"Thrall Rustlers are the slave traders of the Wasteland. Since slavery is about nonexistent in the wasteland, due to the fact that everyone will willingly work under slave-like circumstances voluntarily just to stay alive, Thrall Rustlers must specialize.
What is scarce in the Wasteland is special skills or attributes, so Thrall Rustlers take people who have training or exceptional beauty, bizarre mutations etc. This Thrall Rustler outpost is not so much an abode as a place where Rustlers hide their slaves-in-waiting to sell them. It is heavily guarded whenever there are any slaves inside. Although a system of confusing tunnels, daylight will seep down from cracks in the ceiling."
