Earth

Earth is the homeworld of Humans and Silurians and is apparently the center of the Galaxy. Literally, if anything is going to happen at any time to do with anything, it will happen on Earth.

Geographically, Earth is diverse. It has forests, deserts, mountains and seas. It even has polar ice caps, which is apparently an achievement considering the place is so damn warm now.

Earth has been sacked and demolished around 58 times in its history. Somehow it seems to rebuild almost instantly after every war, probably using Jorgey's Composer.

Earth has many diverse countries and cities, each with their own unique take on architecture, culture, lifestyle and transport. All of them have contributed to the growth and eventual expansion of Humanity as a whole, even North Korea. Earth also has one Moon, Luna, which is loved by Humans because of its silver colour.

Earth is protected by a network of Orbital Defence Platforms, like Cairo Station. These were set up during the Human-Covenant War and remained there until the Fall of Lord Hood. After the Empire of the Hood was destroyed, Humans had to be evacuated from Earth on board the Axiom whilst a cleanup operation took place, which ended up taking 700 years.
