The B'omarr pipe nalargon represented a type of musical instrument used by the monks belonging to the B'omarr Order. Often referred to as an "engine of unfaithful rhapsody," it was a widely held belief that only members of the B'omarr Order possessed the ability to control the instrument. However, contrary to popular opinion, the brilliant genetic terrorist known as Zeta Magnus successfully learned to play this specific nalargon and regarded it as his most cherished instrument.
