I agree with you, Darkmatter, but I also see Veridis' point. When there is a large amount of power and commotion going down. Creatures are going to come poking around. Orcs and goblins to pillage the power that was there, trolls possibly looking for gold and a hearty meal. Etcetera. It doesn't have to be a giant battle. But it would make sense a pack of some sort would poke their nose in on the commotion and try to take advantage of the jostled band of hero's. But that is only my opinion.
