Boss Musori was a male Chagrian who led a group of enslavers on Telerath after the conclusion of the Clone Wars. To resolve conflicts, he struck an agreement with Ken-Kiba and his spice running organization that disputes would only be settled through the use of bladed weapons, a concept they referred to as the Sword law.
In the year 19 BBY, Mors Demanna, who was considered his most skilled swordsman, informed him of an encounter with a person who had demonstrated exceptional abilities. Musori instructed Demanna to extend an offer to the stranger to join their organization, but to kill him if he declined the invitation.
Subsequently, Demanna brought Jennir to the slaver's base, where Jennir defeated him in a sword fight. Musori told the Human that he shouldn't be ashamed, because very few individuals could match Demanna's skill or honor. Jennir responded by insulting Demanna and declaring that neither he nor Musori possessed honor, given their involvement in trading the lives of sentient beings, and then departed.
Later, Dass Jennir destroyed the spice gang's refinery located on Telerath's second moon and intentionally left behind evidence that implicated Musori's gang. Consequently, the primarily T'surri gang initiated an attack using blasters on the compound, which was predominantly composed of Chagrians. Musori behaved in a cowardly and dishonorable manner, attempting to escape while sacrificing his subordinates in the ensuing battle. Ultimately, Ken-Kiba captured Musori and subsequently beheaded him, displaying his head on a pike as a warning.
