In his mind Gryrigs biggest concern, now that the Orc has closed the window and disappeared again, is this slobbering boar. He's not actually worried about being eaten, but rather about how in avernus he's going to spin this into the heroic tale. After some thinking, he decides that maybe he'll just omit this one altogether from the verse

Kat will slip through the darkness to try to get visual on the source of the sound Gryrig alerted them to.

Azzure moves forward taking up position right behind Duncan, whispering “What the hell is going on in there?  Can you see?”  He strains to look forward and take in what is happening.

Torman watches as Azzure moves forward then his head flicks back the way they came, a longing expression on his face. Whatever is ahead he feels certain it is unlikely yo be friendly, shenanigans with the boar aside. Despite his better judgement he follows Azzure, though not very closely.

Gyrig hears Torman's voice, faint in his ear. "I believe they like food," he says. "But I ... ah ... don't make it angry."

You guys can't see the source of the sound from where you are But Duncan understands the words "Fight, Fight" is what's being chanted.

Gyrig is licked cleaner than he was when he came to the pen. The giant boar moves back further to, wallow.

 (I guess that's one way to shower and clean up.)

Assuming he is now no longer grappled, Gryrig will move stealthily to the Longhouse. Any chance he can peek in through e.g. a crack in the shutters?

The window is made of solid wood. Being underground who would want to look outside to see such a scenic view?

 (I get that it's an opaque shutter. But I was expecting Orc workmanship to be imperfect, so that there must be some holes or gaps to peek through without actually opening the shutters. If that's totally impossible, Gryrig will very carefully open the shutters a tiny bit, just enough to peek in)

Duncan:

Waiting patiently for the scouts, Duncan is hopeful that the orcs are having some kind of ritual combat that might distract them from his Allie’s’ approach.  Having found a decent hiding place, he remains still so that his heavy armor doesn’t give them away.

Torman breathes a sigh of relief: He had been getting fidgety, wondering if he should try to help, but seeing Duncan settle in, he also calms himself and waits.

Gryrig hears Torman's voice, a whisper in the air driven by magic, "How are you going?" He asks, then "You can reply, no-one will hear."

 "So far, so good. The slobbering beast has left me alone at last. Now I'm trying to find out what's in this Longhouse. In this hovel of a cave, this looks like a place where we might find valuables or where they would keep any paperwork. If anyone in this uncultured mob can even write. I'm just going to try to peak inside"

Torman relays this information to each of his companions then looks in the direction of Gryrig, "I've told the others, and will keep in touch. Any news? No need to reply if none."

Every few seconds after that he hears the faint whisper asking for news...

Duncan:

Whispering back to Torman, Duncan relays, “They are chanting, ‘ Fight, Fight’, so perhaps there is some kind of ritual combat they are engaging in right now.”

 Gyrig finds a crack in the shutter, he sees a harem of female orcs inside. It looks like one is approaching the shutter. 

Azzure continues to move forward, moving behind the next large rock, trying to see further into cavern and get into a support position.  He whispers to himself, “Where are they…”

Wondering if they are making slaves fight each other, Kat will slip through the dark to try to get eyes on whatever is going on. 

((DM, can you move her token on the map to wherever that might be? I don't want to scout further than I/she can while remaining out of sight. And if it's not possible for her to move through the dark to get places, that'd be good to know too, since it seems they've a number of firepits here.))

The light of the bonfires fill the whole cavern, though shadows are cast from boulders. You guys have found cover behind boulders so far. Gyrig has used the disguise self spell to move around freely. 

Course Kat is, a gloom-stalker right? Doesn't she have means other than the cool invisible to darkvision thing?

((Yeah, but only while in darkness to creatures with darkvision that would otherwise be able to see her. It doesn't help her if she's in dim light. If everything is all bright light or dim light in this cavern, she'll have to rely on just being sneaky!))

Kat will slip further into the cavern along the south side, away from the boar, trying to get more visual on what's in here.

 Gyrig finds a crack in the shutter, he sees a harem of female orcs inside. It looks like one is approaching the shutter. 

Do they look like they are slaves or otherwise unwillingly kept there? E.g. chains/manacles, or anything else to prevent their escape? Or do they look like they are regular Orcs who just live here?

Perception 22 , Insight  8

If they look like they are held there against their will, Gryrig might try his luck: He would stand back and a bit to the side of the window so he would not be in direct sight of everyone inside, but only of the one opening the window. He would then  indicate with gestures for that he means no harm, and would drop his disguise (making sure that wherever he is standing wouldn't be in direct sight of the Orcs around the fire. Then he would hope their either one of these Orcs speaks some common, or that one of his group could come up to help him. Persuasion 9 to calm her and persuade her that we're here to rescue/release them

If instead they look like they are just happy inhabitants and not held against their will, Gryrig will quickly move a little bit along the curved wall to be out of sight of the Orc opening the window. After this Orc disappears out of sight or stops looking, he would then try to make his way back to the others, walking stealthily in the shadows or nonchalantly in the light, still in his Orc disguise.

Getting fidgety again, Torman contacts  Gyrig for an update..."Any news?" he whispers, then relays any reply to his companions.
