Rill's Mouth Mines

Located a little over an hour and half to the east of Alfield and north of the Rillway Road, this old, abandoned mine was the lair from which the gnolls coordinated their attack on Alfield. The lair's entrance was located among a series of large, rolling hills, topped with broken shale, and surrounded by vibrant green grasses and tall weeds that varied from knee to chest height.

Mineshaft Yard
In a barren valley of rock and dirt, this yard contained large, wooden pan tables, broken boxes, pickaxes, the remnants of some rusted lanterns, and the three carts. The entrance was covered in a 12x12-foot blanket of interwoven grasses to cover it over.

Abandoned Shed
Around the corner, hidden among the cluster of hills above the mine, was an old shed that had long been abandoned and locked up.

Mine Entrance
As well as the wooden support structure of the interior, the mine shaft contained a partial barricade made up of piles of broken furniture, dry-rotted pickaxe handles, and wooden beams that were shattered and jammed into each other. Flanking each side of the entrance way, there was only around a three-foot-wide gap that acted as a path into the mine. This shaft was around 35 feet long and had only a faint amount of light that bled in from the entrance, beyond which it quickly became pitch black.

Common Area
Forty feet into the mine, the shaft widened into a more open area with sloped ceilings. The space was around 35 feet across, widening further to around 45–50 feet towards the back of the chamber, before descending down into two different pathways.

Both of these shafts had wooden frames for support and curved in opposite directions downward at a steady 45-degree angle. Neither tunnel shows signs of change in air current or temperature. Both of these passages seemed to contain equal amounts of footprints and traffic.

This chamber had a handful of tables, some chairs, sacks of mildewed rice grain, and dry-rotted burlap bags of supplies, strewn about. Additionally, there was an untapped ale and water barrel, a half-full hooded lantern that was partially rusted over, a crowbar, and a slightly rotted sledgehammer. On a small ladder there layed a lightweight rod, approximately the size of a small rung, that had a waxed twine hanging from one end a "Boom-Boom Stick".

Trap
Stretched across the opening of the shaft into this chamber there was a rope, which was connected to a large log affixed to the ceiling, set as a swinging trap against intruders.

Left Passage
Descending and curving downward about 15–20 feet, this shaft rapidly curved to the left and then to the right for a distance of at least 25 feet. There were no traps in this passage.

Right Passage
This passage curved down to the right and there appeared to be a slight depression on the right side of the shaft. In this depression, there was a three and a half foot wide pit that was concealed by a piece of burlap sack. The pit trap takes up only a part of the passage, which was about 10 feet wide. From this trap, this passage continues down in a spiral-like curve for another 40 feet. The tunnel continues for another 150 feet before it slowly levels out.

Ritual Altar Chamber
This chamber was long and had multiple levels, what once may have looked like a solid mining vein had become strewn with bones and flayed skin that was pinned to the rock walls with scavenged nails. Blood was spattered across them with intent, and a painted jagged smile of sharp teeth adorned four of these flayed hides. A faint source of light in the center platform of this chamber flickers from a small stone altar holding a cluster of candles. The altar had one of these marked, flayed skins stretched over it, as well as several glistening hearts, which were used in a ritual to Yeenoghu.

In this chamber a medicinal supplies chest could be found, the contents of this chest were:
 * 2 healer's kits
 * disinfectant herbs and fungi (enough for two uses)
 * When applied topically, the herbs and fungi could remove poisons if quickly applied to the wound that was poisoned.
 * a small, leather hand pack that contained 4 glass vials
 * 3 vials were shattered, and the last vial contained a greater healing potion.

Y-Intersection
The shaft beyond the altar chamber curved to the right in a wide spiral before eventually snaking a bit, then sharply turning to the right. It straightend out, and the shaft emerges into a chamber of mixed natural rock walls and simple stonework. Acting as a second common room, two other shafts, heading to the left and right, marked this chamber as a Y-intersection.

Breaking the open space, two thick, natural pillars of rock stood as load-bearing portions of the chamber, while a crumpled section of the floor dropped into a pit below. This hole was around 50–60 feet deep, and it seems to have been an intentionally created well that had since seen disuse.

Similar to the first common area, this chamber contained tables and stools strewn about the area, as well as crates, pickaxes, shovels, and a variety of tools. Most things of worth had been either ravaged or taken, though on the edge of this chamber was an overturned box containing a "Boom-Boom Stick".

Right Passage
While the Mighty Nein party was moving through the gnoll lair, a loud boom shook the interior of the chamber, causing dust and rocks to fall from the ceiling. A cloud of dust and smoke came billowing out of the right passage, followed shortly by the emergence of Shakäste. Upon later inspection, this passage had collapsed and was no longer usable.

Left Passage
Along this branch, there were two closed doors. It continued deeper into the mine at a moderate grade for about 60 to 70 feet, before it levels off and turns upward for another 20 to 30 feet leading to stairs.

Prisoner Cells
The left passage contained latched doors prison cells. Behind the doors there was a strong smell of decay emerging from four dead bodies that were in pieces and pushed to the back of the room.

Stair Passage
Other than the large, 40-foot deep pit in the upper portion of this tunnel where part of the floor had collapsed, this passage was marked by rough stairs that rise for about 6 feet.

These stairs lead to a short tunnel that sharply curved to the left toward a large 8- to 10-foot wide archway, where a set of double doors seemed to have once been but had long since been broken off their hinges. Beyond this broken doorway, the tunnel grows rougher and continues to snake for 100 feet through 10- to 15-foot wide tunnels, before opening up.

The deeper down this passage, the more musky smell that resembled a faint mixture of urine and citrus replaces the general smell of decaying earth and dust that permeate the remainder of the mine.

Last Chamber
Opening up to a large rocky alcove, this chamber was filled with stalactites, which hang from an uneven ceiling that ranged from 15 to 20 feet above the floor. A rough slope descends from the immediate entrance of this tunnel and hit a short wall before rising past it to a small platform at about 70 to 80 feet in, where this chamber and the mine ended.

Marked by signs of abandonment, with broken digging equipment lying in the corners of this chamber and walls scarred by pick marks, this chamber appeared to have been the deepest portion the miners had dug to before having given up hope when the veins became scarce.

History
After the attack on Alfield the gnoll where smart and cautious of being followed, and they hid their lair's entrance by deliberately sweeping and dusting their tracks around the mineshaft yard with dirt. To further hide the location of the entrance, on an eastern hill within this valley, the gnolls had created a 12×12-foot blanket of interwoven grasses to cover it over.

When the Mighty Nein followed the Gnolls to their lair they found three carts that the gnolls had used to haul captives and spoils back to their lair from Alfield in the mineshaft yard. Gathered around and licking the dried blood splatter that had soaked into the wood of the carts were three hyenas guard dogs.

In the Common Area Nott failed to notice a trap and sprung it, which caused the log to loudly slam against the rock wall of the shaft and thus alerted the gnolls deeper in the mine. After defeating two gnolls the Jester find a search the room and found a "Boom-Boom Stick", sledgehammer.

Nott partially explores the left passage and found no traps, so the party chose to explore the right passage instead, with the expectation that more important sections of the gnoll lair would be trapped.

When they enter the Ritual Altar Chamber there were six gnolls gathered around the altar, along with a Priest to Yeenoghu they were conducting a ceremony to Yeenoghu, the priest placed several hearts onto an altar within the lair, then gave small, muffled barks and yipping sounds. After saying a prayer in broken common, the gnolls around them yipped in unison, then tore into and devoured the hearts. This priest thought that the manticore was a boon from Yeenoghu, and that by feeding and growing it, the manticore would provide strength to the pack and thus more meat and power in the future.

After the ritual to Yeenoghu, the priest figure leaves, along with two of the gnolls and the now-visible pack leader. They kill two gnolls before the creatures have a chance to react. When the remainder do react, two hyenas were immediately killed by Fjord's Armor of Agathys. Fjord and Molly carve through a third gnoll while Jester and Beau take out the fourth. Molly and Fjord kill the last two hyenas as they were attempting to flee. Nott uses Hideous Laughter to prevent the last gnoll from leaving the room before finishing it off with her short sword. The party find the Medicinal supplies chest in this room.

After hearing a muffled *BOOM!* in the distance, what seemed to be some sort of low vocalization, some cackling, and then eventually the scream of a woman saying, 'No, my baby!', they began to run and give chade.

The party follow the mineshaft tunnel downwards towards the woman's voice they had heard. They eventually find a second large chamber containing two hyenas, a skeletal gnoll, and two regular gnolls bickering over a small human child. An explosion from nearby makes the group pause before Nott, Fjord, Jester, and Molly initiate an ambush. Just as they were firing off their first attacks, a new figure enters the room: the cleric Shakäste, who had also come to help rescue villagers.

Together, they investigate the room. Alongside another “Boom-Boom Stick and a number of bodies they find a woman, Herma, who turns out to be the mother of the young boy, Jules; and a half-elven man, Petrov. They bring both the living and seven of the dead back to the surface, to where Shakäste had a shelter with four more survivors.

Shakäste sends his familiar, a hummingbird called the Duchess, ahead to scout the tunnel beyond the second chamber. Learning that there were more gnolls, Nott and Fjord take point, sneaking ahead. He and Nott kill it quickly, but not before it can signal the rest of its pack.

Three more gnolls come to investigate, prompting another scuffle. They were shortly joined by their pack leader, which charges ahead to kick Beau into a well in the floor. Shakäste holds the leader at bay with so that Jester and Nott can take him down. Beau climbs out of the well. With the largest threat eliminated, the remaining gnolls go down quickly. Jester fond 13 gold and tree silver pieces with a two-handed glaive on the gnoll pack lord.

The next, and final, chamber of the mines contained two bound, human captives and some manner of humanoid priest wearing gnoll bones and a mother manticore and her newborn cub. The manticore consumes the human captive before anything can be done.

Nott tries to sneak in and free the captives, but before Nott can finish untying the captives the manticore sees them entering the cavern, and combat was joined. A single strike from Nott's sword kills the cub and attracts the mother's full wrath.

Beau runs in to drag Nott out of the manticore's range, although a final parting bite puts Nott unconscious. Meanwhile, the priest takes Jester out, Shakäste breaks the priest's concentration on the spell paralyzing Fjord. This allows Fjord to use a healing potion to revive Jester, who in turn revives Nott. Nott then uses Hideous Laughter to momentarily incapacitate the manticore.

While the manticore was helpless with laughter, the party focus damage on the priest. Caleb strikes the killing blow with a Fire Bolt, and the sight of the priest's burning head triggers a flood of memories that make him withdraw into himself. Shakäste lands two final blows on the badly hurt manticore, finally killing it with a bolt of radiant flame down its throat.

The Mighty Nein found the following loot in its nest:
 * A skeletal hand that had been mostly chewed through, though on a single fleshy finger it held a beautiful silver ring with a blue gem. Caleb later identified it as a Ring of Water Walking.
 * A refined and well-carved stick, which Caleb later identified as a Wand of Smiles.
 * Large chains, attached to a set of unlocked manacles. Made up of four identical loops of a little over a foot in diameter, the loops were all attached via chains to a larger loop that was about four or five feet in diameter.
