The Chained Depths: A Day's Torment

Mission: Survive a Day in the Mines

I. Introduction for the Game Master (GM)

Welcome to "The Chained Depths," the brutal opening act of The Obsidian Web campaign. Your players begin as prisoners of the Drow, enslaved within a vast mining and holding complex that feeds Narathzul's insatiable need for resources and new chattel. This session focuses on the immediate, desperate struggle for survival and escape, introducing the oppressive Drow regime and the grim reality of Narathzul's lower strata.

Players start without gear, severely disadvantaged, and must rely on their wits, observation, and emergent alliances to break free. They will immediately be put to work in the dangerous mines, experiencing firsthand the brutal, unforgiving labor expected of Drow chattel. The goal is for the players to feel the oppression, experience the dangers of mining, and through their ingenuity and exploration, discover a viable path to freedom that rewards their creative thinking.

II. Map of The Chained Depths (Area 7)

This map details the immediate mining and prison complex where the adventure begins.

• Area 1: Mine Section 1 (Commonly worked mining tunnels)
• Area 2: Mine Section 2 (Commonly worked mining tunnels)
• Area 3: Mine Section 3 (Commonly worked mining tunnels)
• Area 4: Slave Pens / Holding Cells (Where the PCs begin their captivity)
• Area 5: The Barracks (Primary housing, training, and rest area for the Drow guards within the slave pits)
• Area 6: The Lift (The main vertical shaft leading up/down from this complex to other parts of Narathzul's underworld. This is the key exit route to Narathzul.)
• Unmapped Area: Adjacent to the "back" of Area 4, there is a separate, barred-off Quaggoth Pen (see "The Ritual of Selection & Feedin' Time" below).

III. Key Non-Player Characters (NPCs)

The following characters populate The Chained Depths, offering threats, opportunities, or vital information.

IV. Pacing & The Prisoner's Life (GM's Toolkit)

The first part of the session focuses on establishing the oppressive atmosphere and the daily grind. The goal is not to keep the PCs imprisoned indefinitely, but to immerse them in the reality of their situation before presenting concrete escape opportunities.

A. Starting the Adventure: The Initial Shock (Area 4)

Opening Hook (Read aloud to players): "Consciousness returned in a dizzying haze of pain and disorientation. The air hung thick with the stench of unwashed bodies, fear, and something sickeningly metallic. Rough stone pressed against their backs, and the clatter of chains announced their predicament before eyes could fully adjust. They lay in a cramped, dark cell within Area 4, the sickly, pulsing glow of bioluminescent fungi barely illuminating the grimy, moss-covered walls. Around them, whimpers rose, a low growl rumbled from somewhere nearby, and the sharp crack of a whip echoed in the damp confines."

Initial Situation (Area 4: The Slave Pens):

• Location: PCs are in a communal holding cell within Area 4.
• Conditions: PCs start with no gear (or only very basic, hidden items if a rogue/monk has a trick). They are likely manacled (DC 10 Strength check to break non-magical manacles, harder if magical). They are weak from travel/capture.
• Visuals: Grim, moss-covered walls. Iron bars, heavy doors. Stench of unwashed bodies, fear, and waste.
• Sounds: Whimpers, distant growls from the Quaggoth pen, whip cracks, scraping chains, Drow speaking in Undercommon. The faint clink-clank of picks echoes from the mining tunnels.

B. The Daily Grind: Forced Labor in the Mines (Areas 1, 2, 3)

After their initial incarceration, the PCs are quickly integrated into the slave labor force and marched into one of the adjacent mine sections (Areas 1, 2, or 3). They are given crude, heavy picks and assigned a section of rock face.

Objective: Survive the brutal conditions, gather information, and cope with the inherent dangers of forced mining.

Conditions: PCs are without gear, likely manacled (possibly with longer chains allowing for mining movement). They are weak, tired, and constantly supervised by Drow Overseers. The air is thick with dust and dampness. The work is endless; hours blur, marked only by shifting guards and gnawing hunger. Their hands bleed, pickaxes feel dull, and quotas are unforgiving.

