Spoilers are strongly policed here.
If this thread's title doesn't specify it's spoilery, don't bring any up.

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[statement unclear]. 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, Doc Oho's Book Reviews, The History of Doctor Who, The Discontinuity Guide, Clive Banks Databank, Whopix, 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.

With aid from the Watcher, the Doctor regenerates from his previous incarnation in the company of Adric, Nyssa and Tegan Jovanka at the Pharos Project after a battle with the Tremas Master.
Set immediately after Logopolis, with the Doctor being helped back to the TARDIS by Nyssa and Tegan as Adric distracts the guards at the Pharos Project, though he ends up being captured by the Master. While the Doctor rests in the TARDIS Zero Room, the Master hijacks the ship and forces it into a collision course with Event One, with the TARDIS crew only escaping by jettisoning parts of the TARDIS, including the Zero Room. Still needing to recuperate, the Doctor instructs Nyssa and Tegan to take him to Castrovalva, though he finds it to be another trap by the Master. Once he fully recovers from the regeneration trauma, the Doctor saves Adric, and the Master is left trapped in Castrovalva as it collapses while the TARDIS crew escape.
Set during Castrovalva: Part 1, when the Doctor is resting in the Zero Room before the Master interferes with the TARDIS navigational systems.
