The Xerons are a sapient species native to the planet Xeros. They are externally distinguishable from Humans only by their overly long, curved eyebrows. Their planet was once conquered by the Morok Empire, which exterminated the adult population and enslaved the new generations. After the decline of the Empire, the Morok presence on Xeros eventually weakened enough, allowing a successful revolution that let the Xerons claim back their home world.
