Chapter 2
The snap of the rock was louder than thunder in his own skull.
Riven didn’t think. He didn’t calculate the structural integrity of the precipice or weigh the geological odds of a localized collapse. Instinct, honed by two decades of being the weakest thing in a fortress of monsters, took over completely.
He threw himself backward.
His iron-toed boots scrambled uselessly for a fraction of a second against the slick, calcified ash before he found purchase.
He launched his body away from the yawning abyss, his elbows slamming violently into the uneven, freezing ground.
He scrambled backward on his hands and crabs, kicking up plumes of pale grey dust, his breath tearing in and out of his lungs in ragged, terrified gasps.
He didn't stop until his spine slammed hard against the base of a towering obsidian spire, knocking the remaining wind from his chest.
Riven sat there in the dark, his knees pulled tight to his chest, his calloused hands gripping his hair.
He squeezed his eyes shut and waited for the deafening roar of falling rock.
He waited for the floor to drop away. He waited to join his parents in the crushing, suffocating black of a dungeon cave-in.
But the roar never came.
There was only the heavy, oppressive silence of the Ashen Reach, broken by the frantic, rapid-fire hammering of his own heart.
Slowly, agonizingly, Riven opened his eyes. He lowered his trembling hands from his head and peered through the jagged strands of his ash-grey hair.
The precipice was still there. The ledge had not collapsed into the endless dark. But three feet from the edge, exactly where his knees had been pressing into the stone, a jagged, jagged fault line had opened in the basalt.
It was bleeding light.
It wasn't the erratic, blinding blue glare of the subterranean moss. It was a deep, rich, terrifyingly warm gold. It pulsed softly, casting long, wavering shadows across the pale ash. It looked like molten metal trapped just beneath a thin layer of ice, waiting to break through.
Riven swallowed hard. His throat felt like it was coated in ground glass.
An elemental leak, he told himself. His internal voice was frantic, desperate to build a logical cage around the impossible. It’s an elemental leak. A cracked fire-core from some Delver-Knight's faulty weapon. Or a proximity mine left behind by the faculty.
Magic was lethal to the Unattuned. It was a well-known, brutal fact of Spireheart Academy.
Unattuned bodies lacked the arcane circuitry to process raw aether.
Being too close to an unshielded elemental core could boil a servant's blood or turn their nervous system to actual ash.
The golden light spilling from the crack wasn't a miracle; it was a death sentence.
He needed to get away from it. He needed to get back to the service lift, pull the rusted lever, and ascend back to his sunless, damp bunk in the lower dormitories. Dravon’s threat echoed in the vast cavern, bouncing off the jagged rocks. Go down to the Ashen Reach. Scrub it.
If he returned to the Atrium with a dry rag and an unscrubbed floor, the noble would snap his neck. If he stayed near the glowing crack, the residual magic might cook him alive from the inside out.
Riven let out a pathetic, stifled groan, pressing the heels of his hands against his eyes. He was trapped. He was always trapped.
"Just finish the job," he whispered to the empty cavern. His voice trembled so badly it sounded like he was freezing to death. "Just clean the stain. Be a ghost. Go back upstairs."
He lowered his hands. He looked at the acidic, dark stain left by the Gloom-Hound near the edge of the abyss. It was an ugly, viscous smear that smelled of rotting meat and battery acid. To clean it, he needed water. His bucket was entirely empty, ruined by Dravon’s cruelty in the Atrium above.
Riven’s gaze darted around the oppressive dark of the upper Stratum. His eyes locked onto the patches of bioluminescent moss clinging to the side of the obsidian spire to his left.
Down in the lower dorms, the sweeps knew that the blue moss was heavily saturated with moisture.
It fed on the ambient humidity of the dungeon.
Sometimes, when the academy turned off the water to the servant quarters as a punishment, the maintenance caste would scrape the moss from the walls and press it through thick canvas to extract a few drops of bitter, chalky water.
Riven pushed himself off the ground. His legs felt like lead. The caustic lye-water that had soaked his shins earlier was beginning to severely blister his skin beneath the heavy canvas overalls, adding a constant, stinging heat to his misery.
He limped toward the massive patch of glowing blue flora.
As he drew closer, stepping out of the shadows and into the harsh, azure glare, the sharp pain in the back of his skull returned.
It was a deep, throbbing ache directly behind his eyes.
He blinked rapidly, trying to clear his vision.
