Twelfth Cyber Legion

The Twelfth Cyber Legion was a Cyberman fleet that monitored their local galactic quadrant. It was positioned twenty thousand light years away from Demon's Run when part of the fleet was destroyed by the Eleventh Doctor, just to make a point to the Church's Anglican Regiment. Rory Williams also arrived on a Cyber Ship and gained the location of Demons Run from the Cybermen. (DW: A Good Man Goes to War)
