I'm also curious, and I hope the next update will come:
I - one bow or two strong bows (with banishment)
II - something related to the head of the seventh house in which Kardagis comments.
III - that Baron, I do not remember, there new garand, that you ask to schedule a meeting with him but the game says he would not have to.
IV - the old and initial mine of lannegar, this one is old, too curious! and the other npcs you quoted. Finally, I would like a darker place in EK, with monsters between level 18-23. I do not want icemist sewers to be the best place to do xp in the game and that is also the "reasonably difficult" place next to the ark. I want more, more challenge and difficulty, hehe
edit: I do not want EK to be finalized now, there are still a few missing details, more missing and I love this game, and how!
