Panacea

History
Climate change has brought extremes but more importantly because of environmental refugees there was a war started that engulfed the world.
Domes called Shields were placed over the cities to have safe places to live. This brought the fighting to an end in most places as the Shield Makers insisted that a place be safe and stable before they would allow the dome to be made.
Panacea was named another city but when they started over they gave it a new name. It is most like on the east coast of America but I'm tempted to place it further down in Mexico as I have made it generic enough.
