1940, two years after a brutal civil war that saw the return of Kaiser Wilhelm II, the revived German Empire has become the most dominant military, economic and technological power in most of Europe, having reformed the Central Powers and conjured major technological advancements that would change the world forever. But just as a second world war was approaching, an enormous magical gate has opened up in Berlin and what poured out was an army of armor-clad warriors and mythical monsters from another dimension that attacked the city, with a man who was leading them naming it the "New Arthurian Province." The attack was repelled, but the gateway, dubbed the "Gate of Dimensions," remained in Berlin. The Kaiser, fearful of future attacks, mustered a massive army of tanks, infantry, armored dogs, and supersoldiers to investigate the other side of the gateway. What they came across is a world ripe with magic, an abundance of natural resources and otherworldly forces that exist within.
