your game is probably glitched and your screwed on that quest my friend. It's not that important, all you get is some extra good points from morgana and a very nice robe(for Morgana only). but it lowers her will check so I would'nt get it. ( "will" makes up most of magic properties and what not,also reduces magic damage so you don't want to make her weaker even if it raises some of her other talents by a small margin) The quest isn't worth it. Just give morgana some nice items to improve her liking of you and it's basicly the same results.
