WELCOME TO THE ID-IVERSE
It was called The World War.
But others call it the awakening of something greater. In the summer of 1918, towards the end of the First World War, an alien race from another dimension arrive to Earth's European region. The US, who had been spying on Germany and the Axis powers via radio feeds since 1913. Were one of the first, other than the European Powers to discover this alien threat. The Great War continued from 1914-1927 when the last alien ship retreated. Now Europe is a wasteland, Alien technology has lead to numerous new discoveries and the history timeline is forever altered to a bizarre new world.
