Mission to Magnus (audio story)

 was the audio adaptation of the unproduced television serial of the same name. A part of Big Finish's The Lost Stories range, it was written by Philip Martin, the writer who originally submitted it to the television production team in the mid-1980s, and featured the main actors who would likely have starred in it had it been made as a part of its originally intended season.

Publisher's summary
The Doctor and Peri face enemies at every turn on the planet Magnus. There's the Time Lord bully Anzor, who made the Doctor's life hell during his time at the Academy. There's also Rana Zandusia, the matriarchal ruler of the planet, who seeks to prise the secret of time travel from these alien visitors. Also on Magnus is the slug-like Sil, still bitter from his defeat on the planet Varos and seeking to make his fortune from the most potentially destructive ends. And, deep within the planet, there is something else. Another old enemy of the Doctor's. And the future is looking decidedly colder...
