Horatio is silent for a moment, then says, "I think this place is changing me somehow. I can see in darkness now... have been able to for some time. And I summoned magical flaming shackles when running from the hag on the broomstick... I won't need a torch."

Lit by Pud's magic bullet, the party continues a little deeper into the mine, corkscrewing down where it becomes something of a twisting labyrinth. 

The sound of hammering resumes, coming up from the depths, but you see no life or activity here.

Presuming you are staying together as a group, the narrow passages force you into single file. Is Pud (with his light), Matilda, and Titaani (riding Tiny) leading? Is Horatio and Ben bringing up the rear? (Does Horatio need to activate his Stone rune to acquire 120' darkvision? Or is it just if he wants to use its other feature?)

Ben:

As the tunnel gets dark, Ben calls upon the power of Sune and a soft, warm golden light starts emanating from his shield.  Ben will follow the others down further into the cave, watching their backtrail as he goes.

Titaani can lead. 

As the group reaches the corkscrew, however, Titaani stops abruptly, most likely causing the others to bump into her. "Wait! Wait. We could get lost," She says, turning around to speak to the others. "I have an idea, though. Hang on."

Hopping off of Tiny, she whispers something in gnomish and her familiar bounds on ahead. As he does, Titaani's eyes glow purple as she slips into Tiny's senses, seeing what he sees. With her hands, she summons a blank map which begins to form the image of the mine as Tiny moves forward. 

(I'm using voice of the chain master and minor illusion in combination - is this ok?) 

Led by Tiny, the party moves carefully onward and downward, as Titaani carefully maps their progress amidst the distant sound of hammering.

Everyone: Make a DC 19 Constitution saving throw or fall asleep, lulled into a magical slumber by the rhythmic racket of the miners...

Elkhorn: 6
Gleam: (immune)
Amidor: 16
Pollenella: 9
Squirt: 2

Ben:

Note that all allies within 10 feet of Ben get a +3 to saves from his Aura of Protection.

Constitution Save:  8

Constituition save: 8

(( Horatio = 16 with Ben's aura included ))

Con Save: 18 (so close!)

Pud stops in his tracks and listens to the sound.

 "hey...you guys hear that? It sorta sounds like..." Pud collapses to the ground in a heap and falls fast asleep.

Con Save Matilda- 5

Pud, Horatio, Amidor, and Elkhorn all crumple to the ground, fast asleep.
Pollenella and Squirt fall out of the air, bouncing on the hard mine floor.
Titaani joins them (unless that +3 is from something other than Ben.) Tiny DC19 CON Save: 14 )
(Did Matilda roll that 20 with or without Ben's +3? If with, then she's down also.)

Gleam looks around fearfully, preparing to bolt back up and out of the mine. Ben remains alert.

Eight frantic, mouse-sized creatures – evidently the "brigganocks" – arrive a few moments later, each one pushing a tiny wheelbarrow full of ropes and pitons. Spotting Ben, the brigganocks look surprised, turn their wheelbarrows around, and retreat whence they came into the twisting tunnels.

Ben:

Having missed his chance to play asleep and perhaps lure them in, Ben says in Sylvan, "Please, don't run away.  We mean you no harm--we just wish to talk with Golmo."

Persuasion:  23

There is no reply. Most of the party remains asleep, and the brigganocks have vanished. The hammering has stopped again.

Ben:

Sighing, Ben moves over and starts gently waking everyone up, surmising that this might not be the best place for a siesta.

(Are we able to wake up?)

Despite Ben's best efforts to wake them, those who are sleeping remain dead asleep. 

Those who are awake (just Ben? Ben and Matilda?) hear larger bootsteps approaching.

A tall, slender human clad in dark leather armor then appears, their face brightly illuminated by a tiny wisp of light that floats next to another mouse-sized brigganock perched on the human’s shoulder. (You've noticed that a bulb of pale light floats alongside each of the tiny brigganocks.)

“Greetings, trespassers,” says the human with a smile. “Didn’t anyone ever teach you how to knock?”

Then her smile vanishes. "Who are you? Who sent you? The korreds? Creeping Lyn? What do you want?"

Ben:

With empty hands, Ben answers simply, “Knocking is difficult on an open cave, so I called out…twice in fact.  Some of my companions and I are native to the daylight realm and were stolen from at the Witchlight Carnival.  We and those we have joined with along the way have come to set things right—for ourselves, and for all of Prismeer if we can defeat the rest of the hags and restore Zyblina to her rightful place.  Lamorna mentioned Golmo might be able to help us—are you she?”

Pud snores loudly and twitches like a dog mid slumber. This unnatural sleep causes him to have wild and most vivid dreams.

...Pud see's himself from above through the eyes of some creature drifting on a breeze. He appears to be a few years younger than he is now, and he runs carefree and without a limp. He's with his younger brother, their cousin and three of their friends from the village. The group of children are running frantically through a dried up old corn field. The stocks of corn are violently thrashing about and the clouds in the sky are roiling violently as massive thunderheads build up over head.

A loud boom of thunder explodes followed by a crack of lightning that strikes near the children. The concussion of the blast knocks Pud off his feet. The wind is knocked from his lungs and he feels as if he will pass out. A massive drop of icy cold rain hits him square between the eyes and snaps him out of it. 

Pud scrambles to his feet and finds himself alone in the field. He cries out for his brother and cousin. He screams for his friends. But no one answers.

The strong smell of ozone, smoke and ash build up around Pud as he stands in the field alone, screaming.

Another boom of thunder followed by a bright flash of light strikes...

Ben:

Belatedly realizing he had not yet introduced himself, Ben adds, “My name is Ben.  Benjamin the Stonecutter.”

Matilda let the adults do the talking.....she had been enjoying her nap.
