The
Exo-Space Time Continuum. A neighboring
universe featured in
Doctor Who. It is very small and access from our universe is only possible through CVEs, believed natural until it was revealed the the people of
Logopolis created them artifically to let
entropy leak out of our
universe and delay its inevitable
heat death.
E-space is home to
the Great Vampire where it fled after the war with the
Time Lords. It is served by
the Three Who Rule.
E-space is also the home of
Adric, companion to the
Doctor. It was at the border to E-Space that
Romana and
K9 bid farewell to the
Doctor and left the
TARDIS.
