- "The Bpfasshi don't like Jedi. They had some trouble with Dark Jedi during the Clone Wars, and chased them as far as Dagobah."
- ―Leia Organa Solo, to Luke Skywalker
In 700 BBY, a cult of Bpfasshi Dark Jedi tried to establish themselves throughout the Bpfassh system. A Jedi task force engaged and killed them, with the Jedi Knight Minch killing their leader on Dagobah.
During the Clone Wars, another group of Bpfasshi Dark Jedi were responsible for a rampage of terror and destruction throughout the Sluis sector. The Jedi Order sent task force led by Yoda was sent to stop them and quell the insurrection in the Bpfassh system. Yoda pursued and killed one of the Dark Jedi that had kidnapped smuggler Jorj Car'das. The Bpfasshi maintained a strong disliking for all Jedi since those events.
