Tsarina

Tsarina is a barren planet that is also host to an extensive and complete, but defunct, planetary supercomputer. It was claimed by the same small startup as those who colonized Temno, though the Neyanta claim to be responsible for its creation. Their own records of their past support this claim. 
== Description ==
Tsarina, less popularly known as Metalia, was initially believed to be an unremarkable barren planet with significant metal content, much like if Mercury in the Sol system were in Mars' place. The inexplicably maintained breathable atmosphere was marked as unusual, and the planet and its moons were added to the auction catalog and picked up for a low price by a colony startup along with the Netepli system. 
When tested by impact probes, the first caused the entire surface of the planet to ring as though it was hollow. The second hit an intersection between two surface plates, causing massive amounts of dirt to fall between them and spread apart. 
- 
also less popularly known as Metalia, was thought to be an unremarkable, dry, and metal rich world with a breathable atmosphere very similar to Bastion and was subsequently marked for mining. That is, until it was actually surveyed for mining. 
Impact probe data revealed a hard shell surrounding a massive amount of machinery that extended down for hundreds of kilometers.The machinery itself was twice as thick as the shell and made from iron and steel or alloys of unknown composition, and below that was the actual planet. 
Aside from this data it also shook the surface of the planet, causing dust and dirt to fill the crevices in the planet's outer shell and revealing the plates that made up the outside. 
Immediately after this discovery, the plans for mining were canceled, and study went underway. Despite having been studied for decades, no useful information has come from the world despite the combined efforts of both the human race and the neyanta. 
Theories as to what its purpose was range from a computation complex to automated upkeep of the planet's environment, but none can be definitively proven given the deterioration of the structures. 
It was opened to public habitation and civilian mining following the near abandonment of the study. Civilians are legally required to report any working or intact examples of technology on or in the planet to local government. 
== Habitation ==
Human habitats on Empress exist both on top of the surface regolith and deep below the ground on the underside of the shell. The most notable of these is Metalia Underground, and is the source of the alternative name of the planet. 
It hangs from the rim of a gap in the plates that caused a fairly large amount of dirt and rock to fall into the inside of the planet. It is the single largest settlement on Empress, and has been described as resembling an inverted skyscraper. Category:Planets
