///From the author: this is a real labor of love, and certainly a bit of a headache, too - I actually stayed up past 2 or 3 in the morning a couple of times to complete all the flags and make the flag map! That said, I'm very proud of how it turned out, and I'm glad to finally have a definitive source of lore for our homeworld in 2389, which can be drawn upon as a base text for the various powers of that era and their role in the Spacers Saga
Flag Map

Background Info:
In 1989, an asteroid destroyed Phoenix, AZ, ushering in the New Space Age. This new age of exploration resulted in a solar system-spanning campaign of colonization, and by the 24th century there were settlements on hundreds of worlds across Solar Space. But it was also in that year that alien ruins were discovered buried on Saturn’s moon Titan, opening the doorway to an immense Network of ancient knowledge which brought the dream of exploring and exploiting worlds beyond our host star finally within our reach.
The most remarkable difference in the world map of 2389 is the dramatic sea level rise made inevitable by nearly six hundred years of rampant industrialization and the resultant storm of carbon emissions. The Community of Gaia (COG), established in 2097, has halted this collapse, but the new equilibrium state of global coastlines scarcely resembles that of the early 21st century. Aside from extensive climate conditioning initiatives, a massive sea wall system has been built to protect the nations along coastal regions.
There are three major power blocs on Earth: the Community of Progressive Peoples, which pushed ahead of the Union of Democratic Nations early in the 24th century as a result of the former’s partnership with the Alliance of Free Worlds, with the Alliance for the Defense of Sovereignty holding onto the third part of a more or less three-way tie for control of the planet. It is this status quo which the COG and ICA seek to maintain.
The CPP is a powerhouse largely thanks to its power over 24th century terrestrial industry, which grants them immense influence over both terrestrial and interplanetary politics. These nations maintain a strong presence in the slowly revitalizing industrial sector of the late 24th century, with activities in Europe, America, and East Asia balancing out with agricultural and mining dividends from North Africa, Brazil, and the Union of Terra Australis, which was also the first region outside of Europe to leave the COG sphere.
On that note, the CPP is closely tied to the Progressive Union of Gaia (PUG), a counterweight to the COG which emerged in the early 24th century to offer an alternative to the ICA’s control over Earth. Their controlling interest in the near-endless supplies of helium fuel harvested from Saturn and Uranus, are among the most profitable in Solar Space, although their communal economics typically eschew this fact.
On the other end of the cultural spectrum is the Union, which retains a powerful influence over interplanetary politics and economics thanks largely to its partnership with the Interplanetary Commercial Administration, the intergovernmental organization tasked with overseeing all business beyond Earth’s atmosphere. With Earthside ventures ranging from the seagoing aquaculture of the Republic of Pacifica to the East African Federation’s shares in industry on Io, the Union remains the single largest terrestrial investor in the ICA, due mostly to all of its immense influence in the manufacturing sector.
The ADS holds a seat at the table with the other major terrestrial powers thanks to both its projects in South and Southeast Asia and the West African Confederation and to its numerous offworld ventures, which make it essentially the inner solar system’s bread basket. Thanks to the predominance of emigrants originating from the former Republic of Brazil, Portuguese was one of the most-spoken languages in Solar Space (aside from English) by the late 24th century, second only to a few from Africa, Tibet, and India.
Aside from these three power blocs are a handful of nation-states which are essentially wholly-owned subsidiaries of the United Nations of Mars. A notable example is the Siberian Confederacy, which maintains the massively productive Siberian Produce Amalgamated, a vast agricultural conglomerate which is second only to the ADS in terms of output. Other examples include Martian Alaska, Angola, and the Sahel, all of which act as a home away from home for wealthy Martians, and Federal Esperanza, the only foreign holding in Antarctica. Esperanza funnels mineral wealth to Mars, and is a source of controversy for their presence on Earth.
All told, the power blocs contend with one another much as in the Cold War of the late 20th century. With other major powers of Solar Space, including the United Nations of Mars, the Confederation of the Main Belt, and the Alliance in a state of constant tension, this Cold War could soon go hot.
Now it seems that the long-simmering conflict between the ICA and the Alliance could erupt into violence once more, leaving Terran nation-states jockeying for influence among the nascent powers of Solar Space. As this brewing interplanetary maelstrom grows in scale, the situation for a new generation of soldiers about to take up the defense of the worlds throughout Solar Space seems more and more dire.
