Senomar

Senomar was the name given to the collective group of Nine Kingdoms that made up the larger geopolitical region that held most of the concentrated political and military power in Celestus.

Indeed, if you were a member of any of the Nine Kingdoms it was common to refer to the world itself as Senomar, rather than Celestus. Such was the concentration not just of power, but of civilization as well.

Take note that while certain areas were also members of The Nine Kindoms, citizens of these places referred to themselves and their local area by its individual name rather than as being part of Senomar. The naming convention applied first to places outside ones local government, and second to an individual landmass itself.

This was because as the influence of the central kingdoms grew to comprise nine individual governments or even city-states, it led to areas outside of the borders of one landmass to be incorporated.

Thus, once the were canonized as revolving around a central Parliament of Nine Kingdoms, the identities of these places did not change.
