The Wyvernspur family's powerful heirloom has been stolen, and the grand wizard and patriarch Drone Wyvernspur is the first to fall to the ancient item's curse. The family fool, Giogi, is left to find it, but even recovering the spur cannot guarantee his clan's safety.

Fortunately, the famous halfling bard Olive Ruskettle and a mysterious and talented mage named Cat are determined to help. But when betrayal and enchantment threaten Giogi's progress, he must invoke the spur's awesome might... or become its next victim!"
