Morbius war

The "Morbius war" was the interplanetary war waged between the Fifth Doctor's inter-species Alliance and the Gaztak mercenary armies of Morbius, in an effort to prevent the exiled Renegade Time Lord from conquering the galaxy. The war was raged across over a dozen planets and resulted in the capture, trial, and execution of Morbius. (PROSE: Warmonger)
