The Fifth Doctor visited Gallifrey to tell the Time Lords that Morbius was launching a plan of galactic conquest — a visit complicated slightly in that he was visiting the Gallifrey of his personal past at a time when he was still on the run. He proposed that Morbius be defeated by a military campaign as the best means of undermining Morbius' authority without more desperate measures such as killing Morbius in the past. The Doctor was selected as the only viable candidate with the tactical and species experience capable of bringing together the many military species who could oppose Morbius's army.
