Godfrey Porter's universe

Godfrey Porter's universe was a reality where the Doctor and his adventures existed as works of fiction, (PROSE: The Thief of Sherwood) similar to the various other meta-fiction universes encountered by the Doctor himself. (COMIC: TV Action!, The Girl Who Loved Doctor Who, PROSE: All Our Christmases)

Godfrey Porter was one of many writers to pen an episode of the Doctor Who TV series, namely The Outlaws, a story corresponding to the First Doctor, Ian Chesterton, Barbara Wright and Susan Foreman's encounter with Robin Hood, (PROSE: The Thief of Sherwood) which another account confirmed to have happened in the Doctor's own reality. (PROSE: That Time I Nearly Destroyed the World Whilst Looking for a Dress)

Behind the scenes

 * Godfrey Porter's universe, that of the frame story of The Thief of Sherwood, was explicitly confirmed in 2020 on Twitter by Jonathan Morris to be meant to be read as a separate universe from the Doctor's own, though one where the Doctor could theoretically travel.
