Thank you to Luolang for writing the summary!
The party was making their way to Skullport. There is a rumbling, as a large wall manifests. The corridors and tunnels of the area begin to shift and form into a completely different place. The party finds themselves with Iriana and Michael alone together, with Kai and Alfine on the other side of the wall. The party tries to talk, but can’t get past the wall.
Iriana and Michael have no choice but to go forward. As the party approaches, they see a black metallic chest. Iriana tried to target it with an eldritch blast, but nothing happened. Iriana investigated the chest; she realizes it is an illusion. It is actually a small box with a rune on it. The party decides to bypass it. The party then hears the sound of an underground stream; it doesn’t sound too far away. The party approached the river and decided to head upstream. Iriana saw a grick nearby.
The party started going downstream. The party came across the site of a battle where troglodytes had been killed by drow poison. Iriana stealthed forward. She can hear sounds of battle between drow and troglodyte. The party slipped past, heading down a southern passage. They end up in Skullport.
They run into a pair of duergar along with a sobbing woman. They told the woman to go to Nightshade’s Caress, but it seemed that she had no more money. Her name is Stella, and her friends were petrified. Michael asked passerbys where Nightshade’s Caress was.
The party finds Unknown and spoke to Nightshade, acquiring 2x ointments of stone-to-flesh. They decide to help Stella Underwood to go to her friends, as Michael gets a feeling he should go there. The party heads towards the Labyrinth to take the trade route. The party walks for hours with Stella, eventually the party will be led off the trade route. They will be wandering the Labyrinth, eventually after a few more hours, Stella figured out the direction to go. The party ended up in a strange chamber, where they heard strange grunting noises. They found a badly injured half-orc and a petrified brown bear.
Stella went to go hug the half-orc and points to the brown bear. The brown bear was wildshaped into a bear when they got petrified. The half-orc is named Kruum Facesplitter. Michael healed the half-orc with healing hands, and Iriana used the ointment of stone to flesh on the brown bear. The brown bear was unpetrified and turned back into a halfling. His name was Kasdon Brambleberry, part of the adventuring group with Stella and Kruum.
Stella Underwood - Human
Kasdon Brambleberry - Halfling (Lotusden) Druid - petrified in the shape of a brown bear
Kruum Facesplitter - Half-Orc Barbarian
Michael offered to take them back to Skullport, as Stella’s group was trying to leave the Underdark. They decided to rest for the night. Michael sets up tripwire and caltrops traps.
During Iriana’s watch, she hears the sound of cackling. As she looks around, she sees a strange hyena-like humanoid shape approach. Gnolls are approaching. Iriana wakes up Michael. Michael tries to wake up Stella, but Stella screams, alerting the gnolls. The party fought an ambush of gnolls, but dealt with them. They returned to sleep.
Kasdon approaches Michael and gives him a goodberry. The three also give Iriana and Michael some items in thanks. They then begin to head back for Skullport.
As they walk back, Iriana feels vibrations in the ground. She starts looking around. Then the sight of several gnolls appear, along with a massive gnoll - (Yeenoghu, unbeknownst to the adventurers). The adventurers along with Iriana and Michael start running. Its hard for Yeenoghu to follow in some of the smaller tunnels, but it relentlessly follows along with other gnolls.
As the party runs, a 20-foot waterway cuts through the path. The stream is shallow, but there are some moss / fungi on these rocks; it could make them slippery. They manage to go past without slipping.
The party then comes across a muck pit that is slimy. Michael and Kruum got stuck, but they pulled themselves out. They continued running, but Yeenoghu was gaining on them.
As they go forward, the feet crumbles undernearth Kruum, Kasdon, and Stella's feet and they begin to fall, but Iriana casts feather fall on them to help them. They tell Iriana and Michael to keep running, as Yeenoghu seems to be chasing them. They eventually come across a large gorge, with a small side tunnel. They will need to split up to escape.
Michael tells Iriana to go down the side tunnel, and the two hug before parting. Iriana collapses the tunnel behind her and escapes. Michael activates his Radiant Soul and wings, luring Yeenoghu as he begins to fly across the gorge. He tells Yeenoghu, “Go back to the darkness!” as he slams his sword into the cave roof and channels radiant energy to cause a cave in to cut off Yeenoghu’s pursuit.
Iriana eventually ends up back in Skullport. Michael continues through the Labyrinth, until he eventually finds himself on the trade route and following a group of a duergar. Michael followed them, acting as protection in exchange for heading to civilization. He eventually ends up near Gracklstugh, making his way towards the Darklake District.
