The Elder was already dead when Agent Reyes pushed open the cemetery chapel door, but that was not what stopped her cold. It was the smell—copper and ozone, wrong for a body three days in the ground, wrong for the dry summer air of the Burgundy countryside. It was the smell of something that had burned recently and hot.
The chapel was small, medieval, built from limestone that had weathered to the color of old bone. The pews had been removed at some point in the last century, leaving a stone floor scattered with debris and, in the center, an altar that had been stripped of its cloth and candlesticks. On the altar, arranged in a precise geometric pattern, were seven objects that Reyes cataloged without touching: a compass with no needle, a ring made of an unidentifiable metal, a book bound in something that wasn’t leather, a glass sphere containing what appeared to be smoke that moved against no draft, a knife with a blade that seemed to absorb light, a key of impossible length, and a photograph of a woman who had died, according to the case file, in 1923.
“Don’t touch the sigil,” said a voice from the shadows. Dr. Yuen emerged from behind a crumbling pillar, his face gaunt beneath the pale light filtering through the broken windows. He looked like a man who had not slept in weeks. His coat was torn at the shoulder. His hands, Reyes noticed, were shaking. “The Elder designed it to kill anyone who didn’t carry the marker. It’s been active since his death. Three people have tried to enter this chapel. One is in a hospital in Lyon with burns across forty percent of her body. The other two are dead.”
“The marker,” Reyes repeated, her hand drifting to the tattoo on her wrist—the same one they’d found carved into the Elder’s palm during the autopsy. A design that had appeared in no historical record until three weeks ago, when the Elder’s encrypted files had been breached and the first fragments of the Covenant’s history had become readable. “You know what this means.”
“It means the Covenant is collapsing,” Yuen said. “The Elder was the last living founder. With him gone, the encoded sequence dies with him—unless someone reads it before it degrades. The sigil is tied to his neural pattern. His death released a decay cascade. We have perhaps forty-eight hours before the pattern is unrecoverable.”
“And then?”
“And then the information goes with it. The truth about the Celestial event—the one from 1908, the one that everyone agrees happened but no one agrees on what it was—disappears permanently. And so does everything the Covenant learned from it.”
They moved to the body. The Elder lay propped against the base of the altar, his hands folded across his chest with the theatrical precision of a man who had planned his own staging. On his palm, the sigil pulsed faintly—a living wound in his skin, the ink still wet after death, still reactive, still connected to whatever system it had been designed to maintain.
Reyes photographed it. Yuen transcribed the surrounding text—Latin prayers mixed with something older, something that predated the Roman roads by centuries, symbols that seemed to shift when viewed from different angles. They worked in silence for twenty minutes, the only sounds the scratch of Yuen’s pen and the occasional groan of settling stone.
“There’s a chamber beneath the chapel,” Yuen said. His voice had dropped, the way people dropped their voices in the presence of something they feared or revered. “The Elder mentioned it once, when he thought he was dying. He said the truth about the Celestial event wasn’t in any archive. It was buried under St. Petersburg, under the Gobi, under a temple in Angkor Wat. Three locations. Three keys. And this—” he gestured at the sigil, “—this is the lock.”
“And we’re standing in front of the first door.”
“The first door. Yes.”
They found the trapdoor under a loose flagstone at the back of the chapel. It led down into darkness that smelled of mineral earth and something mechanical—gears, ancient and vast, grinding slowly in the deep, maintaining a function that had been running for longer than the chapel above it. The ladder was iron, rusted but solid. The descent took three minutes.
At the bottom, a corridor extended into the rock, lit by phosphorescent compounds that had been maintaining a pale blue glow since before the chapel was built. The walls were carved with the same symbols from the Elder’s palm. At the end of the corridor, a door of black stone stood slightly ajar.
The Elder’s final gift was a map. It was drawn on the inside of the door, visible only when the door was open, a schematic of locations that Reyes recognized from the briefing documents—a network of sites that the Covenant had been investigating for a century. The first step toward understanding what had fallen from the sky in 1908. The first step toward understanding what was about to fall again.
Reyes memorized the map. Then she sealed the chamber, notified her command, and began the process of assembling a team for what would become, depending on how the next forty-eight hours went, either the most important archaeological discovery in human history or the last mistake the Covenant would ever make.
