Chapter 1: 断角来函

Sea fog clung to the coastal docks of Takna like a gray cloth soaked in ice water, draped tightly over the city’s edge. Mateo Qispe stared at the ink lines in his hands, his fingertips trembling from long tension. That tremor introduced a disturbing deviation into the otherwise straight warp and weft of his grid. As the municipal office’s most rigorous cartographer, such a mistake was almost unforgivable. He took a deep breath, trying to suppress the churning in his stomach triggered by the damp air. The mournful cries of seabirds outside penetrated the glass, carrying the briny scent of salt into his nostrils. In that moment, a rapid yet stifled footstep shattered the dead silence of the surveying room, breaking his concentration.

A hunched courier stood in the doorway, his face devoid of expression, looking like nothing more than a mummy eroded by sea winds. In his hands, he cradled a rust-spotted iron box, wrapped in several coils of cable that had long since dried and turned black. Mateo frowned, instinctively stepping back half a pace. His pencil hovered in the air. In a city saturated with conspiracy and transaction, items of unknown origin often signaled the start of danger. He refused to allow any personal contraband to defile his pride-of-own-workspace.

"This is the last relic from your father’s old estate," the courier said, his voice raspy, like sandpaper grinding against slate, utterly flat. "Before he died, he specifically instructed that no matter what, it must be delivered to the City Hall. This is the only copy."

Mateo’s icy gaze swept over the layer of rust, a fire of unbidden resentment burning within him. His father had been dead for years. That home, filled with lies and betrayal, was one he had sworn never to set foot in again. Now, a rat crawling out of the gutter attempted to blackmail the living with the shadow of the dead. He shook his head, his eyes carrying a chill that kept the world at arm’s length.

"I don’t accept this," Mateo said, his tone steady but laced with undeniable finality. "We only process public navigational data here. We do not accept private donations. Take that trash out. Do not dirty the carpet."

"Time is short, Mr. Qispe." The courier did not retreat. A strange urgency flickered in his murky eyes, like a predator sensing the smell of blood. "If I don’t hand this to you personally, it will sink to the bottom of the sea. You will regret it. Just as your father regretted it in the past."

Mateo ignored the veiled threat. He turned back to proofing the complex tidal markers, trying to shield the turmoil within by leaning on the monotony of his work. Yet, the iron box was not taken away. Just as his hand touched the edge of the chart, a gust of wind carrying moisture slammed into him. The iron box crashed into his embrace with a force that defied physical sense, cold and hard, embedding itself in the gaps of his ribs as if it possessed life. He snapped his head around. The doorway was empty. Only the cable that had once been tied to the iron box remained, winding away into the thick fog like a snake.

Mateo clutched the iron box tightly, his knuckles turning white from the grip. It was then that he noticed a subtle family crest carved onto the lock on the side of the box—a vulture with outstretched wings. It was the Qispe family’s abandoned totem, symbolizing the dignity of the cartographer. This detail pierced through his carefully constructed defenses of indifference like a red-hot needle, making his firm refusal waver.

Back in his office, Mateo locked all the doors and placed the iron box on the central desk. He retrieved a precision pry bar and carefully pried at the rusted lock. With a light *click*, the box opened. Inside there was no gold, no jewels. There were only two items: a handwritten letter with yellowed edges, and a fragment of an ancient map wrapped in thick oilcloth. His fingers hovered above them for a long time, refusing to descend. The smell of mold in the air mixed with the sharp, acidic scent of old paper—it was the smell of time rotting away.

He picked up the letter first. The paper was brittle, the handwriting on it scribbled and frantic. At some point, the ink had been soaked by water, forming a blurred, smudged stain. Mateo’s heartbeat accelerated. He recognized the script. It was the characteristic of his father in his final years, trembling and filled with anxiety. He forced down the surging emotions, his eyes sweeping over the broken sentences, attempting to piece together fragments of the truth.

"Mateo, my son." The opening of the letter was brief and heavy, then the tone shifted, revealing a secret buried for years. "The world laughs at Qispe as a thief, saying I stole the inspiration from Rodrigo. But I must tell you the truth is not so. Those foxes at the Merchant Guild stole my life’s work and pinned the crime onto me."

