Erven leans in to the embrace by Khessa, and gradually composes himself, surprised look on his face that all of that spilled out.  “Thank you…” he says simply, words being tough to find for the elf at the moment.  

As they find the likely entrance to the lair of the cultists and Mud asks his question, Erven steps forward and says “I can lead.  I can track and hunt, and I can stay silent and unobserved in the shadows.  I can kill with my bow, I am a sharpshooter with it.  And if things get close and dirty, I can do that too.  I am especially skilled with tracking and killing the undead, and I have a suspicion we will meet them if we follow this path.  I can heal and provide supplies….”  Erven casts goodberry and puts the 10 berries in his pouch.  “In terms of spotting their traps, I don’t have expertise in that.  But I will track them and hopefully spot them as I can easily see in the dark…”. Erven stands ready to enter with you.  

"I can try spotting traps as I too see a bit better than others while in the dark. For my skills I am a dab hand at cleaning. For combat I like to be up close and personal, though I am no meat shield. My skill set involves stabs, punches, kicks, and headbutts. I also know a thing or two about healing though I not a devout worshipper who are blessed by the gods." says Ketangu in a lower tone that is a bit above a whisper in case someone is watching them. 

The blonde arcane warrior becomes very interested when Ketangu says he can try to locate them. Khessa, having already asked Tabitha to check for any magical auras, now turns her blue eyes to the mysterious creature with the fluid shape: "In this case... would you mind trying to check for traps? As soon as we have an idea of ​​the defenses prepared by the cultists, we will be able to begin exploring with a little less danger on our part..."

"I will give it a shot" says Ketangu and he checks the entrance for traps and if there are not, he moves in and down the tunnel.

The young dark-haired man takes a look at the fallen cultist as the group passes him by, committing his appearance to memory for future use. He then let's the sister follow close, following the curious cat on her steely steed.

As the newly formed group arrives at the poorly hidden entrance, he stops and studies it while listening to the others revealing their abilities, moving closer to the entrance to have a closer inspection as the others talk. "Since we're all sharing I can tell you that I'm happy to let Erven lead this little mission. If we think an obstacle can be talked down I'm your man, and I have some tricks up my sleeve when things get rough, but I'm not one for close up encounters." He says as he carefully studies the entrance, then glancing over at the feline inventress for her confession.

Investigation to find any traps by the entrance: 15 Another roll if the tiny invisible assistant is allowed to provide help action: 14

"Fine" Khessa agrees. "Once we discover if there are traps or spells warding the area and what we can do about that, we let Erven scout ahead. I come next, ready to block eventual attackers. After me, the others follow - closer to me those who prefer to fight in melee, further away those who prefer to fight from range".

As the party prepares to enter the underground complex, a figure rushes up to them. It is a familiar one: Kit.
Ketangu notices no traps. The entrance to the hideout seems to be unguarded.

Grover, please describe how Kit catches up with the party

And, here, I hand things over to my temp DM, Dimir! Dimir, feel free to proceed with Areas N1 & N2 once the party has reintroduced Kit

Returning from escorting Valarie safely home, Kit hears whispered voices coming from an alleyway. Curious and concerned, she creeps cautiously closer to investigate...

And that's when the loud crash from a toppled stack of empty wooden boxes gets the attention of anyone who might not have already noticed her approach.

Mortified by her clumsiness, Kit starts to back out of the alleyway and away from the crowd of mysterious figures with raised hands.

"Sorry. I got lost. I don't want any trouble."

"Wondered where you went there girl? Thought you and the other pretty lady might have enjoyed each other's company but here you are." The dark-haired young man says with a teasing smile as he steps back from the untrapped entrance to the morbid cultist hideout. "If you want no trouble you might want to go home girl, but a little trouble will only be exciting I can assure you, so please join us for a little trouble as we track down the sinister cult that had this poor woman's brave brother murdered only moments ago. You look like you can handle a blade so perhaps you should follow the dastarbly handsome elf up front." He suggests with a teasing smile, ready to fall in line as Erven takes the lead into the secret lair of the cult.

Meanwhile a tiny invisible flying figure sneaks ahead and peeks for threats to warn our intrepid heroes of any amubushes set for them.

"Well, now you're not lost anymore... you've found us!" Khessa winks, patting Kit on the shoulder "Welcome back".

She prepares to enter shortly after Erven, leaving him a little distance so as not to nullify his stealth - but ready to reach him quickly in case of problems.

Kit looks around at the group, seeing more than a few familiar faces and at least one new one.

"You...again? Did you find the Hag? It sounded like she was attacking someone else so I figured it was time to get Valarie out of there. What's all this about a cult?"

As she speaks she pays special attention to dark-haired young man, not entirely sure if he's mocking her.

"No hag, just a wicked murderous cult that apparently hails the undead, the rest is for us to find out if you're interested in some heroics?" The dark-haired young man says.

