The king's wizard summons the Doctor and his TARDIS via mental control. The wizard reveals to the Doctor the heart of the inner sanctum, a colossal fission reactor called the Dragon, which the Neutron Knights intend to possess.

As the wizard and the king's forces take refuge in the TARDIS, the king stays behind to face off against Catavolcus. The Doctor is stunned to discover that the king and wizard are Arthur and Merlin. Catavolcus slays King Arthur and the TARDIS dematerialises before the Dragon erupts, destroying the fortress, Catavolcus, and Neutron Knights. The Doctor awakens outside the now unoccupied TARDIS in a wooded area, and muses at what he had experienced... perhaps a dream, or a time-loop when past and future merge? Back in the TARDIS, a shadowy image of Merlin appears and tells the Time Lord that they will meet again."@en . "Fourth Doctor"@en . "Earth, the far future"@en . .
