Chapter 1

"I’m just saying, if you’d read the footnotes in the *Codex Malum*, we wouldn’t be currently auditioning for the role of human panini!" Kaelen shouted over the screech of stone on stone. He jammed a brass stylus into the central dial of the vault’s meridian, his fingers trembling as he tried to align the celestial symbols.

Jax, his boots planted firmly against the vibrating floor, adjusted his grip on the heavy golden idol tucked under his arm. "And I’m just saying, Kael, that your 'footnotes' didn't mention the floor having a personal vendetta against my hamstrings. Less talking, more scholar-ing!"

The air in the chamber was thick, smelling of ozone and the stagnant breath of a thousand years. Above them, the sapphire runes that provided their only light were fading from a brilliant electric blue to a ghostly, dying violet. With every pulse of the light, the walls of the vault groaned and crept six inches closer. The exit—a massive slab of reinforced limestone—was already halfway to the floor, sealing them into the dark.

"It’s a light-refraction sequence!" Kaelen yelled, squinting at the wall where the dimming blue beams hit a series of mirrors. "I just need to redirect the third beam to the solstice notch. If I miss, the ceiling drops."

"Great plan. Solid. Except for the part where the ceiling is already giving me a haircut," Jax retorted, his usual smirk strained. He jammed his heavy spear into the primary gear housing near the ceiling, the wood groaning under the weight of the descending trap. "I’m losing the leverage here, buddy. If you’ve got a genius move, now’s the time to play it. Or, you know, we could just die. I hear the afterlife has excellent legroom."

Kaelen ignored him, his mind racing through permutations of ancient engineering. He saw the notch. He saw the beam. But as the sapphire light flickered one last time, he realized the mirrors were misaligned by a fraction of a degree—a mechanical error caused by age, or perhaps a final, cruel trick by the architects. The light wouldn't reach the notch. Not by itself.

"Jax! The idol!" Kaelen screamed, spinning around. "The weight! It’s not a light puzzle, it’s a counter-balance! The runes are just a distraction!"

Jax looked at the golden relic, then at the far side of the room where a small, unassuming pressure plate sat beneath a gargoyle’s maw. "You want me to throw the retirement fund? We’ve been chased by three cults and a very angry camel for this thing!"

"Throw it or wear the ceiling as a blanket, Jax! Choose!"

Jax let out a sharp, bark-like laugh, his eyes flashing with the thrill of the gamble. "I told you I was varsity material back in the day. Don't blink."

With a heave that made his muscles bunch against his leather armor, Jax launched the solid gold idol across the shrinking room. It soared through the air, a glint of yellow in the dying blue light, and slammed onto the pressure plate with a resonant *thud*.

For a heartbeat, nothing happened. Then, the grinding stopped. The walls groaned to a halt, leaving barely three feet of space in the center of the room. The exit slab shuddered, hovering just eighteen inches off the floor.

"See?" Jax wheezed, wiping sweat from his brow. "Precision engineering meets mercenary excellence. You’re welcome."

"Don't get cocky," Kaelen snapped, already diving toward the gap. "The secondary mechanism just engaged. That sound isn't the door opening further."

From the dark corridor beyond the gap, a low, metallic growl echoed—the sound of something massive and multi-legged unfolding itself from a stone alcove. The guardian of the outer sanctum was awake.

Kaelen slid under the stone slab first, his robes catching on the grit. Jax followed a second later, barely squeezing his broad shoulders through as the slab gave one final, decisive heave downward, sealing the vault behind them for good.

They stood in the pitch-black tunnel, the sound of heavy, rhythmic footsteps approaching from the shadows ahead. Jax pulled his backup dagger and offered Kaelen a sharp, reckless grin that was visible even in the gloom.

"Well," Jax whispered, his voice echoing off the damp walls. "At least it’s not a puzzle."

Kaelen adjusted his spectacles and gripped his staff, his heart hammering against his ribs. "Shut up, Jax. Just... shut up and run."

Together, they turned toward the oncoming noise, stepping deeper into the dark.
