Throne of Sin

The temple had been waiting longer than she had been alive. Mariana Cortés pressed her knee into the damp earth. The ache had settled into her lower back sometime around hour four, but she ignored it. Her headlamp cut a narrow cone through the dying light, catching the edge of a carved frieze that had not seen direct sun in six centuries. The air inside the chamber was thick with the smell of wet stone and something floral she could not name—something that had rotted and bloomed in the same breath. Sweat trailed down her spine, soaking the waistband of her cargo pants. She had long since stopped wiping the grit from her palms onto her thighs. The field notebook in her left hand was damp at the corners, its pages beginning to curl. She had been writing in shorthand for so long that her fingers had cramped into a claw around the pen. She did not believe in lost cities. She believed in evidence. The temple had not been on any survey map. That was the first thing that had bothered her. The second was the stonework. The blocks were fitted without mortar, each seam so tight that a knife blade would not have found purchase. The carvings along the lower register showed a style she could not place in any known pre-Columbian tradition. Jaguars, yes. Serpents, yes. But the proportions were wrong. The figures were too elongated; the headdresses too elaborate. The astronomical markers carved into the lintel above the central chamber did not match any constellation she had ever studied. She had spent the afternoon photographing them, measuring them, pressing tracing paper against the grooves. Charcoal had stained her fingers black. None of it made sense. And that was before she saw the stone. It sat on a crumbling altar at the center of the circular chamber. It was glowing. Mariana stopped at the threshold. Her headlamp flickered once—a stutter of light that she blamed on the battery. She reached up to tap the casing. The beam steadied. The stone did not. It pulsed with a light that was not, strictly speaking, coming from anywhere. Not reflected. Not ambient. The jade itself was the color of deep water, a green so dark it was nearly black. Carved across its surface were symbols that shifted as she watched them. She had seen jade before. She had held jade before. She had never seen jade do this. "Okay," she said aloud. Her voice sounded small in the chamber. "That's new." She did not approach it the way a believer would have. She approached it the way she approached everything: with measured, skeptical curiosity. This was the kind that had carried her through three field seasons in the Yucatán; a dissertation on ritual deposition that her advisor had called too cautious, and she had called thorough. She was an archaeologist. She was not a mystic. She was not a treasure hunter. She was a woman who believed in stratigraphy and carbon dating. She believed in the slow, painstaking work of pulling truth from the dirt. The stone on the altar was, at minimum, an anomaly that required documentation. She took a step. Then another. The vines that had swallowed the walls brushed against her shoulders. She pushed them aside without looking. Her boots left prints in the dust that had accumulated on the floor—a fine gray silt that rose in small clouds with each footfall. The chamber was circular, perhaps four meters across. The ceiling had partially collapsed, letting in a sliver of sky that was already deepening toward dusk. Through the gap, she could see the first stars beginning to prick through the canopy. She did not look at them long. Her attention was on the stone. She reached the altar. The jade was cool to the air around it, cooler than the ambient temperature of the chamber. She could feel the chill radiating from its surface before her fingers made contact. She crouched, setting her notebook on the altar's edge. The symbols on the stone were not static. They moved like something alive, like a language that was still being written. She could not read a single character. Not Olmec. Not Maya. Not anything that belonged to a script system she had ever seen catalogued. She pulled her pen from her pocket and sketched a rough approximation of one of the glyphs in the margin of her notebook. But even as she drew it, the shape shifted. The line she had just made no longer matched the mark on the stone. "That's not possible," she said. She said it the way she had said it when the first carbon date had come back from the temple's foundation stones and placed them three hundred years earlier than any known settlement in the region. She said it the way she had said it when the ground-penetrating radar had shown a void beneath the altar that should not have been there. She said it as a statement of fact, not as a prayer. And then she reached out and touched the stone. Her fingers brushed the surface to test its temperature. That was all. She wanted to know if the jade was cold to the touch or if the chill was an illusion of the light. She wanted a data point. She wanted something she could write down. The world tore apart.
