The year is 1541 in a world much different from ours. Join an intrepid band of inventors, spies and scapegraces in an adventure that puts the hole Schmalkaldic saga in context! In this story that was simply too big for one episode and yet too small for four, the Schmalkaldic League faces off against two factions of renegade geologists: the Neptunians and the Vulcanists, with the fate of Europe hanging in the balance! In part three, Countess von Uexküll, Grimhilda the Psychosomatic Poisoner, and Aldo Krasplasian, Hungary's King of Puppets, are about to be put into a very large, very deep hole by Charles V, the Holy Roman Emperor. But what is the Emperor's connection with the Pope? And who is the shadowy, secret ally of the League posing as Count Crimsyn? And how will they get away from the Giant Pygmy Marmoset of Gordium?
