Duefgrin was a male teenage Brolf living on Barlok who was part of the assassination plot against several negotiators in a Corporate Alliance and Brolfi government mining dispute. Some of the negotiaters included Passel Argente, Guildmaster Gilfrome and Jedi Master Jorus C'baoth. Other items the young Brolfi conspirators collected for the missile construct were explosives, a stabilization system, and alloy packing cylinders.
