Features

Hollow Star Patron (custom reflavor of The Fiend)

class (reflavored Fiend patron, SRD compatible mechanics) Level 1

Nera's otherworldly patron is the Hollow Star, a distant shadowy entity glimpsed only as a red star. At level 1 she gains the Dark One's Blessing: when she reduces an enemy to 0 hit points or finishes a Short/Long Rest, she gains temporary hit points equal to her Charisma modifier + her warlock level (currently 6).

Shadow Portal (custom)

villain feature (balanced against Misty Step) Level 3
1/day

Once per day, as an action, Nera can step through a veil of shadow and teleport up to 60 feet to a space she can see in dim light or darkness. She uses this to attempt her escape when reduced below half hit points; in the collapsing shrine, the DM may rule the portal fails or deposits her back into danger.

Ritual Devotion (custom)

encounter mechanic Level 3
encounter-specific

While her ritual is uninterrupted, Nera gains 10 temporary hit points (see DM scaling guidance). A successful DC 15 Intelligence (Arcana) check to disrupt the ritual causes her to lose her next action.

Eldritch Invocations (Agonizing Blast, Misty Visions)

class Level 2

Agonizing Blast: add her Charisma modifier (+3) to Eldritch Blast damage on each hit. Misty Visions: she can cast Silent Image at will without expending a spell slot.

Pact of the Tome

class Level 3

Nera's Book of Shadows is a blackened prayer book containing three extra cantrips: Guidance, Sacred Flame, and Toll the Dead. It burns to ash if she dies.

Magic Initiate (Cleric) โ€” Acolyte feat

background feat Level 1
1/Long Rest for Bless

Nera knows the Guidance and Sacred Flame cantrips (Charisma) and can cast Bless once per Long Rest without a slot.

Spellcasting

Charisma DC 14 +6 to hit Level 2: 2 slots

Nera's two 2nd-level slots are her only true slots; she casts Hex, Arms of Hadar, Hold Person, and Suggestion using them. Silent Image is cast at will via Misty Visions.

Behind the character

Character Information

Sister Nera Vex is a tall, gaunt human woman in her late thirties, her ash-gray pallor and white-streaked black hair marking years of devotion spent in smoke-filled shrines and starlit vigils. She moves with unhurried, deliberate grace, as though every step is part of a liturgy only she can hear. Her amber eyes catch light like banked embers, and thin curls of smoke sometimes drift from her sleeves when her patron's attention presses close.

She wears layered ash-gray robes trimmed in faded red, and at her throat hangs a black iron sigil shaped like a closed eye. Nera is calm, mocking, and devout. She speaks in riddles and scripture-fragments, treating violence not as cruelty but as ritual necessity โ€” the pruning of a frontier too stubborn to see the truth she carries. She is not a mindless fanatic; she is a calculating cleric-turned-warlock who weighs every life against the coming of the Ashen Eye, and she will abandon a failed ritual, a failed follower, or a failing body without hesitation.

Beneath the serene mask, however, lives a woman who was once a genuine healer of a small frontier chapel, and the dissonance between that memory and what she has become is the crack through which doubt โ€” and story โ€” can enter. She addresses enemies as 'little flames,' treats her goblin and orc thralls with a shepherd's false tenderness, and reserves her true reverence for the red star she alone seems able to see through the cavern crack above her altar. Her voice is soft, patient, and always two questions ahead of her listener.

Before the adventure

Character Background

Nera Vex was born in Hollowbrook, a logging settlement three days east of Thornwell, the daughter of the town's chapel keeper. She grew up tending the sick, memorizing hymns, and believing absolutely in a benevolent firmament. At nineteen she was the youngest licensed healer the chapel had ever confirmed, and she might have lived and died a beloved village sister if not for the winter of the Gray Fever. The fever took Hollowbrook in a single season.

Nera prayed, fasted, and burned through every remedy in her order's canon, and still the town died around her โ€” including her father, her mentor, and the man she had quietly promised to marry. In her final desperation she turned to a heretical rite from a sealed folio in the chapel's under-crypt: a prayer addressed not to any god but to 'the star that watches between lights.' Something answered. The fever broke in three days.

