In one of the infinite parallel universes of "possible space", (COMIC: Fire and Brimstone) the Doctor's father Ulysses left him a final message at time-space coordinates that turned out to correspond to the Cairo Museum on 23 November 1994. Searching the Museum, the Doctor found a sarcophagus purportedly housing the remains of the pharaoh Cheops, but which turned out to be empty save for a message from Ulysses. Nevertheless, the Museum also contained several actual mummies. (PROSE: The Chronicles of Doctor Who?)
