I wanted to explore the places of this world for a while now, here's a start for the North Shattered Islands. These islands are interconnected with a railway network. Nature and green is very present there, the climate is similar to current Europe.
A lot of people kept the structures of old Europe for architectures, but this idea of diving human habitats into nature is pretty common now. Most people are scared of another disaster and do their best to respect it, more than ever. They also use some lights with organic shapes because they believe in their protection capacities. You can see a lot of them where humans have the habits to walk or stay
