Earth

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System.

History

According to SRPA researchers, about 60 million years ago Earth was occupied by an alien race known as the Chimera, or more specifically their progenitors the Pure Chimera. The planet became the site of a massive battle between the Pure Chimera and an unknown race that devastated Earth - the Chicxulub crater was created from the fallout - and forced the Chimera to evacuate from the planet. Before their departure, the Chimera constructed a network of towers across the planet and buried them for eons.

Millions of years later, humanity evolved and dominated the planet. During the early 20th century, Earth's nations engaged in the Great War that lasted from 1914 to 1918. In the aftermath, the victors of the war carefully crafted a three decade era of peace and prosperity. This peacetime would later be broken by the Chimeran War.

Beginning in 1908, the Chimera returned to Earth by deploying a virus-infused meteor that impacted in Siberia. Within two decades the virus infected the native humans and mutated them into Chimera. The Russian authorities engaged in a losing war against the Chimera and failed to inform the other humans about the alien threat. By 1949, Russia had fallen to the Chimera and millions of humans were converted. In December 1949, the Chimera expanded their forces out of Russia and invaded Europe and Asia. It was not until the Battle of London in 1951 that the Chimera suffered their first major defeat which by a month later they lost control of Western Europe.

Despite the Chimera's defeat in Europe, the Chimera fell under the control of Daedalus and aggressively expanded their conquests across the planet. By May 1953, the Chimera succeeded in overrunning Africa, South America and North America in order to excavate the dormant Chimeran towers. Daedalus was killed by the Sentinel and hero Nathan Hale, but he achieved his goal to activate the tower network to form a wormhole to the Pure Chimera's home planet.

By 1957 the Chimera had won the Chimeran War and rendered over 90% of the human population either dead or converted. The Chimera proceeded to use the tower network to cool down Earth's temperatures into a colder environment while wiping out the remnants of the human race in the process. The Chimera's victory was foiled by the former Sentinel Joseph Capelli, who managed to close the wormhole and reverse the Chimera's terraforming process. With the wormhole cut off from Earth, the Chimera became severely disorganized - seemingly as a result of losing their hive mind connection to the Pure Chimera - and became more vulnerable to surviving human resistance forces.

Within time, the human race succeeded in wiping out the Chimera and began rebuilding their civilization.
