At the table

Voice

His voice has a dry, faintly rasping edge, like air passing through a narrow chimney. Before speaking he often takes two short breaths through his nose, an old habit from working in smoke. He does not sing or boom; his consonants land cleanly, and when alarmed his words come faster and more technical, as if naming each hazard could contain it.

He speaks in measured, workmanlike phrases, often pausing for a double intake of breath that sounds like a bellows being tested. His vocabulary is shaped by years among chimneys and rooftops: rooms have drafts, arguments have backdrafts, and a bad decision is a blocked flue. He clips hard consonants and tends to finish a sentence only after deciding whether it is safe to say aloud.

Speech patterns

Uses precise words for heat, airflow, and exits even when discussing relationships.
Asks people where they would go if the room caught fire, then watches their answer more closely than their face.
Calls dangerous magic 'a bad draft' and describes bargains as 'ventilation problems.'
When apologizing, names the specific thing he did wrong rather than asking to be forgiven.

How to play them

He is guarded but useful, offering a real service before negotiating. Earn his trust by protecting bystanders and being candid about risks. He responds poorly to threats against children or demands that he reveal private names. If confronted with evidence of his own evasions, he becomes blunt rather than charming.

Goal

Find a way to void or rewrite his pact without transferring its cost to someone else, while keeping Gvantsa from starting a fire that will consume the neighborhood she claims to defend.

Motivation

Keep the people around him from becoming fuel for another person's ambition, and find a way to make his pact answerable to him rather than the reverse.

Secret · GM only

Appearance

Uldek has ash-grey skin with a dry, pumice-like texture at his temples and a faint shine across his nose, as if smoke has polished it. His curved obsidian horns sweep back close to his skull, their ridged surfaces catching light like chipped glass. Ember-orange eyes glow most clearly in shadow. He walks with the careful, heel-first tread of someone accustomed to crossing creaking rooftops, and smoke-like wisps curl from the high collar of his crimson robes even in still air. The unexpected detail: he keeps a tiny, brightly painted wooden bird tucked into his belt, a toy he is painstakingly repairing for a child in his neighborhood.

Clothing

Dark crimson robes reinforced at the elbows and hem, with a smoke-grey lining and a high collar that hides a small brass charm. He wears a practical leather harness beneath them, soot-dark gloves, and soft boots with narrow soles.

Body language

He keeps his shoulders angled toward the nearest exit and rarely stands with his back to a hearth. His hands make small, exact gestures, as though measuring a flue; under pressure he presses his thumb against the wooden bird in his belt.

Distinguishing features

Obsidian horns sweep backward in ridged, glassy arcs.
A thin wreath of smoke-like wisps sometimes clings to his collar, even outdoors.
His eyes glow ember-orange in dim light.
A tiny painted wooden bird, chipped at one wing, rides at his belt.

Personality

12 traits and drives

Uldek can be generous with his time and merciless with information. Around frightened people he becomes patient and practical, placing himself between them and danger; among officials he is dry, suspicious, and willing to humiliate a bully with a precisely chosen fact. When guilt catches up with him, he tries to solve everyone's problems without asking what they want. He wants to be trusted, yet keeps the very secrets that would make trust possible.

Alignment
Neutral, with a stubborn habit of protecting people who have no leverage over him

Quirks

Tests the air by breathing in through his nose twice before entering a cellar.
Turns cups so their handles point toward the nearest exit.
Names the flames in a hearth after people who have annoyed him, then insists it is a safety mnemonic.
Taps a rhythm of four short beats on any wooden door before opening it.
Carries a small tin of bright paint and touches up the wooden bird whenever a conversation becomes uncomfortable.

Habits

At a new address he studies the chimney, windows, and nearest water source before greeting anyone.
He offers practical help before asking for information, but remembers every debt and favor with unsettling precision.
After a spell, he checks the air for lingering smoke as if testing whether a room is safe.
When exhausted, he stops making eye contact and counts the floorboards under his breath.

Traits · 3

He can calmly explain a dangerous ritual while quietly setting a chair between a frightened stranger and the door.
He despises coercion but will manipulate a conversation if he thinks it will prevent a worse outcome.
With children he is unexpectedly playful, though he pretends their jokes are merely useful observations.

Flaws · 3

He treats trust as a debt that must be repaid, making kindness difficult to accept.
He withholds dangerous truths until he has already made decisions for other people.
His hatred of fire used against the powerless can make him reckless and easy to provoke.

Fears · 3

Another fire in which he must choose who to save.
That his patron will demand a child's name as payment.
That his sister's death was not an accident, but a consequence of the bargain he made.

Wants and needs · 3

Needs to learn whether the Cinder Bailiff can be bound by the precise wording of its own bargain.
Wants Gvantsa to abandon her arson plan without turning her over to the authorities.
Needs someone he can tell the truth to without immediately converting the confession into a transaction.

Combat

AC 14 · HP 38 · 30 ft.

Uldek tries to begin at range, using hypnotic pattern to split a group or fireball against clustered enemies when allies are clear. He uses eldritch blast to keep threats away from himself and vulnerable companions, saving a pact slot for counterspell or a decisive attack. He avoids killing if a foe can be driven off, but when an enemy threatens a helpless bystander, his restraint vanishes.

