**Earth**, also known as **Sol d**, is the third planet in the Sol System and the homeworld of the human race. It is the presumptive capital of the Milky Way Galaxy, and a hub for technology, industry, and culture. It is currently the most populous planet in the galaxy, numbering at more than 15 billion citizens. All current human powers can be traced back to Earth, and the planet holds significant influence across the galaxy.

Earth is the first planet known to support life, and for a significant portion of human history, humans could not break its gravity. With the onset of the first and second Space Ages, humanity could expand past Earth and the Sol system, and colonized numerous other planets and systems.

During Earths recent history, the planet has suffered resource depletion and exploitation, a climate crisis, and an extinction event during humanities industrial revolutions and space ages. In particular, the Holocene Extinction event occured between the 20th and 22nd centuries, due to human activity across the planet. The climactic climate crisis led to global warming along with massive hurricanes and storms across the planet. Category 6 and 7 hurricanes regularly hit vulnerable coastal areas during the late 2000s and early to mid 2100s.

## History

### Prehistory

Earth was formed 4.6 billion years ago, and the first microbes and life on Earth sprung up around 3.9 billion years ago. Around 250,000 years ago, the Homo Zainus race evolved on Earth. The species was highly intelligent, and discovered spacetravel a mere milennium after the species first arose. Supercities developed on Earth as the Homo Zainus race colonized many planets and systems around the galaxy. United under the banner of the Terran Federation, the Homo Zainus race flourished and thrived for milenniums.

Humans first emerged 200,000 years ago, and were taken with great interest by the government of the Terran Federation. The continent of Africa was eventually given to them as a sanctuary and protected by the Terrans. One Terran leader even said "Once our race is gone, I hope the Sapiens can carry our torch onward one day." A faction within the federation, calling themselves the Trappists, distrusted humans, believing they could advance past and destroy the Homo Zainus race.

Around 60,000 years ago, the "golden age" of the Homo Zainus was seemingly at an end. The Terran Federation was proving itself to be increasingly unreliable to resolve issues between its political factions. The Republican "Orions" began to rise within the federation from the highly advanced city planets and technological centers of the galaxy, while the "Trappists" mostly occupied the poorer regions of the galaxy whose people believed in a single strong leader to lift them out of their suffering.

### Terran Civil War

By 53,210 B.C, the populace of the poorer systems that supported the Trappists have reached their breaking point. Facing a lack of support from their democratic government, revolts began around the Perseus Arm and the Outer Rim. The Trappists officially broke relations with the Terran Congress, and began a revolution across the Outer Rim, Perseus Arm, and parts of the Sagittarius Arm. The revolution soon escalated into a full on civil war, as the Trappists reformed their military, began starship construction, and began preparing for official secession from the Terran Federation.

Five years after the first revolts began, the Orion faction also broke with the Terran Federation, and began organizing a widespread revolution throughout the rich areas of the federation. Rich planets and systems around the Sol System declared independence as the Orion Federation, a more perfect democratic federation in the eyes of its supporters. Much of the Terran military sided with the Orions, and those who remained loyal found themselves undersupplied and underequipped by a collapsing rump state. The Trappist Empire was proclaimed in the Arcturus star system, and formalized a military and political system, becoming a unitary state under an absolute monarchy.

On the eve of 53,197 B.C, the remnants of the Terran Federation collapsed and were occupied. Earth itself became the new capital of the Orion Federation, choosing to embrace its roots as an Earth power. The Trappist Empire opposed Earths influence on the rest of the galaxy, however, and established its capital at Trappos (present day TRAPPIST-1e). Both entities were then locked into a galaxy wide cold war.

### Zainus Cold War

The two Zainus factions began intense competition for resources and influence in the galaxy. The Orions in particular expanded their federation greatly, acquiring and colonizing hundreds of new systems and integrating them into their federal system. The Trappist Empire competed with similarly colonizing systems, but was also often forced to quell dissent within its borders. During the cold war, over 956 million defectors would cross the border into the Orion Federation, with millions more starting small scale insurgencies against their absolute monarchy.

During the expansions of their empires, both factions would eventually discover Nesta, a lush planet with many natural resources located in the Sagittarius Arm, right between the two factions borders.
