Overview
Reiver is a species of sapient silicon-based lifeforms native to the icy moon of Reiva of the Palioxis Starfield. The Reiver tend to look similar to a select few exotic carbon-based species, through their entire anatomy is vastly different in all forms. The Reiver are one of the select few terrestrial species which are able to thrive in the vacuum of cold space, as a result of their alien biochemistry. This has made the initial space travel of the Reiver far easier, as there has been no need to wear specialized space suits. Also as a result of their silicon-based nature, they possess a far more intricate understanding of the nature of existence and such. The prime reason for this is a special organ present in a select few silicon-based organisms, making them more intelligent than any carbon-based species could hope to be. This hasn't made them completely oblivious to mistakes however, as indicated by their first spaceflight mission, in which many critical mistakes were ignored.

The Reivers have taken themselves all across the Palioxis Starfield, founding dozens of vast interstellar civilizations which have shaped the entire political landscape of the Starfield. The largest of these is Stardom of Masan, which also has full authority over Reiva. As a consequence, the Stardom of Masan is the most important of the nations crated by the Reivers. The technology of Reivers used to achieve interstellar travel is vastly similar to that of Quantum Shift Drives, though some key mechanics of them are fairly different. These superluminal drives are known as the Hakea to the Reivers. Reivers also favor special engines known as the Zantea Engines as for sublight travel. The exact ways on how they operate still perplex many scientists, though these can accelerate a spacecraft to half the velocity of light in a millisecond. The Reiver also do not possess theoretical knowledge of them, as they are reverse-engineered from a small alien shuttle that crashed on their home moon.

Instead of regular clothing, the Reiver always appear to be wearing highly specialised bio-mechanical suits. To the Reivers, these suits are known as the Hava, and they provide adequate protection against any and all environmental risks. These are made of pure refined varium, however they are also protected by highly sophisticated deflector shield generators. These suits also include a small Zantea Engine, which, as a result of its compact size, can only accelerate a Hava to around ten thousand kilometers per second, far below the speed of light. The Hava were invented in the midst of their interplanetary expansion to other worlds within their home system, as a modern replacement for typical 'clothing' at the time, which consisted of a full suit made out of organic materials. The earliest iterations of the Hava were rudimentary and clunky, but they've been significantly improved over the course of many thousands of years.

Society
Even in the earliest days, the Reiver have separated them into specific clans. Many of them would be vastly different, as some would have unique skills other did not. One clan could have extended knowledge in technology, while an other one could have skills in taming the native fauna of Reiva. These clans would compete with one another, until they developed into advanced interplanetary nations. These interplanetary nations would see the first great unification of their species, with a vast confederacy formed between seven civilizations. This would go on to reshape the society of the Reiver, as they were much more welcoming to other nations. Eventually, the Reiver would then on be united into one singular civilization. As expected, over time it broke down into dozens of others, which make up the current Reiver civilizations.
