Froyo flees his happy home at Boggy End to escape an invasion. The invader is Celosia Roak, a female halfbit interested in slapping a wedding ring on Froyo's finger and helping him spend all his delicious, unused money. A visit to Eisenfang to see his good friend, Grandkopf the Gray, seems like just the thing. On the way, Froyo discovers that the windows and doors of his coach won't open. Then Lily, a northern Smirkwood tree elf, comes through the roof door and announces that she is the elf he hired for companionship for his journey. This is news to Froyo. Soon, it's clear that Froyo has been kidnapped. Froyo and Lily must plot their escape... The evil Nostril overruns Ember with 100,000 Grimites and marches on Del Mar.

But they are too few. Will the elven rings turn the tide, or will Nostril's new ruling ring control them and turn them against their allies?

Arrowshaft sets out to do the job. Separately, Lededgas and Gimmie leave Del Mar, Del Mar on the same mission. They must sneak into Nostril's camp, kill him, and somehow survive the aftermath.