Dark One's Blessing. When Uldek reduces a hostile creature to 0 hit points, he gains 8 temporary hit points.
Eldritch Invocations. Agonizing Blast adds his Charisma modifier to each beam of eldritch blast; Repelling Blast can push a creature hit by a beam up to 10 feet away.
Pact of the Tome. His soot-black book contains three cantrips: guidance, mage hand, and spare the dying. These are at-will pact gifts, not additional warlock spells.
Spellcasting. Charisma is his spellcasting ability, spell save , spell attack bonus +7. He has two 3rd-level pact slots, regained after a short or long rest.

Spells

Eldritch blast (cantrip, evocation). At will. A ranged spell attack that fires two beams at this level; each hit deals force damage. Agonizing Blast and Repelling Blast apply.
Spare the dying (cantrip, necromancy). At will. Uldek can touch a creature and stabilize it if it is dying, without restoring hit points.
Mage hand (cantrip, conjuration). At will. Uldek can create a spectral hand to manipulate objects at a distance, within the spell's limits.
Guidance (cantrip, divination). At will. Uldek can bolster one willing creature's next ability check with a d4, subject to the spell's concentration and duration.
Armor of Agathys (level 1, abjuration). 1st level. Uldek surrounds himself with a warding magical force, setting his AC to 13 + his Dexterity modifier for 8 hours. It does not stack with armor; he normally relies on his studded leather instead.
Misty Step (level 1, conjuration). 1st level. As a bonus action, Uldek can teleport up to 30 feet to a space he can see and become invisible until the start of his next turn or until he attacks or casts a spell.
Mind Sliver (level 2, enchantment). 2nd level. Uldek makes a ranged spell attack against a creature within 120 feet. On a hit, it takes psychic damage and must make a Wisdom saving throw or have disadvantage on its next attack roll before the end of Uldek's next turn.
Fireball (level 3, evocation). 3rd level. Uldek creates a 20-foot-radius sphere of flame at a point within 150 feet. Creatures in the area make a Dexterity saving throw, taking fire damage on a failure or half on a success; flammable unattended objects ignite.
Counterspell (level 3, abjuration). 3rd level. Uldek interrupts a creature he can see within 60 feet that is casting a spell. The spell fails if its level is 3rd or lower; for a higher-level spell, he makes a Charisma check against + the spell's level. He can cast this as an action or, with a pact slot, as his reaction.
Hypnotic Pattern (level 3, illusion). 3rd level. Uldek creates a 30-foot cube of mesmerizing patterns within 120 feet. Each creature in the area that can see the pattern must make a Wisdom saving throw or become charmed and incapacitated, with speed 0, for up to 1 minute. The effect ends for a creature that takes damage or is shaken by another creature's action.
Shadow of Moil (level 3, necromancy). 3rd level. Uldek wreathes himself in shadowy flame for up to 1 minute, concentrating. He has resistance to radiant damage and can see normally in magical and nonmagical darkness. When a creature within 5 feet hits him with an attack, it takes necrotic damage.

Actions

Eldritch Blast. Ranged spell attack: to hit, range 120 ft., one or two beams. Each beam deals force damage on a hit. A creature hit by a beam can be pushed up to 10 feet away from Uldek.
Dagger. Melee or ranged weapon attack: to hit, reach 5 ft. or range 20/60 ft., one target. Hit: piercing damage.
Pact Spellcasting. Uldek spends one 3rd-level pact slot to cast a spell he knows. His common choices are fireball, counterspell, or hypnotic pattern; see spells for details.

Reactions

Hellish Rebuke. When Uldek takes damage from a creature he can see within 60 feet, he can cast hellish rebuke using a 3rd-level pact slot. The attacker makes a Dexterity saving throw, taking fire damage on a failure or half as much on a success. This uses one pact slot.

Services they sell

Rewards they can give

Equipment

  • Soot-dark studded leather (armor)Studded leather beneath his robes; its dark finish and soft construction are practical armor, not a magical defense.

  • Dagger (weapon)A balanced utility blade used for cutting cord and, if cornered, self-defense.

Possessions

Soot-black pact tome
Dagger
Brass flue charm inherited from his mother
Half-repaired wooden bird

Background

Uldek was raised among the furnace lanes of a river city, where his mother repaired chimney flues and his father disappeared into debt. As a boy he learned to read smoke, find hidden passages, and tell which neighbors were awake by the sounds above their ceilings. During a winter fire, he climbed into a burning tenement to guide trapped residents out. The last person he reached was his younger sister, who died before he could get her clear. In the smoke-filled stairwell, he accepted a pact from a fiend who promised him the strength to make sure no one else was helpless in a fire. The pact saved the other residents, but its price was an obligation to collect names and secrets for his patron. Now Uldek works as a discreet occult consultant and fire investigator, quietly diverting the patron's demands away from ordinary people. He is close to a neighborhood toy-maker who knows about the wooden bird, and is being pressed by a former apprentice who wants him to use his magic for political arson.

Role in the story

A wary occult expert and potential ally whose knowledge of fires, roofs, and infernal bargains can help the party investigate a threat. His pact's demands and his former apprentice's plans create a conflict that can become a rescue, negotiation, or moral dilemma.

“As a boy he learned to read smoke, find hidden passages, and tell which neighbors were awake by the sounds above their ceilings.”
