Symbol
A silver crescent crossed by a black tar brush.
The village priest has locked the sick children inside the hall for their own safety. At moonrise, pitch-black handprints appear along the shuttered windows, but no footprints mark the new snow. A smuggler has stolen the medicine the children need. The villagers know who did it. None will say his name while the waning moon is visible.
Rahko is a Finnish moon spirit who stains the moon black. His brush covers a truth that someone desperately wishes to hide. In the old forests he is invoked by thieves and desperate parents alike. A person who bargains for darkness can sometimes save a life. They can also give a killer the only hour he needs.
Rahko is not the brother, lover or master of Kuutar. The two belong to different stories of the moon, and neither gains authority over the other merely by sharing the sky.
What Is Happening Right Now?
In the lake-country settlements, the moon has been growing dark three nights too early. Tar burners say that their barrels have become lighter without being opened, and the old hunters swear that every path under the trees has shifted a few paces west. The nightly veil is not an eclipse: the missing light can be found gleaming beneath the skin of a single black pond.
A band of smugglers calls itself the Moon’s Workmen and claims Rahko has given them leave to carry people across closed borders. Their rescued passengers are real; so are the captives they sell to pay for that passage. Meanwhile, an elderly midwife has begun painting black crescents on the doors of families awaiting a dangerous birth. Her wards work, but each household protected loses a memory of the person who helped it.
Rahko has neither blessed all of these acts nor stopped them. He is watching to see which petitioner will name what they have concealed.
The Blackening of the Moon
A small dark mark first appears on the white moon, no larger than the head of a brush. As the night wears on it spreads across the face like tar on polished silver. Some elders say a man climbed a ladder toward the light to silence it while stealing; others tell of a soul made to work at the moon until it is clean again. Among the forest families, these are not rival certainties but explanations whispered on different nights.
Rahko carries a bucket that is never empty while someone living hides a necessary truth. The pitch does not drip upon the ground. It falls instead onto words that people meant to speak. A truthful confession can strip away one layer of the black; a false oath paints it on again.
His true shape is uncertain. He usually appears as a gaunt, wind-cut traveller in wool and fur, carrying a long brush and a battered pail. Sometimes the bucket hangs from a ladder suspended in the night air. At other times a solitary silhouette is visible on the moon itself, no larger than a child’s thumb held up against the sky.
Moonlight is not inherently righteous, and darkness is not inherently wicked. Rahko takes pleasure in the instant when a watcher can no longer distinguish the hunted from the hunter. A kind traveller may pray for a concealing cloud; a murderer may ask for the same. Rahko knows the difference and often refuses to disclose it until the bargain has done its work.
Moonlight, Other Powers and Mortal Bargains
Kuutar gives gold and keeps the bright craft of the moon; Päivätär belongs to the high day and the luminous thread. Rahko neither commands nor descends from either maiden. He is an uneasy counterpart to their visible gifts: when a necklace is hidden, when a song goes unrecorded, or when a witness refuses the king’s reward, his power is near. These crossings are stories for the campaign, not claims of an ancient divine genealogy.
A bargain made with Rahko always has three parts: a truth kept dark, a person sheltered or endangered by that darkness, and a debt called due when the moon is clear again. The spirit dislikes careless cruelty more than theft. His punishments are not moral judgements so much as demonstrations: people who hide another’s face may wake to find nobody can remember their own.
The Moon’s Workmen wear blackened wooden medallions. The Quiet Midwives make warding signs with ash rather than tar. Neither group speaks for every servant of Rahko; the spirit has no reliable priestly hierarchy.
The Tar-House of the Waning Moon
Beyond a still lake where the pines cast shadows without starlight, a narrow ladder rises into the sky. Each rung is damp with old pitch. At the top stands the Tar-House: a long, low workshop with a roof of black boards and a silver basin that reflects every moon except the one overhead. Its doors open only onto the hour before moonset.
Visitors find empty hooks for buckets they have not yet carried and shelves of sealed glass jars containing the last words people did not speak. The floor creaks under a visitor who conceals a name. Some doors open onto the road the guest has fled; others open onto the place they most fear being seen.
Estate effects. Within the Tar-House, mundane light is reduced to dim light and no creature can use ordinary darkvision to see through Rahko’s true eclipse veil. Every confession spoken without coercion makes one lantern burn clearly for one hour. A character who steals a sealed jar learns the name inside but loses a cherished memory until the jar is returned or broken at moonrise.
Regional signs. Within several miles of a place Rahko visits, moons in standing water may appear half covered with ink, tar buckets develop a skin of silver, and travellers sometimes discover that they have passed the same birch tree twice. These effects disappear when he departs, though any bargains he made remain binding.
Rites, Offerings and Followers
His callers meet at the edge of settlements, not in public temples. They offer pine pitch, the unused end of a candle, an empty bucket, or the name of a wrong they have finally decided to admit. A door marked in ash is a request for one night without pursuit, not permission to harm those behind it.
The oldest watchers keep a lamp burning through the final sliver of the moon. They do not pray for more light. They pray to know when concealment has become complicity. When a fugitive is protected from a tyrant, Rahko may leave a black thumbprint on the lintel as a pledge. When a hidden murderer is welcomed without question, the same mark can be a warning.
Adventurers who carry his sign are expected to choose, sooner or later, whom their secrecy is saving. A good-aligned follower can serve Rahko by guarding people from predatory scrutiny; an evil follower may attempt to pervert the very same custom into cover for cruelty. The spirit is not an outsider embodying absolute cosmic evil.
Divine Gifts
Rahko grants concealment, misdirection and the chance to expose a hidden witness. His priests guard refuges, carry messages through moonless woods and demand that each petitioner name the person their secrecy protects. The rules below include his optional Moon-Shadow domain and its spells.
Boons and the Cost of Darkness
- Hidden Crossing. A single pursued creature may follow the wrong shadow for one hour, confounding mundane tracking. In return it must speak one truth to the person most harmed by its silence before the next full moon.
- Silver in the Pitch. A seeker who asks the right question can see the last thing a concealed witness saw, reflected in a dark pond. The vision omits whatever the seeker most wishes to hear.
- Black Candle. A candle blessed at the waning crescent extinguishes itself when someone nearby lies about an immediate threat. It cannot tell whether a lie was told from fear or malice.
- Last Light. Rahko can uncover the face of a false moon, breaking one glamour covering a settlement. He may demand the public confession of the person who commissioned it.
Adventure Hooks
- The Medicine Road. Smugglers have used Rahko’s darkness to take fever medicine into a besieged valley. Their leader now insists that the same passage can be used to transport prisoners. Recover the stolen ledger before both kinds of traveller disappear.
- The Ladder in the Mire. Every new moon a ladder rises from a bog. Two children climb it to reclaim their mother’s stolen name. The last three who followed the ladder returned unable to recognise their families.
- The Tarred Bride. A noble bride vanishes from beneath a lanterned procession. Her shadow remains, arguing that she chose to leave. The shadow may be telling the truth; her father has hired a company to silence it.
- Moon Under Glass. A sorcerer has bought the blackness of one moon and stored it in a mirror. With no night left to hide the refugees he promised to protect, a village must decide whether to break the mirror and expose the sorcerer’s other crimes.
- The Last Jar. The Tar-House holds the unspoken confession of a respected judge. Opening it will free a condemned prisoner, but the judge’s guards have vowed to drown the only witness.
Travel, Omens and Dangers
A traveller who sees black water reflecting a silver crescent should avoid making promises until dawn. The reflection may mark an entry to Rahko’s estate, a dangerous threshold for people carrying stolen names or false testimony. Lanterns remain useful away from the true eclipse veil, and ordinary darkness is not a supernatural curse.
His agents offer a dangerous convenience: an hour in which nobody can see you. The price may allow somebody else to become invisible to justice. Before accepting, travellers must decide whose safety matters and who will bear the debt.
Game Statistics
Rahko’s manifested body can be driven from the world, but his defeat leaves the Tar-House and its debts intact. The Moon-Darkener returns at the next new moon unless the stolen light is restored and the truth behind his latest bargain is spoken freely.

