Details:

The United Nations Solar Alliance is a galactic intergovernmental world whose objective is to colonize every planet and guarantee humanity's access to the advantages of the Milky Way galaxy. It evolved from its predecessor, the United Nations, or UN. In the 22nd century, the UN Council decides to reorganize into the United Nations Solar Alliance in order to control the majority of the Milky Way galaxy. Then, in the 23rd century, the Harvester alien civilization appears from within the Milky Way galaxy, using a mothership to harvest additional natural resources and extinguish other alien planets. Harvest Empire's initial objective for harvesting was a colony called New Madeira. As a result, UNSA was put on high alert about their presence and thought that they posed a threat to humanity. As a result, they gathered all countries to form the United Nations Coalition Command to combat the threat from aliens. The Humanity-Harvester War has begun. They can fight off the Harvesters thanks to their sophisticated technological weaponry and advanced technology. Despite the fact that their alien technology is superior to human technology, humanity has emerged victorious in each mission. The largest fleet decimated the majority of the alien fleet in the 24th century, bringing the conflict to an end as it sailed for the alien homeworld. They were able to defeat a queen and bring the empire to its knees once and for all. As a result, the Humanity-Harvester conflict is over. To create their own designs, they reengineered the technologies employed by the business, industrial, economic, and environmental sectors. Peace has finally arrived, until in the 26th century, a new conflict leads to another world, a different reality. Daniel Thompson, a young man, discovered and led the organization. He required their assistance in fighting a tyrannical empire known as the Holy Britannian Empire. As a result, another war has begun in another world.
