Qwarm

The Qwarm is a society of professional assassins based in Alan Dean Foster's fictional Humanx Commonwealth universe.

The group itself isn’t outlawed, though individual members can be barred from certain planets. Members of the society commonly dress all in black and sport silver metal skull and crossbones devices to advertise the guild allegiance. They are commonly described as being fearless in the face of death. Qwarm work both in groups and singly and are often hired by the rich to serve as bodyguards, though they normally prefer to spend their time hunting prey rather than protecting employers.
