List of Blake's 7 Planets - A

A

Agravo

Planet along with Mercon II where the valuable Feldon crystal was mined. Agravo's mining facilities were destroyed in a series of explosions caused by lack of safety concerns and over-mining. Avon mentions the facility would have been destroyed eventually as the Feldon mines were running dry and the Federation would have wanted to "cover up" the illegal operation.

Albion

A frigid planet in the midst of an ice age, with a population of 6 million – all living near the equator which is the only habitable region. Federation officer, Space Major Provine, was tracked here by Blake and his crew. Provine was one of the individuals who supposedly knew details regarding the location of Star One. The inhabitants were resisting Federation occupation when Blake arrived. During a battle, Provine slips past Blake disguised as a resistance soldier and activates a radiation bomb that will kill everyone on the planet, yet leave the infrastructure intact. Avon and a former associate, Del Grant, track down the bomb which was hidden in a bunker at one of the planet's poles to deactivate it. Note: The name "Albion" is the oldest known name for Great Britain.

Altern V

A planet in a star system heavily patrolled by the Federation, although the reason for this was never discussed. The crew of Scorpio try to go there to get an ore that will make fuel crystals, and tried to sneak into the system by shadowing an asteroid, but instead they collided with it.

Aristo

Retreat world for the hermit genius Ensor and visited by Blake and Cally. The Orac computer was hidden on Aristo with Ensor in his underground laboratory. From space, the planet appeared to be primarily covered by water with only a few island chains providing dry land. Lizard-like biped creatures lurked in the tunnel system that led to Ensor's lab.

Atlay

Location of a political meeting venue for Federation governors where the defectors Ven Glynd, and LeGrand were to present evidence of Federation atrocities. Upon arrival, they are captured by Servalan and executed as traitors. Blake discovers Travis had disguised himself as Shevon, one of resistance leaders.

Auron

Homeworld of Cally and her telepathic, cloned race, the Auronar. The Auronar were highly advanced, and ahead technologically in many areas than the Federation. It was mentioned many times that Auronar weren't fully human and possibly the result of genetic manipulation. The Liberator crew go to Auron to stop Servalan who unleashes a deadly virus upon the Auronar in order to capture their cloning facilities.

Auros

Travis was suspended from duty for ordering the massacre of unarmed civilians on Auros. Later Travis is tried for the massacre of 1,417 people on the planet Zircaster suggesting that two different massacres took place, or that Auros and Zircaster are possibly the same planet.

Arcos

Planet where Del Grant led a revolt against the Federation at some point before his activities on Albion.
