Bryony cries out in pain and drops to her knees. She is barely conscious and shivering.

"Help...something...attacked me...from inside...," she gasps.

Bryony will take the Dodge action.

"I'll be fine. Protect Byrony." Syzygy calls to Kimberley. Syzygy refuses to return Qelline's kindness with bad news. 

Quinn runs to Bryony and drops to her side. He pulls out the last of potion of healing he found in King Klarg’s thrown and hands it to Bryony. 

“Quick, take this!”

Jurgen takes out the rope from his pack and lowers it to Syzygy. 

He checks the area to try to see where this mental disturbance is coming from.

Potion of Healing: 7

Kimberley realised too late that Bryony was in actual distress and watched as she was given the potion......oh, well done.....great cleric you are.....

Kimberley nodded to Syzygy and moved toward Bryony with an apologetic half smile towards Quinn.

" What did it feel like.....where there any images or sounds....smells?"

When he’s caught his breath, Syzygy stands, retrieves the wooden pendant that caught his eye, then climbs the rope. 

Jurgen looks about to see who or what is attacking them mentally.

Bryony quaffs Quinn's potion and begins to feel a little better.

Quinn, however, suddenly does not. Make a DC12 CON Save or take 9 necrotic damage.

Syzygy grabs the wooden pendant and rope, and begins to pull himself out, with Jurgen's help. (He manages to get all the way up out of the crevasse.)
Jurgen: Investigation check: 10

Jurgen, focusing on the immediate nature of his intrusive thought and watching Bryony nearly go down and Quinn grapple with a similar attack, realizes that the closest hiding place would be behind the nearby stone column. Sure enough, he sees a flicker of movement from the dim shadow it casts.... Something or someone is hiding behind it.

Quinn, Kimberly, and Bryony may act next. (Quinn after DC12 CON Save.)

Bryony quaffs the potion and looks gratefully at Quinn.

"It felt so cold...like a part of me had died," she said with a shiver.

The halfling looks around for the source of the attack. "Where did it come from?"

She gets her sword and dagger ready to attack the first hostile creature she sees.

Jurgen points to the flicker and indicates someone is over there. 

Kimberley takes her mace ( with Light having been previously cast on it as they entered) and tosses it lightly towards the column hoping the illumination will reveal who is there.

Jurgen will ready his crossbow if it looks like he’ll be attacked 

Quinn feels overcome with an indescribable sensation. The hairs on his very hairy neck stand on end and he feels a chill run up his spine. 

con save: 14

The chill subsides and Quinn charges towards the left side of the stone pillar with his battle axe drawn. As he rounds the bend he swings at whatever threat, if any, he sees. 

13 to hit for 12 damage 

"Albrek, ally of Silden and The Lord's Alliance?" Syzygy shouts wondering if it's the trickery of a wizard harming the party. 

Quinn shakes off the alarming feeling, and rushes forward in the direction Jurgen indicated. Kimberley's mace clatters on the floor nearby, illuminating the scene behind the column for him: A deformed humanoid creature with nasty-looking talons and a single great eye hides here. It jumps in surprise, deftly dodging Quinn's axe.

Quinn can sense its great hunger. ...It is ravenously hunger and just wants to eat.... Why won't the strangers die so it can feast?...  Quinn can feel the alien thoughts entering his head on their own accord.

It springs away, racing deeper into the cavern, over the northern bridge, and behind the other column. Syzygy's words go unanswered.

Quinn may use his reaction for an opportunity attack as it retreats.
Bryony may use her readied action to make a ranged attack with her dagger as it runs.

Jurgen and Syzygy may have their turns next. But the creature is no longer visible by the time they realize what has happened; the thing has completely hidden behind the far stone column.

...Maybe they have dead food they will give... Quinn can hear it thinking. 

Kimberley stared in horror at the creature as she moved to retrieve her Moons-Hand mace, " What in the Hells is that?"

To hit: 12

Quinn slashes at the...thing as it runs off, but he's distracted by the voices in his head and he misses. Quinn shakes his head and looks at the others.

"That...thing. I can hear it's thoughts in my head!..Does it speak to you too?"

Not a wizard then. Syzygy thinks back to what Byrony just said ‘Cold… like a part of me died.’ Whatever it was Syzygy’s skin shivered, delighted, craving the sweet sting of the necrotic.

Syzygy rushes towards the northern bridge. He checks to see if it’s secure.
