Time Lord

a Time Lord is a special sort of Cosmic Being that is responsible for maintaining the proper flow and processes of time, which means they do not age as we other beings do. They may employ time travel means, or they may take mass transit, but they are noble professionals who avoid time-fuckery or other paradoxes in their efforts to keep the Omniverse (and themselves) from eventually dying, but they will not succeed because it has already happened.

If you are very unlucky one may abduct you to be their plucky ward sidekick for a number of increasingly horrifying and deadly adventures
