Ever wanted to add a legendary artifact to your campaign, but you were worried about PC’s getting their hands on it?
Or you put the Legendary item in your game and the PC’s already managed to get it?
What to do, and how to fix it.
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.)
