The Rock of Tormentos
The four companions are summoned by Philip du Paix, who describes to them Isla Tormentos and the problems it is causing the Montaigne blockade. He then tells them that a Vodacce captain has acquired landing codes on the rock - the series of signal flags needed to keep the ship from being fired upon - and thus he would like to smuggle the heroes onto the island. There, they are to break into Punta Grande, the main fortress, and take a blooded mirror out of a snuffbox, at which point Lucien du Lac will bring through an Eisen mercenary captain named Holzt and a dozen picked men to silence the guns. With the guns silenced, Philip explains, the Montaigne fleet will attack and take the island.
Of course, there's a wrinkle: the Vodacce captain is none other than Captain Crispino, the companions' old nemesis. Some unhappiness over this aside, however, the heroes board Crispino's Il Falco and set sail for Tormentos.
