The heroes and their circus arrive in Willowside, a swamp community in dire need of diversion from the relentless expansion of the blighted land known as the Welt. Willowside soon experiences a problem of a different sort, as dinosaur-riding xulgaths blockade the town. The heroes mount a defense of the village and learn what has brought the xulgaths to this isolated settlement. When the heroes break the siege, they learn that the xulgaths follow a monstrous ex-slave and have forsaken their directive to assault a nearby aeon tower. The tower's current occupants know more, and put the heroes on the path to reach the fifth and final aeon orb.
