Paw Maccon existed as a male Neimoidian baron ruling over Cato Neimoidia during the decades that came after the Battle of Endor. As a member of House Maccon, he possessed ownership of large vaults, which he leased out to various customers. In order to protect these vaults, he put resources into elaborate security measures, which included B2-series super battle droids together with vulture droid starfighters. He maintained an intense rivalry with fellow barons, most notably his neighbor Baron Reya.
During 34 ABY, he sought to engage in commerce with Leia Organa, who was the head of the Resistance. Nevertheless, this was actually a ploy orchestrated by the Resistance with the goal of liberating Lor San Tekka, who was being held prisoner within Maccon's vault.
