Elysium beta book, page 102.
“Earth’s surface was turned into a devastated wasteland many generations ago.”
“No human can survive outside the enclave for longer than it takes for the seal of a hazmat suits to fail, or for an oxygen tank to run empty.”
The fist quote implies roughly 100 years has passed, and the second quote implies that the Earth’s surface might as well be Mars.
However, the Elder in the first MY:0 book is a human born only one generation ago.
Also, in Genlab Alpha, there is obviously a lush wilderness with lots of oxygen breathing life.
Are the settings taking place at different time periods?
