Helot

In the alternate timeline where Khan Noonien Singh won the Eugenics Wars, a Helot is a conscripted crewperson in the Earthfleet of the Children of Khan. Helots had few rights aboard Earthfleet ships, and were generally treated as little more than slaves; alien crewmembers from various races subjugated by Earth (including Trills such as Ezri Tigan, serving on the starship Defiance) were often pressed into service as Helots.