Hollowbrook called it a miracle, and Nera was celebrated โ€” but she knew what she had heard in the silence after the prayer: a patient, distant voice that did not grant mercy so much as offer an exchange. For years she tried to forget. She transferred to a mission chapel near Thornwell, buried the folio, and served well. Then the dreams began: a red star hanging over a black eye carved in stone, a vault beneath the world, a sigil of iron and ember waiting to come home.

The Hollow Star, patient as geology, resumed its conversation. It taught her that the fever had not been broken but redirected โ€” that Hollowbrook's deaths had fed the star, and that the frontier's suffering could be 'purified' into ascension rather than wasted on plague and banditry. Nera's conversion was not a snapping point but a slow erosion. She left the mission chapel one autumn night, took the folio, and walked into the Skarn Hills.

Over the following year she built the Cult of the Ashen Eye from the wreckage of displaced goblin bands and mercenary orcs, using ritual compulsion, promises of purpose, and the fear of 'the Whisperer' to bind them. She discovered the abandoned Skarn Mine and, beneath it, the sealed Ashen Shrine โ€” an ancient site of the star's forgotten worship. There she found the mechanism that awaits the Ember Sigil, a key lost to the surface world, and began the divinations needed to locate it.

Her letter from the Hollow Star instructs her: recover the sigil, return it to the Vault of the Unseen, and the Ashen Eye will open. She does not fully understand what the Eye is. She suspects she does not need to. Her raids on Thornwell serve three purposes: they supply her with captives for the ritual's blood-tithes, they draw frontier militia away from the hills, and they are, in her theology, the first embers of purification.

She watches her raids personally from ridgelines, cataloguing the town's defenders โ€” including, perhaps, the party itself. She knows she is expendable; the star's letter makes that clear in its cold way. Her ambition is not survival but significance: to be the hand that opened the Eye, the first name spoken in the new dark. Yet the healer of Hollowbrook is not entirely dead. She keeps a chapel hymnal in her pack, sings its songs to her goblins as lullabies, and hesitated once โ€” only once โ€” before burning a farmstead. If spared, interrogated, or offered a genuine alternative to the star's arithmetic, that buried woman may yet complicate everything.

Threads to follow

Unresolved Plots

  • The hooded messenger who delivers the Hollow Star's letters vanishes in black smoke and has never given a name. Nera does not know if it is a person, an avatar, or the star itself, and her attempts to follow it have all failed. Learning its nature could expose the cult's communication network.
  • A second cult agent exists somewhere on the frontier, holding the counterpart cipher. Their identity, location, and purpose are unknown โ€” even to Nera. They could be a merchant, a militia officer, or someone in Thornwell itself.
  • The sealed stone door beneath the Skarn Mine bears a red eye older than any sigil Nera uses. The shrine predates her cult by centuries. Who built it, and why was it sealed rather than destroyed?
  • The Gray Fever that destroyed Hollowbrook broke three days after Nera's prayer. She has never investigated whether other towns were similarly 'answered' โ€” or whether the star engineered the fever itself to make its offer irresistible.
  • Tobin the captive miner heard Nera speak of 'the Vault of the Unseen' and can describe the mechanism behind the altar in detail โ€” knowledge he shouldn't have, unless the shrine showed it to him. Why did the Eye let a miner see?

Beneath the surface

Secrets

  • Nera still carries her old chapel hymnal, hidden in a false bottom of her pack, and sings its songs to her goblin followers as lullabies. If it were found and read aloud, her authority over the superstitious goblins could collapse.
  • She did not break the Gray Fever โ€” she redirected it. She believes the star saved Hollowbrook, but the timing and the voice's exact words suggest the fever was the star's lever, not its gift, and she has never let herself examine the distinction.
  • Her letter from the Hollow Star contains a line she has never told anyone, including Karrash: 'When the Eye opens, the hand that turned the key will not be needed on the other side.' She knows, on some level, that her success means her death โ€” and she is building private escape plans anyway.

