A Commercial activity performed throughout the Stellar Empire on alien planets inhabited by pre-spacefaring species. Specimens of local sentient races are ambushed and stunned, to be carried off into space. Usually the utmost care is taken to not overtly damage the prisoner, and escape unseen. Any witnesses are either abducted as well, or destroyed with superior weapons. Abductees are then used either for study, documentation, or direct sale in one of Empire's commercial hubs.
