"Yes, perhaps this Strahd fell victim to a curse that transformed him into some sort of monster," Nelyna agrees.

As they enter the room with the strange offerings, the wizard can't help but be intrigued. She crosses over to the niche with the mummy figure and examines it more closely.

"Bat guano makes for good fertilizer, there were people who would collect it and sell it to us to place in our fields, made good money too but a crappy job for sure." 

Razi explores the prison, with special attention to the robed skeleton.  “This one wears a robe like those we found upstairs.  Could this be a… turncoat?  Some one who stole from them?  Or perhaps discovered a conscience and earned the ire of the master of this house?”  Investigation: 3

(With that roll, I doubt the struck text would have occurred to Razi.)

Caine looks back at Sleet and his guano comments.

"Crappy job, eh? There's more to you than your letting on, isn't there?" Caine says and nods with a smile.

He catches up with Razi and the robed skeleton.

"Maybe they were short sacrifices? Or they made the sacrifices wear the robes?" Caine suggests.

He checks the are for traps or holes that swarms of creepy, crawly, bitey insects will come out of.

Perception: 5  

If he doesn't find any, he grabs the robe and shakes it to see if anything falls out then goes through all the pockets.

Jim nods his head, "Yeah, I think this might be a cult member. Though why was he shackled here? Perhaps he broke their rules?"

Nelyna comes over to the skeleton with a frown. "What an awful way to die," she remarks. "Strung up here in the dark all alone. They are cruel enough to do this to one of their own; I can't imagine what they will try to do to us." She shudders a bit, thinking of the chanting.

"Oh great, a cursed ring to take with us."

Does the ring have any engravings or clues as to the identity of the wearer?  It's a bit too close to grave robbing for Razi to be interested, but he won't judge anyone else.

"I'll take it, might be able to trade it for some food or information in a pinch."

reaches to grab the ring unless someone stops him...

@All

 Caine looks at the skeleton for a moment longer then does another look around the cells to see if there are any hidden compartments or doorways.

Perception: 4  

Caine shrugs after looking around the cells a little more and turns to double back to the curios room and the other passage way that lead down to some water.

"Everyone ready?" Caine asks. "That pool of water was as far down as the dollhouse showed."

Razi nods.  “Let us follow this course to it’s inevitable conclusion.”

"Agreed, let's see where it takes us."

Caine gets to the passage that lead down to the water. A chill runs up his spine at the sound of the chanting but he presses forward, keeping any eye out for traps, especially pits.

Perception: 9  

Jim will follow behind everyone else as they all head down into the other room. He will look out for any clues that might reveal why there is chanting or why there is water.
