Kiros (also known as Kir III), is the third of five planets in the Kiros system, located in the Freeworlds Region of the Par'tha Expanse. Classed as a Class O world, the majority of the planet, some 92%, is covered by water. The remaining 8% is occupied by two moderately sized continents, and numerous islands and archipelagos.
While Kiros is technically a member of the Freeworlds, they are not represented on the Council. This is due, in part, to their lower level of technology (early space travel) compared to many other worlds in the Par'tha Expanse, but also because of the divided political situation on Kiros. Where most planets would develop one sentient species (ie. Humans on Earth, Vulcans, Bolians, Trill, etc), Kiros' early geological continental separation isolated the original indigenous sentients into two groups. These groups then evolved over the course of tens of thousands of years, independent from each other. Though they share distant ancestors, the A'Kir and the Kirosians are easily physically distinguishable from each other, with very different cultures, beliefs, languages, and politics.
Due to the pressure of overpopulation, elementary terraforming has begun on Kiros.
