(I'm describing Riris as having left her rapier where she fainted because she did pick up the lute, clearly, but she didn't use an action after she woke up to take the rapier on the same turn. With that in mind, here's a turn that never involves attacking Nezzenar because Riris doesn't have a nonlethal option without her weapon.)

Riris's first order of business is stealing the coin from her own mage hand, which, thankfully, was right by her side. Then, she starts moving down until the coin in her hand can light up Nundro, being that around F11 would work, and, as her quick and clever plan, the halfling plays her silly little tune again, preparing with a smile, a joke that's more improvised than the one she waited a minute to tell, but no less well-delivered. "Hey, where are ya goin'? Never heard of coward dwarves, I thought they had an iron will!" That might've doubled up as a Vicious Mockery, but there was more to make a spell than her specific word choice.

DC 13 Wis save or suffer the effects of Hideous Laughter

Mixum will hold any further fire on Nundro at the Dwarf's urging.

He stands ready to make an attack at the next enemy that presents itself. Looking like Nezzaner is down.

Nundro[?] Wisdom Save Vs Riris(DC 13): 11.

With the strangeness still going on with Nundro, Anton aims his next strike to catch Nezzenar in the gut, puncturing a hole right through both the visible barrier, and another hidden one closer to the skin. As the drow fell to the ground clutching the wound before eventually passing out from shock, the spearman is soon marching after the runaway dwarf.

Mixum holds not only his current position, but a shot as well for any more enemies that might show up to the scene. As the fight had not been entirely a quiet one...

Riris hastily rushes after the fleeing dwarf, though not without snagging the lit up coin along the way. Soon after, a jest made at Nundro's expense leaves said dwarf crumbling to the ground in manic laughter. This being despite every effort to fight against the spell, even going so far as to cover his mouth, though to little avail.

Nezzenar lays now in a pool of his own blood, bleeding from wrist and gut. Although he still breathed for the time being, some treatment might be necessary to further insure things.

Pip and Ordrin are now up!

Confused a bit by the Dwarf Nundro attacking them and now fleeing he lets the dwarf pass  He then draws the power of a cantrip to mind and holds off on releasing the attack against Nezzenar unless he becomes aggressive and attacks again.  He is down at the moment, though he is unsure why he has been spared at this point.

"We are not killing Nezzenar for his machinations against all of us and the nearby towns?" he asks.

Hold action Toll the Dead DC 14 WIS save or 9 necrotic damage

"Your anger is well found, Pip, but an execution will not bring comfort to you. Nor me." Ordrin, seeing Nundro is well-tended and Gundren able to join them, approaches Nezzenar. He spits on the ground near the wizard's feet, then kneels to bind him hand and foot, and lastly puts a gag in his mouth. Then he tends to their assailant's wounds, with a thought to Sharindlar that he's earned her favor for this one. "Maybe he knows something useful." Then he stands at the ready, like Pip watching for the wizard to so much as twitch a toe. But not without a few lusty glances at the large emeralds on the statue next to him.

Medicine: 13

Nundro End Turn Wis Save Vs Riris[DC 13]: 18.

(To Ordrin: You do not have anything on Odrin's person to bind him as far as I can see on your sheet to tie up Nezzenar. Same goes for treating wounds, but I'll at least hand wave that part. As I can't imagine a healer going without at least a few bandages or being able to make some makeshift ones for emergencies. Also treating and tying him up would be 2 separate actions anyways.)

Ordrin, seeing the reticence in Pip to not finish the job, tries to assuage his compatriot by claiming there being no comfort to come in doing so. And if that wasn't enough, while tearing what spare cloth he can from the Drow to help binds his wounds, lowering the odds of his bleeding out in the next few minutes, he appeals to Pip's thirst for knowledge. After doing as much as he can there, he cannot help but steal a few lusty glances at the large emeralds in the statue. Which... he could reach after some climbing...

Pip questions the idea of keeping Nezzenar alive at this point, and even prepares a spell to finish the job. However, so long as Nezzenar moved not to attack, the final words to complete the incantation is kept held at the tip of the gnomes tongue.

Nundro maddening laughter peters and dies out after a time: The dwarf finally regaining some control over his faculties. After looking back into the room, and seeing not only Anton, but Gundren making moves to rush his position, the dwarf shakily holds up his hands as if surrender.

Unless the group wishes to continue to attacking Nundro, we can come out of initiative now.

OoC: If he's surrendering and no longer trying to flee, that's fine with me

Seeing the mage down and the dwarf surrendering Pip looks around at the others.

"So, now what?"

Riris does what can only be described as an excited jump as Nundro gives up. "And that's done! Good job, everyone. We just have to make sure he gets here closer so we can talk." She looks back at Anton. "I'm not strong enough to force him to come, so can ya make sure he gets here? Just as a precaution."

"Aye," Ordrin says. "Let's see if he's gotten his senses back." He stows his hammer and shield and approaches Nundro, walking him back into the room and bringing him to Gundren.

 Nundro grimaces seeing Ordrin enter his field of view, but puts forth next to no resistance upon being hauled up to his feet, more or less. About a quarter of the way back into the room, Gundren casts aside his war pick and rushes up to meet Nundro and anyone else that chose to escort the dwarf into the room. "Brother! Are you alright? Do you recognize me now?" Gundren asked, clasping callused hands upon his brother's shoulder.

