The air in the mausoleum didn't just vibrate; it shrieked. It was the sound of reality being stretched over a rack.
Eliza's hand was no longer flesh and bone. As she lunged, her arm became a streak of incandescent gold, a living conduit for the Collector's ancient, uncompromising math. She didn't aim for Maryan's throat or her heart. She aimed for the Void—the pulsing, oily rupture in the center of her sister's chest where the Devourer sat like a bloated spider.
"You wanted to be me, Maryan?" Eliza's voice wasn't a scream; it was a tolling bell, resonant and terrifying. "Then feel the weight of every second I spent loving a ghost."
When Eliza's palm slammed into Maryan's sternum, the world went silent.
The violet smoke froze. The shadows stopped flickering. For a heartbeat, there was only the agonizing, white-hot friction of two opposing infinities meeting in a single point of impact.
Then, the Audit began.
It wasn't a physical blow. It was an infusion. Eliza opened the floodgates of her soul. She didn't feed Maryan memories of the summer garden or the stolen peaches—she fed her the Truth of the pain those memories caused.
She poured in the sensation of the arsenic burning her throat in the first life. She poured in the suffocating weight of the pearls she wore just to make Maryan smile. She forced the Devourer to swallow the raw, jagged agony of standing on the Winter stairs and realizing her sister was the one holding the knife.
Maryan's body arched backward, her spine snapping into a terrifying, unnatural curve. Her jaw unhinged further than humanly possible, a torrent of violet ash spewing from her throat.
"Too... much..." the Devourer's voice croaked, no longer a roar, but a wet, drowning gurgle.
"Eat!" Eliza commanded, her eyes burning with such intensity that the stone beneath her feet began to liquefy into glass. "Consume the reality of what you've done! Taste the blood on the ledgers! Feel the cold of the Grey Meridian!"
It was a psychic flaying. Maryan's skin began to crack, glowing gold from the inside out as the "Pure Intent" of Eliza's life collided with the "Infinite Hunger" of the Void.
The pain was a shared circuit. Eliza felt her own nerves being stripped bare. Every memory she forced into Maryan was a piece of herself she might never get back.
She felt her mother's face dissolve.
She felt the sound of her father's laughter turn to static.
She was hollowed herself out to drown the monster in the overflow.
Maryan's eyes began to leak a thick, golden light that sizzled against her bruised cheeks. The obsidian shard in her chest—the anchor of the Devourer—began to glow white-hot, vibrating until it reached a frequency that shattered every urn in the tomb.
"Eliza... stop..." Maryan's real voice surfaced for a split second, a thin, thready gasp of pure terror. "It... burns..."
"It's the Truth, Maryan," Eliza whispered, her face inches from her sister's, their foreheads touching in a macabre parody of affection. "It only burns the things that aren't real."
With a final, agonizing surge, Eliza pushed the last grain of sand—the one representing her own heartbeat—into the center of the violet fire.
The Devourer didn't just die; it detonated.
The explosion was silent. A shockwave of pure, blinding white expanded from the center of the sisters, vaporizing the violet smoke, shattering the Shadow-Echoes, and scouring the darkness from the stone walls.
The silence that followed was absolute.
The mausoleum was stripped bare. The moss was gone. The soot was gone. Even the dust had been bleached white.
Eliza slumped to the floor, her breath coming in ragged, wet gasps. Her left arm was charred, the skin etched with silver lines that looked like lightning strikes—the Hourglass Scars.
Her wrist was blank.
No sand.
No ticking.
Only a dull, aching silence.
Ten feet away, Maryan lay in a heap of shredded emerald silk. She wasn't a monster anymore. She was just a girl. Her skin was pale, her hair tangled with ash, and her eyes were open, staring at the ceiling with a vacant, shattered expression. The Devourer was gone, leaving behind a soul that looked like a burnt-out forest.
Eliza crawled toward her, her movements slow and agonizing. She reached out a trembling hand and touched Maryan's cheek.
Maryan blinked. A single tear, clear and human, tracked through the soot on her face.
"I... I can't feel the hunger," Maryan whispered, her voice barely audible. "But Eliza... I can't feel anything else, either."
Eliza pulled her sister's head into her lap, mirroring the way she had held Silas. She looked toward the door, where Silas was beginning to stir in the rubble, his eyes searching for a reason to stand up.
"The debt is settled, Maryan," Eliza said, her voice a broken thread of gold. "The Audit is over. We're finally just... us."
But as Eliza looked at her own transparent hands, she realized the price of the Reverse Audit. She had won the war, but she had spent every second she owned to do it.
The Grey Meridian was calling. And this time, she didn't have any sand left to bargain with.
