The Burning Sultans
Nizbathan is a human-majority member state of the Sandsea Confederacy, located between the Red Canyons and the Sickle Coast. A relatively resource-poor nation, a strictly regimented culture (including compulsory military service for most citizens) helps prevent drought and starvation. The capital and largest city of Nizbathan is Kaff, which is home to some of the only non-human populations in the state, including halflings, as well as small enclaves of dwarves from the Red Canyons and of dragonborn from Bal’Teth. Prior to the formation of the Sandsea Confederacy, Nizbathan was often involved in border disputes with its neighbors, trying to claim larger supplies of resources from them. In confederation, the satraps of Nizbathan saw an opportunity to break free of their dependency on conquest for resources, and so quickly assented to Qadiva Clearstar’s proposition to ally with the other states of Sandsea.
For your own purposes, Nizbathan is also the home nation of Zeemo Thornbuck.
