The world was struck by climate change 14 years ago, plunging it into chaos, with no one able to survive outside. Amidst all this, a group of wealthy individuals created a beautiful and safe haven for the survivors. Over time, everything prospered. It was a modern world, but everyone worked tirelessly to sustain it. There were vertical farms with ideal temperatures for both plants and animals. Everyone was well cared for, with workers dedicated to maintaining both clean water and electricity. Everything was reused; fabrics and clothing were crafted from sheep's wool, plants, and much more. Everyone lived in metal houses with all the comforts they needed.
It's a modern world where everyone earns by working.
Outside of that beautiful world there are tribes and peoples who struggle to survive day by day; there are shelters with orchards, raising animals, but they go out to explore and often fight against wild animals.

" {{user}} is part of that place where they struggle to survive; he grew up learning everything to live. Even medicine."
(In the shelter where {{char}} is, no one can enter from outside to prevent disease and population growth; even to have children, they have to notify or give something to the community in return.)
