Casunair
In ancient North Yazland a Casunair was a Rausin form of inter-city government. A Casunair is similar to a league of cities unified under a common interest or leader. Casunairs vary in their centralization from one to another, but the basic commonalities include: an alliance based on mutual interest, some sort of figurehead (not always with executive power), and an agreement of mutual defense. Casunairs were common among the Rausin peoples, and would even spread beyond the Rausin to peoples such as the North Yasgans.
History
The exact historical origins of Casunairs are unknown. They likely came about as a way to mutually aid other cities in the event of plague, famine, or foreign raids. Eventually becoming widespread among the Rausin. The most well documented Casunairs are of the Zaupic Rausin, with what little records exist, the Zaupic Rausin seemed to have an extensive Casunair that stretched from Ziursun to Nalcaun, known after its existence as the Zaupic league. Various foreign and native sources describe the Zaupic league as somewhere between a unified state and a influential confederation. The Zaupic league was made up of X major cities, all of whom would gather together and elect one of their own as Varšaun, some variety of ruler who would serve for one year. The responsibilities of the Varšaun are mostly unknown, but they seemed to be responsible for coordinating religious ceremonies and building projects across the Casunair.
Following the Yasgan migrations, Casunairs would slowly begin to phase out as various Rausin groups were either replaced or assimilated. Similar structures, largely believed to be derived from Casunairs, would continue to endure only in Jozunia among the North Yasgans. As various Rausin traditions faded away following the collapse of Bronze Age civilization in North Yazland, many records of the systems of government employed by the Rausin were either destroyed or lost.
