The Frozen Witch's Bargain
The Frozen Witch's Bargain
The party is lured to a remote, snowbound monastery by rumors of an ancient artifact, only to discover that the monks have unknowingly made a pact with an eldritch entity imprisoned in the frozen depths. As the creature begins to break its chains, the adventurers must decide whether to destroy the monastery, negotiate with its abyssal master, or find a way to re-bind it before the Frost lands are consumed by eternal winter.
Read Aloud
The howling wind cuts through your furs like icy daggers as you trudge through knee-deep snow toward the silhouette of Whitestone Monastery on the horizon. Black stone walls jut from the white wasteland like broken teeth, and even from a distance, you notice something unnatural about the structure—no smoke rises from its chimneys despite the killing cold. The path beneath your boots is paved with ancient stone, yet patches of frost bloom across it in patterns that seem almost deliberately arranged, as if some invisible hand has been rearranging them. A wooden sign, half-buried, marks the monastery's name in faded runes. Behind you, the blizzard has erased your tracks entirely. Ahead, the monastery's gates hang open, and through the falling snow, you hear a faint sound—not wind, but something that might be singing, or screaming, or both.
Description
The party approaches the remote monastery after a harrowing journey through the Frost lands. They were hired by a merchant who claims an ancient Rune of Binding was hidden here centuries ago—it could be sold for a fortune to the right collector. The monastery sits isolated on a high plateau, surrounded by sheer drops and accessible only by the narrow path the party now walks. The environment is deeply unsettling: the frost patterns are too regular, the silence too complete, the air carries an electric, wrong smell—like metal left too long in winter. The gates are ornate but weathered, carved with imagery of monks in supplication before something vast and geometric.
DM Notes
Establish atmosphere early. Allow the party to make DC 12 Intelligence (Arcana) or DC 13 Wisdom (Insight) checks to sense something is magically wrong here. The frost patterns are not natural—they mark the perimeter of a containment circle, though this won't be obvious yet. If a party member touches the rime on the gates, they feel a subtle pulse, like a heartbeat. The distant sound is the entity's dreamlike vocalizations, audible only to those within a few miles. Play up the isolation: once inside the gates, the storm becomes harder to navigate back through. This is a pressure point—leaving later may be difficult.
The Monastery's Frozen Interior
Read Aloud
You pass through the gates into a cloistered courtyard where snow has drifted into dunes against the inner walls. Here, time seems to have stopped mid-catastrophe. A massive bronze bell hangs from an ornate frame, its surface etched with frostbite, and beneath it lies the frozen corpse of a monk, robes clutching his chest as if he died mid-prayer. The monastery's main building looms four stories high, its windows dark and empty. But as you enter through the heavy wooden doors—which creak open as if expecting you—warmth spills out, a terrible, wrong warmth. Inside, the monastery's warmth creates a gradient: the entrance hall is pleasantly temperate, but deeper within, you see your breath misting in patterns that shift against the air currents. Candles flicker along a corridor to the east, some blue, some white. A spiral staircase descends into darkness at the western end of the hall, and you hear a rhythmic dripping sound echoing from below. A notice board near the entrance bears a single, recent entry: "The Gift speaks to us in dreams. Brother Aldric has begun transcription of its words. Do not disturb the lower sanctum. — Abbot Mortis."
Description
The party enters the monastery proper and discovers a structure wracked by inexplicable contradictions. The entrance hall is lined with religious iconography—but the images have been defaced, their eyes gouged out. The corpse of Brother Gavin lies frozen outside; inside, the air itself grows oppressively thick. The party can explore three main areas: the dormitory (second floor), the library and scriptorium (first floor, east wing), and the lower sanctum (below ground, west wing). At this stage, no immediate threats are present, but environmental clues hint at something deeply wrong. The monks are not visible, though some chambers show signs of habitation—beds still warm, meals half-eaten, scattered pages covered in increasingly illegible handwriting.
