The air in the carriage was thick enough to choke on.

Iseon sat across from me, his gaze fixed on the passing city lights. His blue eyes, those unnatural marks of his vow-bound objectivity, were cold. He wasn’t looking at a wife. He was looking at a puzzle box he couldn’t decide whether to solve or smash.

“The audit confirms Count Namgung died on the fourteenth,” I said, breaking the silence. “The entry for the crime against House Han is dated the sixteenth. His signature is right there, at the bottom of the scroll.”

“A clerical error is more likely than a conspiracy, Seorin,” Iseon replied. His voice was a flat line. “One forged signature does not dissolve the other two crimes. Nor does it explain the Blood-Debt tied to my soul.”

“It’s a thread,” I whispered. “Pull one, and the whole tapestry unravels.”

We arrived at the Eastern District Shrine, a quiet place where the local registry was kept. This was where the life and death of every noble was recorded before being sent to the High Archive. If the Archive was the ocean, this was the stream that fed it.

Inside, the smell of incense and old paper greeted us. An elderly priest bowed low, his hands trembling as he realized the Crown Prince was standing in his sanctum.

“The ledger for the month of the Harvest,” I commanded. “Specifically, the death certificates and the ritual attendance logs.”

It took twenty minutes for the priest to find the volume. I felt the pressure of the deadline in my marrow. Two days left. If I didn’t find the proof here, the 24-hour stay of execution would expire, and I’d be right back on the block.

I flipped through the pages. There it was: *Count Namgung. Cause of death: Heart failure. Date: 14th of the Month.*

“Look at this,” I said, beckoning Iseon closer.

He leaned in, his shoulder brushing mine. For a second, he stiffened, but he didn't pull away. I pointed to the signature next to the death record. Then, I flipped the page to the Attendance Log for the 15th—the day after the Count died.

*Witnessed: Vow of Intent. Attendant: Count Namgung.*

“The ink,” I whispered.

I ran my fingers just above the paper. In this world, mana-dipped quills left a faint resonance. To the naked eye, the signatures looked identical. But I saw it—the way the ink on the 15th sat *on top* of the paper’s grain, while the older entries were absorbed deep into the fibers.

“It’s fresh,” I said. “This wasn’t written a month ago. It was written yesterday.”

Iseon’s eyes narrowed. He reached out, his gloved hand hovering over the name. “That’s impossible. These ledgers are sealed with a minor ward. Only a priest or a high official can break the seal to add an entry.”

“Unless the seal itself is a lie,” I countered.

I looked at the priest, who was pale. “Father, did you see Count Namgung here yesterday? Think carefully. He has been dead for weeks.”

The priest swallowed hard, his eyes darting. “I… I remember the ceremony. There were candles. A vow was being witnessed. He was there. I saw him with my own eyes.”

My heart sank. “You saw a dead man?”

“He spoke!” the priest insisted. “He signed the book and left. He wore the Namgung crest. It was… it was a vow ceremony. Everyone remembers it.”

I looked at Iseon. This was the memory instability the Archive Master had hinted at. If a record is forced into the Ledger, the world—the people in it—adjusts to accommodate the lie. Reality was rewriting itself around a forgery.

“They didn't just forge a signature,” I realized aloud. “They staged a ghost. They’re using the Archive to manufacture memories.”

I pulled a small, sharp pin from my sleeve and carefully pricked the corner of the page.

“What are you doing?” Iseon asked, his voice sharp.

“If this is a recent alteration, the resonance won’t be stable yet.”

I pressed a drop of my blood—the blood of a House Yoon daughter, bound now to the Imperial line—onto the fragment of the page.

As the blood hit the paper, the ink didn't smear. It *shivered*.

Small, glowing script began to crawl out from beneath the visible signature. It wasn't a name. It was a string of command code, written in a dialect of the old tongue I shouldn't have been able to read, yet my copywriter’s brain recognized the pattern instantly.

It was a ‘Replace’ command.

*Target: Memory of Witness. Source: Shadow of the Throne.*

Iseon grabbed my wrist, his grip like iron. His eyes were no longer cold—they were burning with a terrifying, blue fire.

“Where did you learn to trigger a hidden sigil?” he demanded. “That is a high-level Archive technique. No copywriter—no *vile daughter*—should know how to peel back the skin of a record.”

I looked him in the eye, my pulse thrumming against his palm. “I didn’t learn it, Iseon. I’m just proofreading the world. And right now? The world has a massive typo.”

The fragment of paper in my hand suddenly turned black, the glow intensifying until it began to burn.
