After making the first three Rubovia plays, Gordon Murray realised that in order to take Rubovia to a whole new level, major changes were required. During a two-year hiatus in production beginning around May 1956, he was assisted by fledging designer Andrew Brownfoot in a redesign, from scratch, of the whole Rubovian Legend.
Some stories from the first series were subsequently remade.
According to an interview with series creator Gordon Murray, the series is set in 1950s Central Europe, despite the main characters dressing in 18th-century style clothes. Robovians were simply "out of touch" with the world outside their country's borders.
According to an interview with series creator Gordon Murray, technology in Rubovia is different than the one used in the outside world. Rubovia has gas and steam-powered technology, clockwork-based devices, and spring-driven gramophones, but lacks electricity and common telecommunication devices, such as the telephone.