DM Notes
This is the investigation phase. Let the party explore freely but establish time pressure: every 15 minutes spent exploring, they hear a deep groan echoing from below, and the temperature drops by 5 degrees. After 1 hour, the lower sanctum doors will begin to bulge outward. Clues to find: (1) In the scriptorium, pages showing Brother Aldric's handwriting degrading into incomprehensible symbols; (2) In the abbot's chambers, a ledger documenting the monastery's decline and the arrival of "the Gift" three months ago; (3) The dormitory shows monks sleeping in unsettling positions, their mouths open, lips blue. They are alive but will not wake. A DC 14 Medicine check reveals they are in some kind of prolonged magical slumber. (4) A locked reliquary in the library contains a leather-bound journal with the true story of the Rune of Binding and how it was placed to contain something far older than the monastery itself.
The Lower Sanctum Breaches
Read Aloud
A sound like ice cracking echoes through the monastery, and the floor trembles beneath your feet. If you have not yet ventured below, the doors to the western staircase buckle inward with terrible force, and blue-white light floods the entrance hall, casting impossibly long shadows. If you are in the lower sanctum already, the walls themselves seem to weep—not water, but a thick, viscous substance that glows faintly and smells of deep ocean and decay. The air grows suffocatingly cold. You hear a voice, not words exactly, but meaning conveyed directly into your minds: hunger, ancient and infinite, and a single coherent thought—"SHOW ME THE SUN." The remaining monks, wherever you have encountered them, begin to stir, their eyes rolling open to reveal pupils dilated so wide their eyes appear entirely black. They speak in unison, their voices layered like many throats speaking from one body: "It is awake. It remembers. It hungers." One by one, they begin to move toward the staircase descending deeper, as if compelled by invisible chains.
Description
The entity imprisoned beneath the monastery—a Void entity known only as "The Devourer" or "She-That-Sleeps-Below" in fragmentary historical records—is breaking free. The containment rune has been weakened by the monks' unwitting bargain. They mistook the creature's psychic emissions for divine visions, fed it their faith and prayers, and inadvertently provided it with anchors to reality. The lower sanctum is a vast, circular chamber carved from living rock, its floor an intricate mandala made of crystallized salt and bone. At its center, the Rune of Binding glows with fading light—but its center has cracked. From the crack, a dark, oily substance seeps, and the temperature drops to lethal levels. The remaining monks are enthralled; the party must decide whether to save them, stop them, or ignore them.
DM Notes
This is the turning point. The entity itself will not emerge for another round or two, but its influence is now undeniable. Offer the party choices: (1) They can attempt to reinforce the Rune of Binding using magic (a DC 16 Arcana check, requiring a spell slot of 4th level or higher and an Intelligence save to resist the entity's psychic backlash). (2) They can try to save the enthralled monks (DC 14 Wisdom save for each monk to break free of compulsion, or a Greater Restoration spell). (3) They can confront something terrible—the entity's avatar or an aspect begins to manifest. The enthralled monks block the staircase; combat may be unavoidable. Use this to transition to the next encounter while maintaining narrative tension.

The Thralls of the Lower Sanctum
mediumMonsters
Tactics
The five monks and Brother Aldric act as a unified force, moving with eerie synchronization. They do not speak or scream, only vocalize in unison when using abilities. Their objective is to protect the staircase to prevent the party from reaching the Rune of Binding deeper below. They use grapple tactics to restrain party members, attempting to drag them toward the cracks in the sanctum floor where the entity's presence is strongest. Aldric acts as a secondary leader and can cast Command (DC 13 Wisdom save) once per encounter, forcing a creature to use its reaction to move toward the center of the chamber. Once three monks are defeated, the rest attempt to flee deeper into the sanctum. They do not pursue beyond the sanctum itself.
