Atlantropa

The stories of Atlantropa take place in an alternate history, where the Atlantropa Project actually took place.   Atlantropa, also referred to as Panropa, was a gigantic engineering and colonisation idea devised by the German architect Herman Sörgel in the 1920s and promoted by him until his death in 1952. Its central feature was a hydroelectric dam to be built across the Strait of Gibraltar, which would have provided enormous amounts of hydroelectricity[4] and would have led to the lowering of the surface of the Mediterranean Sea by up to 200 metres (660 ft), opening up large new lands for settlement, for example in the Adriatic Sea. The project proposed four additional major dams as well :

Across the Dardanelles to hold back the Black Sea

Between Sicily and Tunisia to provide a roadway and further lower the inner Mediterranean

On the Congo River below its Kwah River tributary to refill the Mega-Chad basin around Lake Chad providing fresh water to irrigate the Sahara and creating a shipping lane to the interior of Africa

Suez Canal extension and locks to maintain Red Sea connection

Sörgel saw his scheme, projected to take over a century, as a peaceful European-wide alternative to the Lebensraum concepts that later became one of the stated reasons for Nazi Germany's conquest of new territories. Atlantropa would provide land and food, employment, electric power, and most of all, a new vision for Europe and neighbouring Africa. The Atlantropa movement, through its several decades, was characterised by four constants :

Pacifism, in its promises of using technology in a peaceful way;

Pan-European sentiment, seeing the project as a way to unite a war-torn Europe;

Eurocentric attitudes to Africa (which was to become united with Europe into "Atlantropa" or Eurafrica), and

Neo-colonial geopolitics, which saw the world divided into three blocs—America, Asia, and Atlantropa.

WW2 never happened, so the Nazi ideology never ceased to exist and grounds itself in the new society. The settlers of this newly created continnent founded a city, Monopolis. By the time the sea completely evaporated, the illusion was gone. It was not a fertile land abundant in opportnunities, but a salt canyon, arid and dry, with extreme temperatures, devoid of life. The sea was the only thing stopping the Sahara destert from spreading up North. Without it, it would sweep over Europe, and the placed spaired from destertification, those on the Pacific shore, would get flooded by the 10 meter rise of the ocean, and ravaged by the ever increasing natural disasters. The only bastion left for Europe and Africa would be the only place built in prevision of the situation. The place built by those who witnessed the changes arround them, the corrosion of the world, and who were all to familiar with why it was happennig. Monopolis would become the last bastion, the last city, standed on a sea of salt. To survive temperatures of up to 80 degres celcuis, they had to dig. And so a vast underground city was built, constantly expanding to accomodate for the flood of climatic refugees.
