"Well, sounds like we have to kill some underwater zombies. Thanks for your help, I guess. Anyone have any spells that can help surface-dwellers breathe air?"

Insight, just in case: 10

The hags let you be, and cause no trouble. They figure you're doomed anyway, and walk away from you all cautiously while laughing at you all.

AREA 4 - MAIN ENTRY

Pieces of broken planking and debris reinforce the damaged north doors of this room, whose floor and walls are spattered by bloodstains. A twisted padlock lies at the foot of the north doors, and the south doors have been nearly ripped from their hinges. Arrow slits are visible in the east wall, shrouded by cobwebs. The west wall displays patches where similar arrow slits have been bricked over. The arrow slits are 3 feet above the floor and 6 inches wide; the area beyond cannot be seen because of the spiderwebs.

Sloop excitedly does his rogue-assigned tasks, trying to make himself feel useful:

DC16 Perception check: 19

DC14 Survival check: 12

Perception: 27

Survival: 20

There are numerous humanoid tracks in the blood and dirt streaking the floor. There are more than a dozen individual sets of tracks, some of which are outlined by a thick crust of salt.

AREA 7 - SCULLERY

Stairs rise to a railed balcony that covers two walls of this large, vaulted chamber. The balcony stands ten feet above the floor, with heavy crossbeams above reinforcing the twenty-foot-high, slate-tiled ceiling. Here and there, missing ceiling tiles have been covered over with thatch. A large, rusty metal tub and a broken wooden frame stand near the staircase. The floor shows spatters of blood and obvious signs of a recent scuffle.

DC 14 Intelligence (Investigation) check: ?????

Those of you who pass along the hallway between this area and area 15 can see that a doorway in the north wall has been bricked over. Any room on the map is open to explore.

Investigation: 10

(If, at any time, you need me to repost a map of the hermitage and where you've been, I know that might be helpful as some of these explorations sometimes get long or people lose orientation of where they are and don't wanna scroll back through 3 pages of dialog to revisit the map.)

Sloop quietly paces around the skullery, hand stuffed under his chin in deep concentration. An obvious look of confusion spread across his face, as he seems lost in thought.

DC14 Investigation check: 0

...so lost in thought, he slams into the side of Kali who is standing there like a brick wall. Falling over, he completely falls flat on his butt. 

Investigation: 16

Chandor surveys the scene, trying to Columbo that blood splatter.

Investigation: 19

Kali snorts down to Sloop falling on his ass and picks him up by the nape of his neck then gently settles him back on the ground. “Watch where you’re going, little man. Just stand back and let the professionals do the work, yeah?”

Several people were recently slain here — including someone who was drowned in the tub. The blood spatters on the floor are a day old at most. You guys also notices a few more recent tracks, suggesting that at least one person survived the onslaught. It’s not clear in which direction the survivor fled.

Carrhae moves back to the bricked up doorway. "Wait everyone, I think that there might be something behind this door. Kali, can you come over here and break this down with me?" And Carrhae will Help Kali do whatever needs to be done to bust down the door.

Kool-Aid man entrance (with Carrhae): 17

”OH YEAH!” 

AREA 5 - MIDDEN

A foul stench permeates this dark room, which holds a pile of filth beneath a trapdoor in the ceiling. A ladder is bolted to the west wall below the trapdoor. The bricked-over outlines of three arrow slits line the east wall, and an entire doorway has been bricked up to the south. Five giant rats slither and skitter through the pile of waste, they are easily dispatched.

Something about being around Kali got Carrhae fired up and she joins her first mate in charging through the wall, even joining in with her cry of "OH YEAH!" despite the morbid atmosphere. Once both women have passed, Carrhae gives Kali that bad-ass handshake from Predator. Then her face scrunches up when she realizes that they just burst into a bathroom.

Erriviel holds his nose at the stink, "Not the most delightful of rooms to break into, although there appears to be something to investigate."

“This smell ain’t nothin’,” Kali forces a grin to the others despite the stench assaulting her nose, managing to hold back a cough as she takes a closer look at the ladder.

Investigation (or perception add +2 to this roll): 15

You can tell there is an upper floor to this place.

“Up we go then!” And she climbs up the ladder and hopefully doesn’t ******* die.
