One other thing about Karlach - I haven't played Shadowheart's storyline yet, but the other four (Gale, Wyll, Astarion, Lae'zel) all have a common theme, which ties into one of the game's overall themes: power and its price. But for the others this is a choice, a chance at great power, which they can take if they accept the potential consequences. But Karlach is just... a victim. Where's the big moment of choice for Karlach? Where's her struggle with temptation? I feel like something important is missing here.
