Slodor

Slodor is a fictional planet located in the Cygnus X-1 system, as depicted in the "Starfarer's Almanac" series of science fiction novels. The planet is characterized by its unique atmospheric composition, which is rich in methane and sulfur compounds, giving it a distinctive orange-brown hue from orbit. Slodor's surface is primarily composed of vast, arid plains punctuated by towering crystalline formations that are thought to be the result of geological processes involving silicate-rich magma interacting with the sulfurous atmosphere.

The native inhabitants of Slodor, known as the K'tharr, are a silicon-based lifeform adapted to the planet's harsh environment. They possess a crystalline exoskeletons and communicate through a series of resonant vibrations. The K'tharr are known for their advanced understanding of geological engineering and their ability to harness geothermal energy from Slodor's active core. Their settlements are often carved directly into the planet's crystalline structures, blending seamlessly with the natural landscape.

Exploration of Slodor has been limited due to its extreme atmospheric conditions and the K'tharr's cautious approach to offworld contact. However, limited trade has been established, primarily involving rare mineral deposits unique to the planet's crust. The "Starfarer's Almanac" suggests that Slodor holds many undiscovered secrets, particularly regarding the origins of its unique crystalline formations and the K'tharr's ancient history. The planet serves as a setting for several key plot points, highlighting themes of xenobiological adaptation and the challenges of interstellar diplomacy.
