Fan-made photoshop (see original posting here)
The Doctors quest to find Gallifrey is over.
8.12 'Master and Commander'
The return of the Master and consequently the Time lords. Its believed the Master is now the president and will be played by esteemed British actor Charles Dance.
I thought Charles Dance would make a great Master back in 2009 and just made the above picture as part of my Alternate Whoniverse. I even had Peter Capaldi down as the Thirteenth prior to his reveal as the Twelth Doctor (Thirteenth Incarnation)
It will interesting to see how much of the above comes to fruition...
