Wendy:
Listen closely, for this pertains to Dr. Chaos. From time to time, he comes here.
If you attempt to speak with him, though, he will treat you as an enemy and dispatch a Gigantic Chaos Golem to rend the flesh from your bones.
If you can defeat him here, it will certainly keep him from causing any trouble for a while.
As Atlanta said, it should not be a difficult task provided that excellent adventurers such as yourselves are able to work together.
Ask about the Horrifying Golem Army.
