Arviem 2

 was a planet visited by both Bernice Summerfield and the Seventh Doctor. There wasn't a planet Arviem 1, as RVM 1 was Renk Van Magnastein's ship and RVM 3 was his hover ship. The colonists worshipped science to an obsessive degree. Renk created the civilisation by using the Doctor to genetically engineer a pink dragon which began all life on the planet.
