The chamber of the Heart Engine groaned as if it were a living creature, pulsing violently with every heartbeat of its own design. Sparks showered the metallic floors, scalding steam hissed like serpents through vents, and the rotating gears clashed with deafening screeches.Every inch of the massive chamber throbbed with the sheer power of the machine a power that was now actively reacting to the presence of Marcus, Angela, Aiden, Leona, and the hidden heir.Marcus Hilton pressed himself against a tilted platform, surveying the chaos. His eyes were sharp, calculating. “Everyone hold your positions! The chamber isn’t just reacting it’s attacking! The Heart Engine is alive, and it knows exactly where we are.”Angela’s fingers flew over the control panel she had set up on a mobile command platform. “Marcus I’m detecting fluctuations! The core is overloading! Whatever we triggered in the last surge it’s unstable. If we don’t stabilize it, the entire structure will collapse taking all of

The ground beneath the Heart Engine’s chamber groaned like it was alive, trembling violently with every pulse of the colossal machine. Sparks rained from broken conduits, and jets of scalding steam hissed in every direction.The chamber had become a cage of living steel, a predator with teeth of pistons and claws of molten metal.Aiden clutched the glowing envelope tightly, his knuckles white. “Leona hold on! Whatever’s coming we face it together!”Leona’s hands trembled but never left his. “I’m not letting go, Aiden. Not now. Not ever.”Marcus Hilton braced against a tilted catwalk, scanning the chaos. “Everyone, stay sharp! This isn’t just the Heart Engine reacting something beneath it is rising!”Angela’s fingers flew over the portable console, tracking energy flows from the Heart Engine. “Marcus Aiden the energy readings are off the charts. There’s something massive down there, below the core. Something alive, something ancient. And it’s moving upward!”Before anyone could react,

The abyss beneath the Heart Engine roared like a living leviathan, its tremors rattling every inch of the chamber. Sparks and molten metal hissed into the air, painting the chaos in orange and white streaks.Platforms twisted and shattered. Steel beams groaned under the strain, threatening to collapse at any moment.Aiden clutched the glowing envelope tightly, his pulse resonating in sync with the Heart Engine. “Leona stay close. Whatever comes we face it together!”Leona’s hands trembled but remained locked with his. “I won’t let go, Aiden no matter what.”Above them, Marcus and Angela fought to maintain control of the fragmented catwalks. “The platforms won’t hold much longer!” Marcus shouted, firing at the shadow figure who had regained footing, forcing him to retreat to the chamber’s edge.Angela’s fingers danced over the portable console. “I’m stabilizing energy flows, but it’s not enough! The Heart Engine is alive and whatever’s coming from the abyss it’s hungry!”From the dark

The darkness didn’t come quietly. It slammed into them like a coffin lid. Leona screamed first. “Aiden!”“I’ve got you!” Aiden shouted, arms locking around her as the platform finally gave way. Steel screamed. The Heart Engine’s light flared violently, then dippedflickering like a heart skipping beats.They fell. Not freely. Dragged. Something beneath the chamber pulled them downward, heavier than gravity, stronger than machinery. The abyssal force wrapped invisible pressure around the space itself, crushing air, bending sound.Marcus roared from above, “ANGELA! WE’RE LOSING THEM!”“I KNOW!” Angela shouted back, slamming commands into her console. “The Heart Engine is being suppressed! Something is overriding its safeguards!”Aiden hit hard. Not ground metal ribs, curved and alive, like the inside of a colossal beast. He rolled, shielding Leona as sparks tore past them.Leona coughed. “Aiden where are we?”Aiden lifted his head slowly. His voice went tight. “Inside it.”The Heart Engi
