Era 75, the era which brought to the advancement of humankind's technological prowess. The era where different types of spacecraft were made and the beginning of humankind's journey into space to create a new living environment due to the increasing population on Earth and its exhaustion of resources. The inhabitants of the earth created a new Habitat in space where Humans could live, the Habitat is called a Colony, for 400 years, Space Colonies were made and a new government was established for the Colonies, and thus ends the 75th era.

Era 76, the era where the inhabitants of earth banded together in a single alliance, and also the era where the space colonies announced their independence from the Earth Alliance.

In this era, a conflict between the Earth Alliance and the Space Colonies occurred, which brought out the first Space Warfare between Earth and the newly established Space Colonies. Warships, Carriers, and Fighters made for Space Warfare were constructed from both factions to combat each other in this conflict.

The conflict between Earth and the Space Colonies continued, and this brought out the development of a new construct that is technologically advanced and would tip the scale of the ongoing conflict between both factions, the constructs were named Mobile Suits. Gigantic humanoid robots which are operated by Human pilots. These Mobile Suits were developed by both factions in varying types, Mobile Suits that are made to dominate in space combat. The development of these Mobile Suits further incited both factions and thus the conflict escalated to a full-scale war, called the Genesis War

The war soon became a battle of attrition, exhausting the resources and manpower of both sides, the Space Colonies have lesser manpower but made up for it for their advanced technology which the Earth Alliance was lacking. As the war continued, the Earth Alliance and Space Colonies were forced to create a peace treaty, due to the war going nowhere and the risk of the extinction of humankind

After the war the Colonies and the Earth Alliance worked together on a project to create a new generation of Humans, who are genetically enhanced to have increased brain power and stronger and faster bodies that are virtually immune to most diseases, this was called Project Fate. The Earth Alliance and the Space Colonies worked on this project for two decades, researching and enhancing the human genetics, which would create a type of Super Human which would later be called Transhuman, a new type of Human which surpasses the old types which are called Naturals.

The Transhumans were sent to the Colonies because of the advanced facilities that are located there, each transhuman was further manipulated genetically to increase their life span and unlock special capabilities, though nothing lasts forever.

40 years after the start of Project Eve, a tension between the Earth Alliance and the Space Colonies occurred, the organization responsible for creating Transhumans was attacked by different factions from the Earth Alliance, massacring many Innocents, scientists and Transhumans alike who are coped up inside the organization's Headquarters.

This incited the Space Colonies, due to the reason that most of the people working in the organization are from the Space Colonies and the project is mostly supported by government bodies of the Space Colonies.

Soon a new conflict occurred between the Earth Alliance and Space Colonies, where both sides mobilized Warships and Mobile Suits. This conflict, which miraculously didn't escalate into war continued for 6 years until a certain Space Colony was bombed by the Earth Alliance, ending the lives of 240,000 Inhabitants.

The destruction of Space Colony Eureka forced the Space Colonies to form a single faction, which would be called The Space Coalition, The Coalition then declared an all-out war unto the Earth Alliance, and thus begins the start of a new era.
