Theory:Timeline - Team TARDIS

This page lists appearances of Graham O'Brien in the order in which he experienced them. This timeline is based upon observations of the Doctor Who universe and the events that occur during each of these stories. From these observations we have attempted to build a concise timeline. It is assumed that for each novel, comic, audio or television series, their published, broadcast or numbered order is the order they occur in.

The layout of this timeline is in part based on the observations on Doctor Who - The Complete Adventures, as well as Lance Parkin's AHistory and other sources that allow us to make observations, such as Doctor Who Reviews, and Clive Banks databanks. None of these sources should be used solely as a source or considered a "true" timeline for stories.
