Enemy of My Enemy

Publisher's blurb: Something odd is happening to the citizens of Phlan. Some have inexplicably gone mad and must be restrained, while others have developed strange magical abilities. No one is immune as it has affected young and old, rich and poor, strong and weak. Opinions about the cause are plentiful, but some theories seem more solid than others. A four-hour adventure for 11th - 16th level characters.