Activity: Encourage roleplay during the labor. How do they cope? Do they try to observe? Do they try to communicate?

Distributed Narrative Elements (Read aloud as appropriate):

• The Weight of the Mine: "The rhythmic clink-clank of picks reverberated from the deep tunnels. A legion of the damned toiled, their only purpose to feed the gaping maw of Narathzul and its Spider Queen. The air here was even thicker, heavy with the scent of damp earth and the biting metallic tang of the silver they were forced to claw from the rock. Every breath was a rasping effort, sometimes dissolving into a dry, tearing cough. The chill of the rock seeps into your bones, and the pervasive dampness never leaves. Every swing of the pickaxe feels like a gamble against the rock itself. Each swing is a desperate prayer for the next breath, the next moment of false rest, and the hope that the rock doesn't decide to take your life. You chip away at veins of raw ore, silver glinting dully in the weak fungal light. Every ounce you extract is another drop of sweat, another gasp for air, destined only to fuel the Drow's insatiable hunger for power and wealth. There is no dignity, no reward, only the lash if the quota isn't met."
• The Physical & Mental Toll: "Shoulders burned, a dull ache that had become as constant as the dust in their lungs. Spines twisted into perpetual knots from the cramped tunnels. Hands, calloused and cracked, bled anew with each strike, the worn leather bindings offering little protection. Wounds festered in the damp, unyielding chill; here, there was no comfort, only the crude salve of indifference. Hours bled into other hours. No sun marked the passage of time, only the dwindling oil in the few lamps, and the increasing ache in their bones. Sometimes, minds would drift – to sunlight, to open fields, to the crisp scent of a sea unseen in years – before the grim reality snapped them back."

Key Checks (Integrated into Daily Life & Consequences):

Pacing Note: A single failed skill check should escalate the situation or complicate the objective, but not immediately lead to overwhelming force, TPK, or character death. Consequences should be tiered.

• Athletics/Constitution Saving Throws (DC 10-12) to endure labor:
  • Success: You manage to keep up, avoiding exhaustion or attracting attention.
  • Failure: You falter, drawing the eye of an Overseer. You gain 1 level of exhaustion, or endure a non-lethal whip lash (1-2 slashing damage, but no lasting injury), pushing you to work harder. You are not immediately dragged away or singled out for public punishment unless you continue to defy.
• Perception (DC 12) to notice details:
  • Success: You clearly observe a guard's routine, a weakness in the mine, or a key behavior of an NPC.
  • Failure: You fail to notice the specific detail. You might catch a fleeting glimpse, but it's not clear enough. The opportunity for that specific observation is lost, but no immediate alarm is raised.
• Investigation (DC 10) to find hidden things:
  • Success: You discover a loose stone, a dropped tool, or a weak point.
  • Failure: You find nothing immediately useful. You remain unnoticed, but your search yields no immediate results for that attempt.
• Stealth (DC 10) to observe quietly:
  • Success: You move unnoticed.
  • Failure: You draw a quick, passing glance from a guard. "What was that? Just the wind... no, I heard something!" the Drow might mutter, looking vaguely in your direction for a moment before returning to their duties. No immediate alarm, but you lose the element of surprise for a moment and might need to act quickly to avoid further scrutiny.
• Persuasion/Intimidation (DC 12) with other captives/Varis:
  • Success: You get the information or influence the NPC as intended.
  • Failure: The NPC is too frightened, distrustful, or simply unhelpful. Varis might sneer and demand a higher price, or simply ignore you. No immediate alarm, but the social attempt fails, and you might have to try a different approach or another NPC later.

C. Mining Accidents: The Constant Threat

These are regular, smaller hazards that punctuate the daily grind, reinforcing the dangers and the cheapness of slave life. They should occur periodically during the "Daily Grind" phase (IV.B), separate from the major "Cave-In" escape trigger. These accidents are why the Drow use expendable slaves.

