Battle Thrall

The Battle Thralls of the Ur-Quan Hierarchy are the species who have pledged to serve the Ur-Quan Kzer-Za by helping them enslave other sentient races. Their duties include providing military support for the Kzer-Za and watching over slave shielded worlds while their masters pursue more important matters.

Battle Thralls have rights to travel through space and to retain some autonomy on their homeworlds. It is likely that their goverments are chosen by the Kzer-Za.

They are not allowed to make war on other Thralls or "fallow" slave species. Punishment ranges from blasting villages and cities to total annihilation, depending on the severity of the crime.
