The problem with packing near-infinite cosmic mass into your gut, as Austin noted in the margin of his daily inspection log with his carpenter's pencil, was that light stopped traveling in polite, predictable straight lines.
Under normal municipal engineering conditions, light was an honest, well-behaved contractor. It bounced off a surveyor's prism at the angle of incidence, passed through optical transit lenses with a known refractive index, and traveled in a Euclidean straight line from your flashlight to whatever rusted pipe flange you were trying to inspect.
When your localized personal body mass breached five times ten to the twenty-third kilograms, however, Einstein’s general theory of relativity stopped being an interesting chapter in a college physics textbook and became an active, irritating workplace hazard.
Austin was standing on the elevated maintenance gantry of the Vesta Primary Rail Terminal, forty feet above the dusty basaltic floor of the Rheasilvia crater. In his left hand, he held a heavy-duty twelve-volt LED work light with an impact-resistant rubber housing, and in his right, he held a calibrated set of dial gauges, checking the wheel flange wear on Bogie Four of an automated sixty-car iron ore train. The airless sky above Vesta was pitch-black, sprinkled with millions of sharp, unwinking diamond stars and the distant, glowing golden ring of the Earth-Moon system millions of miles away.
Austin flicked the rocker switch on his work light, aiming the beam downward to inspect the hardened steel journal box on the train's front axle.
The light beam did not illuminate the journal box.
Instead, the cone of bright white photons bent sharply at a ninety-degree angle eighteen inches from Austin’s stomach, entered a tight circular trajectory, wrapped around his lower spine, whipped past his right hip holster, and shot straight back into his eyes with blinding intensity.
"Ow," Austin grunted, squeezing his eyes shut behind his sunglasses and snapping the work light off with a quick flick of his thumb. "What in the world was that? Did someone mount a curved chrome mirror to my tool belt?"
He opened one eye cautiously. There was no chrome mirror.
Around his waist, his localized accretion ring—the tin lunchbox, utility knife, brass sharpener, crescent wrench, reciprocating saw, spirit level, and linesman’s pliers—was still orbiting peacefully at twelve feet per second. But now, nestled between the wrench and the spirit level, was a paper-thin, shimmering ring of pure, trapped golden luminescence: a continuous, circular track of photons caught in a closed, circular null geodesic around his waist.
Every stray photon of light from the binary suns, the distant stars, and the welding torches across the crater that passed within twenty inches of his navel was being captured by his gravitational field, bent into a circular loop, and forced to orbit his torso at the speed of light.
Before Austin could pull out his measuring tape, his dantian resonated with a deep, bone-rattling pulse that caused the entire forty-foot steel rail gantry to groan in structural sympathy.
A brilliant, deep-violet system notification flared in his heads-up display, accompanied by the low, resonant chime of a heavy brass ship's bell:
Austin stared at the blinking system box, his teeth gritted as eighty-five times Earth gravity pressed down upon his collarbones like a solid slab of wet granite.
"Six point seven lunar masses," Austin muttered through clenched teeth, his boots sinking a quarter of an inch into the steel diamond plate beneath him. "And my fluid dampers are hunting between twelve hundred and twelve fifty RPM."
He keyed his radio.
"Tie Kuang! Bring up the reserve ballast cart! I need two additional twenty-five-pound lead slugs to bring the frame up to twelve hundred and fifty pounds! And bump the fluid damper circulation pressure to ninety PSI!"
Across the rail yard, Tie Kuang dropped his torque wrench with a loud clatter. The burly blacksmith scrambled across the gravel, hauled two stamped yellow lead ingots from the mobile safe, and hurried up the gantry stairs, followed closely by Southern Sword Saint Jiang Taixu.
Down on Track Bravo, former Sovereign Chen Tian and Elder Mo Fan paused their sweeping, looking up at the elevated gantry with jaws slack.
"By the Sovereign of the Deep Void..." Chen Tian whispered, his push broom slipping from his trembling fingers. "Look at the Lord Architect's waist! The Photon Sphere... the legendary Crown of the Void's Edge! For sixty million years, our Citadel's greatest astronomers only saw that phenomenon around the ancient supermassive black holes at the galactic core! How can a mortal cultivate a photon sphere within his flesh?!"
"He... he does not merely possess a golden core, Sovereign," Mo Fan whimpered, clutching his chest. "He is an astronomical black hole walking on two legs!"
As Tie Kuang stepped within six feet of Austin on the gantry, the eighty-five-G gravitational gradient seized his boots, forcing the blacksmith down onto one knee with a heavy *CLANG* against the steel riser.
