Nothing yet, though some good answers along the right track.
Ak4su, I agree about riddles which are so vague that many answers would actually fit the bill just as well as the correct one. Such is not the case with this particular riddle. None of the wrong answers fit "all" the clues with ease, certainly none given so far. As with most of mine, the one correct answer will be clearly obvious in light of other possibles. In my opinion, that is what makes a GOOD riddle. Sure, one can make an effective argument for their guesses, such as Molly Mae did for the Death and the Maiden riddle, but the correct answer is usually the more elegantly simple one (hats off to WOD). That said, any guesses? Good luck.