Traits
Legendary Resistance (3/Day). If Rahko fails a saving throw, he can choose to succeed instead.
Moon’s Black Face. Magical dim light surrounds Rahko in a 30-foot Emanation. He sees normally through it. A hostile creature that starts its turn there must succeed on a DC 25 Wisdom saving throw or have Disadvantage on its next attack roll before the end of its turn. This aura is suppressed until the end of Rahko’s next turn if he takes Radiant damage.
Unseen Debt. Rahko knows when a creature within 120 feet knowingly makes a false statement, although he cannot discern the truth without further magic.
Actions
Multiattack. Rahko makes three Black-Pitch attacks.
Black-Pitch. Ranged Attack Roll: +17, range 120 ft. One target. Hit: 32 (4d10 + 10) Necrotic damage, and the target cannot benefit from being Invisible until the start of Rahko’s next turn.
Moon-Split (Recharge 5–6). A wave of moon-black resin pours through a 60-foot Cone. Each creature of Rahko’s choice in the area makes a DC 25 Dexterity saving throw, taking 72 (16d8) Necrotic damage on a failed save, or half as much on a successful one. Bright light in the cone becomes dim light until the end of Rahko’s next turn.
Spellcasting. Rahko casts the following spells, requiring no Material components (spell save DC 25): At Will: darkness, disguise self, fog cloud; 3/Day Each: greater invisibility, mislead, nondetection; 1/Day Each: foresight, plane shift (self only).
Bonus Actions
Step Between Shadows. Rahko teleports up to 60 feet to an unoccupied space he can see in dim light or darkness.
Reactions
Blacken the Lantern (1/Round). When a creature Rahko can see within 60 feet makes an attack roll against him, before the roll is resolved, Rahko imposes Disadvantage on that attack roll, potentially making it miss. The attacker must be able to see Rahko.
Legendary Actions (3/Round)
Rahko can take three Legendary Actions, choosing from the options below. Only one option can be used at a time and only at the end of another creature’s turn. Rahko regains spent uses at the start of his turn.
Brushstroke. Rahko makes one Black-Pitch attack.
Moon-Step. Rahko uses Step Between Shadows.
Seal the Secret (Costs 2 Actions). One creature Rahko can see within 60 feet makes a DC 25 Charisma saving throw; on a failure, it cannot speak above a whisper or cast spells with Verbal components until the end of its next turn.

