Fafe
A slave not even used for labor, valuable primarily as a body that may be taken at any time, for use as life extension or disguise, for time traveling criminals. However, some slaves grew drugs on their planets; some even were not allowed to grow anything else, and were forced to eat horrible things created by time travel. Trillions of slaves on trillions of planets had trillions of kidnapped instances of Apollo Atreides, as a fetus, as their only food.