The cavern seemed to shift, coming into an unnatural, terrifyingly sharp focus.
He reached out to rip a handful of the moss from the black rock.
His hand froze in mid-air.
Riven stopped breathing. He stared at the glowing patch of vegetation. His fractured, amber-tinted eyes widened in sheer, unadulterated horror.
It wasn't growing. Not like a plant should.
In his twenty years of life, Riven had seen weeds push through the cracked paving stones of the academy courtyards.
He had seen the twisting, chaotic roots of the silverwood trees.
Nature was messy. Nature was random. It sought the path of least resistance, sprawling and curving wherever it pleased.
The moss on the obsidian spire was not random.
It was expanding in perfect, rigid lines.
It grew straight up for exactly three inches, made a sharp, flawless ninety-degree turn to the right, continued for six inches, and then branched off in perfect right angles.
It formed a grid. A massive, complex, mathematical grid of glowing blue circuitry laid perfectly flat against the uneven rock.
Riven stared at a specific cluster. He watched as the bioluminescence pulsed.
Thrum.
The light traveled down a straight line, hit a right angle, and split into two perfectly symmetrical geometric squares.
Thrum.
It wasn't a fungus. It wasn't a weed. It was an arcane schematic. It was a map of the stone itself, disguised as biology.
"No," Riven breathed. He took a slow step backward. "No, no, no."
This was high magic. This was the deep lore of the First Builders, the forbidden geometry that the High Proctors of Spireheart hoarded in their highest towers.
It was the stuff of executions and torture.
An Unattuned sweep looking at the raw code of the Crucible was a crime that would see his eyes burned from his skull with hot irons.
He tried to look away. He commanded his neck muscles to turn his head. But the throbbing ache behind his eyes flared into a blinding spike of agony.
The stone called to him.
It wasn't a voice. It was a physical pull, a magnetic drag on the iron in his blood. Without his permission, his trembling right hand drifted toward the flat basalt wall beneath the pulsing geometric grid of moss.
His calloused fingertips hovered exactly one inch above the freezing rock.
The low, grinding frequency of the dungeon—the background noise he had lived with his entire life—suddenly vanished. The cavern fell into a dead, terrifying silence.
Then, the rock vibrated.
Ba-thump.
Riven gasped, his chest heaving.
The vibration wasn't the slow, tectonic shifting of the mountain. It was rapid. It was frantic.
Ba-thump. Ba-thump. Ba-thump.
Riven stared at his own chest. He felt the terrifying, rapid-fire hammering of his terrified heart against his ribs. He looked back at his hand hovering over the stone.
The basalt was perfectly mirroring his heartbeat.
The entire cavern, the millions of tons of crushed rock and obsidian and calcified ash, was actively synchronizing its frequency to the pathetic, racing pulse of an Unattuned maintenance sweep.
Heat radiated from the stone. It wasn't the scorching, ozone-scented heat of Dravon’s runic armor.
It was a deep, ancient warmth. It felt like standing near a massive hearth on a freezing winter night.
It felt welcoming. It felt like it was waiting for him to simply press his palm flat against the geometry and take control.
"Stop it," Riven whispered, his voice cracking into a panicked sob.
He didn't want control. Control meant responsibility. Control meant the High Proctors would hunt him down and dissect him on a marble slab to understand how a rat had hijacked their sacred labyrinth.
He ripped his hand away.
The physical connection broke with the sharp crack of static electricity. Riven stumbled backward, tripping over his own heavy boots, and fell hard onto his backside in the ash.
The low, grinding tectonic hum of the dungeon immediately returned, rushing back into his ears like water breaking through a dam. The geometric grid of moss continued its silent, pulsing path, indifferent to his terror.
Riven lay on his back, staring up into the yawning black nothingness where a ceiling should be. His chest heaved. He was covered in a cold sweat that instantly turned to ice in the subterranean draft.
You are a sweep, he told himself. He repeated it like a mantra, a shield against the impossible reality pressing in on him. You are Riven Cale. You hold a broom. You do not look at magic. You do not touch the stone. You clean the floor and you survive.
He rolled over onto his hands and knees. He refused to look at the moss again. He refused to acknowledge the perfect right angles.
He crawled across the ash, dragging his ruined rag with him. He scrambled back toward the edge of the precipice, keeping his head down, his chin tucked tight against his chest. He stopped right beside the dark, acidic smear of Gloom-Hound drool.
