## General Information

**Earth** is the third planet from the Sun. About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also by lakes, rivers and other fresh water, which together constitute the hydrosphere. Much of Earth's polar regions are covered in ice. Earth's outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates Earth's magnetic field, and a convecting mantle that drives plate tectonics.

According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, life appeared in the oceans and began to affect Earth's atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties and geological history have allowed life to evolve and thrive. In the history of life on Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinctions. Over 99% of all species that ever lived on Earth are extinct. Almost 8 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans increasingly impact Earth's hydrology, atmospheric processes and other life.

Earth's atmosphere consists mostly of nitrogen and oxygen. Tropical regions receive more energy from the Sun than polar regions, which is redistributed by atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature. A region's climate is not only determined by latitude, but also by its proximity to moderating oceans and height among other factors. Extreme weather, such as tropical cyclones and heat waves, occurs in most areas and has a large impact on life.

Earth's gravity interacts with other objects in space, especially the Sun and the Moon, which is Earth's only natural satellite. Earth orbits around the Sun in about 365.25 days. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Solar System and the largest and most massive of the four rocky planets.

## History of Earth

*This is a copy of the United Galactic Nations History section located here.*

Earth is mostly know for the races and nations that came from it. Specifically speaking, The High Republic, United Galactic Nations, and Magana. Most of Earth's general history is the same. However, Earth was a colony of The Mercian Empire.

During the late 2050's, many of **earth**'s original nations began to collapse due to economic and political hardships. As each nation fell they began to form super nations/alliances there were two major ones formed, The Union of the American Continents (UAC) and The Union of Asia-Africa-Europe (UAAE). After the two major world powers formed, the United Nations kept its original purpose as a place where world powers could talk and act peacefully. These two, albeit newfound, superpowers could not and would not act peacefully and a civil war began (See War of Unity). The UAAE could not match the military might of the UAC, mostly due to the UAC being composed of the former United States military. The war was fairly short and only lasted a single year, but it's impact lasted decades. After the war, the UAC, alongside the remnants of the UAAE, decided to merge into the UN forming the United Nations of Earth. The founding of the UNE marked a new era on Earth, named the Era of Unity.

### Era of Unity

The Era of Unity, was marked with rapid expansion both political and economic, colonization, and peace. The UNE expanded with colonies on Mars and Venus and the building of the Magna Lux Station in the Kuiper Belt. Alongside this newfound expansion came new enemies and alliances, the UNE made enemies out of The High Republic and friends out of the The High Empire, resulting in the UNE taking part within The Galactic Civil War. Due to the UNE's involvement within the The Galactic Civil War the UNE had a minor hand in the Tragedy of the Triskelion System. The Era of Unity was a semi-golden age of Earth and the ending of which was marked with the blood of innocents marked by the hatred fueled by division. The Era of Unity ended with the terrorist attacks by the Kera'Menage on London, Shanghai, and Moscow.

### A Star has Fallen and Reconstruction

*The events of this portion of the history of Earth is told within the story A Fallen Star.*

After the bombings two new nations were made or reformed in the aftermath, The Republic of Texas and The Martian Military Republic. After the events of the Lunar Siege and the systematic extermination of the Kera'Menage, the inhabitants of the Sol System learned an important lesson, a nation cannot stand if it is not willing to evolve to the new order of things. With this lesson in mind the United Nations of Earth became the United Galactic Nations (UGN) and gave every member of the former Earthen colonies complete autonomy and invited them to join this new union. The promise of complete autonomy over their own worlds cause the Republic of Texas and The Martian Military Republic to rejoin the UGN. With the foundation of the UGN, the capital of the now defunct UNE was moved to New London as it had been reconstructed. Alongside the reformation The High Republic and The High Empire had settled its grievances with one another and sent requests to become allies with the UGN.

### Era of Alliances and Empires/Second Era of Unity

The Era of Alliances and Empires, also known as the Second Era of Unity, is the simultaneous golden age of the UGN, High Republic, and High Empire. This era was marked with the reentry of The Mercian Empire to the galactic political stage and the return of the benefits and advancements of the First Era of Unity. The Era of Alliances and Empires was marked with another major advancement, the common theme of heroes and the return of hero schools. This return marked beginning of the current era... The Age of Heroes...
