Doctor Cantryl was a male Human who operated as a crimeboss on the planet Gandle Ott in the Kathol sector during the early years of the New Republic. He controlled a criminal organization and kept accurate navigational charts of the sector. During the years that Moff Kentor Sarne was in charge of the region, Cantryl maintained a low profile due to the Moff's intolerance of criminal gangs within his territory.
