It was a nice, good ol' sunny day in Vale. People were doing whatever they had to do, children were playing, grimm were killing etc.
Suddenly, a fucking wormhole opened. "Die Wacht am Rhein" Started blaring so hard that the area surrounding the wormhole disintegrated and it could be heard from Mistral.
Thousands of landkreuzers with vril energy cannons rolled out from the ashes, shooting everything in sight. Billions (literally) of men started running around everywhere, killing people while shouting "HEIL HITLER!".
And then millions of flying disks dropped shit tons of bombs with multi-megaton thermonuclear warheads everywhere, rendering the region uninhabitable.
The Wehrmacht proceeded to do this with every other city, defeating Remnant.
Now, every single Ubermench was happily living under the guiding hand of Eternal Fuhrer Adolf Hitler.
Of course, all of the people considered to be Bolshevik sympathizers died a death.
THE END
