List of Blake's 7 Planets - C

C

Calcos

A Federation penal colony mentioned to be relatively close to Sardos. Six prisoners were brought to Sardos from Calcos aboard a transport ship that Tarrant and Vila teleport over in order to sneak down to Sardos.

Calipheron

Planet where the Liberator was headed before Avon altered course for Terminal. Avon later told the crew to go there if he lost contact with them, and Zen was programmed to automatically take the Liberator there after twelve hours of Avon's teleporting down, unless he returned earlier.

Callisto

Jenna was once "asked" by the criminal organization Terra Nostra to smuggle a shipment of the narcotic shadow from Callisto to Earth. She refused and was set up to be arrested shortly after. In the episode "The Way Back," Jenna mentions doing smuggling runs on the "near worlds" — suggested to be Federation colonies established relatively close to Earth, and thus suggesting that the Callisto she mentions is the moon of Jupiter.

Carthenos

Federation world mentioned as suffering severe climate control problems after the sabotage of Star One. A brief video clip of the world showed palm trees battered by a hurricane-like storm.

Casarus

A possible planet, mentioned by Vila as the site of a "swamp fever" that killed millions.

Caspar

Remote planet used by a gang of pirates called the "Space Rats" as a home base. Among them was a brilliant engineer and Federation defector named Plaxton who developed an advanced space propulsion system that Avon wanted to use for Scorpio.

Cassiona

One of the worlds marked on a star chart of places considered as an option to take Gan for medical treatment when his limiter implant malfunctioned. Although it had sufficient medical facilities it was mentioned to be a Federation stronghold.

Centero

Location of a Federation communications base where Blake steals a cypher machine so that his team can monitor Federation transmissions. During the raid Cally is left behind, and Travis uses coded messages to set a trap for Blake.

Cephlon

A barren planet with slightly heavier gravity than Earth and constantly bathed in radiation which can be deadly after prolonged exposure. The natives of the planet are Neanderthal-like primitives, apparently immune to the effects of the radiation. Avon, Vila and Gan learn that Cephlon was once home to a more advanced civilization that destroyed themselves in an apocalyptic war. They encounter a woman named Meeget, the last of her species, who requests they help activate an ancient colony sleeper ship that was headed to a new world in hopes her ancient people could start again.

Chenga

A planet Vila lands on after the battle of Star One and the abandonment of the Liberator. It appears to be home to two groups of humans – one living in jungle caves who have abandoned technology, while the other "The Hi-Techs" remain more advanced. The Hi-Techs hunt the primitives in order to harvest their organs for spare part surgery. The Hi-Techs were also in space searching for survivors after the Intergalactic War in order to harvest their organs as well.

Cygnus Alpha

A barren, desolate world used as a penal colony by the Federation. It took the London prisoner transport eight months to get there from Earth. Blake and his associates are sent there at the beginning of the series as punishment for their crimes. The penal colony was controlled by a strange cult leader named Vargas who worshipped a pagan god that demanded human sacrifice and absolute devotion. Note: The name could be a switch of Alpha Cygni, also known as the star Deneb, which is approximately 3,200 light years from Earth.

Cynra

Star system shown on a star chart along with Aristo and Exiton on the Liberator flight deck as Blake journeyed to meet Ensor.

Cyntha

Frontier system mentioned by Avon as being threatened by the Federation Pacification Programme.
