(Done) as Margaret closes her eyes and goes into Marco's senses, the bird/Margaret flies a short distance away, and plops down at an intersection, they can see up the northern hallway 120ft into a cavern, and the beginnings, of a underground lake.                                                                                                 

To the east they can see, variable intersections. And a little further to the north, (15ft) of Marco/Margaret, an intersection leading west.

Meanwhile, other than the sense of touch, Margaret is unaware of what is going on, about her own body.   

Krull is watching after Margret now she is vulnerable."it's good we have Marco with us .we might be able to reach our target without bumping into more enemies like that thing." Krull says pointing at the remains of the blob.He is pretty sure Rabbit has a plan so he asks straight away "Any plans  once we face the spider?we don't know anything about him or her apart from the nickname. Weaknesses or strengths?" 

(DM: I can control Margrets token but not Marcos)
Seeing through Marcos eyes for a moment, "Well, there's a passage up ahead going to the right or we can continue north."

(Also....see 4792 for additional info)

She recalls Marco back to her, concerned that he will become some cave denizens next meal.

Try it now, you will have to ask me to turn its vision back on for when you go into Marco's senses   

"So long as not step on web, easy to jump on spider. They never expect ambush. Especially in own nest." Droop suggests while maintaining his look out, confident in the echo nature of the cave to carry his voice well enough. "A-although, might be tricky. Spiders like ceilings and dark places. Very hard to reach for Big Man, Droop think." 

Rabbit gives Krull a questioning look. "You mean the person called 'The Spider'?" She glances around a moment just to make sure he's not talking about an actual spider. "Probably just some addled wizard like Iarno." She shrugs. "You suppose he's already here inside somewhere?" 

When Margret relays what Marco has seen, she says, "I'd rather head to the right first. See if we can connect back to where we came in.  Just to get an idea of where these passages go.  Then perhaps we can come back and see about that lake."  She looks to Margret again. "Perhaps let Marco fly ahead and we'll follow?" 

"Might be.. Don't know.What makes you think is a man? He or she probably knows we are coming for him or her ..and you said he or she is a wizard eh?that makes it more difficult..I prefer dealing with swords and fists..I know how to handle those.. Magic..not so "

(I took the barriers down to the immediate north)

“Yes,” Margret sends Marco carefully to the right passage, losing focus as he slowly advances for a quick peek.  

"Well," Rabbit starts as she responds to Krull, "I think 'The Spider' seems dumb, so most likely it's a man. And I have no idea if it's a wizard. Just a guess."  She then glances to Margret, waiting for her word on the path before the continue on.

Krull nods even if the answer isn't what he was expecting.."Aye but whatever he or she is ..mage or fighter is very powerful and has a lot of influence..Fear is his or her weapon .Do you think Iarno was afraid of the spider?"

Turned Marco's vision back on, and Margrets off, I set a barrier up where your find familiar, radius ends, Margret, explore. 

Margret tunes out as she sees through her owl's eyes.
"Well, its sort of a square grid for a while, but if we turn right and go about 70feet, then turn left (north) there are stairs going into a much larger room and something maybe alive there....., maybe 4 of them, with perhaps a dead body, and ah, from Droops location, we can get to the same place in about 50 feet, going a bit north connects with the other corridor. Theres a pool of water 100 feet directly North past the right turn. It then a set of stairs, it may lead to the same large room, or maybe one to the left of the large room."

She waits for Marco to carefully explore a bit more.

"There is also something a bit to our southwest we could explore near a dead end., and....another thing in the passage just south of that, but the major room is the one with the two sets of stairs and the 4-5 beings. Other turn-offs mostly lead to dead ends."
Her awareness comes back and her breathing changes as Marco returns and lands on her shoulder.

(If you can see it on roll20, blue-drawn line will lead to the big room, and if we want we can enter from two locations. (South side of room and west).

Margret takes out a piece of paper and traces out some of what she sees.

Krull starts rubbing his temples.."Damn it woman too much information!Cause a headache you know!Why not  draw the whole thing from the beginning?" says with a hint of complaint.He then crosses his arms waiting for the rest to make a decision 

Droop is only half paying attention at best, as keeping lookout remained his primary point of concern. But in sensing at least one set eye on him, if only briefly, he'd glance back to the other party members, stare at them in blank confusion, and then simply shrug. "Big Man make good point. Less Birdy scared of going far, we just sit tight here and wait. No harm no foul, ye?" He asks. "Or just go water way, seeing as Spider not in big room, yea? Droop feeling thirsty, so good place to get drink!" 

"If there are possible foes, that's where we should go first," Rabbit says. "Not sure how well I could sneak up with the smell. But maybe going from two directions will help."  She glances to Margret. "No clue as to what the 'something that may be alive' might be?  I fear the dead body might be another brother."  She pauses to let others comment, then asks. "Shall we proceed? How should we split up?" 

The boom occurs, three more times, as the group decides which way to go, the breeze, blows with the sound, as if the cave is living, breathing thing, water drips from the ceiling like saliva, insects travel here and there on their own business.

Marco/Margaret's passive perception noted medium sized things, moving, and a stench, coming from the largest room she drew.

Margret roll Marco's stealth, with advantage

(21 stealth for Marco).

"We best get moving, I suggest toward the multiple targets in the large room, and....And since I'm not certain if the staircase by the pool goes into the large room, either look there first, or just head in staircase to our north east."

"I'll lead the way."

(OOC: we either explore the pool room and see where the stairs lead (North on my pic, or we follow the red line to the other staircase, and likely enter combat immediately)

"If we head towards the big room we need to take them by surprise..toss some fire could do the trick..Droop do you have any liquor?" 

Krull searches his backpack .. Honour..the word rings in his head..He understands though that sometimes you have to abandon it to gain results.He carries on "If we say we are here( means  announce their  presence)  they might bring more (reinforcements) and we rather not do that"

Droop goes from blinking and looking incredulous at Rabbit to regarding the party with a look that said 'Did you guys just hear that, or am a wrong", and then finally facepalming at Krull's request for liquor. "No. Droop not have that. Othewise, Droop drink all of it right now after hearing what Droop heard." He frankly admits with an exasperated look about him. He then sighs and shakes his head. "Droop no care. He follow whichever way."
