The short version: what are five riddles whose answer is "the moon"?
Longer:
I'm preparing to run the D&D module "White Plume Mountain". At one point in that Adventure there's an encounter with a sphinx who asks each character a riddle. Unbeknownst to the party, the answer ("moon") is also the password to disarm a nearby magical trap, so that the trap does not attack that character. So the sphinx needs to get each character to say the word "moon" before they continue.
Using the scenario as written, the sphinx would ask this riddle to each character in turn:
Round she is, yet flat as a board, Altar of the Lupine Lords, Jewel on black velvet, pearl in the sea, Unchanged but e'erchanging, eternally.
But this is silly. What self-respecting sphinx would ask the same riddle five times in a row?
So: what are five riddles (counting the above riddle) whose answer is "moon"? It's okay if some of the riddles are a bit lame or awkward. It's better if the riddles avoid anachronisms since this is a fantasy setting.
