Good question because -- I just ran into an issue that brought it to mind. smile

Place: north of the shadow lord on Nameless Isle.
Who: Black Ring Camp (with dreamers)
Why: I wanted to take advantage of terrain rather be in a kill zone so I lured them back to the shadow area where three of my crew were placed.
What: Several times, the shadow prince and his minions agroed on me despite not using area weapons anywhere within the ruins. Once because a dual wand user had one of his wand shots hit an invisible minion; the other times, I have no clue why. We were even on good terms as I agreed to kill the mother tree (nobody told me it would leak above ground and kill everyone which I assume means Alexander preventing me from completing the sallow man task. Oh well, live and learn.
