First door closing, I read as trying to help the gnome kill the evil invoker. Kosher.
second door closing, I read as trying to help a lightwalker kill an outlander who routinely attacks fortress members.
I don't see anything wrong with either of these.
Of course. Having seen said fortress member buddy around with outlanders, I am willing to bet that while the player/char can make the above argument, I'm more convinced the ooc thought processes were "help the outlander kill the oppressor tribunals"
