Claim: Time Lords' have space/time travel machines.
Evidence: They developed a culture of custodianship and time-related technologies based on this perception which includes strictly controlled space/time travel machines -LRB- known as `` TARDISes '' -RRB- 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.