Special Abilities
Moon-Pitch (Su). As a standard action, Rahko fires a supernatural ray with a range increment of 30 feet; it deals the listed cold damage. A struck creature leaves a luminous trail visible to Rahko for 1 round, negating its invisibility against him. This is a supernatural attack. His attack and damage rolls gain +1 within 30 feet from Point-Blank Shot.
Moon-Split (Su). Once every 1d4 rounds, Rahko casts a 60-foot cone of black moonlight, dealing 20d6 cold damage (Reflex DC 40 half); on a failed save the victim is also blinded for 1 round. The save DC is Charisma-based (10 + half Rahko’s Hit Dice + his Charisma modifier).
Seal the Secret (Su). Three times per day, one creature within 60 feet must succeed on a DC 40 Will save or be unable to speak or use verbal spell components for 1 round. This is a mind-affecting curse; the save DC is Charisma-based.
Moon-Veil (Su). Rahko is continuously surrounded by a 30-foot-radius dim haze that grants him concealment (20% miss chance). A successful targeted dispel magic check against caster level 24 suppresses it for 1 round. It does not negate true seeing.
Lunar Witness (Su). Rahko automatically notices knowingly false statements made within 120 feet but learns no further truth by this sense alone.
Moon-Shadow Domain
Granted Powers: You can draw a veil of moon-dark pitch around those you shelter. This is an original domain available to clerics of Rahko.
Pitch-Ward (Su): As a standard action, grant one willing creature within 30 feet concealment (20% miss chance) for 1 round. You can use this power a number of times per day equal to 3 + your Wisdom modifier.
Veil of the Refuge (Su): At 8th level, you can spend two uses of Pitch-Ward as a standard action to grant its concealment to yourself and all willing allies within 10 feet for 1 round. Neither power grants invisibility or blocks true seeing.

Special Abilities
Moon-Pitch (Su): As a standard action, Rahko makes one supernatural ray attack out to 150 feet, dealing 6d10+12 cold damage. A struck opponent cannot use invisibility to hide from Rahko for 1 round. This ability does not gain iterative attacks. Point Blank Shot grants +1 to its attack and damage rolls within 30 feet.

Moon-Veil (Su): Rahko has concealment (20% miss chance) in dim light from a supernatural haze extending 30 feet; targeted dispelling against caster level 24 suppresses it for one round.
Lunar Witness (Su): He senses deliberate untruths spoken within 120 feet without learning the underlying facts.

Dodge: At the start of each turn, Rahko designates one opponent he can see; his AC against that opponent is 42, touch 31. This bonus is lost when he loses his Dexterity bonus to AC.

Sources, Interpretation and Credits
The oldest named written witness is Mikael Agricola’s list of traditional Finnish powers in the preface to his Dauidin Psalttari (1551), which associates Rachkoi with darkening the moon. Later oral traditions vary: some tell of a thief covering the moon with tar, while others link the lunar figure to recurrent work, punishment or the restoration of light. The interpretation here does not assume that every tale describes the same being.
These records are later than the campaign’s default historical present. The 1551 poem serves as a modern reference for the game’s folklore reconstruction, not a book physically circulating in the setting.
Historical names and the theme of moon-darkening are sourced folklore. The Tar-House, Moon’s Workmen, Quiet Midwives, adventures, alignment, domains, magic, statistics and emblem are original campaign inventions. They should not be mistaken for documented ancient rites or genealogy.
