Gravitas had been built to make you look up.
The city's architects—all twelve-orbit Planetary Orbiters—had designed every sightline to draw the eye toward the Orbital Authority tower at its center. Streets radiated outward like spokes from a hub. Buildings increased in height as they approached the core, creating a gravitational funnel of steel and glass that made the tower seem less like a structure and more like an inevitability. You couldn't live in Gravitas without seeing it. You couldn't see it without feeling small.
Cael had stopped feeling small about six months into his employment there. Now he mostly felt tired.
"Thirty-four through thirty-eight today," Tellus said through the earpiece. "Full service. The Deputy Magistra is hosting a delegation from the Northern Provinces and I want those floors pristine. Do not embarrass me, Vane."
"Copy."
He loaded his cart in the basement supply room—mops, solvents, polishing compounds, the handheld gravity scrubber that OA maintenance had issued to janitorial staff with the strict instruction that it was "not a toy, not a weapon, and not to be modified in any way." The scrubber used a tiny gravitite core to generate localized gravity pulses that lifted stains from surfaces. It was the most advanced piece of technology Cael was allowed to touch, and it had less orbital capacity than his left shoe.
He wheeled the cart to the service elevator, keyed in his floor access (Dwarfs were cleared for floors one through forty, service corridors only, no main hallways without escort), and began his ascent.
The tower's internal structure was a study in stratification. Floors one through ten: administration, registration, public services. This was where citizens came to register their orbital development, apply for classification upgrades, report Unregistered activity, or petition for Dwarf assistance programs. The lobbies were grand but impersonal—marble floors, gravitite pillars, holographic displays showing the current orbital census. The air was warm with the combined gravity of hundreds of mid-level Orbiters conducting bureaucratic rituals.
Floors eleven through twenty: enforcement. The OA's military arm. Training halls, armories, tactical planning rooms, and the cells where Unregistered Orbiters were held pending classification or... resolution. Cael had cleaned these floors once, early in his employment. The gravity was heavier here—not from the Orbiters stationed there, but from the gravitite suppression systems built into the walls. The cells were designed to compress an Orbiter's field until their orbits couldn't maintain coherence. Standing near them made Cael's teeth vibrate.
Floors twenty-one through forty: the operational heart. Research laboratories, Core analysis facilities, the vast archives where every registered Orbiter's gravitational signature was stored and catalogued. This was where the OA's real work happened—understanding, quantifying, and controlling orbital power. The researchers here were mostly seven to nine orbits, technical specialists whose gravity fields were precisely calibrated for delicate work. They were polite to Cael in the way people were polite to furniture—acknowledging presence without attributing significance.
Floors forty-one through fifty: the Magistra's domain. Senior leadership, strategic planning, the council chambers where policy was shaped by Orbiters whose gravity fields could bend light. Cael had never been above forty. Dwarfs weren't allowed. The elevator simply wouldn't respond to their keycards.
And the top two floors—fifty-one and fifty-two—were Magistra Sera Kane's personal quarters and office. No one cleaned those floors. Rumor said she maintained them herself, her twelve orbits keeping the space in a state of perpetual order. Rumor also said that anyone who entered uninvited left lighter—that her gravity field stripped orbital capacity from intruders as a defense mechanism. Cael didn't know if this was true. He didn't intend to find out.
Floor thirty-four was a research wing dedicated to Core analysis. The labs were clean rooms—sealed environments where gravitational contamination could corrupt experimental results. Cael's job was to clean the corridors and common areas between labs, not the labs themselves. He'd learned this the hard way in his second week, when he'd accidentally opened a clean room door and triggered a containment alarm that shut down an entire floor for six hours. The lead researcher, a nine-orbit woman named Dr. Pell, had stared at him with the particular horror of someone watching a cockroach walk across a wedding cake.
He mopped the corridor outside Lab 34-C and listened to the sounds filtering through the sealed door. Voices—two researchers discussing something with the intensity that meant either breakthrough or catastrophe.
"—resonance pattern doesn't match any registered signature. It's not a Planet, it's not a Dwarf, it's not even Unregistered. The waveform suggests a capacity we don't have classification for—"
"That's impossible. The classification system accounts for all orbital configurations up to twelve—"
"I know what the system accounts for. I'm telling you what the data shows. Thirteen channels. Active. Stable."
Silence. Then: "Pull that data offline immediately. Lock the file. This goes to the Magistra directly."
Cael's mop paused. Thirteen. The same number that had been rattling around his dreams like a marble in an empty room. He shook it off—coincidence, nothing more—and kept cleaning. The researchers' conversations were none of his business. Nothing in this tower was his business. He was furniture. Furniture didn't eavesdrop.
But furniture didn't dream about numbers, either.
Lunch on the roof. Wind sharp, sky pale, the city humming below like a hive.
Cael unwrapped his protein bar and watched the daily choreography of Gravitas. At this hour, the streets reached peak density—thousands of Orbiters moving through the city in patterns dictated by gravitational etiquette. The strongest fields commanded the widest berth, lesser Orbiters flowing around them like water around stones. At intersections, traffic controllers—six-orbit specialists with precisely tuned Binding orbits—managed the gravitational interactions to prevent field collisions that could shatter windows or crack pavement.
It was beautiful, in a way. From up here, the individual cruelties of the hierarchy vanished. You couldn't see the Dwarfs being shoulder-checked out of walkways. You couldn't see the Unregistered skulking through alleys, avoiding the scanners mounted at every major intersection. You couldn't see the children in the assessment centers, sitting on metal stools while technicians measured their worth in orbital counts and told them what they would become.
From up here, Gravitas was just a city. And Cael was just a boy eating lunch in the wind.
A patrol cruiser drifted past the tower, its gravitite engines humming at a frequency that made the air shimmer. Inside, enforcers scanned the streets with Sight orbits calibrated for detecting Unregistered activity—unauthorized orbital use, unlicensed gravitational modification, the telltale spikes of black-market Core enhancement. The OA's surveillance network was comprehensive: scanners at intersections, drones in the air, enforcers on the ground, and the tower itself—one enormous sensor array that monitored the city's gravitational baseline and flagged anomalies.
They'd never flagged Cael. His four orbits were so weak they barely registered above ambient noise. He was invisible to the system in the most literal sense—his gravitational signature indistinguishable from background radiation. The assessment technicians had to use targeted, close-range sensors just to detect his orbits at all.
Invisible. That was the word for Dwarfs. Not oppressed—the OA didn't actively oppress them. Not persecuted—there were protections, programs, the veneer of institutional compassion. Just... invisible. Beneath notice. Below the threshold where society decided to care.
Cael finished his protein bar and crumpled the wrapper. Far below, in the plaza, he could see a group of children on a school field trip, led by their teacher to the tower's public entrance. They would tour the lobbies, see the orbital displays, watch a demonstration by a six-orbit enforcer, and leave believing that the Orbital Authority existed to protect them. Half of them would develop functional orbits by adolescence. The other half would learn what the word "Dwarf" meant from the inside.
He wondered which half was luckier.
The wind shifted. For a moment—just a moment—Cael felt the vibration in his chest spike. Not a hum this time. A pulse. Strong, singular, like a fist striking a drum once and stopping. It pushed against his ribs from the inside, and the mop on his cart rattled as if caught in a tremor.
Then it stopped. The mop settled. The wind blew.
Cael pressed his hand to his sternum and felt nothing but his own heartbeat, steady and ordinary. He stared at the mop for a long time, then picked it up and went back inside.
Three more hours. Three more floors. Then home, silence, the photograph, and the dark.
The same.
Always the same.
