The Traveling Wizard is a man of minor repute. He has made great impacts on a few places and people. Those that know him, know him to be powerful. However, most do not know him, for he travels the world. He seeks experience and knowledge, craves adventure. The journeys of the Traveling Wizard seem to never end.
A planet (or city, valley ect) where those who enter witness protection can escape old age and death itself, so they can live for centuries without aging-provided they maintain their cover perfectly. If they are outed by anyone or ever utter their true name, they age the number of years they have not aged since the day they entered witness protection (which might mean that they age centuries in seconds and crumble into dust and bone.)
