The Dustlands change forever at the end of season 1. Kettlemine becoming a source of functionally infinite fresh water upends the region’s economy and power structures, and that’s just the start.
As the Dustcaps make their way through the world, they’ll discover more examples of White Barrow’s sins, and their miracles. They’ll encounter new settlements and survivors who’ve hidden for decades. They’ll encounter new forms of life that have adapted to their world better than they ever could and old forms of life that cling tenaciously to a past that burned before the Dustcaps were born.
But most of all, the Dustcaps will find themselves at the crest of a wave of change that will change their world forever and do so for the better.
