(Updated map)

Sneaking back up the steps and across the main chamber, you open the southern door and proceed down similar steps to a smaller chamber (15'x25') with an opening in the NE wall (just like Davis thought!) This vault contains six pedestals, each bearing treasure and with a carving encircling the base. They all read, “What good are treasures when home is denied?”  The following items rest atop the pedestals: 

• 2,200 gp in neatly stacked piles
• A golden helmet (worth 280 gp)
• A Driftglobe with a map of the gate towns of the Outlands carved on it
• A Necklace of Adaptation bearing the inscription “My breath is yours, Kevetta—take it”
• A book titled Out of the Endless Prison, outlining methods of escaping the prison-plane of Carceri (worth 500 gp to a planar scholar.) Eldon promises to buy the book once returned to Neverwinter...
• A snow globe containing a miniature replica of the city of Neverwinter (worth 350 gp)

"This looks like a trap," Vanizi says. "Maybe one takes us back to Neverwinter? Or perhaps they're all supposed to distract us from the real way back. Are we looking for a portal? Or does anyone even know?" 

"Ooh shiny!" Zyl runs over and starts picking things up, shaking the snowglobe and looking at the other globe, then the necklace and things as well.

Vesta frowns a bit as Zyl starts taking the items.

"It feels wrong," she says quietly. "Like grave robbing. Although, by the look of it, no one has visited this tomb in quite some time. Perhaps it's all right..."

She starts looking around the room, looking for any signs of a portal back to Neverwinter. "Many of these items have something to do with Neverwinter. There's got to be something else in this room..."

Investigation - 11

Shockingly, these treasures are not trapped! The only other aspect of this room to note is the other set of steps in the NE corner (leading north) heading down even deeper into the ground! The steps go about 10' and end on a small flat area with a stout wooden door leading north. (Map again)

Vesta: 

Davis smiles at Zyl's excitement over the globes, and shares a sigh of relief with Vesta, when nothing appears to happen. "I understand your concern about taking things from a tomb Vesta" the paladin says, "though if it can aid us in our quest to stop the cult and their evil god, perhaps it is better served in our hands?"

Davis will not take any treasure, unless the helmet reveals it self to be magical, but he has no qualms of others taking what they believe to be right.

Arcana on helm: 20 (not nat)

"I suppose..." Vanizi says as she watches Zyl just grab things. "The snow globe seems to have the most obvious connection to Neverwinter," she says in response to Vesta's comment. "But maybe we should see what's in the other room?" she suggests. "Perhaps it will make things clearer about how to get back to Neverwinter."

Davis discovers nothing magical about the helmet...it's showy and well crafted, but not very practical! 

When you decide to move on:

Vesta peruses the treasures, musing to herself. "Isolation...loneliness...these seem to be recurring themes for the Dolindars," she says. "I don't believe they thought they even needed these treasures anymore." She nods at Davis, agreeing with his assessment. "I think it's all right if we take them."

As they enter the second chamber, Vesta stops, pausing to examine the phrase written on the tiles. "There it is again...this idea that they could never return home. I don't understand. How are we to return to Neverwinter if the Dolindars believed they were trapped here?" 

Vanizi shrugs. "I guess we take the items," she adds as others appear to be agreeing to do that. 

She follows down to this new chamber. "Does seem like a lot about being trapped. But we were told this was the way back to Neverwinter. Or you think perhaps we were deceived?"  She motions towards the door to the east. "Guess there's one more place to look. Though with an inscription like that it certainly doesn't sound like the way back!" 

"Well that's just dumb. Why tell us all spooky like that this is the way back and get us into a crypt that tells us there's no way home." Zyl crossed her arms and huffed. "I'd almost rather go beat up mister creepy arms in that other room. At least the snowglobe is pretty though." Zyl plops down on the floor and plays with the globe.

(Can she make a check to see if can put 1 and 1 together somehow, or see something else?)

"My first thought was that Dolindar was an anagram of No World to Return', but there is no I or A. Hmm..." Davis says looking at the door and tiles.

He will look at the tiles, see if anything stands out on them, like they are buttons, can move, etc.

Investigation: 9 (or 20 if anyone helps the little guy)

Yes, each letter of the name and the phrase is on a separate tile that looks like you can press it in. Perhaps one letter from each word can be selected that will make a word to open the door...

So...pushing any buttons? Or maybe investigating the door more?

Vanizi takes a closer look at the tiles once Davis points out the letters are on individual tiles. "Well? Do we spell something? There's... a 'D' and an 'O' and another 'O' and an 'R'.  That's all I can think of." she says. "Or maybe the door can just open?"  She takes a moment to examine the door. Does it have a knob or handle? Keyhole?   (Perception: 24)

There is no handle nor a keyhole. Clearly, the tiles are a puzzle. (I'm going to move this forward for y'all. It's gonna hurt your psyche a little, but I don't want to prolong your actual mental anguish =)

As the group examines the puzzle and pushes in letters, several things happen. First, pushing a single letter in any word (including the name Dolindar) causes the entire word to sink into the door with a click. You soon find out that entering the wrong word (like 'doors') resets all tiles/words and you feel a wave of painful loneliness. (Everyone make a DC16 Cha save, taking 20 psychic damage on a failed save or half as much damage on a successful one.)

But you also see a small mechanism below the phrase “NO WORLD TO RETURN” when the letters reset. You can manipulate that mechanism with thieves' tools and perhaps bypass the lock! (DC16 Sleight of Hand with proficiency on thieves' tools) 

[If your close enough to the door to roll damage, your close enough for Davis' Aura of Protection, so add +5 to your Save!]

Cha: 38

"Ouch! Damn Traps" the paladin says. 

CHA: 7+5 = 12

"OWWWWWWW!!!!!!!!! MY HEAD!!!" Zyl instinctively screams as the trap is triggered. "I hate this place!" Zyl sits down and sulks until someone disables the trap, or she'll keep pressing random buttons.

(Vanizi CHA Save: 33)

Although able to mostly resist the effect of the trap, it is still annoying to Vanizi. "There! Who can disable the thing?" she points to the mechanism below the letters. 

Katarina's Charisma save: 19 (+5 if she's in the Paladin's aura for a total of 24)

"Ow... that wasn't fair!" Katarina snaps, more in exasperation than actual pain.

(Sorry all for the quiet, I've been a total mess for a while)