Kit considers the motley group carefully. A trio of humans and a Wood Elf was reasonable enough but a Tabaxi, a Dragonborn, and an...Ooze? It sounded like the opening of a joke her father might tell in private among his friends. And to run into them all again here randomly after leaving the bar? Searching down a dark alley for an undead cult to avenged a murder?

Kit has never been religiously inclined so the idea of divine intervention never even flits past her mind.

Which meant that, to her, this whole thing was an incredible coincidence or some kind of elaborate con.

Either way, she was too intrigued not to find out.

She flashes a wry smile at the dark-haired man and places a hand lightly on the hilt of her sword.

"What are we waiting for?"

(Forgot. I finally have a decent pic for Kit)

Erven jumps slightly with a start, tension wound up like a string inside of him when he hears the wooden crates crash, but calms down and relaxes when he sees the warrior that he saw in the Dancing Donkey, approaching in a manner to be friendly and helpful to their cause.  “Shhh!” he says needlessly, with a smile and a finger to his lips, as they gather and make ready to enter.  He turns to look at Khessa, pulling out something from his pack, a horn that he has.  “This horn… is magical.  I can blow it so that only you hear it.  If you hear the sound of a horn in your ears but no one else hears it… come running, okay?”  Erven nods, and packs it away.  He pulls his cloak over himself, sticking to the shadows, he becomes very hard to see.  And he moves forward….

Erven steps forward into the shadows, becoming invisible to even those with darkvision, he stops just inside listening, and looking for movement, then examining the floor for traps.  He moves slowly initially, steping back every 20 feet or so and whispering for those behind to move forward.

Upon reaching the decision to enter into the lair of a cult dedicated to an unknown god, the unlikely group of adventurers take a deep breath to muster their resolve before entering into the bowels of the lair. The darkness of the gaping pit of the tunnel almost seems to engulf you like a predatory beast as you each descend one by one into the cult's lair. The stone walls of the tunnel glisten with moisture in the faint moonlight that manages to seep into the entrance of the tunnel, though beyond a few feet, darkness reigns supreme. Sloping downward at a gentle decline, the tunnel banks suddenly to the left for about twenty feet before opening up into a center chamber. As you venture down the tunnel, the darkness and humidity making you feel much like your traveling down the throat of some ancient beast.

With the keen senses of those up front, no traps are detected as the group one by one enters into a small chamber. Here, the smell of rotting sewage, foul water, and decay hang heavy in the damp air. Suddenly, a rather rustic looking sconce set into the wall near the tunnel flickers with sickly green flame, bathing the chamber with its unnatural light. Bathed in the unnatural green hue, you see wood and stone debris from collapsed buildings litter the area. Brackish water floods nearly half of the chamber, getting deeper toward a dark tunnel to the west. The sound of lapping water fills the otherwise silent chamber with a gentle, yet foreboding ambiance. Both Kentagu and Erven spot some sort of gap behind some rubble in the southeast corner of the tunnel. Maybe it was some sort of crawlspace? You'd have to clear the rubble away first before you could come to any conclusion.

His snout wrinkling in disgust at the odor wafting from the low pool of murky water, Mud says, "These cultists really should build their hideout someplace a little more classy. This place is nasty." 

Kentagu

Tabitha has been lost in thought, writing in her journal when she looks up and sees everyone heading in. Oh, and a new person has joined. She must start paying more attention. She quickly hurries to follow everyone else into the hideout. "Eww, this is not nice. The water better not rust Lance, I can fix him if I need to but I don't think it is very nice for him. I will need to wash my feet after this. And the rest of you will probably make do with a bath" at the mention of baths, she shivers. She isn't as disgusted by them as she is by this water, but it is still water at the end of the day. 

"I suppose you can't be too picky when you want to set up your secret sinister death cult, but we should definitely have a word with them about their choice of venue." The dark-haired young man says with a brief grin as he scans the greenlit foul-smelling chamber. It wasn't his first time in the sewers of Neverwinter but he always hoped it would be the last. It was a small consolation that the stink would soon not be felt, on the other hand he would definitely need to give his attire a good cleaning once he made it back up. "So, Kevori, was there anything more at all you could tell us about what to expect down here?" He quietly asks the sister.

Khessa remains in a central position, possibly between her companions and the visible passages, ready to spring into action at any moment.

Not having noticed the south-east alternative, she fixes her gaze on the only new route, the one to the west: "It doesn't seem appealing at all to me, as a passage... Is it possible that the cultists regularly get dirty and wet every time entering or leaving their base?” she muses aloud "I suspect that there may be some secret passage - or at least something that we have missed".

It's clear from the tone of her voice that the tall adventuress isn't fussy... for her, used to helping her family with the work in the fields since she was little, including cleaning the animals or spreading manure as fertilizer, the western route is not very attractive - but can be taken without problems . She is however perplexed, because it appears to her to be at least... inconvenient, as usual access point to the base, from the point of view of the supposed occupants.
