A Second Adventure in Basthinia After the King of the Yellow River is defeated, the children from Covendale are finally ready to return home. Upon approaching Nova Marmoxa, however, they witness a strange sight on the horizon - a thick green cloud is wrapped around the sleepy Laubendan city. Sage believes this cloud has something to do with a period of Basthinian history called the Bronze Age, a time when an island people ruled the waves, when a cult of mages kept watch over the continent, and when six heroes battled an invasion of monsters and a treacherous sorcerer. And soon enough this green cloud explodes into life, pursuing the children and their companions through sodden marshlands, over crocodile-infested waters, across an eerie country of hills and valleys, and down into a forgotten city, where Sage at last comes up with a plan to halt the progress of their new enemy.
