CWK weapons mystery, where is the end of storyline?

i dont feel cwk is over too, but if is i am really disappointed with cwk 2, we did so many quests to get mark of heroism /map and the story about the keep used to be so exciting, but the expansion is just a PQ with no quests (well 1 quest), no story, some "hints" of something, and a bunch of random items (the bonus stage). kinda sad
