marks," While a woman could be heard singing in German in the background
