Something tightened low in his gut.
He couldn’t point to anything else. No forced entry. No missing equipment. Just a quiet, electric hum along his spine—the instinct that had kept him alive through three tours and a dozen situations that should have killed him.
Something was wrong.
He shook his head and turned away. He needed eyes on the cave.
The cave entrance sat part way up the northern cliff face, accessible by a narrow path that switch-backed through rock and scrub brush. Zach found it during his initial survey of the island two months ago. Natural formation, approximately fifteen feet wide at the opening, depth unknown. His team had mapped it, cataloged it, added it to the security database as a potential vulnerability.
Noted it had once been used, with symbols carved into the walls.
Today, it felt different.
Zach paused at the entrance. Let his eyes adjust to the dimness.
Cool air wafted out from the depths. The temperature dropped ten degrees at the threshold. Sound changed, too—the ocean breeze faded to a whisper, replaced by the hollow echo of water dripping somewhere deeper inside.
He entered, boots scraping against stone, the noise bouncing back at him from multiple directions. The cave opened into a small chamber about twelve feet in, high enough to stand upright, wide enough for three people side by side. Natural stone, worn smooth by centuries of wind and tide.
Zach swept his flashlight across the walls. No graffiti. No trash. No sign of recent human presence.
There were definite signs of ancient human presence, however.
The beam revealed shallow cuts in the rock—long, deliberate grooves. At first glance, they appeared random: scratches left by erosion or tools dragged across the surface.
He stepped closer.
Not random. Symbols. Lines intersected in repeating patterns: spirals, branching shapes, marks curved like wind-blown leaves. Some were deeply etched, others faded with time, the edges softened by years of salt air and shifting moisture.
Not decorative. Intentional. Carved a long time ago.
Zach ran the light along one section of the wall. The markings continued for several feet, arranged in rows that almost read like writing—except the shapes meant nothing to him. No letters. No numbers. No language he recognized.
Old. Older than the fishing village. Maybe older than anything still standing on the island.
He aimed the beam higher. More carvings emerged, layered over one another as if different hands had returned here again and again over generations.
A meeting place, perhaps. Or a marker. Either way, no one had been here recently. Dust lay undisturbed in the grooves. No boot prints in the sand. No wax drips from ancient candles. Just stone, salt, and silence.
But the air felt wrong. Not structurally. Not physically. Just... off.
He moved deeper. The chamber narrowed into a passage and curved left, then right, before opening into another chamber, slightly larger, but more enclosed. The ceiling sloped down, barely above his head.
He swept the flashlight over the walls again. The carvings here were different. Denser. The spirals tightened inward, converging toward the far wall like currents pulled to a single point. Mineral deposits along the etched lines caught the light and threw it back in fractured angles.
Water dripped steadily in the corner. Pool formation, about six inches deep. Zach crouched beside it. Shone his light across the surface. Clear. Still. Undisturbed.
He let the beam travel once more around the chamber. Stone. Water. Symbols. Nothing else.
The apprehension persisted, slithering up his spine. He didn’t believe in mystical bullshit. He believed in evidence, training, and instinct honed by experience.
The sensation in his gut now was instinct, not magic. His subconscious processing details that his conscious mind hadn’t cataloged yet. Something here wasn’t right.
He stood. Checked the chamber one more time. Nothing.
The feeling didn’t budge.
He filed it away. Turned. Headed back toward daylight.
