I was looking through the forums (the new one only) and could'nt find anything about the orbs, I already know where the white one is (talk to the green shadowling, ask her how she like the city, then say except what, and then go in the basement and kill the spiders, then ask for the antique) but I don't remember where the others are. i remember seeing a topic about them before, but that was most likely in the old forums, and it's been some time since I've played this game.
