Adventures

The nursery is where the Deep is kindest. And kindness is only ever the first thing a wound wears.
— Sporefather Umble, of Softloam

An adventure in the deep is not a dungeon with the lights turned off. It is a walk through a living, watching thing that would rather feed you than fight you—until it wouldn't. The best sessions in the Weave Below let the players fall a little in love with the place first: the rose-lit meadows, the milk sweeter than any surface cream, the enormous patient breathing of the world. Only then does the reach turn, and the love becomes the leverage. Give the horror a face they will grieve, and the wonder a cost they will feel, and the Deep will run itself.

What follows is one complete adventure, ready to run for a party finding its feet in the Velvetfields, and a spread of seeds for every reach and every tier that comes after. Read the boxed text aloud; keep the awe generous; and never forget that the greatest power the players can reach for—symbiosis—is also the thing most eager to reach back.

The Nursery Turns

A complete starter adventure for four to six characters of 3rd to 5th level, set in the Velvetfields around Softloam and the Nodding Pastures. The party is asked to backtrail a sickening herd, find what was walked down from the surface, and cut it out before the gentlest reach of the Deep turns rotten from the inside.

Background for the Dungeon Master

Three blooms ago, a surface delver came down through the Downstair Gate with something caught in the welt of one boot: a blight-seed, a dormant spore-pod of the Blight Below, no larger than a plum stone and patient as winter. The Sporesung wardens read the delver for infestation, found nothing, and waved him through—the seed was asleep, and a sleeping thing has no loud mind to catch. He walked to Softloam, sold his cattle-hides, and left. The seed did not.

It rooted in the low, damp ground at the western edge of the Nodding Pastures, in an old Underdark seam where the meadow runs thin, and it has been drinking there ever since—slowly, so as not to be noticed, exactly as the Blight always begins. It has grown into a weeping bloom the size of a wagon, and it has begun to sing: a soft, false communion, a nursery-lullaby version of the Pale Chorus, pitched to sound like the Weave itself. The spore-cattle that graze that seam have caught it first. Their milk has curdled; their eyes weep black; and one young shepherd who slept too many nights on the western pasture has caught it too.

The seed is not yet a warfront. It is a cell—a single cantor of the Blight tending a single seed, with a handful of the taken around it. But the next Chorusbloom (see Chapter 2's spore conditions) is only days away, and when the meadows bloom heavy the seed will bloom with them and cast its song across the whole reach at once. Sporefather Umble has felt the wrongness the way you feel a wrong note behind a wall. He cannot walk that far anymore, and Warden-Mother Sedge and her Deeproot wardens are a five-day march away at the Weeping Front. So he sends the party. The clock is the Chorusbloom. If the cell is not cut out before it, the nursery turns.

Adventure Hooks

Umble's Summons. The party is already in Softloam—resting, trading, or recovering from the Weeping—when an ash-grey myconid elder lays a soft hand on the nearest one's brow and, without a word aloud, shows them a meadow weeping black. Sporefather Umble pours his spore-tea, names the trouble in gentle riddles, and asks a plain favor of hard people.

Marda Fenn's Plea. The canon Gleaner forager of Softloam (see Chapter 2) begs the party directly: her kin, a girl named Sela who apprenticed to the shepherd-circle, has gone silent inside her own skin. Marda found the weeping seam a week ago and staked it for the wardens, who never came. She is not too proud to pay in milk-shares and everything she has.

The Debt of the Gate. Grimmer, and good for a party with something to answer for: the delver who carried the seed down was the party's guide, employer, or quarry, and the Sporesung wardens at the Downstair Gate have quietly noticed that the rot began the season they arrived. No one accuses them. But clearing the seam is how a descender proves the Deep was right to let them in.

Scene 1: The Weeping Herd

The glow of Softloam comes up gold and warm, and for a breath the Velvetfields are everything the stories promised—dome-huts grown from living puffball, herds drifting like slow clouds, a bell-fungus tolling somewhere out in the rose. Then you see the near paddock. A spore-cow the size of a wagon stands very still while a shepherd draws its milk, and the milk runs into the pail the wrong color: a thin, curdled grey shot through with black. The beast is weeping. Two dark lines run down from its wide gentle eyes and drip from its jaw, and it does not low, and it does not blink. Behind it, on an upturned pail, a girl of perhaps sixteen sits with her hands open in her lap and her face turned toward the light, and she is smiling, and she has not spoken in three days.

This scene is investigation and heartbreak, not combat. The silent girl is Sela Fenn, and she is early on the Infestation track (see Chapter 5)—the false chorus has reached her, but she is still, mostly, herself. Reward players who slow down and look.

