The Firrerreo are a species of near-humans from the planet Firrerre. They have two-toned hair and golden skin.
In their culture, if someone says a Firrerreo's name, the Firrerreo would be forced to serve the speaker, as saying a Firrerreo's name was a form of power.
The Firrerreo no longer live on Firrerre; after the poisoning of their world by the Empire, they were loaded onto massive colony ships for a journey to another world. One of their own, a Force-sensitive named Hethrir, betrayed his people by the command of Darth Vader. After the deaths of Darth Vader and Palpatine, Hethrir returned and intercepted the colony ships. He disengaged the drives and left the sleeping Firrerre to drift in space. He plundered the ships for the valuable equipment onboard and took the children to sell as slaves.
Hethrir kidnapped the children of Han Solo and Princess Leia Organa Solo; Anakin and the twins Jacen and Jaina. Han was on a mission on the time and did not know of the kidnappings, so Leia set out to find them herself. On her quest she stumbled upon the drifting colony ships. She asked one of the two awake Firrerre if he wanted to be freed, but he said that they would reingage the drive, heading towards the planet selected for them by the Emperor years before.
The species was considered extinct by the Yuuzhan Vong War, but, 15 years later, they were just considered scattered.
