Kaldor City

Kaldor City is a humanoid city of the future on an unnamed alien world, created by Chris Boucher in his Doctor Who television serial The Robots of Death broadcast in 1977, and reused in his 1999 Doctor Who novel Corpse Marker (a Past Doctor Adventure). It is also the setting and title of a series of audio plays released on CD, produced by Magic Bullet Productions, that include elements from both Doctor Who and Blake's 7 (Boucher was Script Editor on all four seasons of Blake's 7).

Some of the plays in the series also feature the Fendahl: a race of creatures also created by Boucher in 1977, in the Doctor Who television serial Image of the Fendahl.

Kaldor City is a major city "on a corrupt world governed by an all-powerful Company, where the rich scheme in mansions filled with robot slaves, the poor scrabble for survival in the Sewerpits, the Security forces are out of control and terrorism is a daily fact of life". The city was first mentioned in The Robots of Death as the home base of a "storm mine" touring the desert searching for and mining precious minerals from within the sands, with the crew working on commission for the Company.

The society shown in The Robots of Death is one where higher class "founding families" (presumably a reference to the families that founded the colony planet) have hit financial difficulties and are forced to work with (and sometimes subordinate to) citizens who have achieved their power, influence and wealth through their own hard work and scheming. This has led to a certain amount of resentment between the new and old money, mirroring the decline in the financial power of the gentry in England. The society is also highly reliant on the use of robots at all levels, with three class of robot in use: Dum robots are for menial work, and are unable to speak; Voc robots are the next level up, and can speak, and have limited reasoning capabilities; Super-Voc robots are the most advanced, and can be used to monitor complex activities including the day-to-day activities of other, lower class robots. Each robot is given a designation based on its class (for example D-84 is a Dum class robot and SV-7 is a Super-Voc) and is programmed with a variant on Asimov's Three Laws of Robotics.