Skill Challenge: Read the Rot. Set a soft clock: the party needs three successes before two failures to learn where to walk. Suggested checks, DC 14 unless noted:

a Wisdom (Medicine) or Intelligence (Nature) check confirms the herd's sickness runs downhill from the western seam, not up from the water; a Wisdom (Insight) check on Sela finds a person still home behind the smile, listening to something no one else can hear; a Wisdom (Survival) check backtrails the weeping cattle to the thin western pasture where they last grazed clean; and a Charisma (Persuasion) check earns Sporefather Umble's full confidence, and with it his tea, a warden's fire-lichen stake, and the true name of the deadline: the coming Chorusbloom. On two failures, the party still learns the direction—but Umble cannot spare an escort, and a second cow has begun to weep by the time they leave.

Umble folds your hand in both of his, and the meadow goes quiet inside your skull. “A seed was walked down out of the light,” he says, without moving his mouth. “It sleeps no longer. It has learned to sing like us—badly, the way a child sings a prayer it does not understand—and the young and the gentle answer first. Follow the weeping to its spring. Do not eat there. Do not weep there. And when you find the thing that is singing, do not listen to it. Cut it, root and voice, before the meadows bloom. After the bloom I cannot promise you a nursery to come home to.”

Clues & Complications

d8	On the trail west, the party finds…
1	A fire-lichen warden's stake, snapped off at the root—Marda's mark, pulled up by something with hands
2	A spore-cow standing in the meadow, already dead, already softening, already being taken back down
3	Sela's shepherd-crook, dropped in the grass a mile from where she now sits, its head budding pale
4	A boot-print in the damp, older than the rot, walking up toward the Downstair Gate and gone
5	A drift of black spores that briefly forms a smiling face—and then the party's own faces
6	A stand of hearthcap gone to false-hearth overnight, weeping clear ichor, the blight running ahead of them
7	A young Sporesung of the shepherd-circle, sent to help, who is one wrong step from silent himself
8	Birdsong—except there are no birds in the Deep, and the sound is coming from the seam ahead

Scene 2: The Backtrail

The western pastures thin as the party follows the weeping downhill. The glow curdles from rose toward a sickly yellow, the sweet air turns wet and over-ripe, and the false chorus begins—a lullaby just under hearing, in a voice that is almost the Weave's.

Skill Challenge: Walk Soft. The Deep here notices loud minds and harsh light (see Chapter 2). A party that douses bright lanterns, ropes together, and moves quietly earns Advantage on the coming fight and surprise; a party that blazes light and argues loudly loses surprise and draws the ambush early. Call for Wisdom (Perception) or a group Dexterity (Stealth) check, DC 13, to read the meadow before it reads them.

Combat: The Turned Herd. Where the weeping runs thickest, the seam's first converts are waiting. Run one blight-shroudcat and two chorus-hounds (see Chapter 8)—a corrupted meadow-predator and the pale, patient beasts the Blight grows from the taken. The shroudcat holds motionless as a fold of cloth until a straggler passes, then strikes; the hounds herd the party toward the low ground and the fog beyond. For a party of five 4th-level characters this is a moderate encounter; add a third hound, or a weeping spore-cow that bursts blighted pollen when slain, to press a larger or higher-level group.

The lullaby swells, and the fog in the hollow ahead answers it, and a fold of the pale ground uncurls into a shape with too many joints and no eyes at all. Off to your flanks, two low things that used to be something gentler rise out of the grass without a sound, their hides gone the grey of old candle-wax, their breath coming in a soft wet chorus that is almost, almost singing. The shroudcat does not roar. Nothing here roars. It simply comes.

After the fight, the trail is unmistakable: a broad weeping seam of blight, an old Underdark crack in the meadow's western edge, breathing pale fog into a sunken glade. The birdsong from the clue table, if the party heard it, is loudest here—and it is coming from a bloom the size of a wagon.

Scene 3: The Weeping Seam

The meadow ends at a wound. Where the rose-grass should run on, the ground drops into a sunken glade, and the glade weeps—mottled purple-black, soft as candle-wax, threaded with clear ichor that catches the sick light and drips, and drips. Low necrotic fog pools in the bottom of it, sweet and cold. Pale shapes stand in the fog, upright and swaying, and it takes you a long moment to understand that they were people. A shepherd. A delver in surface leathers. A Gleaner still clutching a foraging-satchel. They turn toward you together, unhurried, and open their mouths, and the lullaby pours out of all of them at once in a soft and patient we.

Hazard: Blight-Fog. The lower glade is thick with Rustfall (see Chapter 2). A creature that starts its turn in the fog, or that takes a Blight attack here, must make a Communion saving throw (see Chapter 5)—this is blight exposure, and a failure means +1 Infestation. Bonded characters feel the pull of the false chorus keenly; the fog is trying to teach them the song. Clearing the seed (Scene 4) lifts the fog within minutes.

