Xeron

Xerons were a Near-Human race that were conquered and enslaved by the Morok Empire. They were a peaceful people whose weapons had been inferior to those of their conquerors. The Moroks committed genocide against the Xerons, killing them all except for the children, who were kept as laborers. Most worked in the museum constructed by the Moroks on Xeros until they were transferred to other planets in the empire. The Doctor and his companions aided the Xerons in their successful revolution against the Moroks. (DW: The Space Museum)
