In 2155, the Tholians used slave labor to strip the USS Defiant's technology. At the time of the ISS Enterprise's arrival, there were thirteen slaves aboard, although none were Terran. After Jonathan Archer captured the vessel, twelve of the slaves were captured, though the slavemaster, Slar escaped and began attack the Terrans. Archer began interrogating the slaves, starting with an unnamed alien slave, to find out who was attacking his crew.
