Kei leisurely examines the items they liberated from the treasure room. The two potions are indeedpotion of healing (one common, and the other of Greater Healing), and the bag is in fact a bag of holding.

The armor is half-plate, but it is beautifully crafted, of dwarven make, and very light. Investigation: 9

 ...he's never seen the metal before, and it seems to be non-magical, but it is very high-quality.

"If" Dwal sees the half-plate that Kei is looking over he will say:

"I can have a look at that if'n ya like." Dwal suggests. "I've been known ta know my way around an anvil." 

Peri:

Peri settles into a dry corner to meditate. He's really getting much better at it, and Kei's music seems to help. He can almost reach that state of controlled detachment described in his monastic texts. Maybe if it wasn't so cold and damp... And with that distraction he falls back into his body. Still, getting up and moving about he feels entirely healthy. You're tougher than you look, boyo -- tougher than your friends give you credit for. 'Course, without their healin' you might well be in whatever passes for a gullet in that jade thing. No, best not dwell on that feelin'!

He joins Dwal and Kei by the loot. "So, find anythin' good? A coupla healin' potions -- can't imagine us ever needin' such a thing! And a fancy bag like the nobleman's. Bet you wish you'd had that on our first foray together. You shoulda seen him, Boko. There was this big ol' pile of coins, and Kei's tryin' to find a way to haul it around and still be able to fight -- I've seen parents lay their children to rest with less sorrow than Kei puttin' down those coins!" He guffaws at his own story. That adventure nearly ended in tragedy, but it was good to remember it wasn't all blood and death and terrors.

"What's with the armor? You thinkin' of becoming Sir Kei of The Styes?" He picks up one of the shoulder-cover things -- Poltroons, maybe? Somethin' like that -- and is surprised at its light weight. "This wasn't some poor schlub temple guard's. What is this stuff, Dwal?" Handy sometimes havin' a dwarf along. He can't really mean to hang up his axe after this, can he?

Boko listens to Gerrard, nodding. Then she begins talking in a low tone, for the group to hear, not those behind the door. "It seems your life has improved, then. Your past sounds stultifying and depressing. These fellows have saved you, it seems. In their way. I come from more humble stock. Inland. Always searching for the sea. A passing monk helped me see a broader world, and a way to the shore. I caught the first ship that would have me. I learned a lot on the water, mostly on the same ship, which was, it turns out, absolutely a petty smuggler operation. Never minded fighting ship to ship or sneaking around in the water, whatever the situation called for. I was fast, quiet, and efficient, and valued for it. Then.... the Hold. The Sea Princes took us. We were given the chance to either join to be sunk. The captain chose to join, barely. I went along with piracy to stay alive. Months of, well, you can imagine... and I pushed the issue on deck. The Captain had promised we would break free and desert the Hold. Some of the crew backed me up. Some did not. The Captain did not meet my eyes, peering at the horizon. The Bosun made to agree, and then stabbed me in the back and pushed me into the waves. I floated a bit, shark bait, as a storm arose, a bad one. The ship may or may not have made it. I did not. Sunk deep in the waves, should have died. But I woke up, looking like this. Blue. Purple. Rescued by a druid, of all people. Found purpose. Bringing balance to the coast and the open water, stopping or hurting those who abused the balance or the marine life. From time to time, pecking away at the Hold. Then, just before you found me, I got taken. By that thing. The thing these creeps worship. I am accumulating enemies faster than I can count. I could use some allies. Some friends, even." 

She blinks, and looks around, unaware that she had even been talking as long as she had been. 

Kei 

"Dwal! C'mere" not a request but not an order in the same token, Kei seeks Dwal's council on the dwarven craftsmanship. Peri approaches just as he hands over the breast plate. His fingers linger just a little too long as Dwal takes the armour making it appear as though Kei was unwilling to let it go. "Tell me this is what I think it is!?"

"If I was to become Sir Kei, my first action would to be appoint you as the Court jester!" He smacks Peri across the back of the head. "This is serious Half-baked. If I'm right, this is the stuff of legend. Midral, no no, mathrale. Damn it, it's right there on the tip of my tongue." With anticipation Kei waits for Dwal's trained eye to confirm his suspicion. While Dwal looks over the finely crafted half suit Kei grabs the Potion of Greater Healing. "Think this is more your strength" he tosses the flask to Peri with a wink. 

Dwal pulls out his tools and examines the fine armor. Investigation: 25

 Easy: It's mithral. Mithral Half Plate. For a medium-sized humanoid. Beautiful work, and very light.

 Boko notices that the piece of jade she picked up has transformed into a piece of ugly, crumbly shale. 

Gerrard:

"You have quite the tale, Mistress Boko.  It seems we are both better versions of ourselves as we try to make a difference in this world instead of letting our circumstances sweep us along in the tedium of everyday life," replies Gerrard.

Seeing the jade-turned-shale, Gerrard looks in his own bag for the pieces of jade picked up from the broken statue on Peri's behalf.  If they are shale now as well, he piles them in a corner instead of leaving them in his bag.

