Terra

Terra, also known as Earth, is the main setting of Project Lazarus. After WWIII most biomass was lost, and earth became a desert wasteland. The antimatter bombs used in WWIII destroyed most of the ozone layer, and blasted a large amount of the atmosphere into space. Due to this, and the accumulation of carbon dioxide, Earth became a desert planet. The antimatter explosions slowed Earth's spin so that one day is around 32 hours. After the war, Earth was so damaged that most of its inhabitants stopped calling it earth and began calling it Terra.
