"That's odd," says Passoveloce, "I wonder what could have brought these disparate peoples together here, it seems like it must have been a lemming of an idea." He looks more closely at the bodies to see if he can determine method and time of their demise. He then looks more closely at the "Rubies" from behind Lucas' kneecaps to see if he can determine what it is about them that is not quite right.

"Well, assuming they weren't captured and brought here against their will, then could just as well be they were some rather unlucky adventures themselves. Though what would bring the ding bats here of all places I... couldn't even begin to hazard to guess beyond them finding out about the same thing we're after some years prior." Lucas mused quietly yet loudly enough at least for the party nearby to overhear him. He then regards the door nearby, considering it for a moment, but then following one last glance towards the rubies, opted to backtrack towards the center of the foyer and struck a thoughtful pose. 

... Or at least pretend to be pondering while waiting for the others to examine and explore the other branching paths from the chamber. 

Passoveloce is unable to determine either the exact method or time of demise. All he can ascertain is that given the skeletal nature it was obviously some time ago. He is also unable to determine exactly how the rubies are trapped but he concurs with Lucas’ assessment that are trapped in some way and therefore best - unfortunately - left alone.

As Lucas moves to the double iron door, Passoveloce looks back to the party and signals to them it is all clear.

Corwyn - sword burning brightly - leads the rest of the party across towards the door, When they have travelled about 15 feet into the room Paul mutters quietly “two characters have just come out of an alcove in the western wall and are following us!”

Corwyn:

”Let’s keep going and observe them, with someone stealthy falling in behind them if possible,” murmurs Corwyn as he focuses on continuing to move towards the door.

It is not possible for somebody in the party to get behind the two individuals following them. Also when the party gets to the two iron doors they realise they are locked.So …?

If by some miracle Passoveloce hadn't taken advantage of some trick or magic to comply with Corwyn's request, then by the time they reached the iron door Lucas whispered to the party while pretending not to notice the followers. "Not one fer bloodshed, but best we neutralize'm quick and ask questions of any survivors after." He said. But even as the words left his mouth, so too had the Weave seemed to head them. For about thirty or so feet behind the party did the air grow thick with the scent of lavender. At least that is the scent the groups would be followers would pick up on as Lucas' magic subtly wormed its way into their mind, threatening to suppress hostile thoughts.

-Spending 1 sorcery point to subtle cast Calm Emotions at a point 30ft back the way the group came/where Paul had mentioned the followers came from.
(OOC: Not.. sure how better to describe that without a map, but hopefully the above make sense. Eitehr way, he's using Subtle Metamagic to not give away any spellcasting and catch them off guard. To resist, it would be a DC 15 Charisma save or any hostile feelings the duo might have become suppressed for 1 minute.)

The link works for me but I think it time-out somehow!

(OOC: Yes, I get the same message again, I think it only works as a live map when hosting a session at the time)

Bugger will have to come up with a Plan B

We’re going to need to continue with Theatre of the Mind in the absence of getting maps to work so what does the party want to do?

Passoveloce, after hearing Corwyn's words, assesses the situation quickly. If the room is sufficiently dark he will use Lucas to obscure himself from prying eyes and shadow step into the western alcove from whence the two figures following us have appeared (assuming it is within 60'). If there is sufficient shadow or object to hide behind (where he shadow stepped to), he will then do so. 
Hide DC15): 23

If this is not feasible, he will simply use Lucas to hide behind (using the above roll), and prepare for what comes next.

Knowing there is another dead party in the room, he is not keen on trying to quickly unlock doors before giving a thorough check for traps.

(OOC: Staying committed to subtle casting calm emotions if Passoveloce isn't able to get into the positioned he wished)

Corwyn:

Turning around from the locked door, Corwyn lifts his burning blade and looks back into the room, trying to attract attention towards himself and away from any stealthy ones, saying, “A stout locked door and lifeless bodies of the fallen—this is starting to feel like a trap, or an AMBUSH!.”

Perception:  8

OOC: Did someone take the cure wounds ring?

Torunn will inspect the locked doors and see if he can pick the locking mechanism.

Thieves Tools: 12

 (Corwyn is happy to accept the ring if no one else speaks up for it).

As the two characters following the party get within 60 feet, Corwyn and Lucas can see that one is a hobgoblin whilst the other is dwarvish - probably duegar. Lucas casts his spell as Corwyn prepares for combat. Meanwhile Passoveloce has disappeared while Paul leans on his axe idly scratching Babe between the horns. Toruun is tinkering with the door when one the hobgoblin calls out something in languages that nobody understands. Corwyn and anybody else that speaks elvish think they hear the word ‘key’ in whatever it is that the hobgoblin says. Neither the hobgoblin or the duegar respond to Corwyn’s statement. Then there is a click as Toruun managers to open the doors.

Toruun - what are you doing?

Passoveloce - you emerge about 5’ behind the hobgoblin and the duegar.  You do not think they are aware of your presence but ….?

Corwyn:

Hearing a word in Elvish, Corwyn switched to that language and asks, "Who are you and what are you doing here?"

Passoveloce stays silent and unmoving as he merges in with the shadows behind the pair. He does however observe them intently to see if he can discern their disposition towards the party.

Insight: 15

"Mind not our compatriot here. With the exception of myself, most of the others have gotten a little... lost in their roles dealing with matters abroad." Said Lucas in what would sound to everyone else to be in a tongue most familiar, and by extension most understandable to them. Because in that brief moment in which he leveled a faux admonishing glare at Corwyn soon after the elf spoke, more 'subtle' tapping into the Weave once more with nary of sign of the act. 

-Subtle Cast(1sp) Tongues on self. 
(OOC: The above mention of 'in a tongue most familiar' is just flavor)

"I assure you that the spell woven to assure the success of our mission will fade in time, and you will hear and see them as you've always had in the past." He implied cooly and with an air of authority about him. "I pray we have not disturbed your own business, and if so, perhaps you wouldn't mind a few inquiries before returning to your posts."
