Upon returning to the small town, they run into a friendly merchant who offers them free drinks. Several of the PC’s take him up on his offer and two become inflicted with a strange disease. The PC’s confront the merchant later that day and he is forced to give up the real reason he offered them the drinks. He has been hired to give them the drinks by a certain Red Wizard, but he claims that he had no knowledge of what was inside the drinks.
The PC’s decide to march back to the Red Wizards tower, but before they do his image appears and laughs. The Red Wizard then demands that they go to a small village on the edge of the Moonsea where another Red Wizard (and rival to him) lives and steel a special spell book. If they do as he asks, he will give them the antidote. He claims that the poison is fatal after 5 days, so they better hurry.
The PC’s reluctantly agree and leave in haste. They travel for two days before coming to the wizard’s tower. Ginger The Snap finds a secrete entrance and they slip in unnoticed. On the walls, the bard Burt the Bastard reads some runes, which immediately explode. He takes some damage, and the PC’s learn that they should not read the writings on the wall. They make it inside, and Ginger The Snap finds another secrete door which leads into a storage room which has a number of monk weapons-some of which are magical. The PC’s help themselves to the weapons and continue down the hall into the main chamber. There they find a monk. Burt the Bastard greats the suspicious monk and manages to charm him. The monk is now helpful and takes the PC’s up stairs to where the book is being held.
The PC’s decide that it would be better to make a fake duplicate of the book to give to the Red Wizard, then the real one. They spend two days making the forgery, then travel back East to deliver it.
The PC’s are met along the rode by the Red Wizard, who demands the book. The PC’s demand the antidote first, and eventually they come to an agreement and each gets what the other wants (except that the Red Wizard got a forgery). The Red Wizard then raises a number of dead that the PC’s passed along the road to attack the PC’s just for fun. The PC’s defeat the undead and return back to the Wizard’s Tower.
When just outside, they saw that the town in front of the tower was burned and pillaged, and the tower was under attack by the forces of a powerful wizard named Sammaster. It turns out that Sammaster is also interested in the same book. The PC’s rush to the tower, defeat some the Sammaster’s minions, save a monk that was being interrogated, and fight their way upstairs to Sammaster, but are too late. Sammaster has already found the book and teleports away.
