Approximately three hundred years ago the quarians created the geth, a species of rudimentary artificial intelligence, to serve as an efficient source of manual labor. However, the geth rebelled against their quarian masters and drove them into exile. Now the quarians wander the galaxy in a flotilla of salvaged ships, secondhand vessels, and recycled technology. Other species tend to look down on the quarians, seeing them as scavengers and condemning them for unleashing a dangerous synthetic life form on the rest of the galaxy.
