The Scourge is the largest, best organized and most violent prison gang on Belsavis. Its members are suspected not only of the deaths of multiple prisoners, but also of several Republic guards. It is rumored the Scourge gang controls all illicit trade within the prison. Anyone who wishes to survive on Belsavis must submit to the Scourge's authority.
The gang's vicious leader is Jaardu Raax, a Rodian crime lord and mass murderer. Jaardu killed over three hundred innocent citizens when he set off thermal detonators on a busy Coruscant market street while trying to escape Republic law enforcement. He was given a life sentence on Belsavis, but that has not stopped his violent ways.
