Arviem 2

 was a planet that Bernice Summerfield and the Seventh Doctor once visited. There wasn't a planet Arviem 1, as Arviem 1 was Renk Van Magnastein's ship and Arviem 3 was his hover ship. The colonists worshiped science to an obsessive degree. Renk had created the civilisation by using the Seventh Doctor. (AUDIO: The Revolution)