Mateo felt a wave of dizziness, as if a boulder had crushed his chest. For years, he had lived under the stigma of his father’s plagiarism, watching the genius cartographer Rodrigo Almagro stand on the podium receiving public acclaim, while he himself could only endure the mockery in the corner. He had believed his father had accepted defeat until death, that it was a weak default acceptance. But now, this letter cut like a sharp knife, slicing open his rigid understanding of the past and exposing the raw, red flesh beneath.

"That chart was not mine. It was theirs." The final lines of the letter pressed into the paper with force, as if roaring silently. "The navigational route of the Storm Strait is ancient data they excavated from Incan ruins. Rodrigo was merely a puppet. I command you to find that missing corner. That is the key to their hidden crime."

Matteo set the letter down, his fingers trembling slightly. His gaze drifted to the oiled cloth-wrapped bundle beside him, a desire too profound to articulate rising in his chest. With meticulous care, he unwound the fabric, revealing an ancient parchment map to the dim light. It was the renowned "Storm Channel" chart, drawn in the early days of the Age of Exploration, yet it bore the clear marks of later repairs and additions. His eyes swept across the surface, finally locking onto the southeastern corner—a crucial section was missing, its edge a ragged, irregular tear.

"That's impossible," Matteo murmured, his voice echoing in the vacant office. As a cartographer, he knew every edition of every ancient chart by heart. This was a public archive copy, but the missing corner meant that there were no coordinates guiding the route through the channel's most treacherous undercurrents. It was not merely a geographical void, but a logical paradox: why would a map designed to guide ships deliberately leave such a fatal blind spot?

He leaned closer to the jagged edge, retrieving a high-magnification lens from a drawer. Light focused through the glass onto the rough surface, revealing details invisible to the naked eye. The damage was not a natural tear; instead, it featured extremely fine, regular incisions. These marks were not decorative, nor were they stray printing dots. They formed a peculiar arrangement, reminiscent of celestial constellations, yet eerily aligned with symbols of tidal cycles.

Matteo held his breath, his gaze sharpening. He realized these incisions were a code. His father had not died in silence; he had left a cipher on the map's edge. This implied that the missing fragment had not truly been lost, but hidden somewhere only this code could reveal. Behind the map lay a secret far greater than plagiarism—a conspiracy of such magnitude it could shake the very foundations of the surveying world.

The office door creaked open softly. Mercedes K伊斯佩 entered, her sixty-year-old face appearing exceptionally gentle in the dim light, though a deep worry lingered in her eyes. She watched her son clutch the map, his expression distorted as if enduring a silent storm.

"Matteo, you don't look well." Her mother's voice was mild but carried an undeniable piercing power. "What have you found? Is it that 'Ghost Route' mentioned in the diary?"

Matteo slowly raised his head, his eyes meeting his mother's. After a moment's hesitation, he unrolled the map fragment and pointed to the minute incisions. Mercedes' gaze fell on the chart, and a complex emotion flickered in her previously calm eyes—a blend of pain, pride, and hope.

"Yes, this is the truth your father struggled to find on his deathbed," Mercedes said softly, her fingers tracing the marks along the edge. "He kept saying it held his final innocence. Have you finally understood?"

Matteo did not speak, but the firmness in his gaze answered his mother's question. Just then, urgent footsteps echoed outside. Catalina Galvan burst into the room, her expression tense to the point of panic.

"There's no time." Catalina was breathless, her uniform buttons seemingly fastened in the wrong places, making her look disheveled. "Francisco Mendoza's men are at the archive pulling the borrowing records from that year. He has closed the case on this. If this map is made public today, the Chamber of Commerce will pull strings to ensure your father carries the stigma of being a thief forever."

Matteo gripped the map tightly, his knuckles turning white. He looked out the window; the sea fog remained thick, seemingly intent on swallowing the entire city. He understood now: this map with its missing corner was not just a geographical gap, but the only key to clearing his father's name and exposing the Chamber's conspiracy.

"I will find it." Matteo's voice was low and firm, like an iron anchor driven into the abyss. "Wherever that corner is hidden, I will retrieve it."
