Fanaticism can be just as dangerous as fire. Spreading like fire, it could spark rebellion and could lead towards violence. As a way to curb devotion to the abstract, king Hareth of Garilroot asked his Mages to come up with a solution for those too invested in an ideal.
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.)
