Rassilon was, alongside Omega and the Other, one of the founders of Time Lord civilisation and widely regarded as the single greatest figure of Gallifreyan history. He was generally considered the first Time Lord, though some believed that distinction belonged to his compatriot Omega. In his own time, Rassilon was chiefly an engineer and architect but once he had left his mark, most of Time Lord society hailed him as a hero. Other Time Lords contended that Rassilon was a corrupt megalomaniac who tried to murder his friend Omega and stole his invention to build Time Lord society. During the Last Great Time War, he returned to lead the Time Lords to battle the Daleks, and tried to find ways to break the Time lock and escape the war.