Terrain
The Lower Sanctum is a circular chamber 60 feet across with 20-foot ceilings. The floor is carved into an intricate mandala pattern that glows faintly with contained magic. At the chamber's center is a 15-foot diameter circle of crystalline salt where the Rune of Binding sits—cracked, pulsing with sickly light. The air is brutally cold (a creature that starts its turn in the chamber must succeed on a DC 12 Constitution save or gain one level of exhaustion; this resets each day). Visibility is reduced to 50 feet due to thick, supernatural mist that rises from the cracks. The floor is slick with ice—any creature that moves more than 30 feet in a single turn must succeed on a DC 12 Dexterity save or fall prone. There are six pillars spaced evenly around the chamber; they provide half cover.
The Entity's Manifestation
hardMonsters
Tactics
The Devourer does not fully manifest—the Rune still constrains it enough that only an avatar emerges: a writhing, semi-corporeal form of shadow and teeth, perhaps 12 feet tall at its tallest point. It cannot leave the confines of the mandala circle at the sanctum's center. It attacks with psychic force and jagged appendages, targeting whoever damaged the Rune most recently or whoever shows the greatest magical potential. Each round, it attempts to psychologically dominate one creature (DC 14 Wisdom save or be frightened until the end of their next turn). When reduced below 30 HP, it begins to dissipate, shrieking directly into the party's minds (DC 14 Wisdom save for all creatures in the chamber or take 5 (1d10) psychic damage). It does not flee or parley, but focuses on maximizing damage to prevent further interruption of its awakening. If reduced to 0 HP, it collapses into shadow and dissipates, but a new pulse emanates from the cracks in the Rune—it is buying time, not being defeated.
Terrain
Same as previous encounter: the circular sanctum with the central mandala. The mist grows thicker (visibility 30 feet) as the entity manifests. The cold intensifies (Constitution saves become DC 13). The pillars now crackle with frostbite and provide three-quarters cover. The cracks in the Rune grow larger each round: at the start of round 2, anyone in the inner circle (within 10 feet of the Rune) must make a DC 12 Dexterity save or take 3 (1d6) cold damage. This increases to 5 (1d10) at round 3, and 7 (2d6) at round 4. The Rune will fully shatter at round 5, releasing the entity completely.
The Rune's Fate and the Monastery's Choice
Read Aloud
The avatar shatters like glass, its essence dissipating into smoke and starlight—or perhaps into deeper darkness, you cannot tell. For a moment, the world holds its breath. The mist clears. The cracked Rune lies at your feet, its glow fading to embers. Abbot Mortis stands in the chamber's entrance, leaning heavily against the frame, his face streaked with tears. "You have bought us time," he says, his voice barely audible. "But time is all it is. The Rune will fail completely within hours. The creature will wake fully. Unless..." He pauses, seeming to struggle with the weight of what he must ask. "Unless you will help me attempt the Ritual of Recasting. It has not been performed in three hundred years. It will require a blood sacrifice—a willing one. And the monastery will not survive the forces involved. All of this, burned to nothing, to keep the thing below asleep."
Description
The party has destroyed the avatar but not solved the fundamental problem: the entity remains imprisoned but imprisoning, and its cage is failing. Abbot Mortis presents them with a terrible choice. The Ritual of Recasting can restore the Rune, but only if: (1) A willing sacrifice gives their life to anchor the new binding, and (2) the monastery is destroyed in the ritual's execution—the sanctum will collapse, taking everyone inside with it if they do not flee immediately after the sacrifice is made. Alternatively, the party can attempt to simply flee with the Rune itself, but Mortis insists this will doom not just the monastery but potentially the entire region once the creature's full power is unleashed. A third path exists but is not immediately apparent: if the party casts Greater Restoration on at least three monks and brings them to consciousness, one of them—Brother Caius, a former scholar—can suggest a binding ritual that uses the party's combined magic instead of a blood sacrifice, though it will permanently mark each caster with a curse of cold sensitivity and will drain one level from each.
