Just being realistic. If the Third Reich was victorious, some ugly things would immediately follow, and over a period of thousands of years, what do you think would happen? So were talking about a setting that begins with a victorious Third Reich, seems like a logical beginning for Mirror Universe, that is the good buys did not win, and the bad guys are evil and they will do evil things. So throw some player characters into this Universe at about the same time as Classic Traveller but in this parallel timeline, what would you expect they would find? It could be a result of a misjump for instance. At first they think they are where they are supposed to be, all the stars are in the right place, but when they land on a planet or even when they use their radio to contact authorities, they immediately notice some differences. The Language of this imperium is derived from German rather than English for example, some computers can make the translation, but is is annoying, they land, and who do you suppose would meet them at the Starport?
