As they needed a lot of Force-sensitive beings for fueling their starships and pursue their conquest of the galaxy, the Rakata became a well known practitioners of slavery which was not only built on it but also dependent on it. They also used a lot of their slaves as a labor force to build their greatest achievements, as for the Star Forge, a massive shipyard that used the energy from stars to fuel itself. Some of the races they used included Niktos, Duros, Hutts, Humans, Selkath and many more. Eventually, slavery toppled their Empire when their subjects banded together in massive revolts.

The slaves were stripped of their identities and a letter of the aurebesh alphabet was assigned to each of them, and then tattooed in various places of their bodies in case they were dismembered. Slaves who displeased the Rakata were often eaten by their ruthless masters.

In addition, when a slave particularly strong in the Force was discovered by a Rakatan Predor, the latter could train him as a Force Hound. They would become powerful Dark Side users, trained for the purpose of discovering planets highly attuned to the Force and their inhabitants for their masters.
