I thought this would be an easy one. Some of the riddle's parts were meant differently than you interpretate them, but my point was that you have at least general idea and not just blindly shooting in the dark.
(For eventual interpreters, I'd only correct two important moments in the riddle: the "jealousy" was a hint on Gandalf who received Narya right after his arrival; and the final two lines were not supposed to point to bruta facta as Gil interpreted it
but pointing to Saruman's constant rejecting of mercy offered to him by Gandalf, Galadriel, Frodo etc.)
Enough of this.
Gil-Galad, well done, it's your turn now.