 In response, Nundro squints and shakes his head a bit, before asking tentatively, "Br.... Brother? Is that you? Whe.... Where are we?" As Nundro is looking about in apparent confusion, Gundren's look of relief turns into one of confusion for just a brief moment. But then he's back to smiling in relief and patting Nundro on the shoulder, "Where in da mines, ya daff bugbear. Our platinum nugget!" He admonishes. Yet its clear in his grinning that he meant nothing really by the insult.

Somewhere along the northern end of the chamber, a pained groan brings attention back to the drow still among the realm of the living. Gundren looks back angrily in the fallen's direction, to the discarded War Pick, and then finally over to the rest of the party as if looking for some direction from there.

Without healing of some kind to restore hit points, the Nezzenar will be too in and out of conscious for answers. If anyone wishes to try and discern in the meantime what was up with Nundro they can certainly try. Just say what it is and how you go about it. And feel free to roll any check you think might be necessary.

Seeing that Ordrin wanted to bind the drow Pip lets the power at his fingertips rescind.  He then digs in his pack and pulls out his rope and tosses it to him.  

"At least bind the man, and gag him for now so he can't cast any spells."

Seeing Nundro return he looks him over.  He ponders for a moment trying to understand the sudden change in his demeanor.

Arcana 9

Riris stands still charred by the fire spell that got her earlier, looking much worse for wear than usual, though that doesn't hamper her mood, as she watches the reunion with a smile on her face. "Ain't this beautiful to see? I'm glad y'all could meet thanks to us." Though, she does wonder... She may be no arcane genius, but her skills spread across the board, and she's also not dense, so maybe she can tell what was going on with Nundro.

Arcana 4

In regards to Nezzenar, her response is very brief. "Only thing I can help ya with is healin' if ya need it."

Ordrin thanks Pip and hogties Nezzenar, then stuffs the wizard's mouth with a strip of his own robes. "Gundren, where does this other passage go? Are we safe here?" Ordrin sits down against the wall next to Nezzenar, both guarding him and making sure he doesn't drift off to the afterlife. "Might be a wee rest could help clear Nundro's head. Else we may be talking to this fella here for help."

Pip & Riris: Unfortunately, neither practical training or "unique" understanding of the weave and magic in general offer much insight into what if any magic had afflicted Nundro. By your best assumptions, most long term sort of magics tend to require conscious focus on the manipulator's part to maintain. Thus, when Nezzenar was eventually incapacitated, any ongoing magic likely dissipated by now. Looking to Nundro, He appears to at least have recovered enough to move and act with purpose. Up until Odrin's comment, in any case.

Ordrin: As you are working on finally binding and gagging the wizard, you notice three things. One, no matter how hard you try, you cannot quite pull or cut free a piece of Nezzenar's cloak. And upon further inspection, you realize that both leather armor and cloak are actually one thing that -- without perhaps his conscious control over it -- loses some of weird altering magic or illusion over it, revealing it to be some form of Mage Armor made to simulate natural armor. The under clothing is real however, and you can tear off something there if you still wish. Secondly, with the magic disrupted, the bracers Nezzenar wore turned into a pair of silver gauntlets with golden filgiree about it. Part of which along the back hand portion has been shaped into a stylized visage of an Ogre.

Nundro appeared confused for half a second, before wincing and rubbing his forehead. "Might be right. Rest would be good." Nundro admits, prompting Gundren to keep a steady hand on his brother's shoulder. "Yer guess is as good as mine on both accounts, Ordrin. We never got this far deep into our own expeditions before I needed to head back to Neverwinter to gather supplies and help with transport. But, I'd wager it at least leads back on the same path as the right one we passed o'er on our way here.." He replied. "As for safe, I think that Drow bastard mentioned sending some folks away to find you lot earlier. Though, they could've just as well been a bluff."

Nundro nods, and then says with some hesitance, "There's a... sort of supply room along that way, and where they kept me... when they weren't busy working me over in here." He said, frowning and looking generally frustrated. He then looks between the Drow, and soon his glaring at him. "I wouldn't be letting that one live though if I were you... can't trust'im."

What is Anton and Mixum doing during all this? Keep watch? Taking a breather? Turning the spider corpses into shish-kabobs of some kind maybe?

Mixum and Charlotte patrol the perimeter and keep watch against incursions. 

Ordrin pulls the bracers off the wizard and stands. "Nundro," he says, pointing a bracer at the dwarf, "it is your right to recover compensation from this one, however you see fit. Gundren, as well, as your kin."

Nundro smiles while Gundren only nods grimly in thanks. However, as Nundro cracking his knuckles and glaring down at the Drow, Gundren started to go for his war pick, before stopping and looking towards the Riris and Pip. ".... Just to be safe, you lot should check out that tunnel. Make sure there aren't any returning forces from that way." Gundren suggested, offering at least an out for those of weaker constitution.

Nundro's smile falters for a second at that. But then, he's nodding along in a sagely manner.

Riris gives Gundren a sweet and innocent-looking smile before nodding. "I hear ya! Come along Pip, we ain't lettin' 'em escape our sights!" And finally, she looks over in the direction of the tunnel, having not spotted it earlier due to the low amount of light in the room.

(Secret roll:)

"Yes, yeah, ok." Pip says a bit distracted not really having an issue with that he thinks the dwarf will do but not really needing to see it either.  

He moves towards the tunnel and peers down it, Archimedes again perched on his shoulder.  If nothing is seen he'll slowly start down it as long as Riris is with him.
