Main Range

The Main Range, previously called monthly range was a Doctor Who audio series produced by Big Finish Productions. It featured stories from the Fifth, Sixth and Seventh Doctors. For a period of time, it also featured the Eighth Doctor, but he later went to his own series of stories, beginning with Eighth Doctor Adventures.

Stories in this range were tipically narratively independent from each other, though sometimes Big Finish would make stories part of trilogies (or tie-in to other series, such as Dalek Empire and Cyberman).

The series began with The Sirens of Time, a multi-Doctor story featuring the Fifth, Sixth and Seventh Doctors. Following this, Big Finish would produce stories with all the Doctor's television companions from their eras, as well as introducing some original companions for their audios.

After almost two years, Storm Warning, the first story featuring the Eigth Doctor was released in the Main Range, also introducing Charlotte Pollard, who would later join the Sixth Doctor at the end of The Girl Who Never Was, and, later, into her own series.

The Main Range also introduced Abby and Zara, two tracers in human form. Abby helped the Fifth Doctor reassemble the Key to Time. Later, Abby and Zara gained their own spinn-off, Graceless.

Vienna Salvatori was also introduced in this range and later given her own series, although it is not considered a valid source on this series.

Other companions which were introduced in this range include Evelyn Smythe, Flip Jackson, Constance Clarke, Hex, Elizabeth Klein, Sally Morgan, Lysandra Aristedes, Will Arrowsmith and C'rizz.

The Main Range also saw the appearance of Frobisher and Thomas Brewster, companions introduced in Doctor Who Magazine comic stories, as well as Bernice Summerfield, who was first appeared in Virgin New Adventures novels and Fitz Kreiner, who was introduced in the BBC Eighth Doctor Adventures.
