Unlimited Alternatives/Nations

THE MODERN WORLD

Sinju Union
It's now a single state so I'm not going to list every single of the dozens of nations that are members of the Sinju Union.

The Sinju Union actually became a full superstate in the aftermath of WW2. Large areas have been devastated, and certain major cities like Hapcheon have been completely abandoned, leaving the inhabitants to live amongst the rubble.

Barujaya
An ally of the Sinju Union.

Kewhira
Luckily, an ally of the Sinju Union, enabling them continued use of the valuable Canal.

Cosentina
A Gungjun ally of the Sinju Union. They have succeeded in reclaiming the lands that they claim.

Buyeo Commonwealth
The Buyeo Commonwealth has become a major world power due to their ownership of nuclear-scrubbing nanotechnology and similar treatments for radiation poisoning. With these technologies developed shortly after WW2 and largely untouched by the fighting, Buyeo soon became the forefront of the global recovery effort. Brilliant political manoeuvring and protectionism resulted in Buyeo becoming the sole supplier of radiation-treatment technology until the 2060s, bringing it amongst the world powers despite its small size and stature. Buyeo also pioneered in robotics and weapons technology, though not to the extent of its northern neighbour.

As Akitsukuni spread its hegemony over Uju in the period after WW3, relations between the Empire and the Commonwealth soon soured as the Empire continuously attempted to bring Buyeo into its SDA. Territorial disputes and espionage resulting in Akitsukuni also attaining the nuclear-scrubbing technology ruined relations entirely, and imposing walls and border checkpoints have been erected between both sides. In whatever regions where walls are infeasible, military patrols continuously stalk through mountain passes and irradiated swamps, occasionally skirmishing with each other in a quiet border war.

Relations plummeted 15 years ago after a partially-botched attempt at effecting a coup in the Buyeoan government by Akitsukunese special forces resulted in the deaths of over 100 innocent people in a massive explosion. A more hardline government then took over.

Strategic Defence Alliance
The SDA is the world's largest military alliance to date, and is led by Akitsukuni. Almost all of the member states are also members of the Co-Prosperity Sphere, an economic organisation.

Akitsukuni
The rise of Akitsukuni began as soon as the Second World War ended.

Akitsukuni now controls most of the Uju Continent.

Some areas have been devastated by nuclear and are walled off cities, like Suiattle, which is entirely walled off. People still live within. Heian has been destroyed, and the capital is now in Niihama.

They have TSFs, and Ghost in the Shell weaponry.

Asturias
The first non-Uju nation to join the SDA, Asturias' membership is a clear sign of the SDA's global aims. It is almost constantly embroiled in internal anti-insurgent operations, but the stationing of SDA troops in their new Gungjun ally is a cause for concern for nearby allies of Sinju, like Cosentina.

Yoju Cooperation Organisation
The Yoju Cooperation Organisation was formed after Azamia's capital was hit with a terrorist nuclear attack, following wars that raged across the region. They are currently embroiled in a decade-long conflict to seize precious water resources from Deshret, as well as the remaining oil fields in the region.

The YCU is aligned with the SDA, and is heavily funded and armed by them.

Deshret
Currently embroiled in abovementioned war. They were a rising power before they were invaded, however.

Dayganistan
Invaded Indrayana after the zero-sum Indrayana-Arjunapur War. After the collapse of Arjunapur, Dayganistan has to deal with the competing warlords and instability of the region, and is gearing up to finally invade their historical rival.

Dayganistan also has to deal with the YCO on its northern border.

Arjunapur
Arjunapur fractured into numerous ethnic-based states, kingdoms and warlord realms after WW3 and the war with Indrayana. There is no longer a useful central government as warlords war amongst each other for dominance or ethnic groups battle for independence from a state that has ceased to exist. Ironically, the Southern Isles are still home to the descendants of the original government and the remnants of whatever few loyalist military forces, but reclaiming the mainland is a faraway dream.

Hanju
Once the rising star and leader of the communist world, Hanju has long fallen from grace and is currently split into the remnant communist government, a right-wing nation attempting to regain world prestige and power, and a nation that is essentially a puppet of Akitsukuni. Not to mention the large northern portion of the nation that is a devastated wasteland plagued by warlords and near-post-apocalyptic conditions.

Hanju Empire
An autocratic nation led by Autarch Han Jae-Moon, seeking to rebuild Hanju as a world superpower. They are the most powerful of the three Hanju states, and control the south coast.

United Republic of Hanju
A democracy formed and propped up by the Sinju Union and Akitsukuni after the invasion in WW2. Allied with Akitsukuni, they control the west coast and are the weakest of the three states, though Akitsukunese bases and forces are present in the URH to make others think twice.

Revolutionary Republic of Hanju
The remnants of the original Hanju, mainly located on the west coast.

Hanju Exclusion Zone
The irradiated zone is now home to numerous warlords, small communities and villagers of survivors eking out a meagre existence, sometimes in pre-industrial conditions in a largely post-apocalyptic wasteland. Rumours of vehicle-based combat between roving gangs have also emerged from the area, as well as a legendary figure known as "Mad Myung".
