yeah...It could always heave been a case of a misinterpretation of the initial message being taken as gospel and passed down to the later generations. I was thinking that the Cup would only be brought out at formal occasions and the only one that would be allowed to handle it (by tradition as opposed to actuality) would be the King. The current Dynasty has been in power so long that they have forgotten that they are NOT the first to be in possession of the cup.
That is a very good point. Arrogance of kings and all. It would also cover the "why can just about anyone use the cup" question


I was thinking that (in my version) that the first bunch of names on the rod would be in a language unreadable without magic, and might even contain names that are definitely not of human origin.
Another very cool thing ( I can see maybe elves or Dwarves one of the long-lived races or iilithids or dragons even)
