The Imperial States of Free Pax States is a hereditary, absolute, federal monarchy comprising of eight states, four special administrative regions, a territory, and a district. The nation is situated in Southeast Yasteria, just south of Packilvania, and just north of Justelvard. The nation shares a land border with Packilvania and Justelvard though the Free Pax States is largely comprised of an archipelago. The nation has a mostly tropical climate with the exception of the Kaoghoni Desert in its northwest. The Imperial States has a diverse population of approximately 209 million.

The Imperial States traces its origins from the Alliance of Southeast Yasterean Kingdoms which was a military pact formed in 1897 by the kingdoms of Kaoghon, Lazako, Astlyon, Masako, Peregrinia, and Tilden after the formation of Morstopackia. These Southeast Yasterean nations sought to promote culture, avoid conflict, promote trade, and provide a united front given the rising influence of Morstopackia to their north and south.
