First time A2CS player here. I felt that the vahnatai's land is not interesting and optional .The game gives no clear indicator whether i should clear out vahnatai's land or go back to avernum first. And monster there was quite stronger than what i can handle when i got down there for the first time, so, i worked all the way to pyrog before going to any other place in their land ( i thought that they'd be friendlier if i've returned one of the crystal souls, too ) . So, did i miss something important or interesting?
I just feel like i missed something since it's sooo long into the game before getting the first crystal soul
