Time Lords possess space travel machines.
Time Lord . Time Lords are so named for their command of time travel technology and their non-linear perception of time . They developed a culture of custodianship and time-related technologies based on this perception which includes strictly controlled space/time travel machines ( known as `` TARDISes '' ) and monitoring devices to travel through time and to prevent time from being subverted or abused -- although actual action was described as rare in practice due to their traditional policy of strict non-interference and neutrality .
