Mod Superhero - STUBBING AUG 17TH!

Chapter 7.37 - Clara 6 / Heart of the Vault

The last stretch of corridors twisted downward in sharp angles, each one carrying more heat than the last. Arsenal's boots struck the stone in rhythm with Lock's heavier stride and Athena's lighter step, their suits adjusting with every shift in pressure. The air had grown thick enough to feel like they were sprinting through an oven.

Arsenal and Lock could endure it—she could feel the heat pressing against her skin through her thinsuit, but that much heat just made her stronger. Lock could have gone bare-chested into the inferno and laughed about it. But Athena wasn't built for this kind of environment. Her breathing was labored now, even with the nanite suit taking the edge off, and her barriers flickered like they were compensating for the pressure.

It helped that they didn't run into any more guards or traps. It was... eerie. Like the Vault had abandoned its own defense, leaving them to race through hollow arteries where the only resistance came from the mountain's heat and weight.

The descent opened into a chamber that swallowed them whole.

The containment hall stretched three stories high, each wall carved and reinforced with vast suppression sigils that pulsed like the veins of some titanic heart. Machinery the size of buildings lined the sides, each a mix of stone, metal, crystal, and wire. Layers upon layers of enchantments glowed in UV blue. Thick conduits, wider than Arsenal's shoulders, ran from the pillars and vanished through reinforced arches at the far end.

At the end of the hall, past the arches, the world bled into something raw: A vast lake of magma glowing in an unnatural haze. That edge of the demiplane was semipermeable, which caused the entire lake to shimmer in a brilliant UV blue.

For a heartbeat, Arsenal just stood at the edge of the hall, visor filled with shifting heat signatures, the enormity of the place pressing down on her. The Vault was a prison, and this place was a prison of a different kind—a cage built around the veins of the earth.

Lock let out a low whistle. "This, uh... this is something else."

Arsenal couldn't remember the last time she'd heard Lock speechless, and she couldn't blame him.

Meanwhile, Athena wasn't impressed. There was a hint of a smirk in her voice as she caught her breath. "Impressive, but I've seen better."

Lock snapped his head around. "Better than this?"

"The Storm Anchors of Valmere could quell hurricanes and tidal waves. The Mirrors of Kheleris illuminated an entire coastline. And the Iron Aqueducts—well, let's just say they made this look like plumbing."

Lock scoffed. "Now you're just making things up."

Athena just shrugged. "Saw them myself."

Arsenal tuned out the exchange, her gaze fixed on the far end of the hall. Even through layers of stone and spellwork, she could feel the lake of magma, like a second heartbeat in her chest. Each pulse resonated within her, echoing through her chest, her bones, and her skull—overwhelming, almost to the point of pain. The lake felt raw and alive, and like Arsenal was on the edge of a living star.

Like it was calling to her.

Arsenal's fingers flexed at her sides, gauntlets humming faintly with apprehension. She forced her breathing steady.

Mod's voice came through the comms. "You ready to do this?"

Arsenal exhaled once. "As ready as I'll ever be. Tell me what to do..."

The floor stirred. At first it looked like dust, but then the granules thickened, darkened, and began to move with purpose. Black sand spilled across the sigil-carved stone, cords of nanites threading toward her boots like snakes drawn to warmth.
