Earth

Earth was the birthplace and homeworld of humanity. It is 5,012 light years from Astra. Known continents and countries include Africa, Russia, the United States, China, India, and Japan.

According to the students of Caird High School, Earth was mostly destroyed by World War III as a result of the Cuban Missile Crisis going nuclear. A new world government soon followed afterwards.

In reality in 2049, an asteroid was discovered to be on a collision course with Earth. With only 8 years until the asteroid struck and wiped out all life on Earth, humanity made plans to evacuate the entire planet to a new world.

However, when the news broke out, many old conflicts were renewed as nations fought bloody wars with each other to get access to the new world that humanity had discovered, exacerbated by the new wormhole technology that had been discovered. After the death of billions, the survivors evacuated to the new world.

Earth was then destroyed by the asteroid with debris clouding the atmosphere, and the debris prevented the sun from reaching Earth, causing a massive new ice age.
