Sogundai is a small terrestrial planet orbiting a binary star system. It once supported a complex ecology, but now has virtualy no liquid water and only a sparce atmosphere with little oxygen content. While otherwise unremarkable, the planet contains a large number of towering structures of unkown function build by a long extinct race, and has become a site of great interest for human and citali xenopaleontologists.
Although it is inhabited by both humans and citali, humans have claimed the world as their territory under current space law the citali do not dispute this claim so long as the humans do not disturb their research efforts.
The planet was discovered by a roruk scouting ship during a starmapping expedition, but due to the planet's limited resources and development potential, the roruk never made more than cursory scans of its surface or the structures. It was only years later when human traders heard about discovery and sold the location to the University of Terra that any real interest in the planet developed. Later and quite independently the citali established a research site on what seemed to be an unremarkable location, however due to their rapid and single minded developement at this site, it is believed to be more important than originaly thought.
Current human research efforts center around the largest cluster of structures, located in the basin of a large crater. Because the lower third of these structures was buried in volcanic ash when the site was found, it was dubbed "New Pompeii" by the researchers.
Initial results at the site has been unremarkable with the only broken and highly degraded machines and devices found, which provide little more information even when examined at the nanoscopic scale. Scans of the structures themselves show that they are constructed of nearly singular pieces of an unknown silicate-based composite, but give little more than a hint as to how they were constructed.
The citali research station on the other hand appears to be very active with many entry vehicles seen leaving and entering the planet's atmosphere daily. Unfortunately for the humans, the citali have been less than cooperative in sharing their results, politely refusing either an exchange of information or any offers of human assistance. All scans made of the site by humans have come up empty, not even showing the ships visible on the ground, and any human ships attempting entry to site find themselves inexplicably turned arround despite no visual or sensor evidence thereof.
Little to nothing is know about the species that built these structures. No skeletons or other biological remains have been found, so even something as basic as their appearance or rough physiology are unknown. In all communications the citali refer to the species or anything built by them as "Ciat'tat sa", and while they are officially known as "Species S-008", most of the research staff has adopted their citali name.
