Federation universe

Federation Universe is a parallel universe where Earth is part of the United Federation of Planets meta-government (IDW: Assimilation²).

History
This universe was joined together with the Doctor's universe by the Cybermen so that they could form an alliance with the Borg, a simiar cybernetic race native to this universe. The only known people who were aware of the two universes having been merged were the Eleventh Doctor and Guinan.

Overview

 * While the planet Earth and Humans exist in both universes, some of the races native to the Federation Universe are not known to exist in the Doctor's universe, including the Borg, Klingons and Deltans.
