Summary
The Doctor travels to Arthur's World to aid in his birth; the Doctor used the alias Merlin but discovered that he was the second person at the time to use the name Merlin. The other Merlin was another renegade Time Lord who had given Arthur and his kingdom advanced technology and prompted Morgaine to seek an alliance with them.
