"Hunter shine your light in the room. Maybe the light will harm him. I think he is proving himself to be a little bit off. Killing his own sister is proof of that." Drethen walks up to Ardo with sword and shield at the ready. "Maybe a nice light spell on that desk will make things interesting."
Hunter shines his light all over hoping to spot some smoke emanating from the invisible Charles unless he teleported to another part of the house.
Ardo casts his silence spell on the coin and tosses it towards Charles desk at the same time that Hunter shines his lantern in the same direction. With all of your focus on the desk, you almost miss the fact that the door to the south just closed.
Before you can react and reach the door yourselves, you hear another feint sound of another door closing in the room beyond. When you open the door you see a number of apparently empty clerical robes dancing a bizarre, repetitive dance around a circle painted on the floor in amber-colored paint.
What is even more odd, is that you do not see any other doors leading out of this room.
Out of Character: : I'll let Ardo reconsider if he still wants to summon Ralph.

Hunter takes a well aimed shot at one of the robbed dancers to see what happens.
The books in this library seem to be centered around religion and philosophy. The topics range from good to evil, law to chaos, and every existential question that you can think of. None appear to be of particular interest.
Hunter fires an arrow through one of the robes. It doesn't seem to notice as it continues to dance around the circle, now with a noticeable hole in the cloth of the robe.
Hunter looks back to see who noticed and says… "That could be a portal… anyone want to go to the centre of that circle?" Hunter takes Charle's sister sword and examines it. He also searches the place looking behind books, through the books, checking for secret passages, etc.
