Wilderness Years

The "temporal Wilderness Years" were a period in the history of the Third Universe. The Auction, (PROSE: Resurrection of the Author) an event in the War in Heaven, (PROSE: Going Once, Going Twice) occurred during this period. According to the Retconning Crocodiles, it was characterised by "endless time-warmongering", creating a lot of "flotsam and jetsam of history" and involving much warfare and retconning.

Behind the scenes

The suggestion in Resurrection of the Author is that the term of "Wilderness Years" covers the span of meta-time including the War in Heaven and Last Great Time War. This is a metafictional joke, as, in the real world, "the Wilderness Years" is a term often used to refer to the period between the cancellation of the "classic" series of televised Doctor Who and its revival by Russell T Davies; the War in Heaven was a product of the real-world Wilderness Years and the Time War was created to "slot" in the narrative in-between the last televised appearance of the Doctor on television in the classic series — in the form of the newly-regenerated Eighth Doctor — and the introduction of the Ninth Doctor.
