“ 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.)”
“ No undead provokes more sympathy than a Motherthing.
These are the frightening remains of mothers who lost a child to violence. These undead gather children that are encountered alone and "mother" them ". They fiercely protect their "children"”
