Clot: A Yore and Gander miner who catches the black glint Bruce throws from the doomed skiff. He escapes the aquifer and flees into the caldera after Randy is struck down, but his immediate fate remains unknown.
Dolph: A powerful but dim-witted miner who helps the trapped workers reach the aquifer. A guard kills him with an oar during the fight for the last skiffs.
Boric: A heavily armored miner who cannot swim. He is lost when the aquifer creature pulls his skiff beneath the water.
Bruce: A clumsy miner who secretly steals a black glint from the restricted mine. As the aquifer creature takes his boat, he throws the stone to the surviving skiff.
Randy: One of the two miners who reaches the far side of the aquifer. A Yore and Gander guard knocks him unconscious as the company attempts to detain the survivors.
Mortis: A comparatively sympathetic Yore and Gander foreman who leads the trapped miners through the company's restricted operation. He is grievously wounded by a masked guard and left behind during the escape.
Piccolo: A young barrel loader working to pay his father's inherited debt. He survives the destruction of the galleon and earns passage away from the Shattered Isles after a company investigation.
Chowder: A port guard who attempts to stop the freedom fighters. His war hammer strikes a firebomb and burns him alive upon the ship.
Valk: A diligent barrel loader who has secretly prepared an escape bunker with Spooner. He avoids the burning galleon by retreating there.
Rose: A warehouse worker who refuses to join the rebellion and runs to warn the ship's captain. The failed response leaves her in company custody.
Teddy: A worker who helps the freedom fighters burn the galleon and is accepted into their movement.
Spooner: A survivalist convinced that the end of the world is approaching. He withdraws to a hidden bunker during the attack and intends to stow away to Gavra afterward.
Flick: A Birkenstock thief who steals offerings during the Festival of Drowning. The Tangled One's song draws him into the sea, where drowned women seize him.
Randall: A former fisherman who surrenders his family's trident during the festival. He swims after Flick and is dragged beneath the water with him.
Walter: A seventy-four-year-old former servant who earned his freedom and became an author. He witnesses the deaths at the festival and recognizes the darkness surrounding the returned bodies as ancient magic.

Nimble: A dance instructor who leads students through the festival parade. He survives the drownings and remains in Birkenstock.
Aizen: A Velpa agent leading the black-glint shipment toward the port. He hides a spreading illness so he can collect his payment and provide for his family, but a Lightless kills him during the eclipse.
Brimley: An elderly new devotee of Eth who joins the covert caravan. When Eth's light fails during the eclipse, he reluctantly invokes Azuron and briefly burns one of the Lightless.
Borgak: A masked mine worker who joins the covert caravan. He hides inside a roadside supply shelter but is engulfed and suffocated by a Lightless.
El: A proud, secret magic user traveling with Aizen. Her attempt to pull a Lightless into view ends with the creature tearing off her head.
Ferb: A caravan guard who quietly worships Azuron instead of Eth. Her divine light turns gold, expands against the eclipse, and protects the remaining travelers until Lunaris returns.
Ginny: A secretive worker from Gavra who survives the attack by hiding inside a roadside supply shelter. She returns with armor and helps the survivors leave the massacre.
Rue: Touches the Veyan door within Ephthalas and chooses his companions at the same moment the Sarexian Eclipse releases the Lightless from the black-glint shipment.
Eth: The Goddess of New Beginnings worshipped throughout the Shattered Isles and Gavra. Islanders believe offerings made in her name protect them from the Tangled One and allow them to enter a renewed life.
The Tangled One: A feared presence beneath the sea whose song calls people into the water. During the festival, drowned women associated with her exchange Flick and Randall for bodies that appear to have been dead for days.
Azuron: A god invoked privately by Ferb. His golden light withstands the Sarexian Eclipse and repels the Lightless when the region's dominant worship of Eth offers no protection.
Lunaris: The Goddess of the Pale Moon and the moon itself. Her light vanishes during the eclipse and returns in time to drive the Lightless from the road.
Festival of Drowning: A celebration of remembrance and renewal dedicated to Eth. Participants symbolically drown their former lives by surrendering cherished objects, unwanted ideas, and hopes upon the water.
