Quilla fumbled with her phone, thumb hovering over her contacts. She searched for Dad—for Elias Raven—but the screen flickered with violet static. The Leakage was already interfering with the network. Each time she tried to place the call, the signal bars dropped to zero, and the device emitted a low, rhythmic tapping—the same sound she'd heard in the attic.
Her stomach tightened. It wasn't just interference. It was a warning.
"The lines are down, Quilla," Aunt Hel said, her voice tight as she stared at her own useless screen. "The Auditor has put a No‑Fly Zone around this house. You won't reach him by phone. The only way to save him now is to make sure you can survive the trip to the Sump."
Quilla lowered the phone, her hand trembling. "So I can't even call him? I can't even hear his voice?"
Hel shook her head. "Not unless you want the Auditor to answer instead."
She didn't lead Quilla back to bed. Instead, she kicked aside the rug in the drawing room, revealing a heavy iron hatch embedded in the floor. The sound of the metal scraping against the wood echoed like a tolling bell.
"If you're going to the Vaults, you need to learn how to Audit in the Dark," Hel commanded, gesturing toward the ladder that descended into pitch‑blackness. "Silas was a test, and you passed. But the Air‑Traffic Auditor doesn't use illusions. He uses Weight. He will try to crush your soul with the collective grief of every lost suitcase and missed connection in London."
Quilla swallowed hard. The thought of descending into that darkness made her knees weak, but the Signet Ring pulsed faintly against her skin, as if urging her forward.
The basement was lined with rows of charged lead containers, each humming faintly, their surfaces etched with Clarke sigils. The air smelled of incense and iron, sharp enough to sting her nose. Hel tossed Quilla a pair of heavy‑duty Reaper Gloves and a small silver whistle.
"The Vaults are a labyrinth of shifting hallways," Hel explained, lighting a stick of pungent incense that filled the air with acrid smoke. "The Auditor will try to separate your mind from your body. This whistle is a Frequency Anchor. If you feel yourself pixelating, blow it. The sound will pull you back to the physical plane."
Quilla turned the whistle over in her palm. It was cold, heavier than it looked. She imagined herself lost in the Vaults, her body wandering while her mind dissolved into static. The thought made her clutch it tighter.
Hel moved to a locked cage at the far wall. With a practiced motion, she slid the bolt and opened it. Inside, a small, fluttering creature stirred—a Grade‑3 Grief‑Mite. It looked like a tattered boarding pass, its edges frayed, its surface covered in faint, shifting words. As it rose into the air, it whispered in a chorus of voices: apologies, regrets, promises never kept.
Hel released it into the room. "Bind it, Quilla! Use the Ring. Find its debt and settle it before it drains the warmth from your hands!"
The Grief‑Mite circled Quilla's head, its whispers tightening around her like a net. She felt the temperature drop, her breath fogging in the air. The voices pressed against her skull—I should have stayed… I should have called… I should have said goodbye…
Her knees buckled, but she forced herself to stand. The Signet Ring began to glow, faint at first, then brighter, until its light cut through the haze. She raised her hand, focusing on the creature. Through the Ring's circle, the Mite's form shifted. It wasn't just a scrap of paper—it was a ledger entry, a single line of debt.
She saw it clearly: Unspoken farewell, Terminal 3, Gate 27.
Quilla's breath caught. It wasn't her regret—it belonged to someone else, a traveler who had left without saying goodbye. The Mite was feeding on that unfinished moment, clinging to it like a parasite.
"Call it out!" Hel barked. "Name the debt, then settle it!"
Quilla's voice shook, but she forced the words out. "Unspoken farewell, Terminal 3, Gate 27. Reckon!"
The Ring flared. Threads of white static whipped outward, wrapping around the Mite. It shrieked, its whispers rising to a piercing pitch. Quilla felt the warmth return to her fingers as the threads tightened, pulling the creature into the Ring's glow.
Then, silence. The Mite dissolved into ash, leaving only a faint shimmer in the air.
Quilla staggered, her chest heaving. "I… I did it."
Hel nodded, her expression unreadable. "You settled a fragment. A small debt. But the Vaults are full of thousands like that, all clamoring at once. If you can't hold your ground against one, you'll drown in the Sump."
Quilla looked down at the Ring. It was still glowing, faintly humming against her skin. She realized the truth: every settlement was a battle, every debt a weight. And the Air‑Traffic Auditor carried centuries of them.
Hel stepped closer, her voice softer now. "Your mother trained for years before she faced the Vaults. You don't have that luxury. But you have instinct. And instinct is what kept you alive against Silas."
Quilla clenched her fists. "If Dad's down there, if Mom's down there, then I have to go. I can't just sit here while they're trapped."
Hel's eyes narrowed. "Then you'll need more than instinct. You'll need to learn how to carry the Weight without breaking."
She gestured to the rows of lead containers. "Each one holds a fragment of unresolved grief. Tonight, you'll practice binding them, one by one. You'll learn to hear the Ledger's voice without losing your own. And when the time comes, you'll walk into the Vaults not as a frightened girl, but as an Auditor."
Quilla's heart pounded. She thought of her father's laugh, her mother's steady hands, the promise of return that had never been kept. She thought of the tapping in the attic, the whispers in the sludge, the obsidian eyes of Silas.
She raised her hand, the Ring glowing brighter. "Then let's start."
Hel smiled faintly, though her eyes were shadowed with worry. "Good. Because the Auditor is already watching. And he doesn't wait for anyone."
