Theory:Timeline - Fifth Doctor

This page lists appearances of the Fifth Doctor in the order in which he experienced them. This timeline is based on observations of the Doctor Who universe and the events in each of these stories. From these observations we have attempted to build a concise timeline. It is assumed, much like their TV story counterparts, that each novel or audio series their published/numbered order is the order they occur in. There are also many gaps between stories.

The layout of this timeline is based in part on the observations on Doctor Who Reference Guide and Doctor Who - The Complete Adventures, Lance Parkin's AHistory and other sources that allow us to make observations, such as DocOhoReviews, The History of Doctor Who, The Discontinuity Guide, Clive Banks Databank, the Big Finish forum, The Whoniverse and The Divergent Universe forum. None of these sources should be used solely as a source or considered a "true" timeline for stories.

Companions
Stories with Adric must take place before TV: Earthshock, while any story with Nyssa and Tegan Jovanka must take place before TV: Time-Flight, after TV: Arc of Infinity, before TV: Terminus, or after AUDIO: Cobwebs.

Any story with just Nyssa must be between TV: Time-Flight and TV: Arc of Infinity. Any story with Tegan and Turlough must take place between TV: Mawdryn Undead and TV: Resurrection of the Daleks. Any story with just Turlough must take place between TV: Resurrection of the Daleks and before TV: Planet of Fire, with any story with Peri Brown also occurring after Planet of Fire.

Any story where the Doctor is travelling alone can be placed between Autumn and Renaissance of the Daleks, And You Will Obey Me and The King of Terror, and The Veiled Leopard and Son of the Dragon.
