Orsimer Prime is governed by several independent tribes with various methods of governance. There are over 300 official tribes, and upwards of 100 unofficial ones. Officially, the Council of Zuldrukh operates as the planet's government, but their reach is confined to their namesake city and they have little power in other parts of the planet. Zuldrukh is Orsimer's de facto capital and has thus been left with the task of representing the planet on a galactic scale.
The Council of Zuldrukh is an oligarchy made up of members of Zuldrukh's aristocratic families. There are seven sitting members, and once sat, it is a lifetime position.
The planet's economy is entirely self-sustaining, and apart from technology and luxury items, Orsimer imports very little. Their main exports are animal pelts and dyes, also luxury items. Outside of major cities, the "economy" is little other than a trade and bartering system.
