Arminna Xun'sohna:
In Arminna's mind, the action crossed a line. As a priestess of Eilistraee, her job is to work on improving the reputation of good drow, and this work in direct counter to that. Furthermore, she feels that this action is more in line with a follower of the Spider Queen than the Dark Maiden.
I certainly respect the opinion and have no interest in trying to change Arminna's mind on the issue. That said, I'm just curious. If the goal is to improve our reputation with the dwarves, then why help take down a dwarven patrol?
From the mindset of being a drow with little actual knowledge of the dwarven enemy, Meeka thinks this is rather tame when stacked against the atrocities of war of which she has learned. Of course, she only knows of dwarves by reputation (aside from our adventure) and has no concept of just how egregious the dwarves would view the shaving.
