Flames of the Falcon (1990)

From the back cover:

"Assaults on the City of Greyhawk by a vengeful cleric of Iuz have terrified citizens and caused an exodus of residents. If this cleric is allowed to continue her evil plans, Greyhawk will become little more than a ghost town, ripe for the picking by the evil cleric's followers.

Volunteers are needed to hunt down the cleric and her cult before she unleashes her undead minions into the streets of Greyhawk - and it is only a matter of time before she claims the city as her own!

Flames of the Falcon is the third of a three-part series of adventures for the ADVANCED DUNGEONS & DRAGONS 2nd Edition role-playing game. The trilogy began with Falcon's Revenge and Falconmaster - now the thrilling adventure concludes in this module.

This adventure can also be played as a stand-alone module. Set in the famed City of Greyhawk, Flames of the Falcon is designed for five to seven characters of levels 5 to 7."