DM Notes
This is the moral heart of the session. Present the choices clearly but do not push the party toward any one outcome. If they choose the blood sacrifice path, any party member or NPC can volunteer. If a monk volunteers, reinforce the tragedy—these are real people with names and personalities, not abstract tokens. If the party chooses to flee, Mortis will not stop them, but he will remain behind. If they choose the greater restoration path, celebrate their cleverness but emphasize the cost: permanent magical scarring. This scene should feel weighty and consequence-laden. The monastery's destruction should be described vividly—a final, apocalyptic image of stone and snow and light. After the choice is made, allow 30 minutes of real time for the party to decide and execute their chosen path, then transition to the conclusion.
Treasure & Rewards
A crystalline disc, 6 inches across, inscribed with geometric patterns. Though cracked, it resonates with cold power. When placed upon a wound or curse, it will suppress magical effects for 1 hour. The rune cannot be repaired or moved without a DC 16 Arcana check; improper handling risks releasing its contained force as a 4d6 cold damage explosion in a 10-foot radius.
A detailed record of the monastery's history and the entity's arrival. Contains coded references to other sites of containment across the world—places where similar 'gifts' have been imprisoned. Worth 50 GP to a scholar; could serve as a hook for future adventures.
Three bottles, recovered from the monastery's stores. Each grants resistance to cold damage for 8 hours.
Brother Aldric's journal, containing fragments of the creature's psychic emissions. Most are incomprehensible, but certain phrases repeat: 'The sun remembers me,' 'The ice is not my prison but my cradle,' 'Wake the sisters beneath the other peaks.' This is not treasure but information—a seed for future adventures.
Story Hooks
The discovery of multiple containment sites in Mortis's ledger suggests a vast conspiracy—or perhaps a warning system left by an ancient civilization that knew of the void entities. If the party saved monks or made allies of NPCs, those survivors will carry the knowledge of what transpired and may seek out the party later for help with other sites, or to prevent the entity's brethren from awakening. If a party member was marked with the curse of cold sensitivity, they will attract the attention of forces that feed on such things—winter hags, frost druids, and worse. The Rune's fragment, though bound, still whispers. A character holding it might experience visions of the creature's dreams or memories, hinting at older, deeper horrors beneath the world.
Conclusion
Wrap Up
The monastery stands no more. Whether consumed by ritual fire, collapsed into the depths, or simply abandoned to the elements, Whitestone Monastery is erased from the world—a scar, nothing more. The surviving monks (if any) disperse to other sanctuaries, carrying word of what they witnessed. Abbot Mortis, if he survived, will send word through clerical networks to other orders, warning them to scrutinize their own faith for signs of eldritch contamination. The merchant who hired the party will be disappointed about the Rune's damaged state, but a smaller payment will be offered—enough to make the journey worthwhile, though not the fortune promised. The true reward is survival and the knowledge that something infinitely hungry was pushed back, if not permanently defeated.
Cliffhanger
On the third night after leaving the Frost lands, one party member dreams of the entity. In the dream, it does not rage or threaten. Instead, it speaks with an almost paternal tone: "You did well, small ones, to preserve my sleep a moment longer. But the ice melts, always melts. When it does, I will remember you. And when my sisters wake..." The dream shatters, and the dreamer wakes gasping, to find a pattern of crystalline frost covering their window in geometric shapes—the same pattern that marked the monastery's containment circle. The frost is warm to the touch, and it smells of deep ocean and decay.
Next Session Hooks
- The Ledger's Secrets: Mortis's journal references three other sites of containment across the world. One, marked with an urgent notation, lies beneath a fortress in the Spine of the World where an ancient order once guarded a 'Sleeping Sister.' Letters found in the monastery suggest contact was lost with that site six months ago.
- The Marked Curse: If a party member accepted the curse of cold sensitivity, they will begin to experience whispers in cold places and are slowly becoming attuned to the void. Strange figures watch them from winter shadows. They must seek a way to break the curse before it transforms them into something else entirely.
- Survivors' Testimony: Any monks or NPCs who survived will reach out to the party, either seeking help or warning them of strange phenomena beginning to occur in other monasteries, temples, and holy sites across the realm. Madness is spreading among the faithful.
