A haunting remnant of the infernal realm, caught and exiled to suffer for eternity in the swamps of the mortal plane. Now it toys with mortals; luring them from their paths into it's light. Once in the boundaries of it's aura, the FlickerWikk will feed.
A Remake of the Will'o'the'Wisp/Jack'o'Lantern
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.)
