Unidentified beta trawler

Beta trawler refers to an unidentified male human who, along with a human companion and a Quarren companion, threatened an unidentified Mythrol in a bar. He did not speak during the encounter, allowing the others in the party to make the verbal threats. During this incident, a Mandalorian bounty hunter arrived to collect a bounty on the Mythrol. The human, along with his two companions, threatened the Mandalorian, and a fight ensued, during which the Mandlorian incapacitated all three of them.
