As Droop, makes his statement, a very dour looking dwarf, Gundren comes up the passageway to the south of him, Gundren looks like he is about to say something in his normal 'loud' way.  

Krull will make a shush with his free hand and will point towards the North "talk loud and we ll be dead" 

Krull roll persuasion. 

(11 but with the stubbornness a dwarf possess I find that difficult to convince him)

Margret regains her composure. "This way if we want to exit." She whispers.

Gundren holds his tongue, a few more stirges, fly past the flame skull up the northern passage, prompting, the skull to chase after, the light lessons in the eastern part of the cavern, then, other than a few 'flashes', grows dark again.     

In mistaking Krull's target for the shush, Droop immediately clapped his hands over his mouth and looked up apologetically at the goliath. And with Gundren actually staying quiet the goblin's sense of guilt is only reinforced in the moment. So much so, in fact, that he rapidly nodded in response to Margret, then stepped aside still holding his hands over his mouth and meaning to follow. It's only when he's moving to take up the rear that he finally spies Gundren and looks about ready to leap up and yell in surprise....

....

Unless of course someone informs him well beforehand. In which case, the goblin's reaction is more of a mild look of surprise, before he then approaches the dwarf and pats him on the shoulder. All while wearing a look as if he's about to pass along some grim news. 

Assuming the rest of the group is still headed out of the cave, Rabbit follows along.  She figures it's better to regroup than to try and get the group back together here.  

Once they our outside of the cave Krull will put down gently Margret saying as he does that "We didn't find Spider but we found one of Gundren's brother.Now what?! We still have to kill the spider and a dragon"

He takes out his waterskin and drinks a bit and then he says narrowing his eyes"I prefer not to go in there again unless we have to(means necessary)"

Gundren looks taken aback, by the notion of leaving "I've 'lost' one brother, I won't loose 'another'! What did this thing look like?" 

"Yes," Rabbit says firmly, looking mostly to Margret. "Given your massive panic I presume you must know what it was that was in there."  She looks around at the rest of the group. "I'm not sure why we even make out here if we're going to run off from every danger. But I'd like to know what thing is. Perhaps we can find a way to fight it." 

"Running?Who is running? Remember Glasstaff?or The undead Helga and the others..the orcs?we Fought all of them didn't we?"

He takes a deep breath and finishes his sentence"Our job was to find master Gundren and we did..we looked for his brothers..we found one .Now last job is to kill the spider.."

Rabbit stares at Krull. "You were the one hauling Margret out of there as fast as you could! I'm not sure why you're so eager to kill this Spider. But as you said, we still haven't found Gundren's other brother!"  She again looks to Marget. "I presume you know what that thing is - hovering glowing skull thing?  Care to explain?  There must be a way to eliminate it." 

Krull calmly replies "Only cause I had to save her for that thing..she ran towards it..I don't think she knows how to kill it..Do we have an idea what it is? floating bone head with shooting fires?" he sighs in defeat"Fine we ll kill it but I am doing it for you Rabbit "

Margret grimaces, “I don’t know, but usually when you see a floating skull shooting stuff out of its eyes…it’s time to go. Now it’s slow and you can see it glowing from fare and it may be slow…but my guess is a Lich.”

I think we can get to the pool of water pretty easily and the lower area maybe.”

Gundren thinks upon the groups words, "Did it have 'Green flames' wreathed around it?"   

(OOC: I assume at this point, though no-minis have been moved on the map that the group have at least made it back to the entrance of Wave Echo Cave, if not just outside as per Baldur's post here without an issue. But, DM can feel free to correct me on this later!)

Droop watches the heated exchange nervously while occasionally shooting a glance back at the darkness of the cave. "Soooo.... we go back in? Really? Even with Lich maybe roaming about?" He warily asks, before then bowing his head. "Hmm... Not very wise even if go other way, but.... guess Lich can't be everywhere in cave. And, eh... we see it coming long before it sees us if lucky enough." He looks up again to the party. "B-but you all sure want in?"

Krull looks at Gundren puzzled by his question "Have you seen a similar thing ?heard stories?" He thinks of the dwarf's brothers ..then turns his attention again to the group"IF his other brother is here what are the chances to be alive? with those undead things and that glowing skull?"

('Your token' is where 'you are at' in the caves or corridors, nobody has moved, Gundren and the group are still in the same passageway, you can't of been looking at Gundren's, dead brother, who is 'buried' now anyway. )

As you stand in one of the southern corridors to the Dinning Cavern, Gundren looks perturbed at his question being answered/unanswered, with a question, even more so at the thought of his other brother, being dead,

"I've seen many 'things', in my travels, answer my question, please. Did it have a green flame around it?"    

(I've given you the picture of it, on Discord)

Krull points at Margret "She can tell you master dwarf more than me .All I can tell you is it's had a crazy laugh and it has magic"
