The Will-o'-the-Wisp, sometimes called Will-o'-Wisp, are ghostly lights occasionally seen in twilight over bogs, swamps and marshes. They are said to look like flickering lamps, and recede if approached. There is much folklore that exists around this phenomenon. Some rumors state that goblins, gremlins or even demons carry these ghostly lights, and that they will lead unsuspecting travelers from their path, never to be seen again . . .
