aye! i do know of that one.

you could attack them, bout 400 or so xp for each kill. as for adverse effects of doing that i don't really know. but if you do attack them save first.

i did attack them on me earlier character and no one said a thing bout it, but, of course i did not finish the game with this character though cuz i started a new one <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />.
