Mission of the Viyrans was a one-part story comprising part of the one hundred and second release in Big Finish's monthly range. It was written by Nicholas Briggs and featured Peter Davison as the Fifth Doctor and Nicola Bryant as Peri Brown.
Unlike other one-part stories, it is not connected to the main story with which it was released nor does it have the same cast as the relevant story, given that this story does not feature Erimem, played by Caroline Morris and isn't written by the same person. Nevertheless, it continued a virus strain story arc which concluded with Patient Zero.
Publisher's summary Edit

- The original title of this story was Patient Zero. It had to be changed because of a similar title in Torchwood.
- Peri recalls her imaginary stepson Kyle (AUDIO: The Mind's Eye), meeting Dracula in Ungro-Wallachia in June 1462 (AUDIO: Son of the Dragon) and Erimem's departure from the TARDIS on Peladon in the 41st century (AUDIO: The Bride of Peladon).
