The mop was heavier than it should have been.
Caelus Vane dragged it across the marble floor of the Orbital Authority's thirty-second floor, leaving a wet trail that would dry invisible within minutes. The marble was Thessalian white, imported from quarries that no longer existed—swallowed during the Gravity Fall along with the six hundred thousand people who'd lived above them. The OA liked its floors pristine. It helped them forget what lay beneath.
Cael didn't forget. He couldn't. Every morning he clocked in at 5:47 AM, thirteen minutes before the first Planetary Orbiters arrived, and every morning he felt the weight of the building pressing down through thirty-two floors of reinforced gravitite steel, through the marble, through the wet mop, and into his hands. Four hundred meters of authority, built on a graveyard.
"Vane." The voice crackled through his earpiece. Supervisor Tellus, who managed the janitorial Dwarfs from a desk on the fourth floor and hadn't touched a mop in eleven years. "You're behind on thirty-two. The Magistra's wing needs to be finished before seven."
"Copy," Cael said. He didn't say that the Magistra's wing was always finished before seven. He didn't say that he'd been cleaning this floor for fourteen months and knew its rhythm better than Tellus knew his own wife's name. He said "copy" and kept mopping, because that was what Dwarfs did. They copied. They complied. They became invisible.
The elevator chimed.
Cael stepped aside without looking up—a reflex trained into every service-class Dwarf before they turned twelve. You heard the chime, you moved. You pressed yourself against the wall, you lowered your eyes, and you waited for the gravity to pass. Because when a Planetary Orbiter walked by, you felt it. Not metaphorically. Literally. Their Cores radiated gravitational fields that bent the air, made your teeth ache, pressed against your chest like a hand pushing you down. The stronger the Orbiter, the heavier the pressure.
This one was heavy.
Cael kept his eyes on the floor as boots crossed his peripheral vision—black leather, magnetized soles, the silver insignia of a senior enforcer stitched into the ankle. Eight orbits, probably. Maybe nine. The air thickened as the enforcer passed, and Cael felt his own meager gravity field compress, shrinking inward like a dog tucking its tail. His four orbits—if you could call them that—flickered weakly in his chest. Passive Sight that could barely read surface emotions. Muffled Hearing that caught echoes but not words. Dull Touch that sensed texture but not truth. Negligible Weight manipulation that could lighten a mop by a few grams.
Four orbits. The minimum to be classified as an Orbiter at all. One less and he'd be a Null—no Core activity, no registration, no protection under the Orbital Compact. Four orbits made him a Dwarf: registered, tracked, employed in menial labor, and reminded daily that he existed at the bottom of a hierarchy built on gravitational potential.
The enforcer turned the corner without acknowledging him. Of course.
Cael wrung the mop into the bucket. The water was gray with dust that had settled from the upper floors—particulate matter carried down by the building's gravity recyclers. Even the dust in this place was hierarchical, falling from the offices of twelve-orbit Magistras down to the basement where Dwarfs scrubbed it away. He'd once calculated that he cleaned approximately three kilograms of descended dust per week. Three kilograms of the powerful, rendered into particles, washed into drains by the powerless.
There was a poetry to it that he tried not to think about.
By 6:30, he'd finished the Magistra's wing and moved to the eastern corridor—a long stretch of floor-to-ceiling windows overlooking Gravitas. The city sprawled beneath the morning haze like a blueprint someone had crumpled and tried to smooth flat again. Towers of gravitite steel rose in concentric rings around the Authority building, their surfaces catching the first light in flashes of cold silver. Between them, elevated transit lines hummed with early commuters—mostly mid-level Orbiters heading to administrative posts, their gravity fields creating subtle distortions in the air that made the train cars shimmer like heat mirages.
Below the transit lines, the ground level. Shops, markets, residential blocks—the domain of low-orbit citizens and registered Dwarfs. Below that, visible only as shadows between foundation pillars, the undercity. Cael had never been down there. The undercity was where Unregistered Orbiters hid, where criminals ran black-market Core modifications, where people who'd been Demoted past Dwarf status went to disappear. The OA pretended it didn't exist. Everyone else pretended they didn't know.
Cael pressed his forehead against the cold glass. Somewhere out there, in one of those residential blocks, was the apartment the OA had assigned him when he aged out of the state orphanage at fifteen. Two rooms, a kitchen alcove, a bathroom with a shower that ran cold after four minutes. He'd lived there for two years and it still didn't feel like his. Nothing did. The Gravity Fall had taken his parents, his home, his childhood, and most of his Core's capacity in a single afternoon. What it left behind was a boy-shaped absence—a Dwarf who cleaned floors and tried not to remember that he'd once been something more.