Combat: The Taken. The glade holds three blightthralls and two sporewights (see Chapter 8)—the husks of the delver, the lost Gleaner, and a shepherd, plus two of Softloam's own continued dead, lowered back onto their feet by the seam's false song. This is the adventure's hardest ordinary fight; run it as a second combat, with the fog's Communion saves as the true pressure. Do not put Sela here. Reward players who realize the thralls were people: a thrall dropped to 0 with nonlethal intent, and pulled from the fog before the fight ends, may be savable later if the seed dies (DM's call, and a fine reason for the party to hurry).

Scene 4: The Seed and the Chorus

At the glade's heart, half-sunk in the weeping ground, grows the blight-seed: a bloated, translucent pod the height of a standing myconid, veined with slow black light, pulsing in time with the lullaby. Rooted beside it, tending it the way a Sporesung tends a herd, is the cell's cantor—and when the party comes within its reach, the Pale Chorus opens its mouth.

The singing stops. In its place, all at once, from the pod and the fog and the fallen and the very ground, comes a single soft voice wearing a thousand throats. “We know you,” it says, and it does. It says your name. It says the name of the one you lost. “You are so tired of being only one. Of being the small hard lonely thing that dies. We can end that. We can end the dying. Set down the walls, beloved, and be kept—not continued, not remembered, but kept, here, in the warm, in the we, forever. It does not even hurt. Ask her.” And in the fog behind the pod, a girl of sixteen you have never met turns her smiling face toward the light.

The Blight Cell. The climax pits the party against the cantor (statblock below), the blight-seed itself, and any thralls or sporewights that survived Scene 3, rising again on the cantor's call. The seed is the true objective: while it lives, the cantor regains hit points each turn and the fog keeps forcing Communion saves. The Blight-Seed is an object, AC 11, 45 hit points, Immunity to Poison and Psychic damage and to the Charmed, Frightened, and Exhaustion conditions; it cannot act, but every round it remains, one downed thrall in the glade rises with 5 hit points. Destroy it and the cantor loses its regeneration, the fog begins to thin, and the false chorus falters into silence.

Blightward Cantor

The pod bursts like a struck fruit, and the voice comes apart—not into screaming, but into a thousand separate breaths, each one suddenly alone, suddenly small, suddenly afraid, and then gone. The fog stoops and thins. Somewhere behind you a girl draws a long shuddering breath as though surfacing from deep water, and begins, quietly, to cry—and it is her own crying, in her own voice, and she remembers your name. Out in the meadow to the east, very faint, a bell-fungus begins to toll the pale hour, and the glow is coming up gold.

Continuing the Story

Cutting one cell does not cure the Bruise, and a wise DM lets the victory cast a shadow. The delver who carried the seed down is still out there, and may not have known—or may have. Warden-Mother Sedge arrives a day late with her Deeproot wardens, burns the glade clean, and marks the party as people worth calling on; her gratitude is a doorway to the Weeping Front and everything past it. Sporefather Umble, who has now spent a great deal of a very old strength, asks the party to carry a warning to the Downstair Gate: the surface is a door the Blight has learned to knock on. And Sela, brought home and continued in the good way, will remember the party for the rest of a long life—which is, in the Deep, a debt that outlives the grave.

Rewards

Beyond a grateful commune's milk-shares, the Gleaners' standing, and Umble's favor, the seam yields two lasting prizes. First, dormant and clean at the glade's cleared heart, a shed Choruscap, the Listening Bloom—a symbiote that grants telepathy and a hard-won calm against fear and charm, and a fitting trophy from a place that tried to sing the party under. Any character may bond it during a rest (see Chapter 5 for bonding, Communion, and the price such gifts carry). Second, Warden-Mother Sedge presses on the party a Sear-Spore Censer—a grown Deeproot tool, an uncommon living item that burns blight-fog to nothing and scalds the taken (see Chapter 7). Between the two, the party leaves the Velvetfields carrying both a new voice in their heads and a new fire in their hands—which is, more or less, the whole bargain of the Deep in miniature.

Adventure Seeds

One nursery is a session; the Deep is a campaign. The springboards below are written concrete enough to run from the table and open enough to bend. Each names a reach, a tier, and a trouble already in motion; roll, or choose the one your party has been walking toward without knowing it. After the table, three campaign frames sketch how the whole arc of the Deep might unfold, from the first descent to the dreaming wound at the world's root.

