Between the years of 3 ABY and 4 ABY, Boba Fett, a notable bounty hunter, and the crew led by the bounty hunter T'onga embarked on a mission. Their destination was Quantxi, a junk moon orbiting Ord Mantell, and their objective was to kill Xanak Grunseit, a Lord within the Black Sun criminal organization. T'onga's team needed Fett's expertise to locate Tarr Kligson, a cyborg fixer who could potentially assist her friend Beilert Valance, whose memories had been wiped by the Imperial Inferno Squad. Consequently, T'onga's crew journeyed to the Rishi Moon, where they fought against Fett. Eventually, the bounty hunter agreed to lend his services to T'onga, but only on the condition that she and her crew first aided him with a separate task, to which they consented.
Subsequently, the crew made contact with Grunseit, who was already a target with a death mark placed on him by the Hutt Clan. Upon discovering Fett's intention to claim the bounty, the Falleen leader Grunseit issued a bounty for Fett's capture. Grunseit and T'onga reached an agreement where they would deliver Fett to Quantxi in exchange for payment. However, Grunseit was unaware that the crew was secretly working with Fett, who in turn was employed by the current leader of the Black Sun syndicate, seeking Grunseit's demise. Upon arriving at the moon, they handed Fett over to the Black Sun forces and followed them into a structure, anticipating their payment. It was then that Grunseit revealed his deception, informing the crew that they would not receive any payment and surrounding them with E-Web heavy repeating blaster cannons.
At that precise moment, Fett, whose only requirement was to get within striking distance of Grunseit, launched a ball of Syntox, a rapidly acting neurotoxin lethal to Falleen, directly at the Black Sun leader. He also disclosed that he was working for Grunseit's cousin. The neurotoxin proved fatal to Grunseit, prompting the remaining Black Sun forces to unleash their firepower on Fett. T'onga's crew then joined forces with Fett to subdue the remaining Black Sun forces. After eliminating the opposition, Fett acknowledged that T'onga had fulfilled her part of their agreement and reciprocated by providing her with the coordinates to the fixer Tarr Kligson. He then departed aboard his ship, leaving T'onga's crew stranded on Quantxi.
