“Thank you” he says to Halyqwyn. He whispers a small prayer, and the remaining wounds on his body instantly heal themselves. “I am back to full strength now, and I have a bit of healing left in case of, well, an emergency.”

Davis will inspect the carving and the eye, curious if the eyeball is a key or something.

Investigation: 10

It looks like the desiccated eyeball you carry around will fit in the divot...

Vanizi watches as Davis inspects the skull. If he mentions the eyeball perhaps fitting, she checks her pockets which don't appear to hold the eyeball. "Didn't you have that, Halyqwyn?" 

"Ooh!  I do, here." And Haly pulls out the eyeball and gives it to Davis.  

“Thanks! Ok, here goes nothing, you may want to stand to the side, no idea what’s about to happen” he says, then he places the eye in the empty socket.

Sleight of Hand: 15

When Davis places the eyeball in the divot of the grinning skull, the eyeball pulses with sickly green light and the double door swings open to reveal a staircase leading further down and south! 

"Down we go? If so, everyone through the door, then I'll grab the eye and follow, in case we need it still. Does that work?" the halfling says, fully in his element, not thinking of the tragedies that got him to this point.

"Yep!" Vanizi agrees. "Seems down is the way the cultist would have gone. So we go that way too." 

Removing the eyeball causes the stone door to swing shut after a minute. Luckily, there is a stone pedal on this side of the door that opens it back up! The bottom of the stairway opens into a 20' wide and 35' long sanctuary with a vaulted ceiling. Stone pews are arranged in orderly rows. Black candles burning green flames occupy niches along the walls. Atop a pulpit at the far end of the hall stands a jagged sculpture of an emaciated hand with one eyeball in its palm. There are passages leading east and west about 25' in. (Map)

DC12 Religion: 

Katarina's fur stands on end as she recognizes the sculpture... (Religion: 13).

"The symbol of the lich-god..." she whispers, eyeing the sculpture warily.

(Vanizi Religion: 5)

"Lich-god?" Vanizi says, not knowing what that even is. "Doesn't sound good." She walks past the pews, first to the east to get a look at that path. Then she moves to look at the path west. (Perception for each:  15, 3)

Both passages go straight for about 25' and then open into a chamber. All is quiet...so far =D

Religion: 14

"Yeah.. lich-god indeed.  Vecna, to be precise.  A powerful lich and god of secrets known and feared on many worlds, why would there be a shrine to him here??"  Haly shudders involuntarily as she watches Vanizi walk the pews.  

Trying to be quiet as she doesn't know what's down the two hallways, Haly slowly approaches the altar, looking for traps as she does.

Investigation  11

“Would you like this back?” Davis offers ‘the eye’ back to Halyqwyn, unable to suppress a smirk at the absurdity of the gift.

“Vecna” he mutters under his breath as he recognizes the symbols. Religion: 19

He will move to the pulpit and investigate the sculpture: Investigation: 5 but something about this room, reminds him of a church and his wedding day, his mind begins to wander, unable to focus on anything for a moment …

Neither Haly nor Davis discover anything in their investigations...

"Shall we just move on?" Vanizi asks as nobody seems to find anything. "To the west?" she suggestions, mainly because that was the passage she was standing closest to. 

Davis nods at Vanizi, “To the west then” and he will head down the west corridor.

Keeping an eye out: 17

(updated map) The passage west ends in a 25'x20' room with an open doorway leading to another large room. Makeshift cots are strewn about these adjoining caverns, and several individuals in gray robes slumber here peacefully despite the flickering torchlight. (unless y'all stumble bumble about and make a lot of noise. Everyone make a stealth check - this is a group stealth check to see if the cultists remain asleep =D)

Katarina stealth: 16

Davis Stealth: 8
