The Companion Chronicles

The Companion Chronicles is a series currently produced by Big Finish Productions. The plays are stories recounted by one of the Doctor's companions (or one of his other friends) with one other actor in a supporting role (exceptions being The Mahogany Murderers which featured three actors and Stealers from Saiph which featured actress Mary Tamm performing all the roles).

Concept
Originally, the concept was to produce talking books featuring the companions of incarnations of the Doctor who were unavailable to take part in the main audio range (due either to death or refusal). However, the range is now expanding featuring characters who are not strictly companions and companions of doctors who are featured in the main range.

Continuity
A few of the plays tie in to other plays in the Big Finish Doctor Who range. The Darkening Eye is a prequel to The Death Collectors, and in The Prisoner's Dilemma, Ace meets Zara, Amy's sister and a fellow tracer.''

A number of the plays reveal the lives of the Doctor's companions after leaving him. It is revealed that Vicki remained with Troilus and had a large family, all the while still feeling like an outsider. According to the plays, Leela survived the Last Great Time War, but lost the anti-aging protection given to her by the Time Lords. Susan Foreman stayed with David Campbell, and Victoria settled down to raise a family.

Home Truths and The Drowned World, taking place between episodes of Sara Kingdom's first and only televised story, The Daleks' Master Plan, reveal for the first time in canon that she had other adventures as one of the Doctor's companions before her death at the end of that story. The latter story, however, begins after her death, and depicts her as a ghostly apparition.

List of Plays
The Mists of Time, released in August 2009, was a download-only release made available to readers of Doctor Who Magazine #411 for a limited time. It is not known if a physical release will occur later, or if the story is included in the overall numbering for the series.
