You are not sure which direction the creature went. North through a smaller tunnel or to the east along the main tunnel. As you get to this branch point you also realize you can not see anything more than a few feet in front of you. The mine is completely dark and you have out run your light source... what do you do?

Everyone can post thier turns when they are ready.

Pardot, slow as he is, dashes after Klin.

Triäsa nods wearily to Ludolf, "I am fine. We should follow Klin and make sure he does not get in any trouble." She will use DASH to head after the others. (Move 60 ft)

"This is madness, we are running headlong into another ambush." Ludolf grumbles but tries to follow close to Triäsa.
Perception: 17

Daventry sprints to keep up with Klin, bringing her light and trying to help track down the creature. She offers the blade to the monk, more importantly with its source of light.

Move and Dash: 60' to Klin

Item Interaction: Hand Blade to Klin (if he wants to take it)

Thought about burning an Expeditious Retreat but she's a crappy tracker at the moment...

"Well you are certainly cheery," Triäsa quips flatly to Ludolf. "Whatever the case, I am not letting Klin run off by himself." 

"Yes, alright, obviously we must come to his aid." Ludolf answers as he tries to keep up with Triäsa.

Klin waits for everyone to catch up to him at the intersection and for the light to return. He then heads into the smaller northern passageway. After a few moments of walking find this tunnel takes a few twists and turns and progressively narrows before ending abruptly. Klin does not see any evidence of the creature. The tunnel is a dead end.

(I am back and posting more consistently I will get you all an up to date map as soon as I can)

"Watch your language there Klin, what would your order say?" Ludolf says with a smirk. "Don't worry about it though Klin, we will find their nest somwhere in here, let's stick together now though. Daventry, you'd better take point again, whereto next?"

"Well, if this is a dead end then we try the other direction?" Triäsa says. "Or are we missing something?"

Daventry takes back her blade from the monk. "We're in his territory now, Klin. Wouldn't expect him to be easy to find... you did good chasing after him. Must've gone down the other passage, or teleported again."

She returns to the other passage, where the creature must have gone instead, and cautiously continues exploring.

Perception: 14

Chasing after, Pardot catches up, panting a bit as he catches his breath he calms himself and looks around, aware that the creature could be anywhere. He says, “We also managed to hit it a couple times. It will likely have ran off to lick its wounds. Keep your eyes open.”

You all back out of this long dead end passage to the intersection and start down the north tunnel. After a short while you reach an area of the cave that suffered the tragic collapse you learned about in the books. Rubble litters the ground and you do not see an easy way to continue in this direction. Just to the south of the collapsed passage you find another opening in the rock that leads into yet another corridor.

Pardot notices this new opening is very different than the tunnels you have come through. The opening of this tunnel is nearly circular. Black moss covers the walls, floor, and ceiling of the tunnel as far as you can see. Within this tunnel are several branches, all of them covered in the same black moss. The walls of this tunnel underneath the moss are barely visible but appear to be completely smooth and not the rough dug out walls of the previous caverns. Pardot also notes the ground is littered by footsteps and tracks of clawed creatures. It is impossible to say how many but you would assume more than one. You also see drag marks on the ground. All of the tracks appear to lead straight through to the southeast.

Map:

Triäsa will stop for just a moment and take a look at the moss to see if she can recall anything about similar moss.  (Nature: 22)

"Be careful with that Triäsa. Hm, what kind of moss could this be." Ludolf says as he stops by Triäsa and tries to help her figure out what kind of moss she is looking at.
(Help action given :-)

"It appears we may have found their nest." Pardot says, indicating the tracks on the ground, clearly afraid of what they're about to encounter.

 (Not sure what to do with this - if it had been given before I rolled the result would be the same.  Better to roll it for yourself.) 

(Thought you could just roll again as if help was given but I forgot Triäsa has disadvantage. Ludolf Nature regarding moss: 23 )

"Strange, must be a very unusual kind of moss." Ludolf muttters.