"Austin!" Tie Kuang wheezed, his eyes bulging as he looked at Austin’s waist. "Look at your midsection! The... the Halo of Pure Light! It is spinning around your waist like a celestial hula hoop!"
Jiang Taixu had fallen completely flat upon his chest on the diamond-plate deck, his chin resting against the metal, his ancient eyes filled with overwhelming, tearful veneration.
"The... the Golden Wheel of the Unconquered Sovereign..." Jiang Taixu wept into his comms. "The ancient sacred scrolls of the Heaven-Cleaving Sect spoke of this... When the Lord of Creation reaches the Eighth Gate of the Deep Void, the divine light of the stars refuses to depart from his presence! The photons themselves prostrate before his waist, unable to escape his boundless karmic pull!"
The ancient sword saint raised trembling hands, attempting to hold up a small quartz prism to refract the halo. "If I can capture but a single beam of this light, I can forge seven celestial rainbow swords—"
"Put that prism away before you blind yourself, Taixu," Austin snapped, reaching down with one gloved hand to take the first twenty-five-pound lead slug from Tie Kuang’s tongs. "It’s a photon sphere. When a compact mass becomes sufficiently dense, the escape velocity at one point five times the Schwarzschild radius equals the speed of light. Any photon traveling tangentially at that specific radial distance gets trapped in an unstable circular orbit. It’s basic general relativity. And right now, it’s a massive OSHA eye-hazard."
*CLANK.*
Austin slid the first lead slug into his left hip holster.
He reached down to his thigh console, slapping the override lever on his hex-chamber hydrodynamic fluid dampers. The high-pressure synthetic fluorocarbon surged through the six counter-rotating balancing tubes wrapped around his hips. The high-speed gyroscopic pumps whined like miniature jet turbines as their rotational speed climbed from twelve hundred to twelve hundred and fifty RPM.
*CLANK.*
The second lead slug locked into his right hip holster with a solid, heavy thud.
The violent eighty-five-G shudder in Austin’s lower back immediately smoothed out into steady, monolithic equilibrium. The twelve hundred and fifty pounds of certified lead ballast counterbalanced the rotational torque of his five-kilometer neutron core with mathematical precision.
Austin let out a long, ragged exhale, rolling his shoulders and testing his footing against the gantry.
"Much better," Austin said, inspecting his clipboard.
Then, he blinked in severe annoyance.
Because the photon sphere was permanently orbiting his waist, every time Austin looked down at his clipboard, the bright ring of trapped sunlight reflecting off his shiny brass belt buckle flashed directly upward into his eyes, obscuring his line numbers and creating blinding green after-images in his retinas.
"Look at this glare," Austin grumbled, holding his hand over his stomach to block the light. "I can’t even read the serial number on Bogie Four's axle bearing. It’s like someone mounted high-beam stadium lights to my belt."
He reached into his leather tool pouch, pulled out a fresh roll of heavy-duty black vinyl electrical tape, and bit off an eight-inch strip with his teeth.
*Rrrrip.*
With a quick, practiced motion, Austin slapped the black electrical tape directly over his shiny brass belt buckle, rubbing it down firmly with his thumb until the brass was completely covered by matte-black vinyl.
*Snap.*
Deprived of the reflective brass surface to scatter from, the trapped photon ring dimmed down into a thin, harmless amber line that circled his hips like a faint neon wire, safely below the twenty-five-lumen glare threshold.
"There," Austin said with satisfaction, dusting off his gloves. "Non-reflective matte finish. Problem solved."
Jiang Taixu and Tie Kuang stared in absolute, stunned silence.
"You... you sealed the Holy Halo of Creation... with black electrical tape?" Jiang Taixu whispered, his voice trembling with sheer, uncomprehending shock.
"It’s matte black vinyl, Taixu," Austin said, picking up his measuring gauges and returning to the train's axle bearing. "It prevents specular reflection and protects your eyes from arc-flash fatigue. Now get off the floor, wipe the dust off your knee pads, and help me check the wheel flange clearances. We have four more trainsets to certify before the morning freight run."
Jiang Taixu slowly pushed himself up from the deck, looking at the black tape covering Austin's belt with an expression of profound, unshakable religious awe.
"The Black Seal of the Sovereign..." Jiang Taixu murmured to himself, writing it down in his logbook. "Even the blinding light of the stars must yield to the Lord Architect's black tape."
Out in the silent blackness of the Asteroid Belt, the automated ore trains began to roll, their heavy wheels clicking steadily across the rails under the soft, serene glow of a man who had bound the light of heaven to his tool belt.