• Trigger: A minor tremor, a sudden collapse of a nearby rock face, a burst pipe, or a sudden rockfall within the mining tunnels.
• Scene: The ground might suddenly shake, dust fills the air, or a section of the tunnel overhead gives way.
• Distributed Narrative: "A sudden rumble, a low growl from the earth itself, sent a jolt of terror through the cavern. Pebbles showered down from the ceiling as wooden supports groaned under immense weight – the ever-present fear of collapse, of swift burial."

Consequences & Opportunities:

• Danger: PCs (and nearby NPCs) might be caught in the immediate danger.
  • Dexterity Saving Throw (DC 12): To avoid falling debris (take 1d6 bludgeoning damage on a failed save).
  • Constitution Saving Throw (DC 10): To avoid inhaling too much dust (gain 1 level of exhaustion on a failed save).
• Casualties: Often, an NPC miner will be injured, trapped, or killed by such an accident. The Drow guards typically show little concern beyond securing the area and ensuring the remaining labor continues. This is a stark reminder of the expendability of life here.
• Opportunity: The chaos of a small accident can create brief opportunities:
  • Distraction: Drow guards momentarily focus on the accident, potentially leaving a path unguarded, or dropping something small and useful (a loose key, a pouch of low-value coins, a crude tool).
  • New Paths/Weaknesses: An accident might reveal a previously hidden crevice, a loose section of a supporting beam, or a structural weakness the PCs can later exploit.
  • Improvised Tools: Fallen debris might contain sharp shards of rock, splintered wood, or broken mining tools that can be repurposed as crude weapons or tools.
  • NPC Reactions: Observe how other prisoners react. Bewar might try to organize help, Skitter might see an opportunity for illicit scavenging, Gwali might immediately snitch on anyone trying to exploit the chaos.

D. The Ritual of "Selection" and "Feedin' Time" (Area 4 & Quaggoth Pen)

This event is a recurring, brutal ritual, whose purpose is to reinforce the Drow's cruelty, create constant tension, and offer a chaotic opportunity for observation or a subtle interaction amidst the horror. This event will occur periodically throughout the PCs' captivity, perhaps once every Drow 'shift' cycle (roughly every 8-12 hours of in-game time), or as a consequence of major defiance. As the GM, you decide the exact timing to best serve pacing and tension.

The Drow's Cruelty (Read aloud as appropriate): "The low growls from the Quaggoth pen (adjacent to Area 4) carried the promise of 'Feedin' Time' – a Drow spectacle where suffering was entertainment, a stark reminder that life here was cheap and fleeting. A whip cracked in the distance, a sound that made every prisoner flinch. It was a constant reminder of the Drow overseers' omnipresent threat; hulking brutes with eyes like chips of flint, caring nothing for exhaustion, only for the ore quota, a quota which seems to increase daily, regardless of the dangers of the mine. The Drow guards moved with cruel efficiency, their dark eyes missing nothing, always searching for weakness or defiance to crush."

"Feedin' Time" Encounter (Survival Challenge):

Quaggoth CR 2 Medium humanoid (Quaggoth), chaotic neutral

Armor Class 13 (natural armor) Hit Points 45 (6d8 + 18) Speed 30 ft., climb 30 ft. STR 17 (+3) DEX 12 (+1) CON 16 (+3) INT 6 (-2) WIS 12 (+1) CHA 7 (-2)

Skills Athletics +5 Damage Immunities poison Condition Immunities poisoned Senses darkvision 120 ft., passive Perception 10 Languages Undercommon Challenge 2 (450 XP)

Wounded Fury. While it has 10 hit points or fewer, the quaggoth has advantage on attack rolls. In addition, it deals an extra 7 (2d6) damage to any target it hits with a melee attack.

Actions Multiattack. The quaggoth makes two claw attacks. Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.

When "Feedin' Time" is triggered, the PCs and a handful of other prisoners will be herded towards the heavy barred opening leading to the Quaggoth Pen (adjacent to Area 4).

