The Precursor race is a important part of the Star control series from the first game to the most recent. They had many great inventions such as the Su-Matra, Rainbow worlds, and recently the Precursor Flagship in the first Star control II to the Precursor Artifact found on Beta Naos In the Second Star Control II also known as project 6014.
They were last known to be roaming though the local region of the Milky way galaxy about 200000 years ago or (Circa 198,000 BCE). Its unclear when they began roaming the local region of Space but carbon dating the radioactive minerals on the outer most, rim-ward, rainbow worlds indicates they began this great journey about circa 600,000 BCE. However carbon dating the three rainbow world planets found in project 6014 This species had traveled outward from Beta Messier in addition to there inward migration to the Kessari quadrant. this indicates that the bulk of there migration did travel to the Kessari but also indicates that a small contingent had left the galaxy going in the other direction perhaps traveling to Andromeda Galaxy There Species is very much a unknown species could be Millions or perhaps billions of years old.
It is known however that the some time after Circa 198,000 BCE that the precursors had traveled off into the core-ward direction as in towards the galactic center and beyond to reach the Kessari Quadrant. Its unclear what stars were to be the exact destination they were heading to but it is known in which direction they generally went. every 50,000 years or so years the precursors would leave behind another rainbow world toxic waste dump because of there extremely developed economy from there Advanced technical abilities. it took the precursors about 400,000 years to traverse the local space region according to the Earth Starbase scientists in the mid 22nd Century CE they were not in a hurry to leave and tended to build large colonies and seed planets with exotic life forms and things like that but all these modifications to planets meant that the precursor colonies had to stick around for a few millennia here and there as they became more and more familiar with exploring the local region of space.
- According to the Slylandro of the gas giant planet known as Source, they were called "shaggy Giants" which indicates that they had fur and would have been a kind of Mammal.
- According to Commander Hayes of the Earth Star Base, the Precursors were indeed giants but he was not sure if they were more like a Dinosaur or more like a Wholly mammoth but after talking to the Slylandro it appears they were in fact more like a wholly mammoth.