Velpa Trading Company: The dominant company of the Shattered Isles. It controls the colony and its glint mines, conceals the danger of black glints, and commissions their covert transport to Gavra when workers begin falling ill.
Yore and Gander: A mining and shipping company identified by an ouroboros. Its masked guards protect the black-glint operation, enforce secrecy, and treat the lives of its indebted laborers as expendable.
Freedom Fighters: Black-clad rebels who attack a Yore and Gander galleon with firebombs. They destroy the ship as an act against company profits and accept Teddy into their movement.
Indentured Laborers: The principal workforce of the Shattered Isles. Prison sentences and unpaid debts can pass from parents to children, creating generations of workers who rarely escape the colony.
Lightless: Faceless humanoid creatures made of living black shadow. They consume light, move through weapons and barriers like liquid, and become fully active when the Sarexian Eclipse darkens the world.
Aquifer Creature: An unidentified predator with a broad face, barbed tentacles, small grasping hands, and a tooth-filled maw. It overturns the miners' skiff and drags several escapees beneath the underground lake.
Charybden: A legendary tentacled sea creature feared around the Shattered Isles and represented by a large festival puppet. Islanders warn that Charybdens can take travelers attempting to cross the cold waters.
Drowned Women: Bloated, corpse-like figures with seaweed hair that appear beneath Birkenstock. They seize Flick and Randall while speaking of sacrifices for those who will be saved.
Glint: A valuable mineral containing tangible light and the foundation of the Shattered Isles' mining economy.
Black Glint: A tainted form of glint that resembles black coal or glass after its light has been removed. It burns Clot's hand, is linked to illness, and appears connected to the Lightless emerging from the sealed cargo.
Black-Glint Barrels: Iron-reinforced containers marked with Yore and Gander's ouroboros. They are hidden in the restricted mine and later transported toward Gavra until they rupture during the eclipse.
Mining Masks: Gas masks worn by the guards and trusted workers within Yore and Gander's secret mine. They imply that the company already recognizes an environmental or infectious danger underground.
Sarexian Eclipse: The alignment in which Sarexis obscures the light of Lunaris and the wider sky. Ordinary flames fail, divine magic weakens, and the Lightless are able to move openly through complete darkness.
The Tangled One's Song: A supernatural call rising from the sea during the Festival of Drowning. It creates thirst, confusion, and compulsion before leading its victims into the depths.
Lightless Hunger: The shadow creatures suppress torches and spells as though feeding upon their light. White divine light barely survives, while Azuron's golden light burns and repels them.
Black-Glint Corruption: A poorly understood contamination associated with drained glints, whispered voices, physical illness, and the living shadows released from the caravan.
The Shattered Isles: A cold archipelago southwest of Scarsden where the Velpa Trading Company controls mining, shipping, and civic life through a colony of indebted laborers and prisoners.
Yore and Gander Mine: A caldera mine containing glint deposits, restricted tunnels, sealed black-glint barrels, masked guards, and an aquifer used as an emergency route to the surface.
Birkenstock: A small fishing town upon the Shattered Isles where the Festival of Drowning is celebrated. Flick and Randall vanish beneath its waters before returning unnaturally decayed.
Gavra: The capital of Scarsden and headquarters of the Velpa Trading Company. The black-glint shipment is intended for research there, and Piccolo receives passage back after surviving the dock attack.
Underground Aquifer: A vast, lightless lake beneath the mine. Skiffs provide a concealed route between shafts, but a tentacled creature hunts within its waters.
Inherited Debt of the Shattered Isles: Prisoners and indentured servants are promised release after repaying what they owe, but remaining debts pass to their children and keep families trapped for generations.
Black-Glint Crisis: Yore and Gander has secretly mined and stored glints stripped of light. The crisis becomes impossible to contain when workers fall ill and the cargo releases the Lightless during the eclipse.
Piccolo's Freedom: After eight years loading barrels to pay his father's debt, Piccolo survives the galleon attack and becomes one of the rare workers permitted to leave the Shattered Isles.
Emergence of the Lightless: The Sarexian Eclipse allows the black-glint shipment to break apart and releases creatures that consume light, kill most of Aizen's caravan, and retreat into ordinary shadows when Lunaris returns.
