The Staff of Fanon is an adventure for most adventure parties and rule systems. It is designed for Hârnmaster, but is sufficiently generic that it can be adapted to all rule systems. The plot is designed so that the GM can adjust the level of danger to match the abilities of his player group.

The adventure involves the players in a quest for an enchanted, elven staff. A mysterious and fearsome otherworld entity has stolen the staff, and placed a cruel enchantment on a manorial village that dooms the settlement to starvation and extinction. Only by retrieving Fanon's Staff can the evil spell be broken, and the village saved.

The Staff of Fanon is a stand alone adventure, but it is also the first of a series of three inter-related modules that build into an epic, interworld adventure.
