Devil's Hump

From TARDIS Index File, the free Doctor Who reference.

Devil's Hump was the name given to a mound in a field outside of Devil's End. Its significance only became clear in the 1970s when Professor Horner uncovered the Devil's Hump as part of a television show for BBC3. The Devil's Hump was (when examined by the Doctor) the remains of a Dæmon ship; Azal's in particular. (DW: The Dæmons)
