Member of a Ferengi delegation sent to negotiate for the rights to the Barzan wormhole in 2366. Dr. Arridor was responsible for the distillation of a Ferengi pyrocyte which DaiMon Goss used to poison the Federation ambassador, Dr. Mendoza. Dr. Arridor was one of the crew of the Ferengi shuttle sent to investigate the Barzan wormhole; he was lost in the distant Delta Quadrant when one terminus of the wormhole changed location. Arridor and Kol became stranded in the Delta Quadrant when the other terminus of the Barzan wormhole also changed position. The two crash-landed on the Takarian homeworld and assumed the role of the Great Sages from Takarian mythology. In 2373, the U.S.S. Voyager happened upon the planet and forced Arridor and Kol to leave. When they attempted to return to the Takarian planet, their shuttle was pulled into the Barzan wormhole by a gravitational eddy. Their actions knocked the wormhole off of its subspace axis so that both of its endpoints jumped around erratically. The fate of Arridor and the shuttle remains unknown.
