There isn't talk of it. There is blatant plot hooks layed out in the first few minutes of Dark Dawn. Yes this is another reason this game is terrible. I hate to use the standard response, but this is Camelot. They know it is easier to write if you assume there is going to be a sequel, you don't have to resolve anything at all and just have to say enough things until you decide you have made enough dungeons. Plot threads can be dropped and series can stop coming out whenever the money stops.
