Almost nothing is known about the Doctor's background and past, other than that they had a doctorate in neurology and had extensively researched Oripathy prior to the events of the story.

Currently suffering from amnesia, the Doctor was rescued by Amiya from Chernobog when Talulah led the Reunion insurgence against the Ursus empire.
