Four more sessions of Castle of Horror:
Session 12 saw the PCs explore the Castle catacombs, be subjected to a curse that teleported them into an underground river, and then forced to fight a bunch of highly surprised Spheres of Madness

Session 13 had the PCs defeat the Spheres and explore the new area they were in, culminating in a fight against a group of pixie ghouls:

Sessions 14 and 15 continued the fight against the pixie ghouls, including a spell slinging leader who damaged a great deal of their equipment. The PCs eventually triumphed and continued exploring the Castle:
