The Deepmarket is an adventure for four PCs of 3rd level. The Deepmarket is written for Pathfinder RPG but could be transplanted into another campaign setting. This short adventure provides a flavorful segue for any Pathfinder campaign.

The Deepmarket

By Jenny Jarzabski
Playtested by Evan Willis and Jon Cary

Zyrinix was always considered different by dark folk standards. While most dark stalkers are content to dwell in their underground cities, employing the lesser dark creepers and slaves of other races to do their bidding, Zyrinix had dreams of travel, trade, and collecting riches for himself. He would take anyone’s gold, whether they were a drow priestess shopping for poisons or a lost surface-dweller trying to survive in the Darklands.

Two decades ago, Zyrinix “adopted” a vegepygmy chieftain who possessed a level of intelligence unusual for her race. In reality, he captured the creature and forced her to confine her russet mold infestation to a jar worn on a cord around her neck. He taught her the ways of trade and crafting poisons, and she taught him the strange language of her kind.

Together, the two founded the Deepmarket, a traveling hub for potions, poisons, and curiosities. The duo found that setting up shop in Nar’Voth’s surface-connected caves and tunnels brought the best business. Curious surface-dwellers heard of the Deepmarket through whispered rumors, and were willing to part with copious amounts of coin for reagents and items rarely seen above ground.

Today the Deepmarket travels around Golarion, setting up shop in caves, mines, and even sewers. The market typically stays in a locale for a few days before moving on. Those in the know need only speak the passphrase to gain entry past the dark creeper guards and into the strange trading post.

PCs who visit the Deepmarket must speak the passphrase (“The golden light of dawn”) or deal with ghast guards and a trapped gate. PCs are greeted by an array of goods for sale, including potions, poisons, slaves, and reagents. PCs who seek a specific item or service must negotiate with Zyrinix and Clicker. When PCs try to leave the market, they are ambushed by a derro slave trader hoping to sell these fine specimens deeper in the Darklands.

Adventure Hooks
PCs might visit the Deepmarket for a variety of reasons. Perhaps a local merchant asked for a rare ingredient, such as brain mold spores, that can only be bought in the Deepmarket. PCs may have information about an explorer who delved too far into the Darklands and left behind a journal complete with detailed maps that found its way to the Deepmarket stalls.

Alternatively, a devious GM could use this adventure to transition into a Darklands campaign, pitting low-level characters against challenging combats they are sure to lose. If the GM chooses to use the Deepmarket for this purpose, enemy combatants should deal nonlethal damage and/or heal PCs as they fall, planning to revive them once safely caged.

Whatever the case, the PC’s current city is unknowingly playing host to the Deepmarket. A Knowledge (Local) or Diplomacy check (DC 20) reveals the market’s current location to be in a nearby cave or sewer.

PCs may discover the following information about the Deepmarket.
Diplomacy or Knowledge (Local)
10+ The Deepmarket is a traveling cadre of merchants, mostly native to the Darklands, who sell rare and sometimes illicit goods and services to surface folk.
15+ To gain entry to the Deepmarket, one must speak the words, “The golden light of dawn.”
20+ Some surface-dwellers who seek the Deepmarket never return. Survivors claim the dark stalker who runs the Deepmarket occasionally captures his would-be patrons to sell as slaves in the Darklands.
25+ Zyrinix, the dark stalker who founded the Deepmarket, has a pet vegepygmy chieftain who is a skilled alchemist in addition to being infected with russet mold.

A. To Market, to Market
Wherever their starting point, a successful DC 15 Knowledge (Geography) or Survival check leads PCs through the sewers or cave system to a cavernous tunnel (20 feet high and 10 feet wide) that leads farther into the earth. In 300 feet the tunnel narrows to an area only 10 feet wide. Further ingress is blocked by two wooden poles bearing a cloth divider. The area beyond the gate is a shallow cave that measures 40 feet wide and 80 feet long. The cave is completely dry. The cave is largely packed with carts and stalls (A2). Toward the back of the cave a small tunnel (Perception DC 20) leads deeper into the Darklands.  The ceiling throughout this cave is 30 feet high. The area is in complete darkness. Any attempt to shed light on the cave through magical or mundane means will draw the hostile stares and hisses of both merchants and customers.

Though in reality the Deepmarket is a merchant caravan, losing and gaining members as the seasons change, treat the Deepmarket as a large town (Pathfinder RPG GameMastery Guide 207) for the purpose of buying and selling gear and magic items.

The Deepmarket’s “population” of sellers and patrons fluctuates, but is generally 30% dark folk, 20% duergar, 20% svirfneblin, 15% ghoul, 5% drow, and 10% other.

A1. The Gate (CR 5)
Two sharpened stakes twice as tall as a human plunge into the soil ten feet apart. A tattered black cloth hangs from the poles, shielding whatever lies beyond from view. Two pale, gaunt humanoids bar access to the makeshift gateway.

Zyrinix has gained the loyalty of many creatures over the years. The ghasts that guard the entry to the Deepmarket are some of his favorites. Their intelligence coupled with their ability to paralyze and sicken hostile parties makes them excellent gatekeepers.

The ghasts who stand guard here have already supped on a meal of fresh entrails, provided as payment for their talents by Zyrinix. They begin as indifferent to the PCs, and as long as the correct passphrase is spoken they will not attack. Regardless of the ghasts’ intent, PCs must still deal with the roiling stench of these creatures.

As PCs approach, one of the ghasts croaks, “What is the most terrible sight to behold?”

Creatures: Three ghasts employed by Zyrinix guard the entrance to the Deepmarket.

Traps: If PCs fight the ghasts, they must deal with the trap placed on the makeshift gate.

Ghast (2) CR 2
XP 600 each
hp 17 each (Pathfinder RPG Bestiary 146)

Poisoned Dart Trap CR 1
XP 400
Type mechanical; Perception DC 20; Disable Device DC 20
Trigger touch; Reset none
Effect Atk +10 ranged (poison dart; 1d3 plus black smear)

Development: When PCs bypass the guards, they may enter the Deepmarket stalls.

A2. The Stalls (CR 5 or CR 8)
Use GameMastery Map Pack: Market Place for this area.

Hooded figures mill about a wide alley surrounded by carts and stalls. A cacophony of voices fills the air, promoting wares and bartering in myriad languages. The carts are laden with rows of grotesque specimens in jars, vials of murky liquids, and bundles of unrecognizable plant life. Beyond the crowd of merchants, tents shelter cages and pens inhabited by a variety of humanoids and animals. Several small wagons circle the tents. Horse-sized beetles tethered there graze on heaps of fungus.

PCs who succeed a Diplomacy check (DC 15) are pointed to Zyrinix’s stall. Zyrinix greets the PCs as follows: “Welcome, surface-dwellers. How may I serve you?” Clicker remains silent, eyeing PCs with interest. If they speak to her in Undercommon, she responds in a language of clicks, whistles, and guttural syllables, which Zyrinix quickly translates.

Zyrinix is willing to sell any items or services desired by the PCs, but at twice the usual price. A successful DC 20 Diplomacy check convinces Zyrix to sell the items for only 150% regular price.

If the PCs seek information about the Darklands, other customers, or the city in which the Deepmarket currently resides, a DC 30 Diplomacy check is needed to garner this information (a bribe worth at least 200 gold reduces the DC to 25).

The following are questions PCs might ask Zyrinix.
Who are you? “Zyrinix, at your service. My moldy associate here is Clicker. I would tell you her true name, but I doubt you could pronounce it. We are purveyors of the finest goods and services from beneath the earth.”
Do you have (a specific item)? “Ah, of course, my sunburnt friends. I have whatever you need if you’re willing to pay the price.”
Do you sell slaves here? “I prefer to call them unpaid laborers. You see, there’s quite a demand for workers down here, and my supply reflects that need.”

Creatures: The dark stalker Zyrinix and his vegepygmy associate, Clicker, are conducting business as usual in the main stall.

A new save can be attempted each round to stop the growth of the spores. The growth can be halted by remove disease and similar effects. Exposure to sunlight also halts the growth of russet mold spores. After 24 hours, a fully grown vegepygmy bursts from the body of any creature slain by russet mold. (Include page number)

Special Abilities
Death Throes (Su) When a dark stalker is slain, its body combusts in a flash of white-hot flame. This acts like a fireball that deal 3d6 points of fire damage to all creatures within a 20-foot-radius burst. A DC 15 Reflex save halves this damage. A dark stalker’s gear and treasure are unaffected by this explosion. This save is Constitution-based.
Poison Use (Ex) Dark stalkers are skilled in the use of poison and never risk accidentally poisoning themselves. Like their diminutive kin, the dark creepers, dark stalkers use black poison on their weapons and generally carry six doses on them.
Black Smear—injury; save Fort DC 15; frequency 1/round for 6 rounds; effect 1d2 Str; cure 1 save. The poison DC is Constitution-based.
See in Darkness (Su) A dark stalker can see perfectly in darkness of any kind, including that created by deeper darkness.

Development: If PCs fight and defeat the dark creepers, Zyrinix returns and offers the desired item(s) at a 50% discount as a truce. If PCs fight and defeat Zyrinix, chaos envelops the market as slaves attempt to break free, patrons run for the nearest exit, and more guards descend upon the group. PCs have 1d4 minutes to flee before the derro slavemaster and his minions from area B attack.

A3. No Exit (CR 4)
Use GameMastery Map Pack: Market Place for this area.

A successful Perception check (DC 25) reveals the mouth of a narrow tunnel (5 feet wide by 6 feet high), but this tunnel only leads further underground. PCs must exit the way they came, through the ghast-guarded gateway.

Unbeknownst to PCs, Zyrinix calculated that selling his clients into slavery would be most beneficial. Right after they left his stall, Zyrinix ordered his derro colleague to subdue the PCs and take back any goods they acquired.

Creatures: A derro slavemaster and his pet giant black widow spider stalk the PCs.

Derro CR 3
XP 800
hp 25 (Pathfinder RPG Bestiary 70)
Before Combat The derro casts darkness and tries to snipe PCs with its poisoned crossbow bolts.
During Combat The derro orders its spider pet into melee and attacks with its crossbow. If cornered, the derro fights with its aklys.
Morale The crazed derro fights to the death.

Young Giant Black Widow Spider CR 2
XP 600
hp 37 (Pathfinder RPG Bestiary 2 256)
Before Combat The giant black widow waits for its master’s command to web PCs.
During Combat The giant black widow first uses its web to trap PCs, then charges into melee.

If the PCs manage to escape the Deepmarket, they return with rare items and a newfound respect for the denizens of the Darklands. If Zyrinix lives, the PCs may have acquired a new enemy.

If the PCs are defeated by the deep merchants, however, they wake up a few hours later in cages. Will the captives manage to escape Zyrinix’s clutches, or will they be traded to drow or duergar and begin a new life of enslavement in a sunless land? The possibilities are endless.
