A One-Round Living Greyhawk Bissel Regional Adventure
From the introduction:
The city of Pellak is the current heart of Bissel, filled to the brim with the most important and influential people in the country. Perhaps this is why people are so upset about the recent rash of madness and feeblemindedness. Is this a strange magical contagion or something worse? In any case you will need your wits as well as your sword to get to the bottom of this dilemma. Just be careful not to get too involved.
A Bissel regional adventure for [character levels] 2-12.
