Regarding the disclaimer, if a rooster lays an egg, I'm going to be exceedingly surprised (as, I imagine, would he). I like the prophecies and they work well. 'Twould appear that Lucy is the White Witch and I'd hazard a guess that Ron is the Traitor; I'm not sure, yet, who's the Jester (Neville, perhaps? But it doesn't seem to suit what we know of him).
Author's response
Maybe...The Jester will be a canon character, used in a relatively canon way, perhaps with a few embellishments. The Traitor will be a canon character handled in a slightly non-canon way. I give a big clue about the identities of the Jester and the Traitor, but so far no one has picked up on them. I don't plan on revealing who for a while, unfortunately for you.