What haunts them

Fears

  • Being replaced or discarded by the Hollow Star โ€” dying as an unused tool rather than a chosen instrument
  • That the Gray Fever was not broken but aimed, and that she has spent her life serving the thing that killed her town
  • Facing Mayor Elara Voss and being recognized as the healer who once saved her husband

What drives them

Aspirations

  • To be the first name spoken in the new dark โ€” the hand that opened the Ashen Eye and entered legend
  • To finally understand what the star is and what the Vault of the Unseen truly contains, rather than serving blind
  • To be, somehow, forgiven by the dead of Hollowbrook โ€” a longing she buries under doctrine and would deny with violence if named aloud

Personal quest ยท 1

The Hollowbrook Requiem

Nera wishes to return to the ruins of Hollowbrook and complete the funeral rites she never finished for the fever dead โ€” a rite that requires burning the chapel's hymnal at the altar where she first heard the star. Doing so would sever her last tie to her former life and deepen her pact, but if the hymnal is taken or the rite defiled, the star's hold on her weakens visibly.

Current Stage

Learn where Hollowbrook's ruins lie and what happened during the Gray Fever

Mechanical Rewards
  • Permanent +1 to Charisma (maximum 20) if the rite completes
  • Loses Dark One's Blessing if the rite is defiled; gains Ashen Aegis (resistance to necrotic damage) if it completes
Narrative Rewards
  • Closes the Hollowbrook chapter of her history
  • The Hollow Star speaks her true name, marking her as favored

Personal quest ยท 2

The Second Letter

Nera's orders came sealed in black wax, but the star's messenger โ€” a hooded figure who vanishes in black smoke โ€” delivered only half of a two-part cipher. Nera believes the other half was left with a rival agent, 'the Whisperer's other hand,' somewhere along the frontier. She must find and destroy the counterpart letter before her own role becomes replaceable.

Current Stage

Decode the partial cipher in her letter

Mechanical Rewards
  • Learn the ritual of Shadow Portal refinement, extending her teleport to 120 feet and twice per day
  • Gains the ability to cast Suggestion once per day without a spell slot
Narrative Rewards
  • Learn the identity of a second cult agent embedded in the frontier
  • Secures her position against being discarded

Personal quest ยท 3

The Ember's True Name

Nera knows the Ember Sigil fits the shrine's mechanism, but not what the Eye truly opens. Driven by a hunger she disguises as doctrine, she seeks a hermit astrologer in the Skarn Hills who once charted the red star and may know the Vault of the Unseen's purpose. She wants the truth before she dies for it.

Current Stage

Locate the astrologer's hidden observatory

Mechanical Rewards
  • Learn the Ashen Eye's true nature (GM-defined revelation usable in later acts)
  • Gain one contact: the astrologer, who can identify celestial and planar phenomena
Narrative Rewards
  • Nera's faith is tested by knowledge
  • The party gains a lead on the Vault of the Unseen regardless of outcome

Major Decision

Context

The Hollowbrook rite is interrupted by the party or survivors

Choice Made
Nera may finish the funeral rite and bind herself fully to the Hollow Star, or abandon it and keep the hymnal โ€” her last human tether.
Impact

Completing it: permanent +1 Charisma and necrotic resistance, but she becomes irredeemable and gains the ability to sense the party's location once per day. Abandoning it: she loses Dark One's Blessing permanently but gains the ability to cast Cure Wounds via her Tome, opening a redemption path and changing her combat role toward support.

Major Decision

Context

Nera learns the rival agent holds the cipher's other half

Choice Made
Kill the rival and take the letter, or ally with the rival to bargain collectively with the Hollow Star.
Impact

Killing: she gains Shadow Portal refinement (120 ft., 2/day) and a permanent +2 to initiative, but the star marks her as its sole accountable agent โ€” failed rituals now cost her maximum hit points (reduce her HP total by 5). Allying: she gains a contact network (advantage on Deception and Investigation in frontier settlements) but shares her patron's favor, weakening Dark One's Blessing to Charisma modifier only.