• Setup: Guard Mal'sar Xildos (and possibly another generic Drow Overseer) will be present, relishing the spectacle. 1-2 Quaggoths (CR 2 each) will be in the pen.
• Objective: Survive the Quaggoths' rampage without becoming their meal.
• Scene: "Mal'sar's sneering face fills the torchlight as the heavy bars groan open, revealing the stinking, blood-slicked floor of the Quaggoth Pen. A guttural snarl erupts as two shaggy, clawed beasts surge forward, eyes glinting with predatory hunger. Mal'sar gestures with his whip, and a few terrified, whimpering prisoners are shoved through the opening. 'Feedin Time!' he cackles, as the guards place bets on who will be dinner
• Mechanics:
  • Initiative: Roll initiative for PCs, Quaggoths, and any designated "prey" NPCs.
  • Quaggoth Behavior: The Quaggoths are driven by hunger and Mal'sar's sadistic prodding. Their primary targets will be the most vulnerable or easiest to catch prisoners. They are looking to grab and devour, not engage in prolonged combat with well-defended targets.
  • Survival: PCs must use their wits, agility, and any scavenged items (or quick thinking with the environment) to avoid the Quaggoths. This is not a fight to the death against the Quaggoths for the PCs, but a desperate evasion.
  • Evasion/Stealth (DC 13): PCs can attempt to hide among the other prisoners, squeeze into small crevices within the pen (if any), or use the chaotic movements of others as cover. Success means the Quaggoths ignore them for that round, focusing on a different victim.
  • Athletics/Acrobatics (DC 12): PCs can attempt to climb the bars (if allowed by GM), scramble over piles of bones, or dodge incoming attacks. Success means they avoid being grappled or hit.
  • Consequences of Failure: If a PC is caught by a Quaggoth, they are grappled. If they cannot escape the grapple on their next turn, the Quaggoth will attempt to drag them away from the group or down to the ground. If a Quaggoth successfully grapples and holds a target, it will attempt to deal damage (Bite attack) and then, if the target is incapacitated or killed, it will immediately begin to devour them.
  • The Aftermath: Once a Quaggoth catches and incapacitates/kills a prisoner (or two, depending on how many Quaggoths are present and how long the GM wants the scene to last), Mal'sar will eventually crack his whip and command the beasts back into their inner cage. The heavy bars will clang shut, leaving behind the gruesome evidence of the "feeding."
• Opportunities within the Chaos:
  • Scavenging: Amidst the panic and the Quaggoths' focus, a PC might notice a dropped Drow item (a minor coin, a discarded ration, a broken weapon shard) or something valuable near the pen's edge. Investigation (DC 14) during the chaos.
  • Observation: The PCs might observe a specific routine of Mal'sar, a subtle weakness in the bars, or a hidden latch he uses. Perception (DC 15).
  • NPC Interaction: PCs might witness Gwali snitching on another prisoner, or Brag trying to salvage dropped food.

E. The End of the Day: Return to the Cell

After the day's grueling labor and any intervening events (including "Feedin' Time" if triggered), the Drow will herd the remaining prisoners back to their cells in Area 4.

Scene: "The distant hum of mining machinery slowly fades as the Drow overseers bark their final commands. Bruised, battered, and utterly exhausted, you are shoved back into the familiar stench and oppressive darkness of your cell. The heavy clang of the cell door locking shut echoes the finality of the day's torment. The faint glow of the phosphorescent moss is your only comfort, casting long, wavering shadows across the grim faces of your fellow captives."

Conclusion:

The adventure for this specific day ends here. Players have survived the daily grind, endured the threat of the mines, and faced the terror of "Feedin' Time." Any items they managed to scavenge, information they gathered, or observations they made throughout the day are now theirs to keep, ready for future planning and the ongoing struggle for freedom in the days to come.

GM Note: This conclusion sets the stage for the next day, or for a period of downtime where players can consolidate resources, plan, and interact further with the NPC prisoners before another day's torment or a potential escape attempt.
