Road to Phandalin

Nobody will at least send Karasym beyond the ward if need be to further investigate the general area within 50ft of the camp, if only to assuage Zurzg. He would also check the goblin over, if allowed to, making sure the goblin hadn't somehow been adversely affected by the berry.

Medicine: 13.

Karasym's Hunting: 10.
Karasym's Sneaking: 15.
(Has 10ft Blindsight, if it comes up)

Even if nothing comes of either investigations, Nobody continued his watch more on edge and unable to get any further studying done. Ultimately, Nobody informed Otrav about the possibilities with the berries prior to originally taken his rest. Unfortunately, between his own limited alchemy supplies and learning in the subject, he himself wasn't confident about being able to do the work with any absolute guarantee of success. For that, he followed up promptly with his usual stuttered apologies.

(By my reckoning Nobody still has 5 hours worth of studying left on the Alchemy Book before he becomes proficient. But do correct me if I'm wrong Dm!)

Using the berries and her new poisoner's kit for the first time, Otrov is excited but cautious - a weird combination of feelings for the halfling and, mixed with her profound apprehension about the talk of doppelgängers, causes her no small amount of anxiety. But when she successfully concocts the belladonna poison, she can’t explain the joy she feels!
She knows this isn’t a contact poison but wonders if she might be able to coat her bolt tips with the stuff. 

She spends the rest of her watch listening and looking for potential trouble. Looking at Margret, she wonders what it must be like to be her - so tall and pretty and strong, and able to know what it’s like to fly!  She practices trying to move her face to look a bit like the fierce warrior wizard.  She's rewarded with a sore jaw and cheeks.   Sighing, she goes back to watching and waiting. I wish I could see in the dark, she thinks to herself, as the shadows from the waning sun begin to creep in. Soon, the goblin awakes and she jostles Margret from her trance and goes to sleep, fitful as it is...

Zurzg berries seam to be goodberries. And Zurzg appears to be his normal self. Karasym doesn‘t find any clues. If something was there, it moved past your wards undetected and vanished into thin air afterwards. Beside that nothing happens during the night.

The next morning, you see Kai meditating when the sun rises. She calls you all together: „ I am going to perform a spell that will prevent you from intentionally lying. You may try to resist or you can simply give in to the spell, either way, i will know who is effected. Also the spell will only work here where i cast it, once you move away you will feel the spell vanishing. Once you feel the spell, please state your name and if you had any involvement  in killing Relgalyn or Grista.“

Kai will cast zone of truth  (Charisma save DC 13) around you.

Zurzg jumps up looking around in excitement: „I‘m Zurzg, big warrior, i will be king of Goblins. I didn‘t kill Relgalyn, but i took Gristas book. I don‘t know if that killed her, maybe it made her sad.“
Next is Gundren: „I am Gundren Rockseeker, i hired two of you to escort mining supplies for me and my brothers to Phandalin. I wasn‘t involved in the deaths of Relgalyn or Grista.“

Kai nods at the two before she looks at you.

"I am Dain Ironfist,"  Dain speaks up with a shrug.  "I am an artificer and wizard, having helped to warn those in this area about the dragon, prior to meeting up with you lot.  I had nothing to do in the deaths of Relgalyn or Grista."

Margret groggily shrugs whishing Kai could of done this in town. Leaving her weapons where they lay. She moves into the area of effect

"I am Margret Thatchhold and I swear that I had nothing to do with the murders of Grista or Relgalyn. Other than to try and find their killer!"

Then as she walks back out of the spell she tests the new bond between her and Talon holding her hand out in a move as she was using it to block an imaginary blow she summons it to her hand

"And avenge them"

Setting Marco in flight no further than a hundred feet above to keep watch sheathing her sword she helps break camp.

Otrov steps into the zone cautiously: “uhh, hi, I’m  Otrov Malo, from Neverwinter. Long time halfling but first time zone of truther.  I hereby declare that I had nothing to do with either murder.”

Then steps out Of the zone near Margret and immediately readies the Prick for a wrong and hostile answer.....

(I'm commander shepherd, and this is my favorite shop in the citadel...)

Nobody actually looks somewhat nervous when it comes to his turn. More nervous than anyone has seen him, and yet he did submit to the spell and would remain within it so long as it's up. After clearing his throat however, the tiefling looks to the ground as he spoke his piece.

"M-my name... I-I.... I prefer to go by the name Nobody, for that is what I must be for my my family's sake. N-not that I mind it, as I did come up with it in the first place... heh... O-oh, and, uh... I don't think I had any direct involvement in the killing of either Relgalyn or Grista." He replied as Karasym lazily curled around the base of a horn.

Kai confirms that everyone was under the spell and at least beleaved to speak the truth.

(Clerics, Artificer and Druids can change their spells as part if a long rest, Kai simply didn't prepare that spell yesterday.)

Before you leave she also casts Aid on Margret, Otrov and Nobody. She apologise to Dain, but she can only cast it on three people.

This is a max HP increase and stacks with Temp HP. 

"Thankyou Kai" Margret says as she receives the extra five hp and feels healthier, her wound just a scar now  after the rest.

She feels that Moss must be nearby watching over us remembering her arm being engulfed by the giants warm grip. And the stories of her turning invisible from the others.

"So shall we go"

"Ooooh," Otrov shivers in delight as the Kai's spell takes hold.  "Thank you, dear!"

You quickly break up camp, but you kept the camp low profile, so there is not much to hide in the first place. Gundren navigates you through the valley. You made your camp in side arm of the main canyon and need to backtrack a little bit, but over all it is only a short hike before Gundren stops and points out the slope of a hill. „Behind those trees is another side arm of the canyon, only a few minutes walk and there should be the entrance to the mine.“

Otrov

"Maybe we should send a scout or two up ahead first?" she will suggest to those with familiars...

"On it." Dain says as Sabastian zips off ahead to do some scouting.

Nobody gives his thanks to Kai in an awkward bow before following along after the others. Once they're close and the suggestion is made, Nobody breathes a sigh of relief when Dain sends off his own. Two might even be better, but the tiefling was secretly thankful of not needing to risk sacrificing Karasym. At least not yet. At that, he actually puts him away in its pocket dimension for the time being and sat down to wait for the report.

Margret keeps Marco within 100ft from the party checking for potential ambush

"Well, it seem our goal is near."

She waits for Dains report

Otrov tugs at margrets sleeve: “Gundren didn’t do the truthy thing...should we be worried?”

"Um he actually did my friend, I guess you were distracted by, bacon?"

Zurzg jumps up looking around in excitement: „I‘m Zurzg, big warrior, i will be king of Goblins. I didn‘t kill Relgalyn, but i took Gristas book. I don‘t know if that killed her, maybe it made her sad.“
Next is Gundren: „I am Gundren Rockseeker, i hired two of you to escort mining supplies for me and my brothers to Phandalin. I wasn‘t involved in the deaths of Relgalyn or Grista.“

Kai nods at the two before she looks at you.

“Oh good good.  I think I was distracted”

Sebastian flies over the ridge towards the direction Gundren indicated. Quickly he notices sights of a recent excavation and after some searching, he discovers a recently digged tunnel entrance hidden behind a large rock. The entrance is just over 5ft high, so Nobody and Margret may need to crouch a little to get inside.

"Ok, found the entrance..."  Dain says as he blinks his eyes open after looking through Sabastian's eyes.  He glances around, then would lead the others towards what the tryssm had located.
