After waking up groggily in the middle of a floating wizard's tower, the players must find some way to escape before being slain by the beast that stalks them. Time is ticking and the cat is always watching . . .
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.)
