欧盟（EU）:最早是一个集政治实体和经济实体于一身、在世界上具有重要影响的区域一体化组织。大崩溃之后，受政治、经济、环境影响，同时也是为了应对泛亚联盟的冲击，欧盟逐步脱离美国影响，寻求各方面的独立自主，欧盟内部一体化程度进一步加深，最终成为了一个由法德主导的，庞大的政治、经济、军事一体化组织。是欧洲最具影响力的政治实体。

泛亚联盟（PAC):泛亚联盟是一个崛起于大崩溃之后的区域经济、军事合作组织，其主要由中俄两国为核心。2091年，大崩溃结束一年后，中国、俄罗斯、印度、韩国、日本在上海 签署《上海宣言》。泛亚联盟正式成立。随后开始了横跨整个亚洲的资源整合调配。并在第一个十年中取得了巨大成功。随着经济的复苏，泛亚联盟的领导人们也开始着眼与全球战略，以寻求霸主地位。

新美国：大崩溃末期，既黄石火山喷发之后形成的新兴国家，其主要领土范围为旧美国东海岸、美国中部及极少部分美国西海岸，继承了旧美国绝大多数的政治、军事影响力。但同时也是大崩溃时期受损最为严重的地区。

孤星共和国：以独立后的加利福利亚州、德克萨斯州为基础，几乎占据了旧美国的西海岸，其主要势力范围是旧美国德克萨斯州、亚利桑那州、新墨西哥州、加利福利亚州、内华达州。虽然其领土仅占旧美国的百分之三十，等由于地理因素，在大崩溃中损失较小。是泛亚联盟在太平洋方向的主要军事威胁。

European Union (EU):
Originally a political and economic entity with significant global influence as a regional integration organization. After the Great Collapse, driven by political, economic, and environmental pressures—and in response to the rise of the Pan-Asian Coalition—the EU gradually distanced itself from U.S. influence and pursued comprehensive autonomy. Internal integration deepened, ultimately transforming the EU into a vast political, economic, and military union dominated by France and Germany. It stands as Europe’s most influential political entity.

Pan-Asian Coalition (PAC):
A regional economic and military cooperative organization that emerged after the Great Collapse, with China and Russia at its core. In 2091, one year after the Great Collapse ended, China, Russia, India, South Korea, and Japan signed the *Shanghai Declaration* in Shanghai, formally establishing the PAC. It subsequently initiated resource integration and coordination across the entire Asian continent, achieving remarkable success within its first decade. As economies recovered, PAC leaders shifted their focus to global strategy, seeking hegemonic dominance.

New America:
A nascent nation formed in the late stages of the Great Collapse following the eruption of the Yellowstone volcano. Its territory encompasses the former U.S. East Coast, central regions, and minimal portions of the West Coast. While inheriting the majority of the former United States’ political and military influence, it also suffered the most severe devastation during the Great Collapse.

Lone Star Republic:
Founded on the independent states of California and Texas, it occupies nearly the entirety of the former U.S. West Coast. Its sphere of influence includes the former states of Texas, Arizona, New Mexico, California, and Nevada. Though its territory constitutes only 30% of the former United States, geographical advantages minimized its losses during the Great Collapse. It now serves as the PAC’s primary military threat in the Pacific theater.