His reflection stared back at him from the glass: seventeen in three days, though he looked older. Dark hair that he cut himself with kitchen scissors. Angular face, too thin, the kind of thinness that came from eating enough to survive but never enough to feel full. Gray eyes—unusual in Gravitas, where most people carried the brown or amber common to families with strong orbital lineage. Gray was the color of Cores that had been damaged. The color of potential that had collapsed inward.
"Vane. Thirty-third floor needs a spill cleanup. Sector C."
"Copy."
He gathered his supplies and moved toward the service elevator, passing the portraits that lined the eastern corridor. Magistras, past and present, painted in oils and framed in gravitite. Their orbital counts gleamed in gold beneath each portrait—ten, eleven, twelve. The current Magistra, Sera Kane, held the record: twelve orbits, perfectly synchronized, zero failed missions in nine years of service. Her portrait showed a woman in her mid-thirties, dark-skinned, sharp-featured, with eyes that seemed to follow you down the hallway. Cael had cleaned the glass over her portrait six hundred and twelve times. He'd never met her in person.
He wondered, sometimes, what it felt like to have twelve orbits. To feel the world bend around you. To know that gravity itself was your instrument, your weapon, your proof of worth. He imagined it was warm. He imagined it filled the spaces inside you that ordinary life left empty.
Then he imagined nothing, because imagining made the weight heavier, and the mop was heavy enough already.
Lunch was thirty minutes on the roof.
Technically, Dwarfs weren't allowed above the fortieth floor, but the roof access door's lock had been broken for two years and no one had bothered to fix it. Why would they? No Dwarf would dare climb fifty-two flights of stairs for a view. Except Cael, who'd been doing it three times a week since he started working here, because the roof was the one place in the tower where no one looked down at him.
He sat on the concrete lip of the maintenance platform, legs dangling over four hundred meters of empty air, and ate his lunch—a protein bar and an apple he'd saved from yesterday's ration. The wind was sharp this high up, carrying the faint hum of gravity recyclers from neighboring towers. Below, the city moved in its careful choreography: Orbiters flowing through the streets like currents in a river, their gravity fields creating invisible channels that Dwarfs instinctively avoided.
Cael bit into the apple and watched a patrol of OA enforcers cross the central plaza, their combined gravity fields strong enough to ripple the fountain water from thirty meters away. Six orbits each, minimum. Walking advertisements for the Authority's power. They moved in formation, synchronized, their orbits humming in visible harmony—faint rings of light that orbited their bodies like personal solar systems.
He looked at his own hands. If he concentrated, he could feel his four orbits—weak, sluggish things that rotated around his Core like dying satellites. Sight, Hearing, Touch, Weight. The sensory orbits, the ones even children developed first. His had never progressed beyond childhood levels. The OA doctors said his Core was "compromised"—cracked during the Gravity Fall, healed wrong, permanently limited. They'd stamped his file with the Dwarf classification and moved on.
Sometimes, late at night, he felt something else. Something deeper than the four orbits, buried beneath the scar tissue of his damaged Core. A vibration. A heat. Like an engine idling in a locked room—present but unreachable. He'd mentioned it once to an OA physician during his annual check. The physician had noted "phantom orbital sensation—common in trauma-damaged Cores" and prescribed a sedative.
Cael had thrown the sedative away. The vibration wasn't phantom. It was patient.
He finished his apple and tossed the core into the wind. It fell, caught by the building's gravitational envelope, and curved gently toward the waste collectors on the fifteenth floor. Even garbage found its orbit in this city.
Three more hours until his shift ended. Then the walk home, the cold apartment, the silence that pressed against his ears like water. Tomorrow, the same. The day after, the same. Until he was old enough to be reassigned to a factory, or a mine, or one of the reclamation zones outside the city where Dwarfs did the work that Orbiters' gravity fields made impossible.
He stood, brushed dust from his uniform—gray coveralls with a Dwarf registration number stitched into the breast: DRF-2006-0213. The number followed him everywhere. It was on his apartment door, his ration card, his medical file. It was the first thing anyone saw when they looked at him, and usually the last, because after the number there was nothing worth seeing.
Caelus Vane, Dwarf Class, four orbits, zero combat capability, zero strategic value.
He walked back to the service elevator, and the roof door closed behind him with a sound like a sigh.