Adventure Seeds of the Deep

d12	Reach	Tier	Springboard
1	The Velvetfields	1–4	A prize herd calves a two-headed lure-calf that hums the Pale Chorus; Umble asks the party to carry it, alive, to the Downstair Gate before its song learns the commune's names.
2	The Velvetfields	5–10	Softloam's continued dead have begun stepping out of their sign-post fungi at the pale hour, walking the old boundary and weeping. Something beneath the Nodding Pastures is calling them by name.
3	The Gillforest	1–4	A shelf-village's silk-bridge is being re-spun wrong—into a snare—by spiders no longer minding their circle. Cantica's weavers pay in singing silk for whoever climbs down and reads the pattern.
4	The Gillforest	5–10	The Hush Canopy has fallen silent mid-commune; a thousand myconids stand mid-thought, and the one novice still moving swears a loud mind walked in among them wearing a guest's face.
5	The Bruise	5–10	A Deeproot patrol was taken at the Weeping Front; one is freshly cocooned in the Chorus Pits and may be mostly himself. Warden-Mother Sedge cannot order a rescue—only point, and start counting.
6	The Bruise	11–16	The Rustgyre's guarded seed has quickened; the permanent spore-storm widens a drifting each bloom, and the Pale Chorus has begun speaking the party's own memories back at them out of the fog.
7	Lumen Hollow	1–4	A weeping crate at Vane's Landing. Cassira Vane pays well and asks little: learn whether a Blight-tainted good has been walked into the Driftmarket before a customs-priest burns the whole wharf as a precaution.
8	Lumen Hollow	5–10	The Mourning Glass has begun showing the drowned dead of people not yet dead—including, last night, a Gleaner councilor who woke screaming and has not been seen since.
9	The Marrow Roads	5–10	Lord-Continuant Ashveil's gilded invitation: fetch a reliquary from the Skull Vault, name your price. He omits that it anchors his own continuance—and that a rival at the same table wants it broken.
10	The Marrow Roads	11–16	Bone-fungus has reached the Ribways' load-bearing arches; the Bone City of Charnholt will fall into the dark within a bloom unless the rot's singing heart, deep in the titan's marrow, is cut out.
11	The Heartweave	11–16	A beloved pilgrim who walked into the Dreaming Bloom a season past is sending dreams back—dreams now bleeding into the Velvetfields and waking the herds screaming. Bring her out, or let her go, before her dreaming rewrites the reaches above.
12	The Heartweave	17–20	The Deep has begun to dream the surface: a pilgrim's spoken wish took root as a second sun over the Nodding Pastures, and reality spreads outward from the Dreaming Bloom like a stain. Only something offered at the Threshold of Sighs can close the eye.

Campaign Frame: The Nursery and the Front (Tiers 1–2)

Begin the party as new descenders under the wing of the Sporesung, with Softloam as their hearth and Sporefather Umble as the patient hand on their shoulder. Local troubles—a turned herd, a weeping crate, a lost apprentice—teach them the manners of the Deep: light discipline, walking soft, the true cost of the symbiotes they will inevitably bond. But every thread pulls the same direction. Each blight-seed walked down from the surface, each cocoon in a distant pit, each memory the Pale Chorus speaks back at them, draws the party toward the Weeping Front, where Warden-Mother Sedge holds a line that moves the wrong way every season. By 10th level they are no longer descenders but wardens in all but name, and the question is no longer whether the Bruise will reach the nursery, but whether they can make it stop.

Campaign Frame: The Long Politics of the Deep (Tiers 3–4)

Now the Deep opens outward, and the danger wears finer clothes. Lumen Hollow makes the party into names—traders, fixers, people Cassira Vane will vouch for—and the Marrow Roads make them into pawns, courted by the decadent Hollowed Court and its relic-lords who have continued for centuries and mean to continue a while longer. The Blight works differently here: not fog and thralls, but a tainted good in a caravan, a cantor's whisper behind a councilor's smile, a reliquary that is also a leash. This is the campaign of intrigue and delving, of choosing which century-old lord to trust and which relic is worth the curse on it, all while the Rustgyre widens in the south and Suppuratehold's drowned towers glow a little brighter each bloom. The party learns that the Deep can be lost to politeness as easily as to rot.

Campaign Frame: The Dreaming Wound (Tier 4 and Beyond)

At the last, the road runs to the Heartweave, where the Deep stops being a place and becomes a mind, and where reality itself grows negotiable (see Chapter 2). Here the campaign's oldest questions come due. What is the Blight, that it can wear the Weave's own voice? What does continuance cost, and what does it save? And what is a self worth—the very question the Sporesung and the Pale Chorus have been arguing across the whole campaign—now asked of the party directly, by the Dreaming Bloom, which is always, softly, inviting them to set down the walls and stay. Epic play in the Deep is not a bigger battle but a truer choice: to close the dreaming eye, to speak a wish and mean it, to give up a real memory at the Threshold of Sighs and walk into the soft country to end the thing at its root. Some parties bring their friend out of the Bloom. Some let her go properly. A rare few walk in themselves, and return changed, speaking in a plural that is not the Blight's—and that, in the Deep, is the closest thing there is to winning.
