Arriving at the castle's gatehouse at the top of a bluff, they try to force their way through the sorcerous fog that repels them. As a result everyone is turned into a frog and teleported away. Twenty-four hours pass and they return to their normal forms, but another day of their already limited time is wasted in the process.
Back at the castle, they rappel down into the ravine. They explore some cave mouths and fight off goblins, snakes and bats. Finally, they are ready to enter into the caverns that penetrate the plateau upon which the castle rests.
