So I'm writing an adventure for Swords and Wizardry complete and could use some advice/thoughts from the community. As the adventure starts, the pc's are basically chased through a maze by a group of weird fast-moving undead (they don't know how they got there) along with a group of Orcs. They get sort of herded into this big manor house. When they enter the great hall, there's a banquet going on. All the folks attending the banquet are ghosts, kind of. I was them to be able to switch between ethereal and non-ethereal. I haven't decided what I want to actually be going on in the banquet. I do want the ghosts to respond to the PC's, interact with them, maybe even fight a little bit. It's for beginning characters, so they players won't have magic weapons. If anyone has any suggestions, I'd be more than grateful.
