"Not all maligned semi-omnipotent bein's are bad, ya know," Mist quips offhandedly. "Sometimes yeh jus' have t' get t' know an aberration or demon lord or other, unknown subaqueous creature before passin' judgement."

The not-so-little halfling (threequarterling?) swims to stand near the door. "Questionable child labor practices aside (who sends minors down into a pit to work??), I think Mango here has things pretty well under control. What say we indulge in a bit of the frivolity the Abysmal Festival has to offer and get a bite to eat? I'm starvin'."

"You are correct Varlan."  Then Mago turns to Kraven, "He is not normally like this, I am trying to help him."  and then continues with Varlan, "Cipactli is the Demon who’s demise the Festival is for, the namesake of the trench itself.  In the earliest days, Cipactli was a mindless sea monster created by the gods as a means of disposing of discarded ideas. Years of being fed Creation’s rejects sparked intelligence.  Legend has it that Cipactli tired of waiting for scraps, so they scoured the ocean for a decent meal and found the four primal wind spirits. The primal spirits laughed and teased the sea monster, thinking themselves safe in the sky until Cipactli demonstrated incredible cunning and tricked one of them, and started to eat them all.  With their dying breath, the last of the Wind Spirit cursed Cipactli - the monster would never know satisfaction.  Cipactli claimed their strength and ascended into the ranks of the demon lords.  The gods saw the destruction Cipactli left in their wake and banished their former creation to the abyss, but he is always trying to get out, get free and back to this plane.”

“It will take several hours to prepare the Kraken Slick so please if you could hurry with bringing it back.”

Helping him with what, Kraven wonders then shrugs, make no real different to me anyway.

Turning to Mist, "Guess we head off to to bring the slick back and then we can do what ever needs to be done while we wait for him to finish?"

Varlan takes a few steps back, "So ... this fellow worships the Demon ... or do you think, perhaps, that he has in fact just seen it and suffers some malady as a result?"

"NO ONE here worships Cipactli, something has infected him."

At the mention of infection Varlan takes another step back, "Is it ... infectious? And, I suppose, is there anything we might be able to do to help cure the fellow? He may have valuable information."

He looks at the others to see if they agree with his comments...

Jecob: "Common infections can be healed with a touch. Anything that can't be healed can be burned out with holy radiance."

(Not very useful, but he is willing to provide help.)

"I doubt he saw Cipactli, but one of their demondes possibly. I do not have the best of medical care, nor do I have a healer with enough favors.  I have been trying the best that I can, but if you wish to try and help, please do."

Varlan looks around his companions; he willing to try his hand at a treatment but would prefer to help someone more skilled.

Kraven shrugs his feathered shoulder and reaches into his backpack and pulls out a vial and pours the contents down the throat of the mer-folk.

Potion of Healing: 8

While he waits for a result from the potion, Varlan stares pontedly at Kuatho and Jecob whom he has often heard discussing the healing arts and occasionally seen helping the crew with the inevitable minor injuries resulting from from their work. He looks ready to help, should they choose to act.

Kuatho steps forward since he is somewhat versed in the medical arts.  At first he bends over Orilla trying to assess the nature of his injuries further and what might best help the injured merfolk.  His tentacles waving, his arms move over him and his eyes assess the patient, looking him over for wounds or signs of illness.  After he is done with his assessment, he uses his ki to derive further healing for Orilla, hoping that it will help.  

Medicine check : 25 

Hand of Healing : heals for 7 hit points.

(( @Twombley advantage from help ))

Jecob is willing to do a disease-curing lay-on-hands or a Lesser Restoration, but he has to be told to do it.

He doesn't know anatomy. He is a bodyguard, not a doctor.
(...Except now that I've checked it, he does have Medicine proficiency... hmm...)

If Kuatho is looking puzzled and if there is an opportunity, then Jecob will do his own examination of the patient.
Medicine check (rolled in the Game Log):

(Kuatho 2nd medicine check, for advantage) : 10 

Jecob While you are examining your medical history is not helping, but you start to see some marks on the body, and notice something in the eyes that you have read about.  Demonic possessions are not one size fits all, and portals from one plane to another are like any other door, if the door is too small you can’t fit through it, but they can grow in size.  Orilla is being controlled by some kind of demon.  You attempt to help him, it only helps a little, just enough for him to speak in common.

“My father comes, bearing in his wake the ocean of blood. By the power of the star, we break the barriers.”

He then returns to his original state but falls asleep.

Kraven sighs and repeats, "By the power of the star." Then he swears, "Guess we do know where we need to go next then, after finishing helping with what we need to do around here first. Sounds like our fragment is at the bottom of this rift and potentially in another realm."

Mist shakes his head from the doorway.

"That blasted rock... Been more trouble than it's worth. Gonna have to talk to that cranky old geezer about a raise when we get back."

He scratches his chin and shrugs. "We were headed down there to look for it anyway. At least now we've got confirmation. Looks like it's farm, back here, get drunk at this Abysmal Festival (seems they could've come up with a more cheerful name), try to get a decent night's sleep, back here for the Krack Yack, then down to steal a hunk o' heavenly hematite from a demon lord. All in a day's work, eh? Er... Two days, I guess."

Raising an eyebrow and bouncing on the balls of his feet, he anxiously looks to the door, clearly ready to head out.

Varlan just stares at the man as he speaks then backs away. "Whatever that is -- and I've got no clue -- it doesn't sound good."

Turning to Mist he nods, "Aye, I'm with you. Farm it is."

He starts to make his way out of the building and then towards the farm, waiting to make sure that the others are following.

(( I'm assuming we have directions? ))

Kraven nods at Mists words and join him at the door.