Major Decision

Context

The ritual fails and the shrine collapses

Choice Made
Fight to the death as doctrine demands, or surrender and offer information about the Hollow Star in exchange for her life.
Impact

Fighting to the death: her body releases a final surge โ€” the Ember Sigil is unharmed and the letter recovered, but the star's dying curse gives her a lingering presence (she may return as a haunt in later acts). Surrendering: she becomes an interrogated asset, revealing the Ashen Eye Charm's origin and one location tied to the Vault of the Unseen, but she permanently loses her spell slots above 1st level as the star strips its gifts, making her a broken, bitter prisoner or reluctant guide.

Ally

Bugbear 'Karrash the Patient'

Relationship enforcer and confidant
Influence 8/10
Loyalty 8/10

Shared History

Karrash was a mercenary bodyguard abandoned by his employers after a botched caravan job in the Skarn Hills, left wounded in a ravine where Nera found him during one of her solitary vigils. She healed him without asking payment, an act of genuine kindness that confused him as much as it moved him. He followed her, first as debt, then as devotion, and is the only servant she treats as a person rather than a tool.

Karrash knows she sings hymns to the goblins at night and has never told anyone. He guards the shrine's inner door and will fight to the death for her โ€” but he has begun asking questions about what happens after the Eye opens, and Nera's evasive answers have planted the first seed of doubt in her most loyal blade.

Potential Breaking Points

  • If he learns the Eye means the end of his kind as well as hers

Enemy

Mayor Elara Voss of Thornwell

Threat Level 6/10
Conflict Type ideological_and_personal

Personal Stakes

Elara and Nera are mirror images: two women of faith who chose duty to a frontier town, one through a mayor's chain and one through a star's promise. They knew each other years ago when Nera served the mission chapel near Thornwell โ€” Elara's late husband was cured of marsh-fever by Sister Nera's hands, and the Voss household owed her a debt of gratitude they never got to repay. When the raids began, Elara was the first to suggest, quietly and shamefully, that the coordination looked like someone who knew the frontier's defenses โ€” someone local, someone trusted.

She has been hunting a ghost of a suspicion ever since. For Nera, Thornwell's mayor is the embodiment of the life she refused: small virtues, small salvations, a town that will die anyway. Breaking Thornwell means proving her choice was right, and breaking Elara specifically โ€” perhaps by revealing who the cultist is โ€” would be the final amputation of her old self. Elara, should she learn the truth, will carry the guilt of having once vouched for the woman driving the raids to her grave or to Nera's throat.

Possible Resolutions

  • Nera can be exposed to Elara, turning the town's resources against the cult
  • Nera can destroy Elara's credibility before the party connects them
  • The two women could confront each other directly at the shrine, with the party as witness

Faction

The Cult of the Ashen Eye

Standing 7/10

Influence

Nera is the cult's sole priestess and organizer on the frontier, but she is far from its origin. The Cult of the Ashen Eye recruited her โ€” not the reverse โ€” through the sealed folio, the dreams, and the hooded messenger who delivered her letter in black wax. The cult's wider structure is unknown to her; she knows only that other cells exist ('the Whisperer has other mouths'), that the Hollow Star communicates selectively and never explains, and that agents who fail are simply never mentioned again.

Her influence within her own cell is absolute: the goblins and orcs worship her as the Whisperer's hand, and Karrash would die for her. But her influence ends at the shrine's edge. She cannot command reinforcements, cannot question doctrine, and cannot refuse an order from the letter. This tension โ€” total local authority, zero institutional security โ€” defines her strategic thinking. She hoards information, caches supplies the cult doesn't know about, and quietly prepares escape routes her orders don't sanction.

Her greatest fear within the faction is not punishment but replacement: the second letter quest exists because she has deduced that a rival agent is being cultivated, and she intends to survive the star's pruning.

Obligations

  • Complete the ritual and return the Ember Sigil
  • Maintain secrecy about the shrine
  • Tithe captives and offerings

Benefits

  • Ritual knowledge and patron magic
  • A loyal fighting force of humanoids
  • Sanctuary in the Skarn Mine