Watching the interaction of his friends over the items found, Gerrard is impressed by the beautiful dwarvencrafted armor.  He waits for Dwal to speak about it, wondering how it got to this forsaken place, though he would surely like to see his friend wear such a treasure of his people.

Claiming the glass globe with the tower inside, Gerrard asks, "Master Fenwader, is it safe to shatter this item now that we are outside of the temple proper, or should I wait until we are outside?"

Dwal will relay the information about the armor to Kei.

"Fine piece" he says. "I hope ta make one like it one day."

Peri:

"You're askin' me? How would I know if it's safe? I can't claim to have shattered many magical artifacts; it wasn't one of the qualifications for Able Seaman." In a less sarcastic tone he adds thoughtfully, "If you're leavin' the choice to me -- which is already a bad decision on your part --I'd wait til we're near Peleg's island. I hate the thought of freein' a man from years of bein' marooned, only to have him drown as the tower crumbles under him. Besides, if it does make the whole temple collapse -- and I'm not sayin' that's what happens for sure, but that's how it goes in adventure stories! -- If it does collapse this place we'll never find out what's behind all those other doors."

Gerrard:

Looking at Kei and Dwal, Gerrard suggests, “Perhaps in the meantime, Brother Fiercehammer, you should wear this heirloom of your people.”

At Peri’s words, Gerrard says, “Your plan makes the most sense to me—being ready to help Peleg if his prison crumbles around him due to this unpredictable magic is most wise.”

Having finished his rest, Gerrard stands up and prepares to get back at it, saying, “Shall we finish our exploration here, then?”

Boko nods, not saying anything after her long story. She wonders if she's said too much. But once everyone else is ready to explore, she heads to the westernmost closed door on the map, shifts into a tiger with dark blue stripes, and prepares to pounce on anything dangerous.

Gerrard finds that the jade he picked up has transformed into worthless shale as well; he dumps it in the corner. Boko quietly transforms into a tiger.

The party heads into the mediation room and prepares to reenter the hidden door into the winding subterranean way. "Hey!" shouts Bayleaf. "You ain't leaving me, right? We gotta long voyage ahead to the Styes!"

(What's everyone's marching order? Remember that you may walk two abreast in the passageways, except for Bokotiger, who is Large.)

Kei 

"Hmph. Like he found it or something." He grumbles under his breath at Gerrard's suggestion. In a huff he closes the fancy mirrored bag and walks off to follow Boko. "I'm sure you'll look regal and all Lord Fierceplate" his parting words obviously tinged with jealousy. 

As he approaches Boko he whispers to the spirits in his deck to help guide her actions in the coming moments. 

Peri:

"That's a new look. How many animals can you turn into? No, I know, you can't answer now..." As he takes up a position right behind her, he says a bit quieter, "Sounds like you've picked up quite a few enemies. It also sounds like they're the right kinda enemies, like the ones we've picked up. I'll gladly have you as an ally. We get back to Saltmarsh, we can start workin' on friends. Maybe over a pint or two of Lankus's ale?" He again activates his Eldritch Sight. Just because they've been down these halls before doesn't mean some tricksy devil didn't put down some new magical trap.

Dwal shakes his head and takes 3rd or 4th back.

Boko spots it in the corridor first - a tripwire, strung about 8 or 10 feet from the unopened door.

Peri's Eldritch Sight picks up nothing in the area.

You can simply step over the wire, or you can try to disconnect it. (Thieves' tools would definitely help.)

Boko in tiger form languidly, yet still massively, ranges around the waists of the taller members (and shoulders/heads) of the party in the hallway. Prrt. Prrt?  Prrt. It sounds unnerving coming from the giant throat of a tiger, but it reminds you of a housecat. She butts the side of her head against Peri's shoulder, walking swiftly past, not quite knocking the agile man over but nearly, in response to his invitation to be an ally despite all the enemies, and to share a table over ale, back in town. It's a clear affirmative and a note of gratitude. She loops around to aim at the doorframe, front paws crouching, rear paws settling in place for a pounce, eyes set and pupils dilating, a low growl rumbling from that massive throat, ready for the door to open.

Gerrard:

As they prepare to go back into the tunnels once more, Gerrard answers Bayleaf, saying, “The weather outside is not fit for travel yet…be patient.”

Following Bokotiger and striding along next to Peri, The young noble good-naturedly pushes back against the purring monstrosity, offering a scratch between the ears when necessary to allow him to keep his footing.

Gerrard:

"What's that you have found, Lady Tigress?  A tripwire?" Gerrard says as he brings his glowing rapier close to the ground so he can see the trap's trigger.  Looking to the others, he asks, "Should we try to disable this trip wire, or just mark it so we know where to step over it?"

Unless you have other ideas, everyone can easily step over the tripwire, strung just a few inches above the ground. The door ahead is closed, but looks like it could be pawed open by a large tiger.
