She betrayed a controlling, manipulative spider god, is she desperate because she was thrown out of DE society? Did she MEET the absolute and was converted? Does she really hate teiflings because one stole her lunch money?
We never find out anything about this, even when you do everything right and sidestep the dozens of forks in the road where she betrays you. Not to mention that you have no incentive to side with her to begin with / the discrepancy with the information we get from the Nautiloid. I might make a separate thread about that last bit later as I really want to know how much of the EA content was written without the intro being finished, none of the Absolute's followers should be this antagonistic when faced with a fact the player finds out about in the opening cinematic.
