The walls of the Devil King's palace rose like a fortress birthed from shadow itself, jagged stone slick with the residue of centuries of dark energy. Mia's squad pressed onward along the base, boots scuffing over cracked earth that seemed to drink in light. The further they went from the main battle, the thinner the sound of clashing steel and war cries became, replaced by silence so heavy it felt unnatural.
Mia led them, her sword arm loose but ready, every nerve alert. Behind her, Hiro's sharp eyes darted across every protrusion and shadow. Lisa drifted close to the wall, fingertips sometimes brushing against the stone as if searching for unseen currents of mana. Sylvia moved like a phantom, bow half-raised, gaze always sweeping ahead. Vance trudged further back, restless but more subdued than usual, while Misha's calm, coiled steps carried the aura of someone ready to break into motion at a moment's notice. Zion walked in the rear guard, spear tilted at a diagonal, his silence making him seem like part of the wall itself.
The battle at the gates still thundered in the distance. The human army ground against the Devil King's forces in a war of attrition neither side seemed willing to yield. But here, along the shadowed outer wall, there was no resistance. No patrols. No movement.
And that made Mia uneasy.
The devils were many things—arrogant, violent, cunning—but rarely careless. For the squad to cover this much ground without encountering even a sentry was wrong. Too wrong. The source of thɪs content is novel·fire·net
Then Hiro's voice, quiet but urgent, broke the silence.
At the base of an inward bend in the wall stood a door. Half-hidden beneath overgrowth and warped roots, its surface shimmered faintly as if catching light that wasn't there. It was tall enough for two men, wide enough to admit an armored unit, yet its placement was subtle, almost secret. Carvings etched into its surface spiraled into strange patterns—neither wholly demonic nor human in origin.
A ripple of tension passed through the squad.
"Unbelievable," Vance muttered, his arrogance creeping back. "We've been walking for hours and stumble across a gift ? An unguarded entrance straight into the palace? Fortune favors us."
"Or it's bait," Sylvia countered immediately, arrow half-drawn, eyes narrowed on the frame.
Lisa crouched, studying the markings with a furrowed brow. Her voice was low but firm. "There's no guard detail. No footprints leading here. Nothing to suggest traffic in or out. That's not just suspicious—it's intentional. Doors don't stay unguarded around fortresses unless the masters want them that way."
Zion grunted softly. "A trap, then."
The word settled into the silence like lead.
Mia stepped closer, examining the door. It pulsed faintly beneath her gaze, a rhythm too steady to be natural. She reached out with her mana sense and recoiled almost instantly. The door drank at her energy, subtle but undeniable, as though it wanted to taste her before she even touched it.
She turned sharply. "No one lay a hand on it yet."
Misha broke the quiet with a slow exhale. "Strange. If this was meant for devils, there'd at least be traces of them. Patrols, blood marks, sigils, something. But there's nothing. Just a door… waiting."
Her words mirrored what they were all thinking.
Lisa finally stood, brushing dust from her gloves. "I can probe it. Carefully. A minor weave, just to test its reaction."
Mia weighed the choice. The temptation to leave it alone tugged at her, but the gates were a bloodbath. If this was a true passage inside, their forces desperately needed it. "Do it. But lightly."
Lisa's fingers danced, weaving faint blue runes that glowed like candlelight. She pressed them into the frame. The glow spread, tracing the spirals etched into the surface. For a moment, nothing happened. Then the glow pulsed back at them—once, twice—and died.
Lisa pulled her hand away, lips pressed thin. "Not locked. Not exactly. More like… dormant. As though it's been asleep, waiting for someone to come."
"Someone like us?" Hiro asked, brows furrowing.
Her silence was answer enough.
Sylvia clicked her tongue. "Doors don't sleep. That's not architecture, that's intent."
Vance smirked faintly, though unease lurked in his eyes. "Intent or not, it's still an opening. I say we take the gift before the devils change their minds."
Zion's voice rumbled from the back. "You say that now. You won't be laughing if it shuts behind us."
The group turned their eyes to Mia. She could feel the weight of their stares, their trust pressing down like armor. This was her call. Pull back and they might miss a crucial opportunity. Push forward and they could be walking into a deathtrap.
Her hand settled on the hilt of her sword. "We'll test it first. Sylvia?"
The archer stepped forward without hesitation, her bowstring taut. She loosed an arrow, the shaft streaking into the door. Instead of splintering or bouncing away, the arrow vanished—swallowed whole. No sound of impact. No trace left behind.
"Not good," she muttered. "That wasn't wood. That wasn't stone either."
Lisa moved closer, frowning. "It absorbed the arrow. As if the door itself decided it didn't matter."
Mia's stomach tightened. This wasn't a structure—it was a threshold, one designed to choose.
The air grew colder around them. The faint pulse of the door quickened, as though it recognized it had their attention.
"Look at it," Misha said softly. "It wants us to step through."
That was what chilled Mia most of all.
"Why unguarded?" Hiro murmured, his voice carrying the same thought gnawing at Mia's mind. "The devils aren't careless. They wouldn't leave a path open unless it served them."
Lisa nodded grimly. "It's too perfect. Almost like… it's meant for us and only us."
The group fell silent again, the distant thunder of war muffled by the oppressive quiet of the wall. Each of them stared at the door, their own doubts written across their faces.
Finally, Mia drew in a breath and spoke. "We open it. But slowly. And no one steps inside until we're certain."
Hiro and Vance moved forward, placing their hands against the frame. The door resisted, groaning as it shifted. The sound wasn't wood on hinges—it was bone grinding against bone. The hair on the back of Mia's neck prickled.
A draft spilled out, cold and fetid, carrying with it the stench of earth long sealed away. Shadows curled along the threshold, shifting like living things. Beyond the crack, a faint glow pulsed from a spiraling staircase descending into darkness.
Every instinct screamed danger.
The squad exchanged glances. Their mission was clear, their choices less so.
Mia's voice was steady, though her chest burned with tension. "Decision time. Do we step inside… or walk away?"
The door yawned wider, shadows stretching like a maw ready to swallow them whole.
And still, no guard, no devil, no sign of resistance.
