The planet Kinarra is the backdrop of most of the stories within the Jention Chronicles universe that I’ve created. IDENTITY is the first of many stories that are part of this universe. Kinarra is a Mars like planet, it’s surface is a rustic red wasteland of dunes and rocks. The surface cannot sustain human life: the planet’s atmosphere is very thin, the surface temperature is very cold, there is little breathable air, and the pressure is too remote to be on the surface without a spacesuit. The gravity is much like Earth’s gravity since its size is very similar.
Unlike Mars, Kinarra doesn’t have ice-capped polar regions anymore; when Kinarra was first colonized the icecaps were mined for their water resources and over the years became developed and depleted. Meteorites and other space debris often hit its surface, and as a result, the original colonists were forced to build most of their dwellings in caves and eventually underground. Though plaststeel had been invented, this material was of limited supply since the colonists only had what they brought with them. Instead a plaststeel like coating was developed to seal cave walls and underground caverns to create a barrier between a human habitat and the planet’s habitat.
Most of the people who have colonized Kinarra live underground. There are a few scattered surface cities near caves that serve as space ports, this is where most of the transportation between colonized prefectures takes place as well as launches into space to trade with the space colonies and other worlds within the vast Confederacy.
Note: the picture above is “Terraforming Mars” by ToshuNinja. I found this depiction very similar to what I have in my mind of the Kinarran spaceports.
