The Faceless Ones were once thirteen Founders who were rejected from the Great Link. The Faceless Ones despised the idea of a harmonious society. Instead they wanted to rule it. The Founders exiled them from the Great Link and removed their ability to take solid form. After being exiled the Faceless Ones fled from the Gamma Quadrant and started a new empire in the Khazan Cluster.

Needing a useful working force the Faceless Ones created two races to serve them. The Hybasii much like the Vorta, were created as working class. Unlike the Vorta, the Faceless Ones created twenty four different genetic vertices of the Hybasii to fit a specific task. They also created a warrior race known as the Lowbasii to help defend their newly created empire.
