The Desert of Despair was a craterous region of Skaro with strange magentic properties. It bordered the Dalek City's desert and the Islands of Mists, with the Bore Hole also being at the Desert's edge.
Space travellers often landed in the Desert and remained there lost for months due to their navigation systems being impacted by the strange magnetism. (COMIC: The Dalek Trap [+]Loading...["The Dalek Trap (comic story)"])
