Eima drops another zombie! And the zombies fail their save for some more minor fire pain.

Tez holds position!

Tymm drops yet another!

Sky flames another zombie good! (Nat 20 for 8 fire damage!)

(For the sake of moving things along, we're going to assume you finish the last few zombies handily, leaving just a pile of dead undead around the door to the chamber there)

Combat over.

Tymm looks around at the carnage and giggles to himself. “That was fun.”

When sounds of the battle have finished, Tez returns to the large chamber picking up his tiny companion on the way (I assume after a minute or two everyone should have 11 temporary HP again). "Glad you enjoyed yourself," Tez says with a wide smile on his face, "I, for one, prefer to stay clear from such creatures which I couldn't if everyone thinks like me. Now, let's see what they were guarding here." Tez inspects the room first visually from the doorway and if it seems safe, he enters to get a closer look at what might have drawn his attention (Perception: 14, including 1 from Guidance)

"I must concur. Your work with that axe was positively smashing!" smiles Eima. She waves her hand to sound some triumphant music for the party's victory. "So many zombies. And for what?" she wonders. She starts looking around on the Western side of the room, keying off any findings Tezzy makes, for any unusual grooves in the wall.

Investigation: 17+5 = 22

Other than the statue on the west all and the pile of dead zombies, there is an exit on the southeast corner of the room, but that is about all there is here now.

Tez tries to identify the statue. Is there an inscription or perhaps he remembers something he heard about what it portrays. (Perception: 7, for an inscription, History: 12, for a historic figure, Religion 20, if it is a god or something)

(Religion is appropriate here) Tez recognizes it as a holy symbol of Oghma, god of knowledge and patron to bards and wizards. In fact, while the statue is pretty dirty, if it had been cleaned off and worshiped appropriately, it might have even helped with all the zombies.

Knowing that, Tez tries his best to clean the statue and provide an appropriate prayer for the statue to continue watching over the room. „Beats me, what was the purpose of this room. Maybe the scholar whose grave we found earlier was a follower. Anyway, I think we have to continue there,“ Tez says pointing towards the door southeast.

"Fair enough." says Eima. "Hopefully no more undead nasties." She looks at Tymmy, "You lead, big guy, and I'll follow?" If Tymmy agrees, she'll place herself second in the marching order.

Tymm just flashes Eima a wink and a wry grin and saunters towards the southeast exit

Following the passage just a little ways, it widens slightly where you see a double door made of green-tinged stone that seals off further progression into the catacombs. Facing the double door is a large carving of a grinning skull; one eye socket bears a wide eyeball with a jeweled iris, while the other is an empty divot.

“Hey, uhhh, do you think our eyeball goes in that empty hole?” Tymm asks while striking what he thinks is a thoughtful and pensive pose.

„Let’s see,” Tez approaches the eye to the door and observes how it reacts and puts it in if it seems to him that’s where it wants to go.

Once placed there, the eyeball pulses with sickly green light, and the double door swings open to reveal a staircase leading further down.

"Exciting!" says Eima as the staircase opens up. "I'm glad that plan worked." She takes a look at the staircase for any traps before the group starts heading down.

Investigation: 6+5 = 11
Perception: 19+3 = 22

If the companions are very quiet and are paying close attention, they might be able to hear Tymm’s ego swelling. His idea worked!! He’s a smart guy just like his companions!!

"Good idea, Tymm!" Tez congratulates. "We're definitely on the right path," he says and commences to climb down the stairs once they are declared save by Eima. 

There are no traps on the stairs.

The bottom of the stairway opens into a wide 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.

Tez quizzingly eyes the black candles with green flame. Is this part of some ritual that he recalls reading about? (Arcana: 26) Or the eyeball? Is this eyeball actually similar to the one they have? If there was any doubt before, now they can be sure they are in the right place. Wary of hiding cultists, Tez enters silently, slowly and carefully, intending to dodge incoming attacks or triggered traps.
