Sherk was a male Human who lived during the Clone Wars, working as a customs officer in the city Tolea Biqua on the planet Genarius in the Cularin system, where he was responsible for inspecting starships that arrived in the city. In around 20 BBY, the Cularin Office of Public Safety agent Ezra Du'Re traveled to Tolea Biqua and on arrival there, she met with Sherk, who informed her of how to get into contact with the smuggler Thook Lafrell.
